OPINION

WRIGHT, Justice.

In this case, we consider whether there is a principled basis for interpreting Article I, Section 10, of the Minnesota Constitution to require greater protection than the Fourth Amendment to the United States Constitution in the context of a warrantless search of garbage set out for collection in an area accessible to the public. Applying the principles articulated in Kahn v. Griffin, 701 N.W.2d 815 (Minn. 2005), to the facts of this case, we do not have a "clear and strong conviction" that there is a principled basis for interpreting Article I, Section 10, of the Minnesota Constitution to require greater protection than the Fourth Amendment to the United States Constitution. We therefore affirm.

On January 25, 2012, a mandated reporter informed the Hutchinson police that appellant David Ford McMurray's daughter saw her mother with "a pipe believed to be used for drugs." Officer Erlandson, an investigator with Hutchinson Police Services and a member of the Southwest Metro Drug Task Force, checked police records and learned that both McMurray and his wife previously had been arrested for controlled substance violations.

Officer Erlandson contacted the commercial truck driver who collects McMurray's garbage and sought the driver's assistance in securing the garbage that McMurray placed at the curb for collection. On February 2, 2012, Officer Erlandson observed the driver pick up the garbage from the curb outside McMurray's home and immediately thereafter met the driver in a predetermined location to retrieve the garbage. When Officer Erlandson searched the garbage, he found several plastic bags containing white residue, which later tested positive as methamphetamine. The garbage also contained drug paraphernalia and documents belonging to McMurray and his wife.

The next day, based on the information police received from the mandated reporter and the warrantless search of McMurray's garbage, Officer Erlandson obtained a warrant to search McMurray's home. Police executed the search warrant and found McMurray with two other people in an upstairs bedroom. While searching the bedroom, police found, inside a clothes basket, plastic bags containing a "crystal like substance" and a letter addressed to McMurray. A laboratory test confirmed that one of the plastic bags contained 3.3 grams of methamphetamine.

McMurray was charged with third-degree possession of a controlled substance. Minn.Stat. § 152.023, subds. 2(a)(1), 3(b) (2014). McMurray moved to suppress the evidence seized from his home. In support of the motion to suppress, McMurray argued that the warrantless search of his garbage violated Article I, Section 10, of the Minnesota Constitution, which provides, "The right of the people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures shall not be violated; and no warrant shall issue but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched and the person or things to be seized." He further argued that without the evidence found in his garbage, the application for a warrant to search his home was not supported by probable cause, and that the search of his home was, therefore, unconstitutional. The State urged the district court to deny the suppression motion, citing State v. Oquist, 327 N.W.2d 587, 591 (Minn.1982), in which we held "the defendant had no reasonable expectation of privacy with respect to the contents of the plastic bags placed in or near his open garbage can" when the contents were examined "without trespassing on the defendant's premises." The district court denied the motion to suppress, concluding that Oquist was controlling.

McMurray waived his right to a jury trial and submitted his case to the district court on stipulated facts under Minn. R.Crim. P.26.01, subd. 3. The district court found McMurray guilty of third-degree possession of a controlled substance and imposed a 24-month sentence, which is the mandatory minimum sentence for a person previously convicted of a felony controlled substance crime. See Minn.Stat. § 152.023, subd. 3(b).

McMurray appealed to the court of appeals, arguing among other grounds that the district court committed reversible error by denying his motion to suppress. The court of appeals affirmed, stating that "[f]ollowing United States Supreme Court precedent, Minnesota courts have consistently held that garbage left on a curb or adjacent to an alley that is seized in a routine curbside pickup does not constitute an illegal search." State v. McMurray, No. A12-2266, 2013 WL 5021206, at *2 (Minn.App. Sept. 16, 2013).

We granted McMurray's petition for further review on the issue of whether Article I, Section 10, of the Minnesota Constitution requires greater protection than the Fourth Amendment to the United States Constitution in the context of a warrantless search of garbage set out for collection in an area accessible to the public.

I.

