Rehnquist Court: California v. Greenwood
Your Garbage is Not Private
US Supreme Court
 CALIFORNIA v. GREENWOOD, 486 U.S. 35 (1988)
 486 U.S. 35
 CALIFORNIA v. GREENWOOD ET AL.
 CERTIORARI TO THE COURT OF APPEAL OF CALIFORNIA, FOURTH APPELLATE DISTRICT
               
               No. 86-684.
 
 Argued January 11, 1988
 Decided May 16, 1988
               
               
 Acting on information indicating that respondent Greenwood might be engaged in narcotics
                  trafficking, police twice obtained from his regular trash collector garbage bags left
                  on the curb in front of his house. On the basis of items in the bags which were indicative
                  of narcotics use, the police obtained warrants to search the house, discovered controlled
                  substances during the searches, and arrested respondents on felony narcotics charges.
                  Finding that probable cause to search the house would not have existed without the
                  evidence obtained from the trash searches, the State Superior Court dismissed the
                  charges under People v. Krivda, 5 Cal. 3d 357, 486 P.2d 1262, which held that warrantless
                  trash searches violate the Fourth Amendment and the California Constitution. Although
                  noting a post-Krivda state constitutional amendment eliminating the exclusionary rule
                  for evidence seized in violation of state, but not federal, law, the State Court of
                  Appeal affirmed on the ground that Krivda was based on federal, as well as state,
                  law.
 Held:
 1. The Fourth Amendment does not prohibit the warrantless search and seizure of garbage
                  left for collection outside the curtilage of a home. Pp. 39-44.
 (a) Since respondents voluntarily left their trash for collection in an area particularly
                  suited for public inspection, their claimed expectation of privacy in the inculpatory
                  items they discarded was not objectively reasonable. It is common knowledge that plastic
                  garbage bags left along a public street are readily accessible to animals, children,
                  scavengers, snoops, and other members of the public. Moreover, respondents placed
                  their refuse at the curb for the express purpose of conveying it to a third party,
                  the trash collector, who might himself have sorted through it or permitted others,
                  such as the police, to do so. The police cannot reasonably be expected to avert their
                  eyes from evidence of criminal activity that could have been observed by any member
                  of the public. Pp. 39-43.
 (b) Greenwood's alternative argument that his expectation of privacy in his garbage
                  should be deemed reasonable as a matter of federal constitutional law because the
                  warrantless search and seizure of his garbage was impermissible as a matter of California
                  law under Krivda, [486 U.S. 35, 36] which he contends survived the state constitutional
                  amendment, is without merit. The reasonableness of a search for Fourth Amendment purposes
                  does not depend upon privacy concepts embodied in the law of the particular State
                  in which the search occurred; rather, it turns upon the understanding of society as
                  a whole that certain areas deserve the most scrupulous protection from government
                  invasion. There is no such understanding with respect to garbage left for collection
                  at the side of a public street. Pp. 43-44.
 2. Also without merit is Greenwood's contention that the California constitutional
                  amendment violates the Due Process Clause of the Fourteenth Amendment. Just as this
                  Court's Fourth Amendment exclusionary rule decisions have not required suppression
                  where the benefits of deterring minor police misconduct were overbalanced by the societal
                  costs of exclusion, California was not foreclosed by the Due Process Clause from concluding
                  that the benefits of excluding relevant evidence of criminal activity do not outweigh
                  the costs when the police conduct at issue does not violate federal law. Pp. 44-45.

 JUSTICE WHITE delivered the opinion of the Court.
 The issue here is whether the Fourth Amendment prohibits the warrantless search and
                  seizure of garbage left for collection outside the curtilage of a home. We conclude,
                  in accordance with the vast majority of lower courts that have addressed the issue,
                  that it does not.
 I
 In early 1984, Investigator Jenny Stracner of the Laguna Beach Police Department
                  received information indicating that respondent Greenwood might be engaged in narcotics
                  trafficking. Stracner learned that a criminal suspect had informed a federal drug
                  enforcement agent in February 1984 that a truck filled with illegal drugs was en route
                  to the Laguna Beach address at which Greenwood resided. In addition, a neighbor complained
                  of heavy vehicular traffic late at night in front of Greenwood's single-family home.
                  The neighbor reported that the vehicles remained at Greenwood's house for only a few
                  minutes.
 Stracner sought to investigate this information by conducting a surveillance of Greenwood's
                  home. She observed several vehicles make brief stops at the house during the late-night
                  and early morning hours, and she followed a truck from the house to a residence that
                  had previously been under investigation as a narcotics-trafficking location.
 On April 6, 1984, Stracner asked the neighborhood's regular trash collector to pick
                  up the plastic garbage bags that Greenwood had left on the curb in front of his house
                  and to turn the bags over to her without mixing their contents with garbage from other
                  houses. The trash collector cleaned his truck bin of other refuse, collected the garbage
                  bags from the street in front of Greenwood's house, and turned the bags over to Stracner.
                  The officer searched through the rubbish [486 U.S. 35, 38] and found items indicative
                  of narcotics use. She recited the information that she had gleaned from the trash
                  search in an affidavit in support of a warrant to search Greenwood's home.
