    In 2004, California voters passed Proposition 69 (Prop. 69, as approved by
    voters, Gen. Elec. (Nov. 2, 2004); known as the “DNA Fingerprint, Unsolved
    Crime and Innocence Protection Act” (DNA Act)) to expand existing requirements
    for the collection of DNA identification information for law enforcement
    purposes. The DNA Act requires law enforcement officials to collect DNA
    samples, as well as fingerprints, from all persons who are arrested for, as well as
    those who have been convicted of, felony offenses. (Pen. Code, § 296.1, subd.
    (a)(1)(A).)
    Defendant Mark Buza was arrested for arson and related felonies and
    transported to jail. At booking, a jail official informed defendant that he was
    required to provide a DNA sample by swabbing the inside of his cheek. He
    refused. A jury later convicted him of both the arson-related felonies and the
    misdemeanor offense of refusing to provide a specimen required by the DNA Act.
    (Pen. Code, § 298.1, subd. (a).)
    SEE DISSENTING OPINIONS
    The Court of Appeal reversed defendant’s misdemeanor refusal conviction,
    holding that the DNA Act violated defendant’s rights under the Fourth
    Amendment to the United States Constitution. While the case was pending on
    appeal, the United States Supreme Court addressed a similar issue in Maryland v.
    King (2013) 
    569 U.S. 435
    (King), and reached a different conclusion. The high
    court held that “[w]hen officers make an arrest supported by probable cause to
    hold for a serious offense and they bring the suspect to the station to be detained in
    custody, taking and analyzing a cheek swab of the arrestee’s DNA is, like
    fingerprinting and photographing, a legitimate police booking procedure that is
    reasonable under the Fourth Amendment.” (Id. at pp. 465–466.)
    Following the high court’s decision in King, this case returned to the Court
    of Appeal. On remand, the Court of Appeal again reversed defendant’s
    misdemeanor refusal conviction, this time on the ground that the DNA Act
    violates the California Constitution’s prohibition on unreasonable searches and
    seizures. (Cal. Const., art. I, § 13.)
    Defendant raises a number of questions about the constitutionality of the
    DNA Act as it applies to various classes of felony arrestees. But the question
    before us is a narrower one: Whether the statute’s DNA collection requirement is
    valid as applied to an individual who, like defendant, was validly arrested on
    “probable cause to hold for a serious offense”—here, the felony arson charge for
    which defendant was ultimately convicted—and who was required to swab his
    cheek as “part of a routine booking procedure” at county jail. 
    (King, supra
    , 569
    U.S. at p. 465.) Under the circumstances before us, we conclude the requirement
    is valid under both the federal and state Constitutions, and we express no view on
    the constitutionality of the DNA Act as it applies to other classes of arrestees. We
    accordingly reverse the judgment of the Court of Appeal in this case.
    2
    I.
    A.
    For decades before the DNA Act, California law had required the collection
    of biological samples from individuals convicted of certain offenses. In 1983, the
    Legislature enacted legislation requiring certain sex offenders to provide blood
    and saliva samples before their release or discharge. (Stats. 1983, ch. 700, § 1,
    pp. 2680–2681, codified at Pen. Code, former § 290.2.) In 1998, the Legislature
    enacted the “DNA and Forensic Identification Data Base and Data Bank Act,”
    which required the collection of DNA samples from persons convicted of certain
    felony offenses, including certain sex offenses, homicide offenses, kidnapping,
    and felony assault or battery. (Stats. 1998, ch. 696, § 2, pp. 4574–4579; Pen.
    Code, former § 296, subd. (a).)
    When the California electorate voted to pass Proposition 69 on the 2004
    general election ballot, it substantially expanded the scope of DNA sampling to
    include individuals who are arrested for any felony offense, as well as those who
    have been convicted of such an offense. In People v. Robinson (2010) 
    47 Cal. 4th 1104
    (Robinson), this court upheld the expanded DNA collection requirement as
    applied to persons convicted of felony offenses. The question now before us
    concerns the application of the DNA Act to persons who have been arrested for,
    but not yet convicted of, a felony offense.
    In its statutory findings and declarations of purpose, Proposition 69
    explained that expansion of the DNA databank program was warranted to serve a
    “critical and urgent need to provide law enforcement officers and agencies with
    the latest scientific technology available for accurately and expeditiously
    identifying, apprehending, arresting, and convicting criminal offenders and
    exonerating persons wrongly suspected or accused of crime.” (Prop. 
    69, supra
    ,
    3
    § II, subd. (b).) With respect to arrestees in particular, Proposition 69 declared:
    “The state has a compelling interest in the accurate identification of criminal
    offenders”; that “DNA testing at the earliest stages of criminal proceedings for
    felony offenses will help thwart criminal perpetrators from concealing their
    identities and thus prevent time-consuming and expensive investigations of
    innocent persons”; and “it is reasonable to expect qualifying offenders to provide
    forensic DNA samples for the limited identification purposes set forth in this
    chapter.” (Id., § II, subds. (e), (f).)
    The DNA Act provides that, as of January 1, 2009, all adult felony arrestees
    “shall provide buccal swab samples, right thumbprints, and a full palm print
    impression of each hand, and any blood specimens or other biological samples
    required pursuant to this chapter for law enforcement identification analysis.”
    (Pen. Code, § 296, subd. (a).) Providing a buccal swab sample requires the
    arrestee to apply a swab to the inside of his or her cheek to collect the “inner cheek
    cells of the mouth,” which contain DNA. (Id., § 295, subd. (e).) The statute
    provides that these specimens, samples, and print impressions shall be collected
    “immediately following arrest, or during the booking . . . process or as soon as
    administratively practicable . . . but, in any case, prior to release on bail or pending
    trial or any physical release from confinement or custody.” (Id., § 296.1, subd.
    (a)(1)(A).) Refusal to provide any of the required specimens is punishable as a
    misdemeanor. (Id., § 298.1, subd. (a).)
    Collected DNA samples are sent to California Department of Justice’s
    DNA Laboratory for forensic analysis. (Pen. Code, §§ 295, subds. (f), (g),
    (i)(1)(C), 295.1, subd. (c).) The laboratory uses the samples to create a unique
    DNA identification profile, using genetic loci that are known as “junk” or
    “noncoding” DNA, because the loci have no known association with any genetic
    trait, disease, or predisposition. (See 
    King, supra
    , 569 U.S. at pp. 442–443, 445.)
    4
    This profile is stored in California’s DNA databank. California’s DNA databank
    is part of the Combined DNA Index System (CODIS), a nationwide database that
    enables law enforcement to search DNA profiles collected from federal, state, and
    local collection programs. (See ibid.; Pen. Code, § 299.6, subd. (b); Cal. Dept. of
    Justice (DOJ), Bureau of Forensic Services (BFS), Laboratory Services, DNA
    Analysis,  [as of Apr. 2, 2018].) DNA profiles
    stored by the DNA Laboratory may be accessed by law enforcement agencies.
    (Pen. Code, § 299.5, subd. (f).) The DNA Laboratory must “store, compile,
    correlate, compare, maintain, and use” DNA profiles for forensic casework, for
    comparison with samples found at crime scenes, and for identification of missing
    persons. (Id., § 295.1, subd. (c).)
    Information obtained from an arrestee’s DNA is confidential and may not
    be disclosed to the public. (Pen. Code, § 299.5.) DNA samples and the biological
    material from which they are obtained may not be used “as a source of genetic
    material for testing, research, or experiments, by any person, agency, or entity
    seeking to find a causal link between genetics and behavior or health.” (Id.,
    § 295.2.) Any person who knowingly uses a DNA sample or profile for any
    purpose other than “criminal identification or exclusion purposes” or “the
    identification of missing persons,” or who “knowingly discloses DNA or other
    forensic identification information . . . to an unauthorized individual or agency”
    for any unauthorized reason is subject to criminal prosecution and may be
    imprisoned for up to three years and fined up to $10,000. (Id., § 299.5, subd.
    (i)(1).) The Department of Justice is also subject to civil damages for knowing
    misuse of a sample or profile by any of its employees. (Id., § 299.5, subd.
    (i)(2)(A).)
    The DNA Act provides that if an arrestee is cleared of charges and there is
    no other basis for keeping the information, the arrestee “shall have his or her DNA
    5
    specimen and sample destroyed and searchable database profile expunged from
    the databank program.” (Pen. Code, § 299, subd. (a).) An arrestee may request
    expungement if he or she is released without being charged, if all qualifying
    charges against the arrestee are dismissed, or if the arrestee is found not guilty or
    factually innocent of all qualifying charges. (Id., § 299, subd. (b).) The federal
    legislation establishing CODIS likewise requires participating states to “promptly
    expunge” the DNA profile of any person who is cleared of qualifying charges. (34
    U.S.C. § 12592(d)(2)(A).)
    The DNA Act includes a broad severability provision. The provision
    specifies that the invalidity of certain provisions or their application “shall not
    affect other provisions or applications that can be given effect without the invalid
    provision or application.” (Prop. 
    69, supra
    , § V, subd. (b).)
    B.
    On the afternoon of January 21, 2009, a San Francisco police officer saw
    defendant running away from a police car that had burning tires. Police found
    defendant hiding nearby and searched him. Matches were found in defendant’s
    pocket, a container of oil was found in his backpack, and a road flare and a bottle
    containing a liquid that smelled like gasoline were discovered in the area where he
    had been hiding.
    Defendant was arrested and taken to county jail. There, several hours after
    the initial arrest, a San Francisco sheriff’s deputy asked defendant to swab the
    inside of his cheek for purposes of providing a sample of his DNA. The deputy
    told defendant he was required by law to provide the sample, asked defendant to
    read a form that described the pertinent requirements, and warned defendant that
    refusing to provide a DNA sample was a misdemeanor. Defendant refused.
    On January 22, 2009, a judge of the Superior Court found probable cause to
    believe that defendant committed a public offense for which he could be detained,
    6
    namely, felony arson in violation of Penal Code section 451, subdivision (d). The
    next day, the district attorney filed a felony complaint charging defendant with
    that offense, as well as possession of combustible material or incendiary device
    (id., § 453, subd. (a)), and vandalism (id., § 594, subd. (b)(1)). The complaint also
    charged defendant with misdemeanor refusal to provide a DNA specimen (id.,
    § 298.1, subd. (a)). Defendant was arraigned on the same day and pleaded not
    guilty to the charges.
    Approximately three months later, defendant was tried before a jury.
    Defendant moved for judgment of acquittal on the misdemeanor refusal charge,
    arguing that the Fourth Amendment did not permit the state to compel arrestees to
    furnish DNA samples. The court denied the motion. At trial, defendant admitted
    to setting the police car on fire; he testified that while he regarded setting the fires
    as a justified protest against government overreach, he knew his act was regarded
    as illegal. Defendant also admitted to refusing to provide a DNA sample in
    accordance with Penal Code section 298.1. The jury convicted defendant of all
    charges.
    The trial court ordered defendant to provide a DNA sample before he was
    sentenced, and when defendant initially refused to comply with the order, the court
    authorized the Sheriff’s Department to use reasonable force to obtain the sample.
    Defendant then furnished a DNA sample. The court sentenced defendant to a
    prison term of 16 months on the arson charge, imposed concurrent sentences on
    the charges of possession of combustible material and misdemeanor refusal to
    provide a DNA specimen, and stayed the sentence on the vandalism charge under
    Penal Code section 654.
    On appeal, the Court of Appeal reversed defendant’s conviction for
    refusing to provide a DNA sample. The court held that “the DNA Act, to the
    extent it requires felony arrestees to submit a DNA sample for law enforcement
    7
    analysis and inclusion in the state and federal DNA databases, without
    independent suspicion, a warrant or even a judicial or grand jury determination of
    probable cause, unreasonably intrudes on such arrestees’ expectation of privacy
    and is invalid under the Fourth Amendment of the United States Constitution.”
    We granted review. While the case was still pending, the United States
    Supreme Court issued its decision in 
    King, supra
    , which upheld a similar DNA
    collection requirement against Fourth Amendment challenge. Following King, we
    transferred this case to the Court of Appeal for reconsideration.
    The Court of Appeal again reversed defendant’s conviction. Although the
    court observed that California’s DNA collection law is broader than the Maryland
    law at issue in King, the court declined to decide whether the differences between
    the California law and the Maryland law change the Fourth Amendment calculus
    under King. The Court of Appeal instead rested its decision on the prohibition on
    unreasonable searches and seizures in article I, section 13 of the California
    Constitution. In language closely paralleling its initial decision, the court held that
    “the DNA Act, to the extent it requires felony arrestees to submit a DNA sample
    for law enforcement analysis and inclusion in the state and federal DNA
    databases, without independent suspicion, a warrant or even a judicial or grand
    jury determination of probable cause, unreasonably intrudes on such arrestees’
    expectation of privacy and is invalid under article I, section 13, of the
    Constitution.”
    In the wake of King, other California Courts of Appeal have addressed the
    constitutionality of the DNA Act in the context of reviewing decisions regarding
    the suppression of evidence derived from DNA samples collected from felony
    arrestees. Those courts have concluded that, under King’s reasoning, the
    collection and testing of arrestee DNA samples under the DNA Act does not
    violate the Fourth Amendment.
    8
    We granted review to decide whether the collection and analysis of forensic
    identification DNA database samples from felony arrestees, as required by
    Proposition 69, violates either article I, section 13 of the California Constitution or
    the Fourth Amendment to the United States Constitution.1
    II.
    The Fourth Amendment to the United States Constitution provides, in
    pertinent part: “The right of the people to be secure in their persons, houses,
    papers, and effects, against unreasonable searches and seizures, shall not be
    violated.” Article I, section 13 of the California Constitution provides, in
    essentially identical language: “The right of the people to be secure in their
    persons, houses, papers, and effects against unreasonable seizures and searches
    may not be violated.”
    As the constitutional language itself makes plain, the “touchstone for all
    issues” under both provisions is “reasonableness.” (Ingersoll v. Palmer (1987) 
    43 Cal. 3d 1321
    , 1329; accord, e.g., Riley v. California (2014) 573 U.S. ___, ___ [
    134 S. Ct. 2473
    , 2482].) The question before us is whether it was unreasonable within
    the meaning of one or both of these provisions to require defendant to use a cheek
    swab to provide a DNA sample to jail officials as part of the booking process
    following his arrest for arson. If so, defendant cannot be penalized for failure to
    comply, and his misdemeanor refusal conviction must be reversed. If, on the other
    hand, the requirement was reasonable, then defendant’s conviction stands. (See
    1       Defendant did not invoke the California Constitution in the trial court or in
    his first round of appellate briefing, instead relying solely on the Fourth
    Amendment. The Court of Appeal, however, relied on the California Constitution
    in its decision on remand after King. We accordingly address the questions raised
    under both the Fourth Amendment and article I, section 13 of the California
    Constitution.
    9
    Birchfield v. North Dakota (2016) 579 U.S. ___, ___–___ [
    136 S. Ct. 2160
    , 2172–
    2173].)
    The United States Supreme Court’s decision in King, which was issued
    while this appeal was pending, has significantly altered the terms of the debate.
    After King, defendant no longer argues, as he had argued in the courts below, that
    the Fourth Amendment categorically forbids the mandatory collection of DNA
    from persons who have been arrested but not yet convicted of felony offenses.
    Defendant argues instead that King should be either distinguished on its facts or
    rejected as a matter of state constitutional law. Because both arguments require us
    to consider the import of the United States Supreme Court’s decision in King, we
    will begin there.
    A.
    King came to the high court against the backdrop of increasingly
    widespread use of DNA technology in criminal justice systems nationwide. As
    the court observed, all 50 states and the federal government require the collection
    of DNA samples from individuals who are convicted of felony offenses. In recent
    years, a majority of states and the federal government have also authorized the
    collection of DNA from some or all persons arrested for felony offenses. 
    (King, supra
    , 569 U.S. at p. 445.) Although courts had generally approved the collection
    of DNA samples following conviction, the permissibility of this expansion of
    DNA sampling proved more controversial. The high court granted review in King
    to resolve a conflict among federal and state courts “as to whether the Fourth
    Amendment prohibits the collection and analysis of a DNA sample from persons
    arrested, but not yet convicted, on felony charges.” (Id. at p. 442.)
    The specific question before the court concerned the application of a
    Maryland law that authorized law enforcement authorities to collect DNA samples
    from an individual charged with certain statutorily defined “crime[s] of violence,”
    10
    including murder, rape, first degree assault, kidnapping, arson, and sexual assault,
    as well as burglary and an attempt to commit one of these enumerated crimes.
    