In California v. Greenwood, 486 U.S. 35, 108 S.Ct. 1625, 100 L.Ed.2d 30 (1988), the United States Supreme Court concluded that an individual does not have a reasonable expectation of privacy in garbage left at the curb. Id. at 39-41, 108 S.Ct. 1625. Consequently, a warrantless search of such garbage does not violate the Fourth Amendment to the United States Constitution. Id. Acknowledging Greenwood, McMurray concedes that the Fourth Amendment does not prohibit warrantless searches of garbage set out for collection. Despite the fact that the language of Article I, Section 10, of the Minnesota Constitution is substantially similar to the language of the Fourth Amendment,1 McMurray asks us to interpret Article I, Section 10, to provide greater protection than the Fourth Amendment because in his view the United States Supreme Court's reasoning in Greenwood is not persuasive.2 To support his argument, McMurray relies heavily on the Greenwood dissent and the decisions of a minority of other state courts.3

As a separate source of rights, the Minnesota Constitution may under certain circumstances provide greater protection than the United States Constitution. Kahn, 701 N.W.2d at 823-24. Yet when independently interpreting the Minnesota Constitution, we will not reject a United States Supreme Court interpretation of identical or substantially similar language "merely because one prefers the opposite result." Women of the State of Minn. by Doe v. Gomez, 542 N.W.2d 17, 30 (Minn. 1995). Our precedent establishes that we approach the responsibility of interpreting identical or substantially similar language with restraint. Kahn, 701 N.W.2d at 828. As we follow the general principle of "favoring uniformity" with the United States Constitution, we decline to "lightly reject" a United States Supreme Court interpretation of "identical or substantially similar language." Id. at 824. Rather, when a federal constitutional provision has the same or substantially similar language and the United States Supreme Court has interpreted that language, we will not construe the Minnesota Constitution as granting greater protection for individual rights "unless there is a principled basis to do so." Id. (citing State v. Harris, 590 N.W.2d 90, 97-98 (Minn.1999)).

In Kahn, we identified a nonexclusive list of factors that may be considered in determining whether there is a principled basis for interpreting the Minnesota Constitution to provide greater protection than the United States Constitution:

Id. at 829. When the text of our state constitution is materially identical to the federal constitution, as it is here, we have construed the Minnesota Constitution to provide greater protection than the United States Constitution: (1) when the United States Supreme Court "`has made a sharp or radical departure from its previous decisions' and we `discern no persuasive reason to follow such a departure'"; (2) when the Court has "retrenched on a Bill of Rights issue"; or (3) when the Court precedent "`does not adequately protect our citizens' basic rights and liberties.'" Rew v. Bergstrom, 845 N.W.2d 764, 795 (Minn.2014) (quoting Kahn, 701 N.W.2d at 828).

In light of the well-established principles articulated in Kahn, the issue presented in this case is not whether the reasoning of the Supreme Court in Greenwood is persuasive. Rather, the issue is whether we have a "clear and strong conviction" that there is a "principled basis" for us to interpret Article I, Section 10, of the Minnesota Constitution to provide greater protection from warrantless searches of garbage set out for collection than the Fourth Amendment to the United States Constitution. We therefore consider whether the legal issue in this case presents one of the three situations articulated in Kahn, 701 N.W.2d at 828.

We first consider whether the United States Supreme Court's decision in Greenwood marked a sharp or radical departure from its Fourth Amendment precedent. At the time of Greenwood's appeal, the United States Supreme Court's Fourth Amendment precedent had established the following two principles. First, a person could invoke the protections of the Fourth Amendment if the person had a reasonable expectation of privacy in the area or items searched. Katz v. United States, 389 U.S. 347, 360, 88 S.Ct. 507, 19 L.Ed.2d 576 (1967) (Harlan, J., concurring).4 Second, what a person knowingly exposed to the public, even in the person's own home or office, was not a subject of Fourth Amendment protection. California v. Ciraolo, 476 U.S. 207, 213, 106 S.Ct. 1809, 90 L.Ed.2d 210 (1986) (quoting Katz, 389 U.S. at 351, 88 S.Ct. 507). Applying these two principles to the facts in Greenwood, the United States Supreme Court concluded that a warrantless search of garbage is permitted under the Fourth Amendment because a person has no reasonable expectation of privacy in garbage set out for collection. 486 U.S. at 40-41, 108 S.Ct. 1625. The Greenwood Court reasoned that it is common knowledge that members of the public rummage through plastic garbage bags placed at the side of a public street. Id. at 40, 108 S.Ct. 1625. Furthermore, garbage is placed at the curb with the expectation that a third-party trash collector will take it, and the trash collector could sort through the garbage or permit others to do so. Id. The Greenwood Court concluded that it is not reasonable to expect the contents of garbage bags placed on the side of a public street for collection to remain private. Id. at 40-41, 108 S.Ct. 1625. Therefore, garbage bags placed at curbside for collection are out-side the scope of Fourth Amendment protections and may be searched without a warrant and without reasonable suspicion of criminal activity.