 Police officers encountered both respondents at the house later that day when they
                  arrived to execute the warrant. The police discovered quantities of cocaine and hashish
                  during their search of the house. Respondents were arrested on felony narcotics charges.
                  They subsequently posted bail.
 The police continued to receive reports of many late-night visitors to the Greenwood
                  house. On May 4, Investigator Robert Rahaeuser obtained Greenwood's garbage from the
                  regular trash collector in the same manner as had Stracner. The garbage again contained
                  evidence of narcotics use.
 Rahaeuser secured another search warrant for Greenwood's home based on the information
                  from the second trash search. The police found more narcotics and evidence of narcotics
                  trafficking when they executed the warrant. Greenwood was again arrested.
 The Superior Court dismissed the charges against respondents on the authority of
                  People v. Krivda, 5 Cal. 3d 357, 486 P.2d 1262 (1971), which held that warrantless
                  trash searches violate the Fourth Amendment and the California Constitution. The court
                  found that the police would not have had probable cause to search the Greenwood home
                  without the evidence obtained from the trash searches.
 The Court of Appeal affirmed. 182 Cal. App. 3d 729, 227 Cal. Rptr. 539 (1986). The
                  court noted at the outset that the fruits of warrantless trash searches could no longer
                  be suppressed if Krivda were based only on the California Constitution, because since
                  1982 the State has barred the suppression of evidence seized in violation of California
                  law but not federal law. See Cal. Const., Art. I, 28(d); In re Lance W., 37 Cal. 3d
                  873, 694 P.2d 744 (1985). But Krivda, a decision binding on the Court of Appeal, also
                  held that the fruits of warrantless trash searches were to be excluded under federal
                  [486 U.S. 35, 39] law. Hence, the Superior Court was correct in dismissing the charges
                  against respondents. 182 Cal. App. 3d, at 735, 227 Cal. Rptr, at 542. 1
 The California Supreme Court denied the State's petition for review of the Court
                  of Appeal's decision. We granted certiorari, 483 U.S. 1019 , and now reverse.
 II
 The warrantless search and seizure of the garbage bags left at the curb outside the
                  Greenwood house would violate the Fourth Amendment only if respondents manifested
                  a subjective expectation of privacy in their garbage that society accepts as objectively
                  reasonable. O'Connor v. Ortega, 480 U.S. 709, 715 (1987); California v. Ciraolo, 476
                  U.S. 207, 211 (1986); Oliver v. United States, 466 U.S. 170, 177 (1984); Katz v. United
                  States, 389 U.S. 347, 361 (1967) (Harlan, J., concurring). Respondents do not disagree
                  with this standard.
 They assert, however, that they had, and exhibited, an expectation of privacy with
                  respect to the trash that was searched by the police: The trash, which was placed
                  on the street for collection at a fixed time, was contained in opaque plastic bags,
                  which the garbage collector was expected to pick up, mingle with the trash of others,
                  and deposit at the garbage dump. The trash was only temporarily on the street, and
                  there was little likelihood that it would be inspected by anyone.
 It may well be that respondents did not expect that the contents of their garbage
                  bags would become known to the police or other members of the public. An expectation
                  of privacy does not give rise to Fourth Amendment protection, [486 U.S. 35, 40] however,
                  unless society is prepared to accept that expectation as objectively reasonable.
 Here, we conclude that respondents exposed their garbage to the public sufficiently
                  to defeat their claim to Fourth Amendment protection. It is common knowledge that
                  plastic garbage bags left on or at the side of a public street are readily accessible
                  to animals, 2 children, scavengers, 3 snoops, 4 and other members of the public. See
                  Krivda, supra, at 367, 486 P.2d, at 1269. Moreover, respondents placed their refuse
                  at the curb for the express purpose of conveying it to a third party, the trash collector,
                  who might himself have sorted through respondents' trash or permitted others, such
                  as the police, to do so. Accordingly, having deposited their garbage "in an area particularly
                  suited for [486 U.S. 35, 41] public inspection and, in a manner of speaking, public
                  consumption, for the express purpose of having strangers take it," United States v.
                  Reicherter, 647 F.2d 397, 399 (CA3 1981), respondents could have had no reasonable
                  expectation of privacy in the inculpatory items that they discarded.
 Furthermore, as we have held, the police cannot reasonably be expected to avert their
                  eyes from evidence of criminal activity that could have been observed by any member
                  of the public. Hence, "[w]hat a person knowingly exposes to the public, even in his
                  own home or office, is not a subject of Fourth Amendment protection." Katz v. United
                  States, supra, at 351. We held in Smith v. Maryland, 442 U.S. 735 (1979), for example,
                  that the police did not violate the Fourth Amendment by causing a pen register to
                  be installed at the telephone company's offices to record the telephone numbers dialed
                  by a criminal suspect. An individual has no legitimate expectation of privacy in the
                  numbers dialed on his telephone, we reasoned, because he voluntarily conveys those
                  numbers to the telephone company when he uses the telephone. Again, we observed that
                  "a person has no legitimate expectation of privacy in information he voluntarily turns
                  over to third parties." Id., at 743-744.