    (King, supra
    , 569 U.S. at p. 443.) The defendant in King had been arrested and
    charged with one such offense, “first- and second-degree assault for menacing a
    group of people with a shotgun.” (Id. at p. 440.) The same day, his cheek was
    swabbed for DNA as part of the booking process. The sample matched DNA that
    had been collected from a rape victim several years earlier, and the defendant was
    charged with and convicted of the rape. Appealing that conviction, defendant
    argued that the DNA sample had been taken in violation of his Fourth Amendment
    rights and should have been suppressed. The Maryland Court of Appeals agreed
    and overturned the rape conviction. (Ibid.)
    The United States Supreme Court reversed. The high court agreed with the
    Maryland court that a buccal swab for the collection of DNA samples—like any
    invasion of the body—is a search within the meaning of the Fourth Amendment,
    “gentle” though the search may be. 
    (King, supra
    , 569 U.S. at p. 446.) But the
    court held that both the initial collection of a DNA sample and its subsequent
    processing pursuant to CODIS procedures is, “like fingerprinting and
    photographing, a legitimate police booking procedure that is reasonable under the
    Fourth Amendment.” (Id. at p. 466.)
    The high court explained that, as a general rule, a search is presumptively
    unreasonable if it is undertaken in the absence of a warrant or individualized
    suspicion of wrongdoing. (Vernonia School Dist. 47J v. Acton (1995) 
    515 U.S. 646
    , 652–653.) But “[i]n some circumstances, such as ‘[w]hen faced with special
    law enforcement needs, diminished expectations of privacy, minimal intrusions, or
    the like, the Court has found that certain general, or individual, circumstances may
    render a warrantless search or seizure reasonable.’ ” 
    (King, supra
    , 569 U.S. at
    p. 447, quoting Illinois v. McArthur (2001) 
    531 U.S. 326
    , 330.) The court
    11
    concluded that the buccal swab of an arrestee on booking falls into a category of
    routine searches, justified by special law enforcement needs, that is properly
    analyzed “by reference to the proposition that the ‘touchstone of the Fourth
    Amendment is reasonableness, not individualized suspicion.’ ” (King, at p. 448.)
    Weighing the privacy-related concerns at stake against law enforcement
    needs, the court concluded that the search was reasonable. On the law
    enforcement side of the balance, the court identified five interrelated governmental
    interests in obtaining the DNA sample. First, the court explained, the state has an
    interest in knowing “ ‘who has been arrested and who is being tried.’ ” 
    (King, supra
    , 469 U.S. at p. 450, quoting Hiibel v. Sixth Judicial Dist. Court of Nev.,
    Humboldt County (2004) 
    542 U.S. 177
    , 191.) “A suspect’s criminal history,” the
    high court continued, “is a critical part of his identity that officers should know
    when processing him for detention,” and “[a] DNA profile is useful to the police
    because it gives them a form of identification to search the records already in their
    valid possession” for the suspect’s criminal history. (King, at pp. 450–451.) In
    this respect, the court said, the profile serves the same purpose as a name or
    fingerprints. (Id. at p. 451.) Second, the high court reasoned, “DNA identification
    can provide untainted information to those charged with detaining suspects and
    detaining the property of any felon,” which is significant because “officers must
    know the type of person whom they are detaining, and DNA allows them to make
    critical choices about how to proceed.” (Id. at p. 452.) Third, the court noted,
    using DNA samples to determine whether the accused has committed other crimes
    furthers the state’s “ ‘substantial interest in ensuring that persons accused of
    crimes are available for trials.’ ” (Ibid.) This is so, it said, because “[a] person
    who is arrested for one offense but knows that he has yet to answer for some past
    crime may be more inclined to flee the instant charges,” thereby presenting “a risk
    to law enforcement officers, other detainees, victims of previous crimes,
    12
    witnesses, and society at large.” (Id. at p. 453.) Fourth, the court explained, “an
    arrestee’s past conduct is essential to an assessment of the danger he poses to the
    public,” which may determine “whether the individual should be released on bail.”
    (Ibid.) And fifth, the court noted, “the identification of an arrestee as the
    perpetrator of some heinous crime may have the salutary effect of freeing a person
    wrongfully imprisoned for the same offense.” (Id. at p. 455.)
    Law enforcement agencies, the court explained, “routinely have used
    scientific advancements in their standard procedures for the identification of
    arrestees” 
    (King, supra
    , 569 U.S. at p. 456), including photographs, body
    measurements, and fingerprints. The court observed that fingerprinting, in
    particular, is “[p]erhaps the most direct historical analogue to the DNA
    technology” at issue in the case (
    id. at p.
    458): fingerprints have long been taken
    for purposes of comparison to identify suspects and for purposes of matching them
    to fingerprints taken from the scene of unsolved crimes, and electronic databases
    are now available that facilitate the comparison (
    id. at pp.
    436, 458–459). DNA
    identification, the court noted, is a “markedly more accurate form of identifying
    arrestees” and the “additional intrusion upon the arrestee’s privacy beyond that
    associated with fingerprinting is not significant.” (Id. at p. 459.) “DNA
    identification,” the court reasoned, “is an advanced technique superior to
    fingerprinting in many ways, so much so that to insist on fingerprints as the norm
    would make little sense to either the forensic expert or a layperson.” (Ibid.)
    Compared to this set of governmental interests, the high court concluded
    that the privacy interests at stake were more limited. To begin with, the court
    explained, the buccal swab used to obtain a DNA sample is a “minimal intrusion.”
    
    (King, supra
    , 569 U.S. at p. 463.) Moreover, the court noted, “[o]nce an
    individual has been arrested on probable cause for a dangerous offense that may
    require detention before trial,” that person has a diminished expectation of privacy
    13
    and “freedom from police scrutiny.” (Ibid.) This diminished expectation
    distinguishes arrestee searches from “the sort of programmatic searches of either
    the public at large or a particular class of regulated but otherwise law-abiding
    citizens” (
    id. at p.
    462), such as checkpoint searches or the drug testing of political
    candidates, for which the court has “insisted on some purpose other than ‘to detect
    evidence of ordinary criminal wrongdoing.’ ” (Id. at p. 463.)
    The high court further concluded that analysis of the DNA sample, once
    collected, does not result in a privacy intrusion that violates the federal
    Constitution. 
    (King, supra
    , 569 U.S. at p. 464.) It explained that the processed
    DNA loci “come from noncoding parts of the DNA that do not reveal the genetic
    traits of the arrestee” and that “law enforcement officers analyze DNA for the sole
    purpose of generating a unique identifying number against which future samples
    may be matched.” (Ibid.) It also noted that Maryland’s DNA law “provides
    statutory protections that guard against further invasion of privacy” (
    id. at p.
    465.);
    in the court’s view, these statutory protections allayed the privacy concerns
    associated with the state’s analysis of the DNA sample (ibid., citing NASA v.
    Nelson (2011) 562 U.S.___, ___ [
    131 S. Ct. 746
    , 750]).
    For these reasons, the court held that “[w]hen officers make an arrest
    supported by probable cause to hold for a serious offense and they bring the
    suspect to the station to be detained in custody, taking and analyzing a cheek swab
    of the arrestee’s DNA is, like fingerprinting and photographing, a legitimate police
    booking procedure that is reasonable under the Fourth Amendment.” 
    (King, supra
    , 569 U.S. at pp. 465–466.)
    B.
    At least at first glance, King would seem to resolve the Fourth Amendment
    question raised in this case. King holds that DNA identification of arrestees is
    reasonable on booking following an arrest supported by probable cause to believe
    14
    the arrestee has committed a serious offense. Defendant in this case was asked to
    provide a cheek swab as part of a routine booking procedure following an arrest
    supported by probable cause to believe he had committed a serious offense—
    namely, felony arson.
    Defendant urges us to take a second look, however. He notes that while
    California’s legal framework for the collection, analysis, and retention of arrestee
    DNA is in many ways similar to the Maryland law upheld in King, it is not
    identical. Defendant highlights three features of the DNA Act in particular that, in
    his view, distinguish this case from King: (1) the DNA Act applies to a broader
    category of arrestees than the Maryland law; (2) the DNA Act, unlike the
    Maryland law, authorizes both collection and testing of DNA samples before an
    accusatory pleading is filed in court and before a judicial determination has been
    made that the charges are valid; and (3) the DNA Act, unlike the Maryland law,
    does not provide for automatic destruction of the DNA sample if the arrestee is
    cleared of felony charges.
    Although these differences between the California and Maryland laws may
    be relevant in another case involving a differently situated arrestee, this case
    involves a defendant who was validly arrested on probable cause to believe he had
    committed felony arson, and who was promptly charged with (and ultimately
    convicted of) that offense. In the context of the particular case before us, we
    conclude that none of the differences to which defendant points meaningfully
    alters the constitutional balance struck in King.
    We begin with defendant’s first argument, about the scope of the DNA
    Act’s collection requirement. Defendant observes that the Maryland law at issue
    in King authorized DNA collection only from those accused of specified serious
    crimes, including a category defined as “crime[s] of violence” under state law,
    whereas the DNA Act authorizes DNA collection from all felony arrestees. 
    (King, 15 supra
    , 569 U.S. at p. 443.) Defendant argues that this difference is important
    because the seriousness of the crime of arrest figures prominently in the high
    court’s balancing analysis: The high court’s opinion states that “the necessary
    predicate of a valid arrest for a serious offense is fundamental” (
    id. at p.
    461), and
    elsewhere uses language that suggests the court was particularly concerned with
    persons arrested for “violent” or “dangerous” crimes (
    id. at pp.
    453, 455). Such a
    limitation makes sense, defendant contends, because such crimes are the kinds of
    crimes that typically yield DNA evidence.
    Defendant appears to read too much into the language on which he relies.
    The high court identified the question before it more generally as “whether the
    Fourth Amendment prohibits the collection and analysis of a DNA sample from
    persons arrested, but not yet convicted, on felony charges.” 
    (King, supra
    , 569
    U.S. at p. 442.) And as a matter of ordinary usage, a felony is considered a
    “serious” offense. (See, e.g., Carachuri-Rosendo v. Holder (2010) 
    560 U.S. 563
    ,
    574 [“A ‘felony,’ we have come to understand, is a ‘serious crime usu[ally]
    punishable by imprisonment for more than one year or by death.’ ”].) Though the
    court also occasionally referred to “violent” and “dangerous” crimes, King did not
    purport to limit its holding to those felonies that happen to be classified as
    “violent” or “dangerous” as a matter of state law, nor did it purport to create a new
    classification of violent offenses as a matter of federal constitutional law.2
    2      States are, of course, under no obligation to classify any particular set of
    crimes as “violent,” and different states often classify similar crimes differently.
    Such “interstate statutory differences do not control the meaning of the Fourth
    Amendment.” 
    (Robinson, supra
    , 47 Cal.4th at p. 1123; cf. Virginia v. Moore
    (2008) 
    553 U.S. 164
    , 176.) Nor does there exist a body of federal constitutional
    law that might supply a relevant classification. (Cf., e.g., Atwater v. City of Lago
    Vista (2001) 
    532 U.S. 318
    , 345 [declining to adopt a classification of “violent”
    misdemeanors for Fourth Amendment purposes].)
    16
    But in any event, even if the federal Constitution permitted states to
    mandate collection of DNA samples only from persons arrested for felonies
    classified as particularly serious or violent, defendant in this case was arrested for
    felony arson in violation of Penal Code section 451, subdivision (d), a crime that is
    classified as a “serious felony” under California law. (See Pen. Code, § 1192.7,
    subd. (c)(14).) Defendant does not dispute the characterization.
    Defendant’s argument would thus seem to amount to a request that we
    reverse his conviction based not on any defect in the DNA Act’s application to his
    case, but based on the Act’s potential application to other, differently situated
    individuals. This is more than he may reasonably ask. The ordinary rule is “that
    one will not be heard to attack a statute on grounds that are not shown to be
    applicable to himself.” (In re Cregler (1961) 
    56 Cal. 2d 308
    , 313 (Cregler).) This
    rule does have limited exceptions—most commonly invoked in free speech
    cases—but none is relevant here. (Sabri v. United States (2004) 
    541 U.S. 600
    ,
    609–610 (Sabri); see, e.g., United States v. Mitchell (3d Cir. 2011) 
    652 F.3d 387
    ,
    415, fn. 26 (en banc) (Mitchell) [felony arrestee could not raise a successful facial
    challenge to federal DNA collection law on the ground that it applies to
    misdemeanor arrestees and is therefore overbroad]; cf. Rakas v. Illinois (1978) 
    439 U.S. 128
    , 133–134 [“ ‘Fourth Amendment rights are personal rights which, like
    some other constitutional rights, may not be vicariously asserted.’ ”].) Outside of
    these limited exceptions, and “absent a good reason, we do not extend an
    invitation to bring overbreadth claims.” (Sabri, at p. 610.) No such reason
    appears in this case.
    Defendant next points out that the Maryland law upheld in King permitted
    collection of a DNA sample only of arrestees “charged” with qualifying crimes
    (Md. Code Ann., Pub. Saf., § 2-504(b)(1)), and prohibited officials from testing
    the sample or loading the profile into the statewide database until after the arrestee
    17
    was arraigned and a judicial officer determined that the arrest was based on
    probable cause (id., § 2-504(d)(1)). The DNA Act, by contrast, allows collection
    “immediately following arrest” and provides that the samples shall “immediately”
    be forwarded to the laboratory for analysis. (Pen. Code, § 295(i)(1)(C).)
    Defendant argues that these differences in the time prescribed for the collection
    and testing of DNA samples tip the balance against their constitutionality.
    There are two elements to this argument: one concerning the timing of the
    collection, the other concerning the timing of analysis. As to the timing of
    collection, there is no reason to believe that the differences between California’s
    law and Maryland’s change the Fourth Amendment balance applicable in this
    case. Although the text of the DNA Act does purport to authorize the collection
    “immediately following arrest,” that provision was not invoked and is not at issue
    here. Rather, jail officials in this case sought to collect a sample of defendant’s
    DNA on booking, as part of the routine collection of identifying information. And
    King, once again, upheld DNA collection as a “legitimate police booking
    procedure,” like fingerprinting or photographing, that enables jail officials to know
    whom they have taken into custody. 
    (King, supra
    , 569 U.S. at p. 466, italics
    added.) King itself involved a sample collected on booking. (Id. at p. 441; see
    King v. State (Md. 2012) 
    42 A.3d 549
    , 557.)3 And there are practical reasons for
    3     In his brief, defendant read the Maryland law’s reference to arrestees
    “charged” with certain offenses as prohibiting the collection of DNA until a
    prosecutor decides whether to file qualifying charges following arrest. (See Md.
    Code. Ann., Pub. Saf., § 2-504(b)(1).) But the Attorney General notes that in
    Maryland, charges are often filed by the police officer, rather than the prosecutor.
    (Md. Rules, rule 4-211(b)(2).) The high court’s opinion in King did not address
    the meaning or significance of this provision of the Maryland law; its analysis was
    focused not on the nature of the charging decision, but on the fact of an arrest
    supported by probable cause.
    18
    collecting the required DNA sample at the time of booking, along with taking
    photographs and fingerprints. Among other things, if the arrestee is released
    pending adjudication, officials may not have another opportunity. (See Mario W.
    v. Kaipio (Ariz. 2012) 
    281 P.3d 476
    , 482 [“If . . . a juvenile is released pending
    adjudication and later fails to appear for trial without previously having submitted
    a buccal sample, the opportunity to obtain a DNA profile for identification
    purposes will have been lost. The State has an important interest in locating an
    absconding juvenile and, perhaps years after charges were filed, ascertaining that
    the person located is the one previously charged.”].)
    As to the second point, defendant argues that it is unreasonable for officials
    to proceed to test the DNA sample once collected, and to upload an arrestee’s
    profile to the state DNA databank, before a judicial officer has found probable
    cause to support the arrest or before charges have been filed. Defendant argues
    that it is this step—the testing and recording of the arrestee’s DNA identification
    profile—that “represents the far greater intrusion upon privacy.” And a provision
    like Maryland’s ensures that this step is not taken before there is third party
    confirmation that the defendant was validly arrested and that he or she will face
    legal process for a felony offense.
    19
    Defendant, who has never contested that his arrest was based on probable
    cause,4 made no similar argument in the trial court; he argued that it was
    impermissible to require him to submit a DNA sample at all, not that it was
    unreasonable to do so without a guarantee that the analysis of the sample would be
    delayed until probable cause was confirmed by a neutral magistrate or charges
    were filed. We observe, however, that the reasoning of King itself does not lend
    substantial support to the argument that such a guarantee is required under these
    circumstances. Again, King approved “DNA identification”—which necessarily
    involves both taking and analyzing the sample—as a “legitimate police booking
    procedure” that enables law enforcement to know whom they have in custody.
    