Based on our review of the Greenwood decision, we conclude that it did not constitute a "sharp or radical departure" from the United States Supreme Court's previous approach to the law. See Kahn, 701 N.W.2d at 828. Rather, it simply applied the principles previously articulated in Katz and Ciraolo in a slightly different context. Moreover, the analysis adopted in Greenwood was consistent with the decisions of a vast majority of state courts, including our decision applying the Fourth Amendment in State v. Oquist, 327 N.W.2d 587, 591 (Minn.1982).

We next consider whether the United States Supreme Court's decision in Greenwood retrenched on a Bill of Rights issue. The relevant inquiry regarding retrenchment is not whether the United States Supreme Court has retrenched on Bill of Rights issues generally but whether it has retrenched on the specific Bill of Rights issue at hand — here, protection against warrantless searches.5 See, e.g., Rew, 845 N.W.2d at 795 (interpreting the question of retrenchment as referring only to the specific Bill of Rights issue at hand). We conclude that the Greenwood decision did not retrench on the protection against warrantless searches. Far from retrenching on the existing protections against warrantless searches, the analysis adopted in Greenwood was consistent with the decisions of a vast majority of state courts, including our decision in Oquist, 327 N.W.2d at 591. Moreover, McMurray has not identified any court or commentator that has described Greenwood as a "retrenchment" on the protections against warrantless searches.6

Finally, we consider whether the Greenwood rule permitting warrantless searches of garbage set out for collection fails to adequately protect a basic right or liberty of the citizens of Minnesota. See Kahn, 701 N.W.2d at 828. This inquiry requires more than a conviction that we would have decided the issue differently in the first instance. See State v. Wiegand, 645 N.W.2d 125, 133 n. 8 (Minn.2002) (refusing to interpret the Minnesota Constitution more broadly than the United States Constitution with regard to dog sniffs and stating that "we do not resort to the Minnesota Constitution whenever we simply would have decided the matter differently"). Instead, our inquiry considers whether there is a "unique, distinct, or peculiar issue[] of state and local concern" that requires protection. Kahn, 701 N.W.2d at 829. For example, in Friedman v. Commissioner of Public Safety, this court observed that "Minnesota has a long tradition of assuring the right to counsel." 473 N.W.2d 828, 831 (Minn. 1991). In light of this tradition, inter alia, we held in Friedman that the Minnesota Constitution gives a motorist a limited right to consult an attorney before deciding whether to submit to chemical testing for blood alcohol. Id. at 835.

Unlike the traditional protection of the right to counsel recognized in Friedman, Minnesota does not have a long tradition of protecting garbage set out for collection from a warrantless search. Instead, during the last 32 years, we have repeatedly held that garbage set out for collection is not protected by the Fourth Amendment and may be searched without a warrant. See State v. Dreyer, 345 N.W.2d 249, 250 (Minn.1984); Oquist, 327 N.W.2d at 591; see also State v. Krech, 403 N.W.2d 634, 636 (Minn.1987) (stating that garbage placed in a dumpster at a duplex was "abandoned property in which defendant no longer had a reasonable expectation of privacy"); cf. State v. Goebel, 654 N.W.2d 700, 703-04 (Minn.App.2002).

In sum, we conclude that Greenwood was not a sharp or radical departure from United States Supreme Court precedent, did not retrench on a Bill of Rights issue, and does not fail to adequately protect a unique, distinct, or peculiar issue of state and local concern. We therefore conclude there is no principled basis for us to interpret Article I, Section 10, of the Minnesota Constitution to require greater protection than the Fourth Amendment to the United States Constitution in the context of a warrantless search of garbage set out for collection in an area accessible to the public.

II.