 Similarly, we held in California v. Ciraolo, supra, that the police were not required
                  by the Fourth Amendment to obtain a warrant before conducting surveillance of the
                  respondent's fenced backyard from a private plane flying at an altitude of 1,000 feet.
                  We concluded that the respondent's expectation that his yard was protected from such
                  surveillance was unreasonable because "[a]ny member of the public flying in this airspace
                  who glanced down could have seen everything that these officers observed." Id., at
                  213-214.
 Our conclusion that society would not accept as reasonable respondents' claim to
                  an expectation of privacy in trash left for collection in an area accessible to the
                  public is reinforced by the unanimous rejection of similar claims by the Federal Courts
                  of Appeals. See United States v. Dela Espriella, [486 U.S. 35, 42] 781 F.2d 1432,
                  1437 (CA9 1986); United States v. O'Bryant, 775 F.2d 1528, 1533-1534 (CA11 1985);
                  United States v. Michaels, 726 F.2d 1307, 1312-1313 (CA8), cert. denied, 469 U.S.
                  820 (1984); United States v. Kramer, 711 F.2d 789, 791-794 (CA7), cert. denied, 464
                  U.S. 962 (1983); United States v. Terry, 702 F.2d 299, 308-309 (CA2), cert. denied
                  sub nom. Williams v. United States, 461 U.S. 931 (1983); United States v. Reicherter,
                  supra, at 399; United States v. Vahalik, 606 F.2d 99, 100-101 (CA5 1979) (per curiam),

                  In United States v. Thornton, 241 U.S. App. D.C. 46, 56, and n. 11, 746 F.2d 39, 49,
                  and n. 11 (1984), the court observed that "the overwhelming weight of authority rejects
                  the proposition that a reasonable expectation of privacy exists with respect to trash
                  discarded outside the home and the curtilege [sic] thereof." In addition, of those
                  state appellate courts that have considered the issue, the vast majority have held
                  that the police may conduct warrantless searches and seizures of garbage discarded
                  in public areas. See Commonwealth v. Chappee, 397 Mass. 508, 512-513, 492 N. E. 2d

 III
 We reject respondent Greenwood's alternative argument for affirmance: that his expectation
                  of privacy in his garbage should be deemed reasonable as a matter of federal constitutional
                  law because the warrantless search and seizure of his garbage was impermissible as
                  a matter of California law. He urges that the state-law right of Californians to privacy
                  in their garbage, announced by the California Supreme Court in Krivda, supra, survived
                  the subsequent state constitutional amendment eliminating the suppression remedy as
                  a means of enforcing that right. See In re Lance W., 37 Cal. 3d, at 886-887, 694 P.2d,
                  at 752-753. Hence, he argues that the Fourth Amendment should itself vindicate that
                  right.
 Individual States may surely construe their own constitutions as imposing more stringent
                  constraints on police conduct than does the Federal Constitution. We have never intimated,
                  however, that whether or not a search is reasonable within the meaning of the Fourth
                  Amendment depends on the law of the particular State in which the search occurs. We
                  have emphasized instead that the Fourth Amendment analysis must turn on such factors
                  as "our societal understanding that certain areas deserve the most scrupulous protection
                  from government invasion." Oliver v. United States, 466 U.S., at 178 (emphasis added).
                  See also Rakas v. Illinois, 439 U.S. 128, 143 -144, n. 12 (1978). We have already
                  concluded that society as a whole possesses no such understanding [486 U.S. 35, 44]
                  with regard to garbage left for collection at the side of a public street. Respondent's
                  argument is no less than a suggestion that concepts of privacy under the laws of each
                  State are to determine the reach of the Fourth Amendment. We do not accept this submission.

 Greenwood finally urges as an additional ground for affirmance that the California
                  constitutional amendment eliminating the exclusionary rule for evidence seized in
                  violation of state but not federal law violates the Due Process Clause of the Fourteenth
                  Amendment. In his view, having recognized a state-law right to be free from warrantless
                  searches of garbage, California may not under the Due Process Clause deprive its citizens
                  of what he describes as "the only effective deterrent" to violations of this right.
                  Greenwood concedes that no direct support for his position can be found in the decisions
                  of this Court. He relies instead on cases holding that individuals are entitled to
                  certain procedural protections before they can be deprived of a liberty or property
                  interest created by state law. See Hewitt v. Helms, 459 U.S. 460 (1983); Vitek v.
                  Jones, 445 U.S. 480 (1980).
 We see no merit in Greenwood's position. California could amend its Constitution
                  to negate the holding in Krivda that state law forbids warrantless searches of trash.
                  We are convinced that the State may likewise eliminate the exclusionary rule as a
                  remedy for violations of that right. At the federal level, we have not required that
                  evidence obtained in violation of the Fourth Amendment be suppressed in all circumstances.