    (King, supra
    , 569 U.S. at pp. 465–466.) That interest is one that attaches as soon
    as the suspect is “formally processed into police custody.” (Id. at pp. 449–450.)
    The court attached no significance to the timing provision of the Maryland statute
    on which defendant relies. The point was, rather, raised primarily in the dissenting
    opinion, which argued that delaying DNA testing until arraignment undermined
    the argument that the requirement qualifies as a reasonable booking procedure.
    (Id. at pp. 471–472 (dis. opn. of Scalia, J.).)
    Defendant contends that the timing of analysis nevertheless ought to figure
    in the equation because, as a practical matter, officers ordinarily will not receive a
    4       On the contrary, it appears that defendant acknowledged from the outset
    that there was probable cause to arrest him. While being placed in a patrol car at
    the scene, defendant spontaneously stated, “I didn’t think it would work” and
    noted that the officer who initially observed him in the act had “[p]erfect timing,
    him coming up the hill like that.” According to his own testimony at trial,
    moreover, he anticipated he would be charged for his acts. Justified as his protest
    was, he testified, he knew “how the legal system works” and that “[t]hey [we]re
    going to regard this as an illegal act.”
    20
    suspect’s DNA profile until well after booking in any event. When officers make
    a warrantless arrest and take a suspect into custody, due process ordinarily
    requires that a judicial officer make a probable cause determination promptly after
    booking—ordinarily within 48 hours—to justify continued pretrial detention.
    (County of Riverside v. McLaughlin (1991) 
    500 U.S. 44
    , 58–59.) (No such
    requirement applies if the arrestee is released from detention. (In re Walters
    (1975) 
    15 Cal. 3d 738
    , 743; see also Pen. Code, § 849, subd. (a).)) By contrast,
    defendant notes, in California it has typically taken much longer—at the time of
    briefing, an average of 30 days—to generate an identification profile from an
    arrestee’s DNA sample. (See 
    King, supra
    , 569 U.S. at p. 454 [citing the same
    statistic].) Defendant argues that in view of the delays already associated with
    sample processing, it would pose a negligible burden for officials to postpone
    processing until a judge has determined whether probable cause exists and a
    prosecutor has decided whether to file charges.
    Defendant’s point about average processing times is not one that escaped
    the high court’s notice in King; as noted, the court itself cited the same numbers.
    The court nevertheless concluded that DNA identification is a reasonable booking
    procedure, without suggesting that its reasonableness might vary depending on
    average processing times. The reasons for this are not difficult to discern. For one
    thing, individual DNA samples may be processed more quickly than average: The
    court noted the states’ submission that some DNA identification samples in
    California have been processed significantly more quickly than others. 
    (King, supra
    , 569 U.S. at p. 454.) Moreover, as is often the case in areas of fast-moving
    technological developments, average processing times are liable to change; the
    high court had been told that the technological capacity already exists to analyze
    DNA samples in a matter of minutes, rather than days or weeks, and that
    technology is likely to become more widespread in the near future. (Id. at p. 460;
    21
    see Rapid DNA Act of 2017, Pub.L. No. 115-50 (Aug. 18, 2017) 131 Stat. 1001;
    see also 42 U.S.C. §§ 14131(a), 14135a.) The court “[took] account of these
    technical advances” (King, at p. 460) in evaluating the reasonableness of DNA
    collection and testing as a means of “prompt identification” (
    id. at p.
    459). Given
    all this, we cannot proceed on the assumption that a rule delaying the collection or
    processing of samples until after a judicial probable cause finding or arraignment
    would pose no meaningful risk of interference with the central interest identified
    in King: the accurate identification of arrestees who are taken into police custody.
    Defendant argues, not unreasonably, that we should decide this case in light
    of the conditions that prevailed at the time he refused to provide the sample, not in
    light of technological advances that might make it possible to process DNA
    samples more quickly in the future. But considering the matter from this vantage
    point does not help defendant’s case. If we assume that defendant’s sample would
    not have been processed significantly faster than the average of 30 days, as
    defendant would have us do, then we would also be bound to conclude that
    defendant would have, de facto, received the very delay he seeks: The record
    indicates that a judge found probable cause to support defendant’s felony arrest a
    little more than 24 hours after he was arrested, and he was arraigned within 48
    hours, as the law requires. In a world of 30-day processing times, defendant’s
    sample would not have been processed, or his DNA profile uploaded to the state
    DNA databank, before these events occurred.
    Although defendant himself was charged and convicted, we acknowledge
    defendant’s concern about the collection of DNA samples from other individuals
    who are booked into custody but who ultimately will never be charged with a
    qualifying crime, or against whom qualifying charges will ultimately be dismissed.
    Voters responded to that concern by providing for a particular remedy—
    expungement of the DNA sample and associated records—when the suspect is
    22
    cleared of qualifying charges. As King illustrates, voters could also have chosen
    to require that all sample processing be postponed until after arraignment,
    regardless of technological capacity to proceed more quickly. But given the basic
    logic of King, we cannot say that the choice voters made is one that undermines
    the reasonableness of the search in this case.
    Justice Liu suggests that for purposes of deciding reasonableness of an
    arrestee’s search, an arrest should not be considered valid until there has been a
    judicial determination of its validity. (Dis. opn. of Liu, J., post, at pp. 1–2.) There
    is, however, a meaningful difference between the requirement of a valid arrest and
    a requirement that a neutral magistrate make such a determination. For example,
    in the related context of searches incident to arrest—where a valid arrest is also
    essential—there is no such preapproval requirement. (See United States v.
    Robinson (1973) 
    414 U.S. 218
    , 219–224 [approving search of the person at time of
    valid arrest made without warrant]; People v. Brisendine (1975) 
    13 Cal. 3d 528
    ,
    532–534 (Brisendine) [approving search for weapons upon a warrantless arrest,
    under circumstances requiring prolonged proximity to arrestees].) The arrestee
    may have an exclusionary remedy if the arrest is later determined to have been
    illegal (see 6 LaFave, Search and Seizure (5th ed. 2012) § 11.4(d), pp. 407–408),
    but the search’s reasonableness does not depend on prior judicial authorization for
    the arrest. Here, there is no dispute that the arrest was valid. To the extent the
    dissenting opinions argue for a prophylactic rule delaying the analysis of an
    arrestee’s DNA sample until probable cause for the arrest has been judicially
    determined, we again note that defendant raised no such argument in the trial court
    and we decline to decide the constitutional necessity of such a rule in a case in
    which probable cause has never been contested.
    This brings us to defendant’s final point, concerning the adequacy of the
    DNA Act’s expungement procedures. As defendant notes, under the Maryland
    23
    law at issue in King, an arrestee who is later exonerated is entitled to automatic
    destruction of his or her DNA sample and associated records. 
    (King, supra
    , 569
    U.S. at pp. 443–444.) Under the DNA Act, by contrast, an exonerated arrestee
    ordinarily must file a written request for expungement of DNA records. (Pen.
    Code, § 299, subds. (a) & (b).)5 Provisions of the Act can be read to suggest,
    moreover, that a trial court may not act on such a request before 180 days have
    elapsed, and the court has unreviewable discretion to grant or deny the request.
    (Id., subd. (c)(1) & (c)(2)(D).) Defendant argues that these provisions, by contrast
    to Maryland’s automatic destruction provisions, mean that a DNA profile can be
    generated and maintained in the state database even after a suspect’s arrest has
    been found to be mistaken or unlawful. What is more, he argues, the provisions
    make it possible for the state to retain the DNA sample and associated records for
    an extended period of time—perhaps even indefinitely—after the prosecutor has
    declined to file or has dismissed charges, or after those charges have failed to yield
    a conviction. In sum, defendant argues, the DNA Act’s expungement provisions
    are insufficient to protect the privacy rights of felony arrestees who are later found
    to have been wrongly arrested or who are cleared of wrongdoing.
    King does not speak directly to the issue defendant raises concerning the
    adequacy of the DNA Act’s expungement procedures. Although the high court
    mentioned Maryland’s automatic destruction provisions in passing, it attached no
    significance to them in its constitutional analysis. 
    (King, supra
    , 569 U.S. at
    pp. 443–444.) Rather, the court responded to privacy concerns about the state’s
    5     A different provision of the DNA Act requires the Department of Justice
    DNA Laboratory to “remove [a] suspect sample from its databank files and
    databases” after two years upon confirmation that the “person is no longer a
    suspect in a criminal investigation.” (Pen. Code, § 297, subd. (c)(2).) The parties
    have not addressed the relevance of this provision, if any.
    24
    processing of DNA samples by emphasizing features of the Maryland law that are
    shared by California’s: namely, the analysis of a sample involves the processing
    only of loci from “noncoding parts of the DNA that do not reveal the genetic traits
    of the arrestee,” and the law strictly prohibits the misuse of DNA records for any
    purpose other than identification. (Id. at p. 464; see 
    id. at p.
    465; Pen. Code,
    § 299.5.)
    The court’s failure to mention the expungement provisions does not
    necessarily mean that they are irrelevant to the constitutional analysis, however.
    To be sure, the retention of an arrestee’s fingerprints, photographs, and other
    identifying information in law enforcement files generally has not been thought to
    raise constitutional concerns, even though the arrestee may later be exonerated.
    (Loder v. Municipal Court (1976) 
    17 Cal. 3d 859
    , 864–869; People v. McInnis
    (1972) 
    6 Cal. 3d 821
    , 826.) But the question defendant raises is whether, given the
    uniquely sensitive nature of DNA information, a different rule should apply here:
    one that calls not only for expungement, but for automatic expungement of an
    arrestee’s DNA sample, DNA identification profile, or both after an arrest has
    been shown to be invalid or after an arrestee is cleared of charges, or both.
    Whether the Fourth Amendment requires this added protection for the
    wrongly arrested or exonerated is, however, a question we must leave for another
    day, because defendant in this case is neither. Defendant has not been found to
    have been wrongly arrested; indeed, he has never challenged the validity of his
    arrest. Nor was he cleared of the charges that formed the basis for his arrest; he
    was promptly charged with that offense and was later convicted as charged.
    Although our dissenting colleagues argue otherwise (dis. opn. of Liu, J., post, at
    pp. 7–8; dis. opn of Cuéllar, J., post, at pp. 25–26), we are aware of no support for
    the proposition that an arrestee who, like defendant, has never claimed to be
    entitled to expungement, is nevertheless entitled to challenge the adequacy of
    25
    expungement procedures. (See 
    Mitchell, supra
    , 652 F.3d at p. 412 [arrestee who
    had never provided a sample and who had never sought expungement was “not in
    a position” to challenge the adequacy of the expungement provisions of the federal
    DNA collection statute].)
    Again, the ordinary rule is “that one will not be heard to attack a statute on
    grounds that are not shown to be applicable to himself.” 
    (Cregler, supra
    , 56
    Cal.2d at p. 313.) Further, “a court will not consider every conceivable situation
    which might arise under the language of the statute and will not consider the
    question of constitutionality with reference to hypothetical situations.” (Ibid.) By
    focusing on the facts presented by the case before us, we avoid premature
    judgment of constitutional questions, including “ ‘premature interpretatio[n] of
    statutes’ on the basis of factually bare-bones records.” 
    (Sabri, supra
    , 541 U.S. at
    p. 609, quoting United States v. Raines (1960) 
    362 U.S. 17
    , 22.)
    Restraint is particularly warranted here because much of defendant’s
    argument depends on assertions about the workings of the expungement
    procedures that are as yet untested and unproved. The record before us reveals
    nothing, for example, about how the expungement provisions operate in a case in
    which a judge finds no probable cause to support the arrest. The statute does make
    clear that a person who is found to have been wrongly arrested is entitled to
    expungement: it says that “a person who has no past or present qualifying
    offense” may make a request for expungement if, among other things, no
    qualifying charges have been filed “within the applicable period allowed by law”
    or if qualifying charges “have been dismissed prior to adjudication by a trier of
    fact.” (Pen. Code, § 299, subd. (b)(1).) But the requirement that the arrestee make
    a written request with supporting documentation from the court or the district
    attorney, for example, appears to be aimed at dispelling any doubt as to whether
    qualifying charges may still be filed against the arrestee. (Id., § 299, subd.
    26
    (c)(2)(B).) It is unclear whether or how this requirement would apply in a case in
    which a judge has ruled from the outset that the defendant’s felony arrest was
    unsupported by probable cause.
    Much the same is true about defendant’s concern that the state may
    indefinitely retain DNA information of a person who, though arrested, has been
    found innocent of any crime. Defendant contends that a prosecutor may
    unilaterally block expungement by objecting for any reason, and a trial court
    likewise may deny expungement in its unconstrained discretion. It is not clear that
    he is correct on either score. It is true that the DNA Act describes a process that
    permits prosecutors to file objections to expungement (Pen. Code, § 299, subd.
    (c)(2)(D)), and speaks of trial court “discretion” to grant or deny an expungement
    request (id., § 299, subd. (c)(1)). But the DNA Act also provides that if there is no
    other legal basis for retaining the information, an exonerated arrestee “shall have
    his or her DNA specimen and sample destroyed and searchable database profile
    expunged from the databank program.” (Pen. Code, § 299, subd. (a), italics
    added.) Federal law likewise provides that a state participating in CODIS “shall
    promptly expunge” from that database the DNA profile of any person who is later
    cleared of qualifying charges. (34 U.S.C. § 12592(d)(2)(A).) And to the extent
    there is any question about the proper interpretation of the statute, it might well be
    resolved by reference to the usual rule that a statute will be interpreted to avoid
    serious constitutional questions if such an interpretation is fairly possible. (See,
    e.g., People v. Gutierrez (2014) 
    58 Cal. 4th 1354
    , 1373.) Whether legislation may
    deprive the appellate courts of all modes of reviewing a trial court’s order, as
    section 299, subdivision (c)(1) might appear to do, poses such a question. (See
    Cal. Const., art VI, §§ 10, 11 [jurisdiction of appellate courts over appeals and
    writs]; Leone v. Medical Board (2000) 
    22 Cal. 4th 660
    , 668 [Legislature may not
    27
    restrict appellate review in a manner that would substantially impair courts’
    constitutional powers].)
    Nor does a trial court order appear to be a necessary prerequisite to
    expungement. As the Attorney General points out, the California Department of
    Justice has created a “streamlined” process whereby eligible individuals may seek
    expungement directly from the Department, using a publicly available two-page
    form.6 Defendant does not question the Department’s authority to create this
    alternative, “streamlined” expungement process. (See Pen. Code, § 295, subd.
    (h)(1) [authorizing the Department to adopt policies and enact regulations for the
    implementation of the DNA Act].) And although he notes that a trial court might
    have to get involved if the Department denies a valid expungement request, he
    points to no case in which such a thing has occurred.
    Because defendant never sought expungement—and indeed, has never
    claimed to be entitled to seek expungement, since he was both charged with and
    ultimately convicted of a qualifying crime—we have no occasion here to resolve
    any questions that might arise about the implementation of the expungement
    provisions in other cases. It suffices to note that many of defendant’s assertions
    about the operation of the expungement process are, at this point, necessarily
    speculative. This court ordinarily does not issue constitutional rulings based on
    speculation, and we will not do so here. (See, e.g., 
    Cregler, supra
    , 56 Cal.2d at
    6      California DOJ, Streamlined DNA Expungement Application Form,
     [as of Apr. 2, 2018]. As the
    Attorney General notes, the Frequently Asked Questions page on the DOJ website
    indicates that the expedited expungement process is generally completed within
    two to four weeks. (See  [as of
    Apr. 2, 2018].)
    28
    p. 313; Pacific Legal Foundation v. California Coastal Com. (1982) 
    33 Cal. 3d 158
    , 172.)7
    In short, although the DNA Act differs in some ways from the Maryland
    law at issue in King, none of those differences affects the Fourth Amendment
    analysis in the specific case before us. King holds that a cheek swab is a
    reasonable booking procedure for individuals who are arrested for serious
    offenses, and defendant was asked to provide a cheek swab upon being booked
    after a valid arrest for a serious offense. Defendant’s conviction for failing to
    submit a sample of his DNA therefore did not violate the Fourth Amendment to
    the federal Constitution.
    7       As Justice Cuéllar notes in his dissent (post, pp. 29–30), after we granted
    review in this case, the Legislature enacted versions of Penal Code sections 298
    and 299 to become operative were this court to affirm the Court of Appeal’s
    decision below. These include provisions for more automatic expungement and
    for delay in analyzing samples until probable cause for the arrest has been
    judicially determined. (Stats. 2015, ch. 487, §§ 3, 5.)
    It goes without saying that our job is not to decide which version of the
    statute we prefer, but instead to determine whether the DNA Act, as enacted by
    California voters, is constitutional as applied to defendant in the case before us.
    The legislative amendments themselves make this clear. The Legislature did not
    attempt to substitute these statutory provisions for those the voters approved;
    whether it could do so, consistent with its role under Proposition 69, is therefore a
    question not presented here. (See Prop. 
    69, supra
    , § V, subd. (c) [amendments
    may be made only “to enhance the use of DNA identification evidence for the
    purpose of accurate and expeditious crime-solving and exonerating the
    innocent”].) The Legislature instead enacted the provisions as a kind of fallback
    measure, providing that the amendments would come into force only if we affirm
    the lower court’s ruling as to the statutory sections’ unconstitutionality as applied
    in this case (presumably on a basis that would not equally undermine the validity
    of the Legislature’s conditional amendments). We accordingly focus solely on the
    law as the voters enacted it, as applied to the facts of the case before us.
    29
    III.
    Defendant argues, and the Court of Appeal concluded on remand from
    King, that even if requiring him to furnish a DNA sample as part of the booking
    process did not violate the Fourth Amendment, it violated the parallel prohibition
    on unreasonable searches and seizures in article I, section 13 of the California
    Constitution.
    We evaluate the constitutionality of searches and seizures under our state
    Constitution by employing the same mode of analysis that the high court applied
    in 
    King, supra
    , 569 U.S 435. That is, we determine whether the intrusion on the
    defendant’s expectation of privacy is unreasonable by applying “a general
    balancing test ‘weighing the gravity of the governmental interest or public concern
    served and the degree to which the [challenged government conduct] advances
    that concern against the intrusiveness of the interference with individual liberty.’ ”
    (Hill v. National Collegiate Athletic Assn. (1994) 
    7 Cal. 4th 1
    , 29–30, quoting
    Ingersoll v. 
    Palmer, supra
    , 43 Cal.3d at p. 1338.) Defendant does not argue
    otherwise. He instead argues that we should reject King’s balancing of these
    interests as a matter of state constitutional law.
    In addressing defendant’s argument, we reaffirm several long-established
    principles. First, the California Constitution is, and has always been, “a document
    of independent force” (American Academy of Pediatrics v. Lungren (1997) 
    16 Cal. 4th 307
    , 325) that sets forth rights that are in no way “dependent on those
    guaranteed by the United States Constitution” (Cal. Const., art. I, § 24). “As an
    historical matter, article I and its Declaration of Rights was viewed as the only
    available protection for our citizens charged with crimes, because the federal
    Constitution and its Bill of Rights was initially deemed to apply only to the
    conduct of the federal government.” (Raven v. Deukmejian (1990) 
    52 Cal. 3d 336
    ,
    352–353.) While the setting changed following ratification of the Fourteenth
    30
    Amendment to the United States Constitution and the selective incorporation of
    the Bill of Rights, it remains a basic tenet of our system of federalism that “the
    nation as a whole is composed of distinct geographical and political entities bound
    together by a fundamental federal law but nonetheless independently responsible
    for safeguarding the rights of their citizens.” 
    (Brisendine, supra
    , 13 Cal.3d at
    p. 550.)
    Second, although decisions of the United States Supreme Court interpreting
    parallel federal text are not binding, we have said they are “entitled to respectful
    consideration.” (People v. Teresinski (1982) 
    30 Cal. 3d 822
    , 836 (Teresinski); cf.,
    e.g., Gabrielli v. Knickerbocker (1938) 
    12 Cal. 2d 85
    , 89 [“[C]ogent reasons must
    exist before a state court in construing a provision of the state Constitution will
    depart from the construction placed by the Supreme Court of the United States on
    a similar provision in the federal Constitution.”].) This approach reflects the
    “respect due to the decision of that high tribunal, the fact that to it has been
    committed, by the consent of the states, the ultimate vindication of liberty and
    property against arbitrary and unconstitutional state legislation.” (People v. Budd
    (1889) 
    117 N.Y. 1
    , 13, affd. Budd v. New York (1892) 
    143 U.S. 517
    , cited in
    