The dissent would interpret Article I, Section 10, to require greater protection than the Fourth Amendment for three reasons. First, the dissent is persuaded by the arguments put forward by Justice Brennan in his dissent in Greenwood. Second, the dissent contends that changes in the content of garbage and in city ordinances relating to garbage disposal and container design have strengthened the expectation of privacy with respect to garbage. Third, a number of other state courts have interpreted their state constitutions to provide greater protection than the Fourth Amendment to the United States Constitution in the context of a warrantless search of garbage set out for collection in an area accessible to the public. For the reasons that follow, we are not persuaded by the dissent's analysis.

In his Greenwood dissent, Justice Brennan argued that all Americans retain a reasonable expectation of privacy in garbage set out for collection because "[a] single bag of trash testifies eloquently to the eating, reading and recreational habits of the person who produced it." 486 U.S. at 50, 108 S.Ct. 1625 (Brennan, J., dissenting). He equated a search of trash with a search of a bedroom or desk drawers because it "can relate intimate details about sexual practices, health, and personal hygiene" as well as a person's "financial and professional status, political affiliations and inclinations, private thoughts, personal relationships, and romantic interests." Id. Justice Brennan also emphasized:

Id. at 52, 108 S.Ct. 1625 (alteration in original) (quoting United States v. Dzialak, 441 F.2d 212, 215 (2d Cir.1971)). He further emphasized that many "county ordinance[s] command[]" that a person set his or her garbage out on the curb, and therefore the act of placing garbage on the curb does not "amount to a relinquishment of a privacy expectation in it." Id. at 54-55, 108 S.Ct. 1625.

The dissent's analysis mirrors Justice Brennan's analysis. For example, the dissent contends that "[h]ousehold waste contains a great deal of personal information that most of us expect will remain private." Infra at 697. The dissent also contends that municipal ordinances that prohibit the scavenging of recyclable materials and regulate the collection of garbage support the reasonableness of an expectation that household garbage will remain private from unwarranted inspection by the government. Infra at 698-99. In effect, the dissent contends that Article I, Section 10, of the Minnesota Constitution should be interpreted to require greater protection than the Fourth Amendment because it finds the arguments of the dissent in Greenwood to be persuasive. However, under the well-established principles articulated in Kahn, we do not construe the Minnesota Constitution to provide greater protection "merely because we want to bring about a different result." Kahn, 701 N.W.2d at 824.

The dissent next argues that today's garbage is "not your grandfather's garbage" because "[v]astly more household waste is being recycled" and garbage "may now contain digital material such as disks, chips, and flash drives." Infra at 697-98. Because the introduction of digital media has been accompanied by corresponding changes in the way we dispose of sensitive items and information,7 we are unpersuaded by the dissent's argument. If, as the dissent contends, the nature of household waste has changed, as well as the "dented metal garbage cans" that were once set out at the curb, infra at 699, so too have Minnesotans' disposal habits. A misplaced bank statement, an improperly discarded hard drive, or poor judgment when interacting with others via social media leaves an individual vulnerable to consequences ranging from embarrassment to identity theft and fraud. We do not minimize that certain negative consequences have arisen from technological developments, but we also consider the practical reality when determining whether changed circumstances justify a change in the law. Minnesotans are well aware of potential threats to their privacy and security and have prudently altered their conduct in response.

Finally, the dissent cites to a handful of state supreme courts, each relying on its state constitution, that have concluded that people have a reasonable expectation of privacy in the garbage they set out for collection. See, e.g., State v. Goss, 150 N.H. 46, 834 A.2d 316 (2003); State v. Hempele, 120 N.J. 182, 576 A.2d 793 (1990); State v. Morris, 165 Vt. 111, 680 A.2d 90 (1996). But the courts of New Hampshire, New Jersey, and Vermont have not, as we have, determined that they will depart from Fourth Amendment precedent only in the limited situations that are not present here. See Kahn, 701 N.W.2d at 825 ("Generally, we do not independently apply our state constitution absent language, concerns, and traditions unique to Minnesota.") To the contrary, the Morris court emphasized its freedom to depart from Supreme Court precedent: "We are a sovereign state, and this Court is entitled to take issue with any constitutional decision of the United States Supreme Court, regardless of whether our constitution provides the same or a different text." Morris, 680 A.2d at 101 (emphasis added). Because the courts in Goss, Hempele, and Morris were not constrained by the principles articulated in Kahn, 701 N.W.2d at 824, the dissent's reliance on those cases is misplaced.