                  See, e. g., United States v. Leon, 468 U.S. 897 (1984); United States v. Janis, 428
                  U.S. 433 (1976); United States v. Calandra, 414 U.S. 338 (1974). Rather, our decisions
                  concerning the scope of the Fourth Amendment exclusionary rule have balanced the benefits
                  of deterring police misconduct against the costs of excluding reliable evidence of
                  criminal activity. See Leon, 468 U.S., at 908 -913. We [486 U.S. 35, 45] have declined
                  to apply the exclusionary rule indiscriminately "when law enforcement officers have
                  acted in objective good faith or their transgressions have been minor," because "the
                  magnitude of the benefit conferred on . . . guilty defendants [in such circumstances]
                  offends basic concepts of the criminal justice system." Id., at 908 (citing Stone
                  v. Powell, 428 U.S. 465, 490 (1976)).
 The States are not foreclosed by the Due Process Clause from using a similar balancing
                  approach to delineate the scope of their own exclusionary rules. Hence, the people
                  of California could permissibly conclude that the benefits of excluding relevant evidence
                  of criminal activity do not outweigh the costs when the police conduct at issue does
                  not violate federal law.

 The judgment of the California Court of Appeal is therefore reversed, and this case
                  is remanded for further proceedings not inconsistent with this opinion.
 It is so ordered.
 JUSTICE KENNEDY took no part in the consideration or decision of this case.

 [ Footnote 1 ] The Court of Appeal also held that respondent Van Houten had standing
                  to seek the suppression of evidence discovered during the April 4 search of Greenwood's
                  home. 182 Cal. App. 3d, at 735, 227 Cal. Rptr., at 542-543.
 [ Footnote 2 ] For example, State v. Ronngren, 361 N. W. 2d 224 (N. D. 1985), involved
                  the search of a garbage bag that a dog, acting "at the behest of no one," id., at
                  228, had dragged from the defendants' yard into the yard of a neighbor. The neighbor
                  deposited the bag in his own trash can, which he later permitted the police to search.
                  The North Dakota Supreme Court held that the search of the garbage bag did not violate
                  the defendants' Fourth Amendment rights.
 [ Footnote 3 ] It is not only the homeless of the Nation's cities who make use of
                  others' refuse. For example, a nationally syndicated consumer columnist has suggested
                  that apartment dwellers obtain cents-off coupons by "mak[ing] friends with the fellow
                  who handles the trash" in their buildings, and has recounted the tale of "the `Rich
                  lady' from Westmont who once a week puts on rubber gloves and hip boots and wades
                  into the town garbage dump looking for labels and other proofs of purchase" needed
                  to obtain manufacturers' refunds. M. Sloane, "The Supermarket Shopper's" 1980 Guide
                  to Coupons and Refunds 74, 161 (1980).
 [ Footnote 4 ] Even the refuse of prominent Americans has not been invulnerable.
                  In 1975, for example, a reporter for a weekly tabloid seized five bags of garbage
                  from the sidewalk outside the home of Secretary of State Henry Kissinger. Washington
                  Post, July 9, 1975, p. A1, col. 8. A newspaper editorial criticizing this journalistic
                  "trash-picking" observed that "[e]vidently . . . `everybody does it.'" Washington
                  Post, July 10, 1975, p. A18, col. 1. We of course do not, as the dissent implies,
                  "bas[e] [our] conclusion" that individuals have no reasonable expectation of privacy
                  in their garbage on this "sole incident." Post, at 51.
 [ Footnote 5 ] Given that the dissenters are among the tiny minority of judges whose
                  views are contrary to ours, we are distinctly unimpressed with the dissent's prediction
                  that "society will be shocked to learn" of today's decision. Post, at 46.
 JUSTICE BRENNAN, with whom JUSTICE MARSHALL joins, dissenting.
 Every week for two months, and at least once more a month later, the Laguna Beach
                  police clawed through the trash that respondent Greenwood left in opaque, sealed bags
                  on the curb outside his home. Record 113. Complete strangers minutely scrutinized
                  their bounty, undoubtedly dredging up intimate details of Greenwood's private life
                  and habits. The intrusions proceeded without a warrant, and no court before or since
                  has concluded that the police acted on probable cause to believe Greenwood was engaged
                  in any criminal activity.
 Scrutiny of another's trash is contrary to commonly accepted notions of civilized
                  behavior. I suspect, therefore, [486 U.S. 35, 46] that members of our society will
                  be shocked to learn that the Court, the ultimate guarantor of liberty, deems unreasonable
                  our expectation that the aspects of our private lives that are concealed safely in
                  a trash bag will not become public.

 "A container which can support a reasonable expectation of privacy may not be searched,
                  even on probable cause, without a warrant." United States v. Jacobsen, 466 U.S. 109,
                  120 , n. 17 (1984) (citations omitted). Thus, as the Court observes, if Greenwood
                  had a reasonable expectation that the contents of the bags that he placed on the curb
                  would remain private, the warrantless search of those bags violated the Fourth Amendment.
                  Ante, at 39.
 The Framers of the Fourth Amendment understood that "unreasonable searches" of "paper[s]
                  and effects" - no less than "unreasonable searches" of "person[s] and houses" - infringe
                  privacy. As early as 1878, this Court acknowledged that the contents of "[l]etters
                  and sealed packages . . . in the mail are as fully guarded from examination and inspection
                  . . . as if they were retained by the parties forwarding them in their own domiciles."