    Gabrielli, supra
    , 12 Cal.2d at p. 89.)
    We have had several occasions to address the application of these principles
    in the context of search and seizure law in particular. Today, following a 1982
    state constitutional amendment passed by voter initiative, the United States
    Supreme Court’s interpretation of the Fourth Amendment is often not only
    persuasive, but controlling in criminal cases: Under Proposition 8, the “Right to
    Truth-in-Evidence” (Cal. Const., art. I, § 28, subd. (f)(2)), added by voters in
    1982, the exclusionary rule does not apply to a search or seizure that violates
    article I, section 13, but does not violate the Fourth Amendment, and the fruits of
    such a search or seizure are admissible in a criminal trial. This means that in
    31
    California criminal proceedings, issues related to the suppression of evidence
    seized by police are, in effect, governed by federal constitutional standards. (E.g.,
    People v. Lenart (2004) 
    32 Cal. 4th 1107
    , 1118; see In re Lance W. (1985) 
    37 Cal. 3d 873
    , 891 [upholding Proposition 8].) But when voters later enacted an
    initiative measure that would have eliminated this court’s ability to independently
    construe the California Constitution’s provisions granting certain rights to criminal
    defendants, including the right to be free of unreasonable searches and seizures,
    we explained that such far-reaching change could be accomplished only by
    constitutional revision: While our law has long reflected a “general principle or
    policy of deference to United States Supreme Court decisions,” the initiative
    measure could not “mandate the state courts’ blind obedience thereto, despite
    ‘cogent reasons,’ ‘independent state interests,’ or ‘strong countervailing
    circumstances’ that might lead our courts to construe similar state constitutional
    language differently from the federal approach.” (Raven v. 
    Deukmejian, supra
    , 52
    Cal.3d at p. 353.)8
    Even before the passage of Proposition 8, this court ordinarily resolved
    questions about the legality of searches and seizures by construing the Fourth
    Amendment and article I, section 13 in tandem. (E.g., People v. Triggs (1973) 8
    8      Our colleagues in dissent would go further; they argue that we should take
    no special account of the federal high court’s interpretation of language common
    to the United States and California Constitutions. (See dis. opn. of Liu, J., post,
    pp. 11–12; dis. opn. of Cuéllar, J., post, pp. 4–5.) But as Raven v. Deukmejian
    made clear in rejecting an effort to eliminate our independent interpretive
    authority altogether, the approach we have described is neither a relic of a long-
    distant past nor a recent innovation. We will accordingly follow this court’s long-
    standing policy and practice of giving meaningful and careful consideration to
    federal high court decisions construing parallel constitutional text, without in any
    way denying or denigrating our power and duty to depart from those decisions
    when sufficient reasons appear.
    