III.

Having concluded there is no principled basis to interpret Article I, Section 10, of the Minnesota Constitution to afford greater protection against warrantless searches of garbage set out for collection than the Fourth Amendment to the United States Constitution, we review the search of McMurray's garbage in accordance with Greenwood, 486 U.S. 35, 108 S.Ct. 1625, and Oquist, 327 N.W.2d 587. Under Greenwood and Oquist, a person has no reasonable expectation of privacy in garbage set out for collection on the side of a public street because such garbage is readily accessible to scavengers and other members of the public. Here, McMurray left the garbage at the curb outside his home with the expectation that the garbage collector would take it. Any member of the public could have accessed McMurray's garbage without trespassing on his property, and police do not need a warrant to search items that are exposed to the public.8 Because a police officer could have taken the garbage from the curb directly, it was lawful for Officer Erlandson to obtain McMurray's garbage from the garbage collector. The warrantless search of McMurray's garbage, therefore, was reasonable under both the Fourth Amendment to the United States Constitution and Article I, Section 10, of the Minnesota Constitution. Because we conclude that the search of McMurray's garbage was reasonable under the state and federal constitutions, the search warrant for McMurray's residence that police subsequently obtained based on evidence found in the garbage was valid. Therefore, the district court properly denied McMurray's motion to suppress evidence collected during the search of his residence.

Affirmed.

ANDERSON, J., took no part in the consideration or decision of this case.

LILLEHAUG, Justice (dissenting).

Minnesotans have a reasonable expectation of privacy when they put their household waste in opaque bags and do what the government requires: place the bags in closed containers for collection, compaction, and conveyance to a lawful disposal site. I respectfully disagree with the majority that the Minnesota Constitution does not require a search warrant before law enforcement may seize and search such household waste.

I.

On Thursday, February 2, 2012, David McMurray did what most residents of his Hutchinson neighborhood do on a Thursday: he moved his garbage container to the curb for pick-up. Like most everyone else on that Thursday, McMurray placed opaque bags containing household waste in a container that complied with a municipal ordinance: a "clean, rust-resistant, water-tight, non-absorbent and washable closed container[], approved for the purpose by the city." Hutchinson, Minn., Code of Ordinances § 51.03 (2013). In Hutchinson, that closed container was furnished by Waste Management, the city franchisee.

Every week the Waste Management driver would take McMurray's bags from the closed container at the curb, throw the bags into the truck, compact the bags with the neighbors' garbage, and deposit the compacted household waste in the local landfill. But Thursday, February 2, was different. Based on a tip, a Hutchinson police officer called the driver and arranged for McMurray's bags to receive special treatment. The officer directed that, rather than being thrown in the truck, compacted with the neighbors' bags, and taken to the landfill, McMurray's bags be set aside for a special law enforcement inspection.

Not surprisingly, the city's franchisee did as told. Shortly after picking up and segregating McMurray's bags, Waste Management delivered them to the officer, who took them to the police station. Opening the bags, the officer sifted through the household waste and found evidence of illegal narcotics. The officer used that evidence as probable cause for a warrant to search McMurray's residence. That search led to McMurray being charged with a third-degree controlled substance violation.

In the district court, McMurray moved to suppress the narcotics evidence on the ground that the warrantless seizure and search of his bags was unconstitutional. The district court denied the motion and convicted McMurray on stipulated facts. The court of appeals affirmed the conviction. State v. McMurray, No. A12-2266, 2013 WL 5021206 (Minn.App. Sept. 16, 2013). We granted review to decide whether, under the Minnesota Constitution, a citizen has a reasonable expectation of privacy in the contents of bags containing household waste placed in a closed container set out at the curb for lawful collection.

II.

McMurray acknowledges that the issue presented in this case has already been decided under the Fourth Amendment. The U.S. Supreme Court has held that there is no reasonable expectation of privacy in garbage placed at the curb for collection. California v. Greenwood, 486 U.S. 35, 39-41, 108 S.Ct. 1625, 100 L.Ed.2d 30 (1988).