                  Ex parte Jackson, 96 U.S. 727, 733 . In short, so long as a package is "closed against
                  inspection," the Fourth Amendment protects its contents, "wherever they may be," and
                  the police must obtain a warrant to search it just "as is required when papers are
                  subjected to search in one's own household." Ibid. Accord, United States v. Van Leeuwen,
                  397 U.S. 249 (1970).
 With the emergence of the reasonable-expectation-of-privacy analysis, see Katz v.
                  United States, 389 U.S. 347, 361 (1967) (Harlan, J., concurring); Smith v. Maryland,
                  442 U.S. 735, 740 (1979), we have reaffirmed this fundamental principle. In Robbins
                  v. California, 453 U.S. 420 (1981), for example, Justice Stewart, writing for a plurality
                  of four, pronounced that "unless the container is such that its contents may be said
                  to be in plain view, those contents are fully [486 U.S. 35, 47] protected by the Fourth
                  Amendment," id., at 427, and soundly rejected any distinction for Fourth Amendment
                  purposes among various opaque, sealed containers:
 "[E]ven if one wished to import such a distinction into the Fourth Amendment, it
                  is difficult if not impossible to perceive any objective criteria by which that task
                  might be accomplished. What one person may put into a suitcase, another may put into
                  a paper bag. . . . And . . . no court, no constable, no citizen, can sensibly be asked
                  to distinguish the relative `privacy interests' in a closed suitcase, briefcase, portfolio,
                  duffelbag, or box." Id., at 426-427.
 See also id., at 428 (expectation of privacy attaches to any container unless it
                  "so clearly announce[s] its contents, whether by its distinctive configuration, its
                  transparency, or otherwise, that its contents are obvious to an observer"). With only
                  one exception, every Justice who wrote in that case eschewed any attempt to distinguish
                  "worthy" from "unworthy" containers. 1
 More recently, in United States v. Ross, 456 U.S. 798 (1982), the Court, relying
                  on the "virtually unanimous agreement [486 U.S. 35, 48] in Robbins . . . that a constitutional
                  distinction between `worthy' and `unworthy' containers would be improper," held that
                  a distinction among "paper bags, locked trunks, lunch buckets, and orange crates"
                  would be inconsistent with
 "the central purpose of the Fourth Amendment. . . . [A] traveler who carries a toothbrush
                  and a few articles of clothing in a paper bag or knotted scarf [may] claim an equal
                  right to conceal his possessions from official inspection as the sophisticated executive
                  with the locked attache case.
 "As Justice Stewart stated in Robbins, the Fourth Amendment provides protection to
                  the owner of every container that conceals its contents from plain view." Id., at
                  822-823 (emphasis added; footnote and citation omitted).
 See also Jacobsen, supra, at 129 (opinion of WHITE, J.).
 Accordingly, we have found a reasonable expectation of privacy in the contents of
                  a 200-pound "double-locked footlocker," United States v. Chadwick, 433 U.S. 1, 11
                  (1977); a "comparatively small, unlocked suitcase," Arkansas v. Sanders, 442 U.S.
                  753, 762 , n. 9 (1979); a "totebag," Robbins, 453 U.S., at 422 ; and "packages wrapped
                  in green opaque plastic," ibid. See also Ross, supra, at 801, 822-823 (suggesting
                  that a warrant would have been required to search a "`lunch-type' brown paper bag"
                  and a "zippered red leather pouch" had they not been found in an automobile); Jacobsen,
                  supra, at 111, 114-115 (suggesting that a warrantless search of an "ordinary cardboard
                  box wrapped in brown paper" would have violated the Fourth Amendment had a private
                  party not already opened it).
 Our precedent, therefore, leaves no room to doubt that had respondents been carrying
                  their personal effects in opaque, sealed plastic bags - identical to the ones they
                  placed on the curb - their privacy would have been protected from warrantless police
                  intrusion. So far as Fourth Amendment protection is concerned, opaque plastic bags
                  are every bit as [486 U.S. 35, 49] worthy as "packages wrapped in green opaque plastic"
                  and "double-locked footlocker[s]." Cf. Robbins, supra, at 441 (REHNQUIST, J., dissenting)
                  (objecting to Court's discovery of reasonable expectation of privacy in contents of
                  "two plastic garbage bags").
 II
 Respondents deserve no less protection just because Greenwood used the bags to discard
                  rather than to transport his personal effects. Their contents are not inherently any
                  less private, and Greenwood's decision to discard them, at least in the manner in
                  which he did, does not diminish his expectation of privacy. 2 [486 U.S. 35, 50]
 A trash bag, like any of the above-mentioned containers, "is a common repository
                  for one's personal effects" and, even more than many of them, is "therefore . . .
                  inevitably associated with the expectation of privacy." Sanders, supra, at 762 (citing
                  Chadwick, supra, at 13). "[A]lmost every human activity ultimately manifests itself
                  in waste products . . . ." Smith v. State, 510 P.2d 793, 798 (Alaska), cert. denied,
                  414 U.S. 1086 (1973). See California v. Rooney, 483 U.S. 307, 320 -321, n. 3 (1987)
                  (WHITE, J., dissenting) (renowned archaeologist Emil Haury once said, "[i]f you want
                  to know what is really going on in a community, look at its garbage") (quoted by W.