    32 Cal. 3d 884
    , 892, fn. 5 [“At least since the advent of Wolf v. Colorado (1949) 
    338 U.S. 25
    , we have treated the law under article I, section 19 [now section 13], of
    our state Constitution as ‘substantively equivalent’ to the Supreme Court’s
    construction of the Fourth Amendment.”].) On various occasions, however, this
    court has also decided questions pertaining to the legality of searches and seizures
    solely under article I, section 13, when the United States Supreme Court had not
    yet decided the parallel question under the Fourth Amendment. (See, e.g., People
    v. Ruggles 
    (1985) 39 Cal. 3d at 1
    , 11 [“Rather than await more definitive guidance
    [from the United States Supreme Court], we turn to article I, section 13 of the
    California Constitution”]; People v. Cook (1985) 
    41 Cal. 3d 373
    , 376, fn. 1
    [similar].) And on some of those occasions, the high court later spoke to the
    question and reached a contrary conclusion under the Fourth Amendment. We
    have then been confronted with the question whether to adhere to our own
    precedent construing article I, section 13, as a matter of stare decisis, or instead to
    abandon our precedent in favor of the high court’s decision. (See 
    Brisendine, supra
    , 13 Cal.3d at p. 552 [adhering to People v. Superior Court (Simon) (1972) 
    7 Cal. 3d 202
    , notwithstanding the United States Supreme Court’s later decision in
    United States v. 
    Robinson, supra
    , 
    414 U.S. 218
    ]; People v. Cook (1978) 
    22 Cal. 3d 67
    , 88 [adhering to the rule of Theodor v. Superior Court (1972) 
    8 Cal. 3d 77
    ,
    notwithstanding the United States Supreme Court’s later decision in Franks v.
    Delaware (1978) 
    438 U.S. 154
    ].)
    Here, in contrast to many of our earlier cases, the United States Supreme
    Court has resolved the question before us under the Fourth Amendment. The
    question is thus not whether we should abandon our own contrary precedent, and
    any reliance interests that may have grown up around it, but whether we should
    33
    reject the high court’s Fourth Amendment guidance.9 Confronted with a similar
    situation in Teresinski, in which this court’s Fourth Amendment ruling had been
    overturned by the United States Supreme Court in United States v. Crews (1980)
    
    445 U.S. 463
    , we declined an invitation to reach the same conclusion based on
    article I, section 13, finding “no reasons . . . to justify rejecting the teaching of the
    Supreme Court” on the issue presented. 
    (Teresinski, supra
    , 30 Cal.3d at p. 836.)
    The question is whether adequate reasons are present here to conclude, despite
    King, that California voters exceeded constitutional bounds in mandating the
    collection of DNA sample from an individual arrested and booked on probable
    cause to believe he had committed a serious offense.
    Defendant argues there are several such reasons. To begin with, he argues
    that King should be rejected because its central premise is faulty. King concluded
    that DNA collection from persons arrested for serious offenses serves a legitimate
    governmental interest in safely and accurately processing and identifying the
    persons they take into custody. Defendant argues, however, that arrestee DNA
    information is not used to determine an arrestee’s identity, but “solely for
    investigation of possible other crimes.” Echoing the dissenting opinion in King
    (supra, 569 U.S. at pp. 467–469 (dis. opn. of Scalia, J.)), defendant argues that
    9       The dissenting opinions ask why “the order in which this court decides an
    issue vis-à-vis the high court” should be of any significance. (Dis. opn. of Cuéllar,
    J., post, at p. 8; see also dis. opn. of Liu, J., post, at p. 12.) In reviewing this
    court’s past practice, our answer is straightforward: in instances where this court
    had previously decided an issue, that decision carried the persuasive force of stare
    decisis we always accord our own precedents, which had then to be balanced
    against the persuasive force of the contrary United States Supreme Court decision.
    In instances where we had not previously decided an issue, no similar
    counterbalance existed.
    34
    gathering DNA information for this purpose is unreasonable in the absence of a
    warrant or individualized suspicion.
    In evaluating defendant’s argument, we do not write on a blank slate. As
    noted, in 
    Robinson, supra
    , 
    47 Cal. 4th 1104
    , this court upheld against a Fourth
    Amendment challenge the practice of mandatory collection of DNA samples from
    convicted felons. This court so held precisely because of the capacity of DNA
    sampling to provide accurate and reliable identification of criminal offenders.
    This court recognized that DNA samples, like fingerprints, may also be used to
    establish a suspect’s involvement in crimes. (Id. at pp. 1120–1121.) Indeed, the
    DNA sample taken from the defendant in Robinson was used for that purpose, and
    led to his prosecution for an unrelated crime. But this court concluded that the
    search was reasonable because DNA testing is, like fingerprinting, a means of
    identification, and “individuals in lawful custody cannot claim privacy in their
    identification.” (Id. at p. 1121.)
    Robinson, like King, recognized that suspects can change their names,
    assume a false identity using forged documents, change their hair color, have
    tattoos removed, have plastic surgery, and change their eye color with contact
    lenses. But it is impossible to alter a DNA profile. Thus, as Robinson explained,
    “ ‘for purposes of identifying “a particular person” as the defendant, a DNA
    profile is arguably the most discrete, exclusive means of personal identification
    possible.’ ” 
    (Robinson, supra
    , 47 Cal.4th at p. 1134, quoting State v. Dabney
    (Wis. 2003) 
    663 N.W.2d 366
    , 372.) “ ‘ “A genetic code describes a person with
    far greater precision than a physical description or a name.” ’ ” (Ibid.) For that
    reason, this court upheld an arrest warrant describing the arrestee by only his DNA
    profile. (Robinson, at p. 1137.)
    California law, like federal law, has also recognized that identification of
    arrestees is not an end in itself; rather, the primary purpose of identification is to
    35
    facilitate the gathering of information about the arrestee contained in police
    records, which in turn informs decisions about how to proceed with the arrestee.
    (Loder v. Municipal 
    Court, supra
    , 17 Cal.3d at pp. 866–867 [upholding limited
    retention and use of arrest records, including fingerprints and other identifying
    information].) Our law is thus consistent with the high court’s observation that
    “[t]he task of identification necessarily entails searching public and police records
    based on the identifying information provided by the arrestee to see what is
    already known about him.” 
    (King, supra
    , 569 U.S. at p. 451.) “In this respect the
    use of DNA for identification is no different than matching an arrestee’s face to a
    wanted poster of a previously unidentified suspect; or matching tattoos to known
    gang symbols to reveal a criminal affiliation; or matching the arrestee’s
    fingerprints to those recovered from a crime scene. . . . [DNA testing] uses a
    different form of identification than a name or fingerprint, but its function is the
    same.” (Ibid.)
    As counsel confirmed at oral argument, defendant does not dispute that it is
    reasonable for officers to check an arrestee’s fingerprints against “electronic
    databases of known criminals and unsolved crimes.” 
    (King, supra
    , 569 U.S. at
    p. 451.) This, he says, is because fingerprints are capable of serving a “genuine”
    identification purpose, while a DNA profile is not. To be sure, a DNA profile is
    not, at least under present technological conditions, generated immediately or
    nearly immediately, in the manner of fingerprints. But as the high court noted in
    King, the immediate availability of fingerprints for identification purposes is also a
    relatively recent development; before the FBI introduced its electronic fingerprint
    database in 1999, processing fingerprint submissions often took “ ‘weeks or
    months.’ ” (Id. at p. 459.) Such delays have not been thought to undermine the
    basic identification purposes of the information. (See, e.g., United States v. Kelly
    (2d Cir. 1932) 
    55 F.2d 67
    , 69, 70 [“Finger printing seems to be no more than an
    36
    extension of methods of identification long used in dealing with persons under
    arrest for real or supposed violations . . . .” “It can really be objected to only
    because it may furnish strong evidence of a man’s guilt.”].)
    As the high court explained in King, “[t]he question of how long it takes to
    process identifying information obtained from a valid search goes only to the
    efficacy of the search for its purpose of prompt identification, not the
    constitutionality of the search.” 
    (King, supra
    , 569 U.S. at p. 459.) Even if a DNA
    profile is not generated until weeks or months after the initial booking, the
    information it yields about the arrestee and his criminal history can still have an
    “important bearing” on the processing of the arrestee—whether, for example, to
    revisit an initial determination to release the arrestee or to impose new release
    conditions. (Id. at p. 460.) Information obtained after initial booking may also
    influence the jailer’s decision about where to house the arrestee.
    To the extent defendant means to argue that fingerprinting simply makes
    DNA identification superfluous, we have no adequate basis for concluding that is
    so. Fingerprinting and DNA identification are not simply substitutes for one
    another. 
    (Robinson, supra
    , 47 Cal.4th at p. 1134.) Fingerprinting alone would not
    have revealed, for example, that there was an outstanding warrant for the
    defendant’s arrest in Robinson. And as the court in King noted, “[i]n considering
    laws to require collecting DNA from arrestees, government agencies around the
    Nation found evidence of numerous cases in which felony arrestees would have
    been identified as violent through DNA identification matching them to previous
    crimes but who later committed additional crimes because such identification was
    not used to detain them.” 
    (King, supra
    , 569 U.S. at p. 454.)
    Defendant also argues that we should reject King as a matter of state
    constitutional law because King “ignored the highly sensitive nature of the genetic
    data contained in the collected DNA,” and “did not address what federal circuit
    37
    courts have recognized as the more significant privacy implications posed by the
    state’s subsequent analysis and retention of the sensitive information contained in
    DNA.” The criticism is misplaced. Contrary to defendant’s characterization, the
    court in King recognized that the privacy interests at stake extended beyond the
    “minimally invasive” physical collection of the DNA sample by buccal swab.
    
    (King, supra
    , 569 U.S. at p. 460.) As noted above, the court acknowledged
    concerns about the genetic information contained in the collected DNA and its
    subsequent analysis. It explained that CODIS testing is designed to reveal nothing
    more about the arrestee than his or her identity, and that state law forbade the use
    of DNA information for nonidentification purposes. (Id. at pp. 464–465.) But the
    court acknowledged that if scientific advances or other developments mean that
    CODIS testing will now lead to discovery of personal medical information, a new
    Fourth Amendment analysis will be required. (Ibid.)
    We, too, are mindful of the heightened privacy interests in the sensitive
    information that can be extracted from a person’s DNA. These interests implicate
    not only article I, section 13, but the privacy rights enjoyed by all Californians
    under the explicit protection of article I, section 1 of the California Constitution.
    (See, e.g., Lewis v. Superior Court (2017) 3 Cal.5th 561, 569.) But our cases have
    also recognized that safeguards against the wrongful use or disclosure of sensitive
    information may minimize the privacy intrusion when the government accesses
    personal information, including sensitive medical information. (E.g., 
    id. at pp.
    576–577 [upholding the constitutionality of government access to prescription
    drug record database under article I, section 1 of the California Constitution].)
    Here, the DNA Act makes the misuse of a DNA sample a felony, punishable by
    years of imprisonment and criminal fines. (Pen. Code, § 299.5.) These strong
    sanctions substantially reduce the likelihood of an unjustified intrusion on the
    suspect’s privacy. Like the King court, we acknowledge the possibility that
    38
    technological change might alter the privacy interests at stake, requiring a new
    constitutional analysis. But we are no more inclined than that court to decide
    cases on the basis of speculation about future developments that may not come to
    pass.
    Defendant next argues that this court should reject King because article I,
    section 13, gives arrested suspects greater privacy rights than they possess under
    the Fourth Amendment. Defendant points to decisions of this court holding that
    article I, section 13 forbids officers from conducting so-called “ ‘accelerated
    booking search[es]’ ” in the field at the time of arrest (People v. Laiwa (1983) 
    34 Cal. 3d 711
    , 726–728); from conducting full body searches of arrested suspects
    before determining whether they will be cited and released without being booked
    (People v. Longwill (1975) 
    14 Cal. 3d 943
    , 951–952 (Longwill)); and from
    conducting searches of personal effects incident to a citation or arrest for a traffic
    violation, absent reason to believe the effects contain weapons or contraband
    