Instead, McMurray invokes Article I, Section 10 of the Minnesota Constitution ("Section 10"), which contains a warrant requirement almost identical to the Fourth Amendment's. Despite the similarity in wording, "[i]t is axiomatic that we are free to interpret the Minnesota Constitution as affording greater protection against unreasonable searches and seizures than the United States Constitution." State v. Askerooth, 681 N.W.2d 353, 361 (Minn.2004). And we have done so. See id. at 363 (search or seizure during traffic stop must be reasonable even when a minor law has been violated). See also State v. Davis, 732 N.W.2d 173, 181 (Minn.2007) (dog sniff in hallway outside apartment constitutes a search requiring a reasonable articulable suspicion of criminal activity); State v. Carter, 697 N.W.2d 199, 212 (Minn.2005) (dog sniff of an area outside storage unit was an unreasonable search under Section 10 when officers lacked a reasonable articulable suspicion of criminal activity); State v. Fort, 660 N.W.2d 415, 419 (Minn.2003) (search of a passenger stopped for routine traffic violations exceeded the scope of a traffic stop); In re Welfare of B.R.K., 658 N.W.2d 565, 577-78 (Minn.2003) (legitimate expectation of privacy under Section 10 for short-term social guests, even if not under Fourth Amendment); Ascher v. Comm'r of Pub. Safety, 519 N.W.2d 183, 187 (Minn.1994) (temporary roadblocks to stop cars without objective, individualized articulable suspicion violate Section 10); In re Welfare of E.D.J., 502 N.W.2d 779, 783 (Minn.1993) (under Section 10, a person is "seized" when he reasonably concludes that he is not free to leave). But we have never applied Section 10 to the question presented today.

The majority is correct that we must not "lightly" interpret and apply Section 10 in a manner different than the Fourth Amendment. The majority is also correct that we may do so if we have a clear and strong conviction that there is a principled basis for so doing, State v. Carter, 596 N.W.2d 654, 657 (Minn.1999). See Kahn v. Griffin, 701 N.W.2d 815, 828 (Minn.2005).

As the majority states, under Kahn v. Griffin, we will consider a departure from U.S. Supreme Court precedent under any of three conditions. 701 N.W.2d at 828. In my view, this case implicates the third condition: whether a U.S. Supreme Court holding (here, in California v. Greenwood) adequately protects Minnesotans' basic rights and liberties. I have a clear and strong conviction that it does not. Our basic rights and liberties are at risk if government can seize and search Minnesotans' household waste without a search warrant and, apparently, without even a reasonable articulable suspicion of wrongdoing.

III.

Under both the U.S. Constitution and the Minnesota Constitution, warrantless searches in circumstances in which an individual has a reasonable expectation of privacy "are per se unreasonable ... subject only to a few specifically established and well-delineated exceptions." Katz v. United States, 389 U.S. 347, 357, 88 S.Ct. 507, 19 L.Ed.2d 576 (1967); In re Welfare of D.A.G., 484 N.W.2d 787, 789 (Minn.1992).

Prior to Greenwood, we recognized "that a householder may ordinarily have some expectation of privacy in the items he places in his garbage can." State v. Oquist, 327 N.W.2d 587, 591 (Minn.1982) (noting that expectation but concluding that there was no such expectation when household waste was seized at the curb). Household waste contains a great deal of personal information that most of us expect will remain private. As the New Jersey Supreme Court put it, "Clues to people's most private traits and affairs can be found in their garbage." State v. Hempele, 120 N.J. 182, 576 A.2d 793, 802 (1990). One who examines garbage carefully can learn about the household members' physical and mental health, sexual activities, financial status, consumer preferences, political affiliations, and personal relationships. See id. at 802-03; see also State v. Tanaka, 67 Haw. 658, 701 P.2d 1274, 1276-77 (1985). At different times, people dispose of drug bottles, birth control devices, sanitary products, printouts of emails, check registers, photos, and whatever they have recently read or eaten. It is the very privacy — the intimacy — of this personal information that makes it of great interest to others, ranging from law enforcement officers to private investigators to neighborhood snoops. Until a person's garbage "`ha[s] lost its identity and meaning by becoming part of a large conglomeration of trash elsewhere,'" we "`can readily ascribe many reasons why residents would not want their ... telltale refuse and trash to be examined by neighbors or others.'" People v. Krivda, 5 Cal.3d 357, 96 Cal.Rptr. 62, 486 P.2d 1262, 1268 (1971) (emphasis omitted) ((quoting People v. Edwards, 71 Cal.2d 1096, 80 Cal.Rptr. 633, 458 P.2d 713, 718) (1969)), vacated, 409 U.S. 33, 93 S.Ct. 32, 34 L.Ed.2d 45 (1972), remanded to 8 Cal.3d 623, 105 Cal.Rptr. 521, 504 P.2d 457 (1973) (reaffirming original decision under the California Constitution).