                  Rathje, Archaeological Ethnography . . . Because Sometimes It Is Better to Give Than
                  to Receive, in Explorations in Ethnoarchaeology 49, 54 (R. Gould ed. 1978)); Weberman,
                  The Art of Garbage Analysis: You Are What You Throw Away, 76 Esquire 113 (1971) (analyzing
                  trash of various celebrities and drawing conclusions about their private lives). A
                  single bag of trash testifies eloquently to the eating, reading, and recreational
                  habits of the person who produced it. A search of trash, like a search of the bedroom,
                  can relate intimate details about sexual practices, health, and personal hygiene.
                  Like riffling through desk drawers or intercepting phone calls, rummaging through
                  trash can divulge the target's financial and professional status, political affiliations
                  and inclinations, private thoughts, personal relationships, and romantic interests.
                  It cannot be doubted that a sealed trash bag harbors telling evidence of the "intimate
                  activity associated with the `sanctity of a man's home and the privacies of life,'"
                  which the Fourth Amendment is designed [486 U.S. 35, 51] to protect. Oliver v. United
                  States, 466 U.S. 170, 180 (1984) (quoting Boyd v. United States, 116 U.S. 616, 630
                  (1886)). See also United States v. Dunn, 480 U.S. 294, 300 (1987).
 The Court properly rejects the State's attempt to distinguish trash searches from
                  other searches on the theory that trash is abandoned and therefore not entitled to
                  an expectation of privacy. As the author of the Court's opinion observed last Term,
                  a defendant's "property interest [in trash] does not settle the matter for Fourth
                  Amendment purposes, for the reach of the Fourth Amendment is not determined by state
                  property law." Rooney, supra, at 320 (WHITE, J., dissenting). In evaluating the reasonableness
                  of Greenwood's expectation that his sealed trash bags would not be invaded, the Court
                  has held that we must look to "understandings that are recognized and permitted by
                  society." 3 Most of us, I believe, would be incensed to discover a meddler - whether
                  a neighbor, a reporter, or a detective - scrutinizing our sealed trash containers
                  to discover some detail of our personal lives. See State v. Schultz, 388 So.2d 1326,
                  1331 (Fla. App. 1980) (Anstead, J., dissenting). That was, quite naturally, the reaction
                  to the sole incident on which the Court bases its conclusion that "snoops" and the
                  like defeat the expectation of privacy in trash. Ante, at 40, and n. 4. When a tabloid
                  reporter examined then-Secretary of State [486 U.S. 35, 52] Henry Kissinger's trash
                  and published his findings, Kissinger was "really revolted" by the intrusion and his
                  wife suffered "grave anguish." N. Y. Times, July 9, 1975, p. A1, col. 8. The public
                  response roundly condemning the reporter demonstrates that society not only recognized
                  those reactions as reasonable, but shared them as well. Commentators variously characterized
                  his conduct as "a disgusting invasion of personal privacy," Flieger, Investigative
                  Trash, U.S. News & World Report, July 28, 1975, p. 72 (editor's page); "indefensible
                  . . . as civilized behavior," Washington Post, July 10, 1975, p. A18, col. 1 (editorial);
                  and contrary to "the way decent people behave in relation to each other," ibid.
 Beyond a generalized expectation of privacy, many municipalities, whether for reasons
                  of privacy, sanitation, or both, reinforce confidence in the integrity of sealed trash
                  containers by "prohibit[ing] anyone, except authorized employees of the Town . . .,
                  to rummage into, pick up, collect, move or otherwise interfere with articles or materials
                  placed on . . . any public street for collection." United States v. Dzialak, 441 F.2d
                  212, 215 (CA2 1971) (paraphrasing ordinance for town of Cheektowaga, New York). See
                  also United States v. Vahalik, 606 F.2d 99, 100 (CA5 1979) (per curiam); Magda v.
                  Benson, 536 F.2d 111, 112 (CA6 1976) (per curiam); People v. Rooney, 175 Cal. App.
                  3d 634, 645, 221 Cal. Rptr. 49, 56 (1985), cert. dism'd, 483 U.S. 307 (1987); People
                  v. Krivda, 5 Cal. 3d 357, 366, 486 P.2d 1262, 1268 (1971), vacated and remanded, 409

                  n. 3 (1984). In fact, the California Constitution, as interpreted by the State's highest
                  court, guarantees a right of privacy in trash vis-a-vis government officials. See
                  Krivda, supra (recognizing right); In re Lance W., 37 Cal. 3d 873, 886-887, 694 P.2d
                  744, 752-753 (1985) (later constitutional amendment abolished exclusionary remedy
                  but left intact the substance of the right). [486 U.S. 35, 53]
 That is not to deny that isolated intrusions into opaque, sealed trash containers
                  occur. When, acting on their own, "animals, children, scavengers, snoops, [or] other
                  members of the public," ante, at 40 (footnotes omitted), actually rummage through
                  a bag of trash and expose its contents to plain view, "police cannot reasonably be
                  expected to avert their eyes from evidence of criminal activity that could have been
                  observed by any member of the public," ante, at 41. That much follows from cases like
                  Jacobsen, 466 U.S., at 117 , 120, n. 17 (emphasis added), which held that police may
                  constitutionally inspect a package whose "integrity" a private carrier has already
                  "compromised," because "[t]he Fourth Amendment is implicated only if the authorities
                  use information with respect to which the expectation of privacy has not already been
                  frustrated"; and California v. Ciraolo, 476 U.S. 207, 213 -214 (1986) (emphasis added),
                  which held that the Fourth Amendment does not prohibit police from observing what
                  "[a]ny member of the public flying in this airspace who glanced down could have seen."