    (Brisendine, supra
    , 13 Cal.3d at pp. 548–552; People v. Norman (1975) 
    14 Cal. 3d 929
    , 938). In the latter cases, we rejected the rule of United States v. 
    Robinson, supra
    , 
    414 U.S. 218
    , which, as we described it in Longwill, permits “full body
    searches of all individuals subjected to custodial arrest,” as well as their effects,
    “regardless of the offense, and regardless of whether the individual is ultimately to
    be incarcerated.” 
    (Longwill, supra
    , 14 Cal.3d at p. 951.)
    But what motivated these decisions was not principally a difference in
    opinion with the federal courts about the scope of legitimate privacy rights of
    persons subject to custodial arrest. California law and federal law alike recognize
    that an arrestee has reduced privacy interests upon being taken into police custody,
    but that reduced privacy interests do not mean zero privacy interests—which is to
    say, “[n]ot every search ‘is acceptable solely because a person is in custody.’ ”
    (Riley v. 
    California, supra
    , 134 S.Ct. at p. 2488, quoting 
    King, supra
    , 569 U.S. at
    39
    p. 463.) Rather, the cases on which defendant relies all turn on a different
    evaluation of legitimate law enforcement needs when arresting suspects in the
    field. As relevant here, this court concluded that the rationales for conducting full
    booking searches before a defendant enters custody do not apply to all persons
    cited or arrested in the field, since “it is factually demonstrable that a substantial
    number of the arrestees will never see the inside of a jail cell.” 
    (Longwill, supra
    ,
    14 Cal.3d at p. 951.) In each case, we explained, “the same factors are operative:
    the potential harm to the officer if the arrestee is armed justifies a limited weapons
    search, but a full booking search is ‘inappropriate in the context of an arrestee who
    will never be subjected to that process.’ ” (Id. at p. 950, quoting 
    Brisendine, supra
    , 13 Cal.3d at p. 547.)
    The question before us, by contrast, does not concern the constitutionality
    of a booking search conducted immediately upon arrest, but a booking search
    conducted at the time of booking, and justified by an interest in accurate
    identification that applies to all persons who are taken into police custody
    following a valid arrest for a serious offense. Cases concluding that full booking
    searches are inappropriate for arrestees who will never be booked into jail are thus
    of limited relevance here.
    Finally, defendant argues that even if the differences between the DNA Act
    and the law at issue in King do not alter the Fourth Amendment analysis, they
    should alter the state constitutional analysis. For reasons already given, these
    differences do not change our assessment of the constitutionality of the DNA Act
    as applied in defendant’s case. Officials asked defendant for a DNA sample upon
    booking, after he was arrested on probable cause for a serious offense, and as he
    was entering pretrial detention. Under the circumstances before us, the
    requirement was not unreasonable.
    40
    IV.
    Our holding today is limited. The sole question before us is whether it was
    reasonable, under either the Fourth Amendment or article I, section 13 of the
    California Constitution, to require the defendant in this case to swab his cheek as
    part of a routine jail booking procedure following a valid arrest for felony arson.
    Because we conclude the requirement was reasonable as applied to defendant, we
    hold he is subject to the statutory penalties prescribed in Penal Code section 298.1.
    Although defendant was arrested on probable cause for felony arson and
    was ultimately convicted of that offense, our dissenting colleagues argue that we
    should reach beyond the facts of the case before us to strike down some or all of
    the DNA Act’s provisions as they apply to other categories of arrestees. They
    argue that we should consider defendant’s reasonable expectations about the use
    and retention of his DNA sample at the time of booking, and we should do so from
    behind a “veil of ignorance,” treating defendant as though his circumstances were
    “indistinguishable” from a suspect who is wrongly or pretextually arrested, or
    against whom charges are never brought, or who is ultimately acquitted of any
    charged offenses. (Dis. opn. of Cuéllar, J., post, at p. 28; see also dis. opn. of Liu,
    J., post, at pp. 1–2.)
    In assessing whether the demand for a sample of an arrestee’s DNA was
    reasonable under article I, section 13, we agree that it may be appropriate to
    consider not only the minimal nature of the physical intrusion associated with a
    buccal swab, but the arrestee’s reasonable expectations about what would happen
    to the sample after collection. But in so analyzing the arrestee’s choice, we cannot
    ignore the safeguards built into the DNA Act: the limited nature of the
    information stored in databases on an arrestee (specifically, a numerical profile
    describing noncoding parts of the arrestee’s DNA); the legal protections against
    possible misuse of the profile or the sample (including felony sanctions for
    41
    knowing improper use or dissemination); and the availability of procedures for
    removing the profile from the database and destroying the sample should the basis
    for the arrestee’s inclusion dissipate. We have no record before us to show that
    these legal protections would have been violated or proved unworkable had
    defendant chosen to comply with the requirement to provide a DNA sample on
    booking. And we note, as a purely practical matter, whatever apprehension
    defendant might have had about the adequacy of the Act’s protections for
    individuals who are found to have been wrongly arrested, for example, would
    certainly have been mitigated by his own knowledge of the circumstances of his
    arrest. (Here, the record shows that defendant knew from the outset that he had
    been apprehended in the act of setting fire to the tires of a police car and
    anticipated that he would be prosecuted for his acts, to which he would later
    confess at trial. (See fn. 4, ante.)) To be sure, as explained above, defendant was
    entitled to the full scope of constitutional protection against unreasonable
    searches, despite his arrest on evident probable cause. And had he later found
    himself in a position to seek expungement of his sample and profile and found the
    statutory procedures inadequate, he would have been entitled to challenge the
    retention of his information on that basis.
    Not all arrestees will be comparably situated to the defendant in this case.
    An individual who, unlike defendant, is arrested in the absence of probable cause
    might reasonably anticipate that charges will never be brought and any attempted
    prosecution will inevitably fail.10 And such an arrestee may, at least in some
    10     Justice Liu (dis. opn., post, at p. 9) invokes language from Florida v.
    Bostick (1991) 
    501 U.S. 429
    , 437–438, which decided a question of detention in
    the context of random police requests to search bus passengers’ luggage. The
    point of the cited passage of Bostick is that a person’s knowledge he or she has
    something to hide does not convert a consensual encounter into a detention. The
    (footnote continued on next page)
    42
    circumstances, have a valid as-applied challenge to the adequacy of the DNA
    Act’s expungement procedures or to application of the Act’s other operative
    provisions, in addition to the other remedies available for unlawful arrest. (Cf.
    People v. 
    McInnis, supra
    , 6 Cal.3d at p. 826 [photograph taken pursuant to an
    illegal arrest could be shown to a witness asked to identify the perpetrator of a
    subsequent crime where there was no evidence the police had “ ‘exploited’ ” the
    earlier illegal arrest].) We note that a group of plaintiffs in federal court have
    already challenged the law’s application to those who are never charged with any
    crime. (See Haskell v. Harris (filed July 18, 2014, N.D.Cal. Civ. Case No. C 09-
    04779 CRB, docket #146), Motion to Create Subclasses, p. 1 [seeking certification
    of subclass consisting of arrestees compelled to submit samples under DNA Act
    “unless they are actually charged with a felony offense”].) We of course take no
    view on the merits of any such challenges. We only note them for purposes of
    contrast with this case, in which defendant bases his challenge to his misdemeanor
    refusal conviction on the potential for constitutional deprivation under
    circumstances that are not, in fact, present here.
    To entertain defendant’s arguments here would convert our decision in this
    case, which concerns only the validity of defendant’s conviction for violation of
    Penal Code section 298.1, into the equivalent of facial constitutional review of the
    DNA Act as it might be applied to other arrestees. But the DNA Act itself
    instructs that the validity of the Act as applied to defendant does not depend on its
    (footnote continued from previous page)
    passage tells us nothing about how to judge the depth of privacy intrusion
    involved in a postarrest demand for a DNA sample based not on the collection of
    the sample itself, but based on the likelihood of future use or retention of the
    sample under various conditions that did not, in fact, obtain in this case.
    43
    validity as it might apply to others. (Prop. 
    69, supra
    , § V, subd. (b); see p. 6,
    ante.) And our jurisprudence likewise counsels us to follow a narrower course.
    While “passing on the validity of a law wholesale may be efficient in the abstract,”
    the law teaches that we should ordinarily focus on the circumstances before us in
    determining whether the work of a coequal branch of government may stand or
    must fall. 
    (Sabri, supra
    , 541 U.S. at p. 609.) We accordingly abide by what has
    been called a “ ‘cardinal principle of judicial restraint—if it is not necessary to
    decide more, it is necessary not to decide more.’ ” (People v. Contreras (2018) 4
    Cal.5th 349, 381.)
    In sum: Defendant raises a number of concerns about the potential
    application of the DNA Act in other cases involving other, differently situated
    arrestees. He also raises concerns that changes in technology might open up new
    prospects for using his DNA samples and profiles in ways that are uniquely
    invasive of personal privacy. We are mindful of these concerns, and we recognize
    that the DNA Act may raise additional constitutional questions that will require
    resolution in other cases.
    In addressing the concerns defendant has raised here, however, we are also
    mindful of our role in reviewing a law duly enacted by California voters in the
    exercise of their initiative power. We have often said that “it is our solemn duty to
    jealously guard” the initiative power secured by the California Constitution, and
    that we accordingly may not strike down voter measures “unless their
    unconstitutionality clearly, positively, and unmistakably appears.” (Legislature v.
    Eu (1991) 
    54 Cal. 3d 492
    , 501.) Whatever else this duty might entail, it surely
    entails an obligation to avoid invalidating the work of the California electorate on
    the ground that “the law would be unconstitutionally applied to different parties
    and different circumstances from those at hand.” 
    (Sabri, supra

    DISSENTING OPINION BY LIU, J.
    According to today’s opinion, “[t]he sole question before us is whether it was
    reasonable, under either the Fourth Amendment or article I, section 13 of the California
    Constitution, to require the defendant in this case to swab his cheek as part of a routine
    jail booking procedure following a valid arrest for felony arson.” (Maj. opn., ante, at
    p. 41, italics added.) This statement of the issue is misleading.
    The DNA Fingerprint, Unsolved Crime and Innocence Protection Act (DNA Act)
    requires collection of DNA from all adult felony arrestees “immediately following arrest”
    and requires samples to be “forwarded immediately” to the laboratory for analysis. (Pen.
    Code, § 295(i)(1)(A), (C).) Buza was arrested on January 21, 2009. At booking a few
    hours later, a police officer requested a cheek swab from Buza under penalty of law.
    Buza refused. It was not until the next day, January 22, 2009, that a judge found
    probable cause to believe Buza committed arson. On January 23, 2009, the district
    attorney filed a complaint charging Buza with arson and related offenses as well as
    unlawful refusal to provide a DNA specimen on January 21, 2009 (id., § 298.1,
    subd. (a)). The question is whether Buza can be convicted of refusing to provide his
    DNA at booking prior to any judicial determination of whether he was validly arrested.
    Today’s opinion does not explain why the fact that Buza was found “validly arrested on
    probable cause to believe he had committed felony arson, and . . . was promptly charged
    with (and ultimately convicted of) that offense” (maj. opn., ante, at p. 15) has any bearing
    on whether it was lawful to require him to provide his DNA before any of those
    determinations were made.
    The court says that a “valid arrest” in this context does not require “a judicial
    determination of its validity.” (Maj. opn., ante, at p. 23.) But this assertion, even if true,
    does not disturb the main premise of the question presented: For purposes of
    constitutional analysis, Buza is no different than any felony arrestee who has not been
    charged, convicted, or found by a neutral magistrate to be lawfully detained. This point
    is critical because it brings into focus the startling breadth of DNA collection and
    retention authorized by the statute. This is not a scheme carefully calibrated to identify
    felony offenders. Instead, it can be fairly described as a biological dragnet. As explained
    below, and for the reasons stated in Justice Cuéllar’s dissent, the DNA Act violates the
    prohibition on unreasonable searches and seizures in the California Constitution.
    According to the Office of the Attorney General, there are 200,000 to 300,000
    felony arrests in California every year. (Cal. Dept. of Justice, Crime in California 2016
    (Aug. 17, 2017) p. 49.) But not all arrests end in convictions; far from it. Here are the
    Attorney General’s data on dispositions of adult felony arrests for each year since 2009,
    when the DNA Act started requiring all such arrestees to provide DNA samples
    immediately upon arrest:

    (Id. at table 37, p. 49.) These data show that from 2009 to 2016, nearly one in five felony
    arrests did not result in prosecution, and almost one in three — a total of 724,492 arrests
    — did not result in a conviction.
    Each of those arrests triggered the requirement to provide a DNA sample. Yet the
    state has no legal basis for retaining the DNA sample or profile if no charges are filed, if
    the charges are dismissed, if the person is acquitted or found not guilty or factually
    innocent, or if the conviction is reversed and the case is dismissed, unless there is some
    other basis such as a prior offense that qualifies the person for inclusion in the state DNA
    database. (Pen. Code, § 299, subds. (a), (b).) The Judicial Council of California,
    pursuant to its reporting obligations under Penal Code section 1170.45, has reported that
    from 2009 to 2016, between 15 and 20 percent of felony arrestees had no criminal record,
    between 14 and 19 percent had one or more prior prison commitments, and around 66
    percent had a criminal record with no prior prison commitment (so-called
    “ ‘miscellaneous’ ” records), a category that presumably includes arrestees with only
    misdemeanor convictions for which DNA collection is not authorized. (See, e.g., Jud.
    Council of Cal., Disposition of Criminal Cases According to the Race and Ethnicity of
    the Defendant (Sept. 20, 2017) p. 15 (Disposition of Criminal Cases) [15 percent of
    felony arrestees in 2016 had no criminal record, 19 percent had one or more prior prison
    commitments, 66 percent had miscellaneous records]; Jud. Council of Cal., Disposition
    of Criminal Cases According to the Race and Ethnicity of the Defendant (2011) [20
    percent of felony arrestees in 2009 had no criminal record, 14 percent had one or more
    prior prison commitments, 66 percent had miscellaneous records].) The percentage of
    felony arrestees with no prior convictions or only misdemeanor convictions is likely
    higher among those who are not charged or not convicted than among felony arrestees
    overall. Thus, even assuming that a substantial portion of the 724,492 arrests from 2009
    to 2016 that resulted in no conviction involved persons with a prior (or subsequent)
    3
    qualifying offense, there are tens if not hundreds of thousands of individuals who have
    been required to provide DNA samples that the state has no legal basis for retaining.
    The statute sets forth a process for expungement, but this process is not adequate
    to allay constitutional concerns. In contrast to the automatic expungement provisions of
    the state law at issue in Maryland v. King (2013) 
    569 U.S. 435
    , 443–444 (King),
    California’s DNA Act provides that a person seeking expungement “must send a copy of
    his or her request to the trial court of the county where the arrest occurred, or that entered
    the conviction or rendered disposition in the case, to the DNA Laboratory of the
    Department of Justice, and to the prosecuting attorney of the county in which he or she
    was arrested or[] convicted[] or adjudicated, with proof of service on all parties.” (Pen.
    Code, § 299, subd. (c)(1).) The Department of Justice “shall destroy” the DNA
    specimen, sample, and searchable profile “upon receipt of a court order that verifies the
    applicant has made the necessary showing at a noticed hearing, and that includes all of
    the following: [¶] (A) The written request for expungement pursuant to this section. [¶]
    (B) A certified copy of the court order reversing and dismissing the conviction or case, or
    a letter from the district attorney certifying that no accusatory pleading has been filed or
    the charges which served as the basis for collecting a DNA specimen and sample have
    been dismissed prior to adjudication by a trier of fact, the defendant has been found
    factually innocent, the defendant has been found not guilty, the defendant has been
    acquitted of the underlying offense, or the underlying conviction has been reversed and
    the case dismissed. [¶] (C) Proof of written notice to the prosecuting attorney and the
    Department of Justice that expungement has been requested. [¶] (D) A court order
    verifying that no retrial or appeal of the case is pending, that it has been at least 180 days
    since the defendant or minor has notified the prosecuting attorney and the Department of
    Justice of the expungement request, and that the court has not received an objection from
    the Department of Justice or the prosecuting attorney.” (Id., subd. (c)(2).)
    4
    The extensive documentation, notice to multiple parties, judicial hearing, and
    additional steps required for expungement place a significant burden on eligible persons,
    assuming they are even aware of the process. In addition, although the statute says a
    person whose arrest resulted in no charge or conviction “shall have his or her DNA
    specimen and sample destroyed and searchable database profile expunged” if the state
    has “no legal basis for retaining” them (Pen. Code, § 299, subd. (a)), the statute also says:
    “The court has the discretion to grant or deny the request for expungement. The denial of
    a request for expungement is a nonappealable order and shall not be reviewed by petition
    for writ.” (Id., § 299, subd. (c)(1).) It is not clear what “discretion” the court may
    exercise in deciding whether to grant or deny a request, or what remedy is available if the
    court denies a valid request. Further, it is not clear what consequence ensues if the state
    does not comply with a court order granting a request for expungement. (Id., § 299,
    subd. (d) [“Any identification, warrant, probable cause to arrest, or arrest based upon a
    databank or database match is not invalidated due to a failure to expunge or a delay in
    expunging records.”].)
    The Department of Justice has sought to expedite the process by creating a
    “Streamlined DNA Expungement Application Form.” (Cal. Dept. of Justice, Proposition
    69 (DNA)  [as of Apr. 2, 2018] [“Remove Your DNA
    Sample from the DNA Database”]; cf. 34 U.S.C. § 12592(d)(2) [requiring states to
    “promptly expunge” the DNA analysis of qualified persons as a condition of state access
    to the DNA index maintained by the FBI].) But the reality is that few DNA samples,
    once collected, are ever removed.
    The Department of Justice DNA Laboratory publishes monthly reports on the
    number of samples added or removed from its inventory as well as historical totals since
    the DNA collection program began in 2004. As of February 2018, the DNA Laboratory
    had received 2,792,083 DNA samples and had removed 44,314 samples, or 1.6 percent,
    since the program began. (Cal. Dept. of Justice, Proposition 69 (DNA)
    5
     [February statistics as of Mar. 28, 2018] [“DNA
    Laboratory Monthly Statistics, pdf”].) As of December 2008, the DNA Laboratory had
    removed 22,269 DNA samples from its inventory since the program began; these
    removals include “Expunged, Removed or Failed Samples, or where a New Sample was
    Requested.” (Appellees’ Response to Appellants’ Request for Judicial Notice;
    Supplemental Request for Judicial Notice and Supporting Declaration of Daniel J.
    Powell, Haskell v. Harris (filed Sept. 20, 2012, 9th Cir. case No. 10-15152) docket #103,
    Ex. A, p. 24; see Haskell v. Harris (9th Cir. 2014) 
    745 F.3d 1269
    (en banc).) Even if we
    assume that all reported removals are expungements, the total number of expungements
    from January 2009, when the current DNA law went into effect, until February 2018
    would be only 22,045 — i.e., the difference between 44,314 (the total number of
    removals through February 2018) and 22,269 (the total number of removals through
    December 2008). This is a small fraction of the large population of individuals since
    2009 whose felony arrests have resulted in no charge or conviction, and who have no
    other basis for inclusion in the state DNA database. It is questionable whether the vast
    majority of people entitled to expungement even know about the process much less know
    how to navigate it. Indeed, we have no indication that any responsible official is ever
    required to inform an arrestee about the expungement process.
    The state’s retention of DNA is troubling not only because of its sheer magnitude
    but also because it predictably burdens certain groups. African Americans, who are 6.5
    percent of California’s population, made up 20.3 percent of adult felony arrestees in
    2016. (U.S. Census Bureau, QuickFacts: California (July 1, 2016)
     [as of Apr. 2, 2018]; Crime in California 
    2016, supra
    , at p. 36.) Yet they comprised 24.3 percent of felony arrestees who were released
    by law enforcement or the prosecuting attorney in 2016 before any court disposition.
    (Disposition of Criminal 
    Cases, supra
    , at p. 10.) Non-Hispanic whites, by contrast,
    comprised 31.2 percent of felony arrestees but only 27.0 percent of felony arrestees
    6
    released by law enforcement or the prosecuting attorney. (Crime in California 
    2016, supra
    , at p. 36; Disposition of Criminal 
    Cases, supra
    , at p. 10.) The fact that felony
    arrests of African Americans disproportionately result in no charges or dropped charges
    means that African Americans are disproportionately represented among the thousands of
    DNA profiles that the state has no legal basis for retaining.
    Penal Code section 297, subdivision (c)(2) provides an alternative route for
    expungement: “The law enforcement investigating agency submitting a specimen,
    sample, or print impression to the DNA Laboratory of the Department of Justice or law
    enforcement crime laboratory pursuant to this section shall inform the Department of
    Justice DNA Laboratory within two years whether the person remains a suspect in a
    criminal investigation. Upon written notification from a law enforcement agency that a
    person is no longer a suspect in a criminal investigation, the Department of Justice DNA
    Laboratory shall remove the suspect sample from its databank files and databases.
    However, any identification, warrant, arrest, or prosecution based upon a databank or
    database match shall not be invalidated or dismissed due to a failure to purge or delay in
    purging records.” But it is not clear how this process, which relies on the initiative of law
    enforcement, is monitored or enforced; the language of the statute, like Penal Code
    section 299, expressly contemplates “failure” or “delay” by responsible officials. In any
    event, this expungement process may take up to two years after a person’s DNA is sent to
    the laboratory, during which time the sample remains available to law enforcement even
    if the person was never charged or convicted of a crime.
    The court says it need not consider the adequacy of the expungement process
    because Buza was “charged with and ultimately convicted of a qualifying crime.” (Maj.
    opn., ante, at p. 28.) But the question is whether it was constitutional to require Buza to
    provide his DNA after his arrest on January 21, 2009 — before he was charged or
    convicted. In answering this question, it certainly matters how his DNA would be
    analyzed, used, and retained, and we must address these considerations from the vantage
    7
    point that existed at the time Buza was required to provide his DNA. (See People v. Gale
    (1973) 
    9 Cal. 3d 788
    , 795 [“ ‘The question of the reasonableness of the officers’ conduct
    is determined on the basis of the information possessed by the officer at the time a
    decision to act is made.’ ”].) We cannot ignore the (in)adequacy of expungement — the
    statute’s only safeguard against overbroad retention — based on the fortuity that Buza
    turned out to be guilty. (See McDonald v. United States (1948) 
    335 U.S. 451
    , 453 [the
    “guarantee of protection against unreasonable searches and seizures extends to the
    innocent and guilty alike”].)
    In addition, the court says collecting DNA from an arrestee before a judge has
    determined the validity of the arrest is analogous to a search incident to arrest, “where a
    valid arrest is also essential [and] there is no such preapproval requirement.” (Maj. opn.,
    ante, at p. 23.) But a search incident to arrest is justified and limited by the immediate
    need to “protect[] arresting officers and safeguard[] any evidence of the offense of arrest
    that an arrestee might conceal or destroy.” (Arizona v. Gant (2009) 
    556 U.S. 332
    , 339.)
    DNA collection upon arrest does not serve any similarly pressing purpose. (Dis. opn. of
    Cuéllar, J., post, at pp. 13–14 [it takes around 30 days to generate an identification profile
    from an arrestee’s DNA sample].) Moreover, when an arrest is later found invalid by a
    neutral magistrate, a search incident to the arrest is deemed unlawful, and the evidence
    obtained is subject to suppression. (See People v. Macabeo (2016) 1 Cal.5th 1206,
    1219.) The DNA Act does not deem unlawful the collection of DNA pursuant to an
    arrest that is later found invalid; such DNA may be retained and used by law enforcement
    so long as there is no request for expungement.
    The court further contends that “whatever apprehension defendant might have had
    about the adequacy of the Act’s protections for individuals who are found to have been
    wrongly arrested, for example, would certainly have been mitigated by his own
    knowledge of the circumstances of his arrest. (Here, the record shows that defendant
    knew from the outset that he had been apprehended in the act of setting fire to the tires of
    8
    a police car and anticipated that he would be prosecuted for his acts, to which he would
    later confess at trial. (See fn. 4, ante.)) . . . . [¶] Not all arrestees will be comparably
    situated to the defendant in this case. An individual who, unlike defendant, is arrested in
    the absence of probable cause might reasonably anticipate that charges will never be
    brought and any attempted prosecution will inevitably fail.” (Maj. opn., ante, at p. 42,
    fn. omitted.) This seems to suggest that arrestees who know they are guilty are entitled to
    lesser constitutional protection than arrestees who believe they are innocent. Such
    reasoning contravenes the fundamental principle that “the ‘reasonable person’ test [in
    search and seizure analysis] presupposes an innocent person. See [Florida v. Royer
    (1983) 
    460 U.S. 491
    , 519, fn. 4] (Blackmun, J., dissenting) (‘The fact that [respondent]
    knew the search was likely to turn up contraband is of course irrelevant; the potential
    intrusiveness of the officers’ conduct must be judged from the viewpoint of an innocent
    person in [his] position’). Accord, [Michigan v. Chesternut (1988) 
    486 U.S. 567
    , 574]
    (‘This “reasonable person” standard . . . ensures that the scope of Fourth Amendment
    protection does not vary with the state of mind of the particular individual being
    approached’).” (Florida v. Bostick (1991) 
    501 U.S. 429
    , 438.) If we are going to make
    the constitutional analysis turn on whether the defendant “knew from the outset” that he
    was guilty, then we might as well dispense with much of seizure and seizure law. (See
    People v. Schmitz (2012) 
    55 Cal. 4th 909
    , 947 (conc. & dis. opn. of Liu, J.) [search and
    seizure doctrine “is built on cases involving guilty people”].)
    I have no doubt that law enforcement is aided by the collection and retention of
    massive numbers of DNA profiles, whether those profiles are used to confirm a person’s
    identity, to facilitate access to criminal history or other information about a person, or to
    help solve unsolved crimes. But if those interests are enough to justify the collection and
    retention of DNA from persons who are arrested but not convicted, not charged, or not
    even found to be lawfully detained so long as they do not seek expungement, then it is
    not that far a step for the state to collect and retain DNA from law-abiding people in
    9
    general, including anyone who “applies for a driver’s license” or “attends a public
    school.” 
    (King, supra
    , 569 U.S. at p. 482 (dis. opn. of Scalia, J.).) Such broad-based
    policies would similarly aid law enforcement while having the virtue of being less
    discriminatory in their effects.
    Indeed, the court’s analogy to fingerprinting, a less invasive and less powerful
    technology, should give us pause. (Maj. opn., ante, at pp. 35–37; see dis. opn. of Cuéllar,
    J., post, at pp. 19–22.) State law already requires individuals to provide a fingerprint in
    order to get a driver’s license (Veh. Code, § 12800, subd. (c)), to become a school teacher
    (Ed. Code, § 44340), to be a professional engineer (Cal. Code Regs., tit. 16, § 420.1), to
    be a practicing attorney (Bus. & Prof. Code, § 6054, subd. (b)), or to join many other
    occupations (id., § 144 [requiring “a full set of fingerprints for purposes of conducting
    criminal history record checks” from applicants to 29 state licensing boards, including
    nurses, pharmacists, physicians, court reporters, funeral directors, guide dog instructors,
    contractors, and accountants]). These requirements serve important public safety and law
    enforcement purposes. But if DNA matching is constitutionally justified by its
    unparalleled efficacy in serving the “ ‘same’ ” identification “ ‘function’ ” as
    fingerprinting (maj. opn., ante, at p. 36, quoting 
    King, supra
    , 569 U.S. at p. 451), then it
    is not clear what constitutional principle stands in the way of requiring a DNA sample in
    every context where the law now requires a fingerprint. (See King, at p. 451 [“the only
    difference between DNA analysis and the accepted use of fingerprint databases is the
    unparalleled accuracy DNA provides”].) One need not be a diehard civil libertarian to
    have serious qualms about where all of this may lead.
    I conclude with a few words about the court’s approach to state constitutional
    analysis against the backdrop of King. Today’s opinion affirms that “the California
    Constitution is, and has always been, ‘a document of independent force’ [citation] that
    sets forth rights that are in no way ‘dependent on those guaranteed by the United States
    10
    Constitution’ (Cal. Const., art. I, § 24).” (Maj. opn., ante, at p. 30.) And the court is
    correct that “although decisions of the United States Supreme Court interpreting parallel
    federal text are not binding, we have said they are ‘entitled to respectful consideration.’ ”
    (Id. at p. 31.) But the court errs in framing the inquiry as “whether adequate reasons are
    present here to conclude, despite King,” that the DNA Act is unconstitutional. (Id. at
    p. 34.) In analyzing the state constitutional issue, the court takes King as the starting
    point and asks “whether we should reject the high court’s Fourth Amendment guidance.”
    (Id. at pp. 33–34, fn. omitted.) In so doing, the court appears to accord King “a
    presumption of correctness that has no sound basis in our federal system.” (Liu, State
    Constitutions and the Protection of Individual Rights: A Reappraisal (2017) 92 N.Y.U.
    L.Rev. 1307, 1314.)
    “Just as the Supreme Court, when interpreting a provision of the Federal
    Constitution, does not accord a presumption of correctness to any state’s interpretation of
    an analogous state constitutional provision or even to an interpretation adopted by a
    majority of states, there is no reason why a state court, when interpreting a provision of
    its state constitution, should accord a presumption of correctness to the Supreme Court’s
    interpretation of an analogous federal constitutional provision. State courts should and
    often do give respectful consideration to relevant Supreme Court decisions, just as they
    often give respectful consideration to relevant decisions of sister states. And state courts
    may often be persuaded that the Supreme Court’s approach is correct and worthy of
    adoption, just as they may often be persuaded by a majority view among state high
    courts. But the crucial point is that state courts, as the ultimate arbiters of state law, have
    the prerogative and duty to interpret their state constitutions independently.” 
    (Liu, supra
    ,
    92 N.Y.U. L.Rev. at pp. 1314–1315.)
    As Justice Cuéllar notes, today’s opinion provides no convincing rationale for why
    our analytical approach to a state constitutional issue should depend on “the order in
    which this court decides an issue vis-à-vis the high court.” (Dis. opn. of Cuéllar, J., post,
    11
    at p. 8.) The court’s response is that “in instances where this court had previously
    decided an issue, that decision carried the persuasive force of stare decisis we always
    accord our own precedents, which had then to be balanced against the persuasive force of
    the contrary United States Supreme Court decision. In instances where we had not
    previously decided an issue, no similar counterbalance existed.” (Maj. opn., ante, at
    p. 34, fn. 9.) But this statement of the obvious misses the point. It does not explain why
    our approach should be different (1) when we consider a state constitutional issue of first
    impression on which the high court has spoken under federal law, as compared to (2)
    when we consider a state constitutional issue of first impression on which the high court
    has not spoken under federal law. To be sure, in scenario (1) we should give respectful
    consideration to the views of the high court, as well as the views of other state courts that
    have decided the issue under their states’ laws. But our duty to interpret the California
    Constitution independently is no different in scenario (1) than in scenario (2). We may
    decide, in our independent judgment, that the views of the high court should be followed.
    But that is different from the mode of analysis in today’s opinion, which accords a
    presumption of correctness to the high court’s decision in King and then asks whether
    there are “sufficient reasons” to depart from King. (Id. at p. 32, fn. 8.)
    Moreover, the court fundamentally missteps in attributing its deferential reading of
    King to “ ‘the fact that to [the high court] has been committed, by the consent of the
    states, the ultimate vindication of liberty and property against arbitrary and
    unconstitutional state legislation.’ ” (Maj. opn., ante, at p. 31.) It is of course true that
    the United States Supreme Court serves as a backstop against state infringements on
    constitutional rights, and when the high court issues a federal constitutional ruling, state
    courts “shall be bound thereby, any Thing in the Constitution or Laws of any State to the
    Contrary notwithstanding.” (U.S. Const., art. VI, cl. 2.) But that is not a reason for state
    courts to treat the floor of constitutional rights under federal law as a presumptive ceiling
    on constitutional rights under state law. Doing so runs counter to the basic precept that
    12
    “ ‘ “federalism secures to citizens the liberties that derive from the diffusion of sovereign
    power.” ’ ” (Bond v. United States (2011) 
    564 U.S. 211
    , 221.) “The Framers concluded
    that allocation of powers between the National Government and the States enhances
    freedom” (ibid.), and a crucial feature of this freedom-enhancing allocation of powers is
    judicial federalism: “state courts no less than federal are and ought to be the guardians of
    our liberties” (Brennan, State Constitutions and the Protection of Individual Rights
    (1977) 90 Harv. L.Rev. 489, 491). “State courts interpreting state law remain particularly
    well situated to enforce individual rights against the States. Institutional constraints, it
    has been observed, may limit the ability of [the United States Supreme] Court to enforce
    the federal constitutional guarantees. Sager, Fair Measure: The Legal Status of
    Underenforced Constitutional Norms, 91 Harv.L.Rev. 1212, 1217–1218 (1978). Prime
    among the institutional constraints, [the United States Supreme] Court is reluctant to
    intrude too deeply into areas traditionally regulated by the States. This aspect of
    federalism does not touch or concern state courts interpreting state law.” (Arizona v.
    Evans (1995) 
    514 U.S. 1
    , 30–31 (dis. opn. of Ginsburg, J.).) I do not see how deferring
    to high court decisions under federal law when we construe parallel provisions of state
    law serves the basic purposes of federalism, and the court has no answer on this point.
    Notwithstanding today’s opinion, this court is no stranger to the importance of
    judicial federalism. In People v. Cahan (1955) 
    44 Cal. 2d 434
    , we adopted the
    exclusionary rule for violations of the state constitutional prohibition on unreasonable
    searches and seizures, declining to follow the high court’s refusal to adopt a federal
    exclusionary rule in Wolf v. Colorado (1949) 
    338 U.S. 25
    . In People v. Wheeler (1978)
    