Since the 1980s, when Oquist and Greenwood were decided, the nature of household waste has changed. This is not your grandfather's garbage. Vastly more household waste is being recycled and the digital revolution is in full flourish. For good public policy reasons, government encourages and often requires citizens to segregate and set out or deliver for recycling digital devices such as obsolete or broken servers, routers, tablets, and cell phones. And waste disposal bags and containers may now contain digital material such as disks, chips, and flash drives. As the U.S. Supreme Court has recently and aptly recognized, digital devices and media, "[w]ith all they contain and all they may reveal, ... hold for many Americans `the privacies of life.'" Riley v. California, ___ U.S. ___, 134 S.Ct. 2473, 2494-95, 189 L.Ed.2d 430 (2014) (citation omitted). This trend will only accelerate as we enter the "internet of things" in which hundreds of billions of objects will become digital devices. See generally Scott R. Peppet, Regulating the Internet of Things: First Steps Toward Managing Discrimination, Privacy, Security, and Consent, 93 Tex. L. Rev. 85, 89 (2014).

Not only has the nature of household waste changed, so has government's ability to analyze it. Investigative tools are much more sophisticated and their probing capacity now extends well beyond the curtilage. For example, law enforcement now has the ability to test — easily and economically — the DNA that can be gleaned from all manner of waste. The biological detritus of our existence inevitably ends up in household waste — on items such as used tissues and sanitary products, partially eaten food, discarded contact lenses, and things that we've simply touched — and there is little that people can do to avoid this, short of illegally burning or chemically treating every item. See Hempele, 576 A.2d at 808. For most people, maintaining the privacy of their household waste by burying it on the back forty is no longer a viable option.

What has not changed, and what should not change, is the long-standing presumption that a search warrant is required to search a Minnesotan's container. A container is "any object capable of holding another object," including "luggage, boxes, bags, clothing, and the like." New York v. Belton, 453 U.S. 454, 460-61 n. 4, 101 S.Ct. 2860, 69 L.Ed.2d 768 (1981). The bags that hold household waste and the bins in which they must be placed are simply forms of containers. Typically, in the absence of an exception such as exigency or search incident to arrest, we require that the State obtain a warrant before it opens a Minnesotan's container. "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, 104 S.Ct. 1652, 80 L.Ed.2d 85 (1984). "As for the contents of a container, the mere fact that the container itself is in plain view provides no basis for a warrantless seizure and search of it, even assuming probable cause as to the contents." In re Welfare of G.M., 560 N.W.2d 687, 694 (Minn.1997) (quoting 1 Wayne R. LaFave, Search and Seizure § 2.2(a), at 401-02 (3d ed.1996)) (but holding that warrantless search of a closed pouch on the suspect's person was justified under the search incident to arrest exception). McMurray's opaque bags and the closed receptacle in which they were placed were containers that should not have been seized and searched without a warrant.

But, holds the majority, based on Greenwood and our earlier Fourth Amendment cases, a citizen's reasonable expectation of privacy in household waste is lost when the waste is set out for collection in an area accessible to the public. As Greenwood put it: "It is common knowledge that plastic garbage bags left on or at the side of a public street are readily accessible to animals, children, scavengers, snoops, and other members of the public," as well as to the waste disposal company. 486 U.S. at 40, 108 S.Ct. 1625 (footnotes omitted).