 Had Greenwood flaunted his intimate activity by strewing his trash all over the curb
                  for all to see, or had some nongovernmental intruder invaded his privacy and done
                  the same, I could accept the Court's conclusion that an expectation of privacy would
                  have been unreasonable. Similarly, had police searching the city dump run across incriminating
                  evidence that, despite commingling with the trash of others, still retained its identity
                  as Greenwood's, we would have a different case. But all that Greenwood "exposed .
                  . . to the public," ante, at 40, were the exteriors of several opaque, sealed containers.
                  Until the bags were opened by police, they hid their contents from the public's view
                  every bit as much as did Chadwick's double-locked footlocker and Robbins' green, plastic
                  wrapping. Faithful application of the warrant requirement does not require police
                  to "avert their eyes from evidence of criminal activity that could have been observed
                  by any member of the public." Rather, it only requires them [486 U.S. 35, 54] to adhere
                  to norms of privacy that members of the public plainly acknowledge.
 The mere possibility that unwelcome meddlers might open and rummage through the containers
                  does not negate the expectation of privacy in their contents any more than the possibility
                  of a burglary negates an expectation of privacy in the home; or the possibility of
                  a private intrusion negates an expectation of privacy in an unopened package; or the
                  possibility that an operator will listen in on a telephone conversation negates an
                  expectation of privacy in the words spoken on the telephone. "What a person . . .
                  seeks to preserve as private, even in an area accessible to the public, may be constitutionally
                  protected." Katz, 389 U.S., at 351 -352. We have therefore repeatedly rejected attempts
                  to justify a State's invasion of privacy on the ground that the privacy is not absolute.
                  See Chapman v. United States, 365 U.S. 610, 616 -617 (1961) (search of a house invaded
                  tenant's Fourth Amendment rights even though landlord had authority to enter house
                  for some purposes); Stoner v. California, 376 U.S. 483, 487 -490 (1964) (implicit
                  consent to janitorial personnel to enter motel room does not amount to consent to
                  police search of room); O'Connor v. Ortega, 480 U.S. 709, 717 (1987) (a government
                  employee has a reasonable expectation of privacy in his office, even though "it is
                  the nature of government offices that others - such as fellow employees, supervisors,
                  consensual visitors, and the general public - may have frequent access to an individual's
                  office"). As JUSTICE SCALIA aptly put it, the Fourth Amendment protects "privacy .
                  . . not solitude." O'Connor, supra, at 730 (opinion concurring in judgment).
 Nor is it dispositive that "respondents placed their refuse at the curb for the express
                  purpose of conveying it to a third party, . . . who might himself have sorted through
                  respondents' trash or permitted others, such as the police, to do so." Ante, at 40.
                  In the first place, Greenwood can hardly be faulted for leaving trash on his curb
                  when a county ordinance [486 U.S. 35, 55] commanded him to do so, Orange County Code
                  4-3-45(a) (1986) (must "remov[e] from the premises at least once each week" all "solid
                  waste created, produced or accumulated in or about [his] dwelling house"), and prohibited
                  him from disposing of it in any other way, see Orange County Code 3-3-85 (1988) (burning
                  trash is unlawful). Unlike in other circumstances where privacy is compromised, Greenwood
                  could not "avoid exposing personal belongings . . . by simply leaving them at home."
                  O'Connor, supra, at 725. More importantly, even the voluntary relinquishment of possession
                  or control over an effect does not necessarily amount to a relinquishment of a privacy
                  expectation in it. Were it otherwise, a letter or package would lose all Fourth Amendment
                  protection when placed in a mailbox or other depository with the "express purpose"
                  of entrusting it to the postal officer or a private carrier; those bailees are just
                  as likely as trash collectors (and certainly have greater incentive) to "sor[t] through"
                  the personal effects entrusted to them, "or permi[t] others, such as police to do
                  so." Yet, it has been clear for at least 110 years that the possibility of such an
                  intrusion does not justify a warrantless search by police in the first instance. See
                  Ex parte Jackson, 96 U.S. 727 (1878); United States v. Van Leeuwen, 397 U.S. 249 (1970);
                  United States v. Jacobsen, supra. 4
 III
 In holding that the warrantless search of Greenwood's trash was consistent with the
                  Fourth Amendment, the Court paints a grim picture of our society. It depicts a society
                  in which local authorities may command their citizens to dispose of their personal
                  effects in the manner least protective of the [486 U.S. 35, 56] "sanctity of [the]
                  home and the privacies of life," Boyd v. United States, 116 U.S., at 630 , and then
                  monitor them arbitrarily and without judicial oversight - a society that is not prepared
                  to recognize as reasonable an individual's expectation of privacy in the most private
                  of personal effects sealed in an opaque container and disposed of in a manner designed
                  to commingle it imminently and inextricably with the trash of others. Ante, at 39.