With all respect to the majorities in Greenwood and here, it has always struck me as odd that, because raccoons, squirrels, and their nosy human counterparts try to get into household waste containers and sometimes succeed, that should somehow determine the reasonableness of our expectations of privacy. That concept is as outdated as the dented metal garbage cans with partially open lids and visible garbage that I remember from childhood. Not only is household waste different than it was when Greenwood was decided, so are the bags and special containers into which the waste is placed for pickup or recycling. Like the City of Hutchinson, many municipalities now require closed, vermin-proof containers.1

The golden age of human scavenging, too, has passed. While most garbage containers set out for collection are not locked, and dumpster diving may still occur, government now recognizes that homeowners and renters have a legitimate expectation that the household waste they set out for disposal or recycling will not be strewn about or diverted but will be conveyed directly for reuse, burning, or interment. Minneapolis and Duluth, for example, prohibit turning over or upsetting the contents of any waste container,2 and most municipalities have laws against littering. Minneapolis provides that "no persons other than those authorized by the city engineer shall remove any solid waste [from a container], except with the consent of the owner or occupant of the property served." Minneapolis, Minn., Code of Ordinances § 225.590 (2014). Saint Paul, Bloomington, Duluth, Brooklyn Park, Plymouth, Saint Cloud, Moorhead, and other cities prohibit scavenging of recyclable materials.3 I agree with the New Mexico Supreme Court, which said recently, "We consider compliance with local ordinances governing the disposal of household garbage to support the reasonableness of an expectation that it will remain private from unwarranted inspection by the government." State v. Crane, ___ N.M. ___, 329 P.3d 689, 696-97 (2014) (Vigil, C.J.).

While a number of state supreme courts have followed Greenwood and held that there is no reasonable expectation of privacy in household waste set out for collection,4 others have recognized such an expectation, and have required a warrant,5 or at least a reasonable articulable suspicion,6 for seizure and search. Having reviewed the arguments set forth in these cases, I have a definite and firm conviction that the better view is that a warrant is required.

IV.

The majority holds that, under the Minnesota Constitution, Minnesotans have no expectation of privacy in household waste at the curb, that the officer's seizure and search was "lawful," and that, essentially, household privacy ends at the sidewalks. Yet, while the question of whether at least a reasonable articulable suspicion is required for the seizure of household waste was fully briefed by the parties, the majority opinion "[p]rudently" decides not to answer that question. I would like to think that the question remains open, but the issue before us is the constitutional standard for the seizure and search of household waste. Rather than declaring the search "lawful," the majority should have made clear that a warrantless seizure and search is not lawful without at least a reasonable articulable suspicion.

The diversion and inspection of household waste is more intrusive than investigative activities we have held require a reasonable articulable suspicion, such as dog sniffs in apartment hallways or outside storage units. See State v. Davis, 732 N.W.2d 173, 181 (Minn.2007); State v. Carter, 697 N.W.2d 199, 211-12 (Minn.2005). In Carter, we highlighted "the capability of the [storage] unit, like a residence, to store a significant amount of personal items and be the site of personal activity." State v. Eichers, 853 N.W.2d 114, 126 (Minn.2014) (citing Carter, 697 N.W.2d at 210-11). By contrast, we determined in Eichers that "[a] mailed package does not give rise to the same concerns regarding personal activity, and the number of personal items a package can contain is significantly lower." Id. In effect, "[a] residence or storage unit is a window into a person's life in a way that a mailed package is not." Id.

Household waste from a residence is far more analogous to the odors from a hallway or storage unit than to those from a mailed package, as household waste is a window into "people's most private traits" and activities. State v. Hempele, 120 N.J. 182, 576 A.2d 793, 802 (1990). And people have less choice about what they must put out for waste disposal than what they put in a storage unit or in a mailed package.

If Minnesotans' household privacy ends at their sidewalks, there would be nothing unconstitutional about a government program to seize and perform a forensic inspection of the waste from every Minnesota household, all without the barest suspicion. Nor would it be unconstitutional for government agencies to scan and copy the data on all digital devices Minnesotans turn in for recycling. Of course, I am not aware that any such programs are contemplated. But, in an age in which government can surreptitiously gather almost every call and email,7 it is not in the realm of fantasy to expect that, soon, government agencies will have the motivation and the technology to do so. This case would have been a good opportunity to make clear that, in the absence of reasonable articulable suspicion, government does not have a green light to broaden and deepen its efforts to acquire our most intimate information.

V.

In this case we should have said, as the United States Supreme Court said about cellphone searches: "Our answer to the question of what police must do before searching [Minnesotans' household waste is] simple — get a warrant." See Riley, ___ U.S. at ___, 134 S.Ct. at 2495.

For all of these reasons, I respectfully dissent.