                  The American society with which I am familiar "chooses to dwell in reasonable security
                  and freedom from surveillance," Johnson v. United States, 333 U.S. 10, 14 (1948),
                  and is more dedicated to individual liberty and more sensitive to intrusions on the
                  sanctity of the home than the Court is willing to acknowledge.
 I dissent.
 [ Footnote 1 ] See 453 U.S., at 436 (BLACKMUN, J., dissenting); id., at 437 (REHNQUIST,
                  J., dissenting); id., at 444 (STEVENS, J., dissenting). But see id., at 433-434 (Powell,
                  J., concurring in judgment) (rejecting position that all containers, even "the most
                  trivial," like "a cigarbox or a Dixie cup," are entitled to the same Fourth Amendment
                  protection). Cf. New York v. Belton, 453 U.S. 454, 460 -461, n. 4 (1981) (defining
                  "container," for purposes of search incident to a lawful custodial arrest, as "any
                  object capable of holding another object," including "luggage, boxes, bags, clothing,
                  and the like"). In addition to finding that Robbins had a reasonable expectation of
                  privacy in his duffelbag and plastic-wrapped packages, the Court also held that the
                  automobile exception to the warrant requirement, see Carroll v. United States, 267
                  U.S. 132, 153 (1925), did not apply to packages found in an automobile. The Court
                  overruled the latter determination in United States v. Ross, 456 U.S. 798 (1982),
                  but reaffirmed that where, as here, the automobile exception is inapplicable, police
                  may not conduct a warrantless search of any container that conceals its contents.
 [ Footnote 2 ] Both to support its position that society recognizes no reasonable
                  privacy interest in sealed, opaque trash bags and to refute the prediction that "society
                  will be shocked to learn" of that conclusion, supra, at 46, the Court relies heavily
                  upon a collection of lower court cases finding no Fourth Amendment bar to trash searches.
                  But the authority that leads the Court to be "distinctly unimpressed" with our position,
                  ante, at 43, n. 5, is itself impressively undistinguished. Of 11 Federal Court of
                  Appeals cases cited by the Court, at least 2 are factually or legally distinguishable,
                  see United States v. O'Bryant, 775 F.2d 1528, 1533-1534 (CA11 1985) (police may search
                  an apparently valuable briefcase "discarded next to an overflowing trash bin on a
                  busy city street"); United States v. Thornton, 241 U.S. App. D.C. 46, 56, 746 F.2d
                  39, 49 (1984) (reasonable federal agents could believe in good faith that a trash
                  search is legal), and 7 rely entirely or almost entirely on an abandonment theory
                  that, as noted infra, at 51, the Court has discredited, see United States v. Dela
                  Espriella, 781 F.2d 1432, 1437 (CA9 1986) ("The question, then, becomes whether placing
                  garbage for collection constitutes abandonment of property"); United States v. Terry,
                  702 F.2d 299, 308-309 (CA2) ("[T]he circumstances in this case clearly evidence abandonment

                  of trash in garbage cans at a time and place for anticipated collection by public
                  employees for hauling to a public dump signifies abandonment"); United States v. Vahalik,
                  606 F.2d 99, 100-101 (CA5 1979) (per curiam) ("[T]he act of placing garbage for collection
                  is an act of abandonment which terminates any fourth amendment protection"), cert.
                  denied, 444 U.S. 1081 (1980); United States v. Crowell, 586 F.2d 1020, 1025 (CA4 1978)
                  ("The act of placing [486 U.S. 35, 50] [garbage] for collection is an act of abandonment
                  and what happens to it thereafter is not within the protection of the fourth amendment"),
                  cert. denied, 440 U.S. 959 (1979); Magda v. Benson, 536 F.2d 111, 112 (CA6 1976) (per
                  curiam) ("[F]ederal case law . . . holds that garbage . . . is abandoned and no longer
                  protected by the Fourth Amendment"); United States v. Mustone, 469 F.2d 970, 972 (CA1
                  1972) (when defendant "deposited the bags on the sidewalk he abandoned them"). A reading
                  of the Court's collection of state-court cases reveals an equally unimpressive pattern.

                  at 43 ("[T]he Fourth Amendment analysis must turn on such factors as `our societal
                  understanding that certain areas deserve the most scrupulous protection from government

 [ Footnote 4 ] To be sure, statutes criminalizing interference with the mails might
                  reinforce the expectation of privacy in mail, see, e. g., 18 U.S.C. 1701-1705, 1708,
                  but the expectation of privacy in no way depends on statutory protection. In fact,
                  none of the cases cited in the text even mention such statutes in finding Fourth Amendment
                  protection in materials handed over to public or private carriers for delivery. [486