    22 Cal. 3d 258
    , we held that a prosecutor’s exercise of a racially motivated peremptory
    strike in an individual case violates the state constitutional right to be tried by a fair and
    impartial jury, declining to follow the contrary federal constitutional rule set forth in
    Swain v. Alabama (1965) 
    380 U.S. 202
    . And in In re Marriage Cases (2008) 
    43 Cal. 4th 757
    , we held that laws denying same-sex couples the right to marry violate equal
    13
    protection under the state constitution, even though the only high court authority on point
    at the time, Baker v. Nelson (1972) 
    409 U.S. 810
    , had dismissed a similar appeal for want
    of a substantial federal question.
    In each of these instances, we interpreted the guarantees of our state constitution
    without according any deference or presumption of correctness to high court precedent.
    And on each of these issues, the high court eventually overruled its precedent and
    adopted as a matter of federal law the rule we had adopted as a matter of state law. (See
    Mapp v. Ohio (1961) 
    367 U.S. 643
    , 651–653 [overruling Wolf and citing Cahan]; Batson
    v. Kentucky (1986) 
    476 U.S. 79
    , 82–82 & fn. 1 (1986) [overruling Swain and citing
    Wheeler]; Obergefell v. Hodges (2015) 576 U.S. __, __, __ [
    135 S. Ct. 2584
    , 2605, 2610]
    [overruling Baker and citing In re Marriage Cases].) These examples show how the
    exercise of independent judgment by state courts in our system of judicial federalism
    provides a crucial safeguard for constitutional rights.
    Instead of looking to these examples, today’s opinion cites Gabrielli v.
    Knickerbocker (1938) 
    12 Cal. 2d 85
    , which rejected a state constitutional challenge to a
    law requiring schoolchildren to salute and pledge allegiance to the flag. (Maj. opn., ante,
    at p. 31.) I would not rely on such dubious precedent. Whatever may be said about the
    merits of the issue, the court’s analysis in Gabrielli consists of little more than uncritical
    acceptance of United States Supreme Court decisions that had rejected similar claims
    under the federal Constitution. (See Gabrielli, at p. 89 [“[C]ogent reasons must exist
    before a state court in construing a provision of the state Constitution will depart from the
    construction placed by the Supreme Court of the United States on a similar provision in
    the federal Constitution.”], quoted in maj. opn., ante, at p. 31.) Five years later, the high
    court overruled its precedent and decided the issue the other way in West Virginia State
    Board of Education v. Barnette (1943) 
    319 U.S. 624
    .
    In sum, we should not indulge any suggestion that the job of protecting individual
    rights in our federal system belongs primarily to the United States Supreme Court or that
    14
    the high court is invariably better positioned than state supreme courts to discharge that
    critical function. Because I do not agree with the court’s analysis of the state
    constitutional question presented or its judgment upholding Buza’s conviction for
    refusing to provide a DNA sample just hours after his arrest, I respectfully dissent.
    Having concluded that Buza’s conviction for refusing to comply with the DNA Act is
    invalid under the California Constitution, I express no view on whether it is also invalid
    under the Fourth Amendment.

    DISSENTING OPINION BY CUÉLLAR, J.
    In California people are protected not only by federal constitutional guarantees
    against unreasonable searches or seizures, but by state constitutional provisions
    governing privacy and prohibiting arbitrary coercion. These protections require
    courts to distinguish between routine lawful procedures, such as those governing
    collection of biological samples from convicts, and arbitrary commands purporting to
    force people who have not been convicted of anything to surrender their most private
    information. (See Riley v. California (2014) 573 U.S. ___, ___ [
    134 S. Ct. 2473
    ,
    2488] (Riley) [“Not every search ‘is acceptable solely because a person is in
    custody.’ ”]; White v. Davis (1975) 
    13 Cal. 3d 757
    , 766 (White) [“The inherent
    legitimacy of the police ‘intelligence gathering’ function does not grant the police the
    unbridled power to pursue that function by any and all means. In this realm, as in all
    others, the permissible limits of governmental action are circumscribed by the federal
    Bill of Rights and the comparable protections of our state Constitution.”].) Yet the
    majority today sanctions the collection and analysis of DNA samples from all adults
    arrested on felony charges –– fully one-third of all arrestees –– regardless of whether
    those individuals will ever be charged with a crime or, if charged, ever convicted. As
    Justice Liu explains in more detail, over half of these individuals are released before a
    judicial determination of probable cause. But at whatever point the arrestees are
    released, their DNA sample stays with the government until the expungement process,
    which burdens individuals and is contingent rather than automatic, runs its course if it
    ever does.
    For all these individuals, the majority provides no protection –– except to
    say that if they are exonerated, they may file written requests for the expungement
    of their DNA records. In so holding, the majority sidesteps the problems
    associated with the collection and expungement procedures of Proposition 69, the
    DNA Fingerprint, Unsolved Crime and Innocence Protection Act (DNA Act or the
    Act). It contends that the scope of the legitimate privacy rights of persons arrested
    is no different under our constitution than under the Fourth Amendment to the
    federal Constitution and, by implication, that our own constitution plays no role in
    determining whether the rights of a California citizen subjected to a search of his
    person and collection of his DNA have been violated. I cannot agree.
    Our state Constitution provides heightened protections for the privacy
    rights of individuals, including arrestees. Those protections do not vanish merely
    because someone is arrested. An arrest itself requires probable cause –– but such
    cause, however probable, is a far cry from a conviction. Indeed, the underlying
    logic of our system of criminal investigation and enforcement is grounded in the
    distinction between the relatively low-threshold probable cause determination and
    the onerous burden the government must carry to achieve a criminal conviction.
    The government may justify a variety of investigative activities without probable
    cause –– from routine patrol of a particular geographic location to following up on
    tips or information from undercover agents. (E.g., Kyllo v. United States (2001)
    
    533 U.S. 27
    , 31–32 (Kyllo) [reiterating the “lawfulness of warrantless visual
    surveillance of a home”]; Illinois v. Gates (1983) 
    462 U.S. 213
    , 227, 243 [holding
    that a tip alone did not supply probable cause but the police follow-up
    investigation of the tip did].) But when the Act compels the collection of a DNA
    sample before a determination of probable cause, the government’s rationale for
    seeking DNA samples for all felony arrestees is not sufficiently compelling to
    outweigh the intrusion on an arrestee’s privacy that accompanies the collection
    2
    and storage of his personal genetic information. Though the United States
    Supreme Court may have reached a different conclusion when evaluating another
    state’s DNA collection statute under the federal Constitution, the role of our state
    charter, the unique importance it assigns to privacy, and the differences between
    the statute considered in Maryland v. King (2013) 
    569 U.S. 435
    (King) and the
    DNA Act involved here all suggest that we should find the implicated provisions
    of the Act unconstitutional. So I respectfully dissent.
    I.
    What the parties in this case have asked us to decide is whether the DNA
    Act’s provisions requiring collection from all adult felony arrestees violate article
    I, section 13 of the California Constitution. So we begin by considering our state
    Constitution, its relationship to the federal charter, and where the two diverge.
    Construing a different statute and a different constitution, the high court in
    King decided that the Fourth Amendment permits — in some instances —
    collections of DNA from adults arrested for serious crimes. 
    (King, supra
    , 569
    U.S. at p. 446.) Although such a decision merits “respectful consideration” when
    its analysis is relevant, our own constitution deserves far more than that. In
    deciding whether our own state Constitution provides protection against the search
    or seizure at issue, we are not only free, but obligated, to perform an independent
    analysis. (People v. Teresinski (1982) 
    30 Cal. 3d 822
    , 835–836 (Teresinski)
    [“[T]he California courts, in interpreting the Constitution of this state, are not
    bound by federal precedent construing the parallel federal text. . . . [T]he state
    courts, in interpreting constitutional guarantees contained in state constitutions, are
    independently responsible for safeguarding the rights of their citizens.” (internal
    quotation marks omitted)].) Because of our precedent interpreting the scope of
    article I, section 13 and the relevance of article I, section 1’s explicit protection of
    3
    privacy, our constitution is more solicitous of the privacy interests of arrestees
    than the Fourth Amendment.
    The California Constitution is not some minor codicil to the United States
    Constitution. As the majority has no choice but to acknowledge (maj. opn., ante,
    at pp. 30–31), our state Constitution is a document of “independent force,” whose
    meaning is to be independently distilled and propagated by this court, acting in our
    authority as the state court of last resort. (Cal. Const., art. I, § 24 [making explicit
    that “[r]ights guaranteed by this Constitution are not dependent on those
    guaranteed by the United States Constitution”]; People v. Brisendine (1975) 
    13 Cal. 3d 528
    , 549–550 (Brisendine) [“the California Constitution is, and always has
    been, a document of independent force”]; People v. Longwill (1975) 
    14 Cal. 3d 943
    , 951, fn. 4 (Longwill) [stating that “in the area of fundamental civil liberties,”
    “we sit as a court of last resort” and “our first referent is California law and the
    full panoply of rights Californians have come to expect as their due”].) In cases
    where the wording of the state constitutional provision at issue parallels a phrase
    in the federal Constitution, high court opinions on the subject merit respectful
    consideration. 
    (Teresinski, supra
    , 30 Cal.3d at p. 835.) But any such parallels in
    wording must not occlude our state Constitution’s force as the basic charter of
    government, which is why it is appropriate in some circumstances to take a
    different course in interpreting our state Constitution. (Ibid.)
    We have done so in a variety of cases, where we concluded that
    California’s Constitution extends protections to our citizens well beyond those the
    high court has announced in the federal context. (Raven v. Deukmejian (1990) 
    52 Cal. 3d 336

    What’s more, within the specific context of search and seizure of arrestees,
    we have been quite explicit in holding that article I, section 13 provides greater
    protection than does the Fourth Amendment. 
    (Brisendine, supra
    , 13 Cal.3d at pp.
    545–546; 
    Longwill, supra
    , 14 Cal.3d at p. 951 & fn. 4; People v. Norman (1975)

    , 9–11
    (Ruggles); see also People v. Laiwa (1983) 
    34 Cal. 3d 711
    , 727 (Laiwa).) In those
    cases, we have emphasized that article I, section 13 “requires a more exacting
    standard” for search and seizure cases arising in this state. 
    (Brisendine, supra
    , 13
    Cal.3d at p. 545.) We’ve also rejected the notion — which the United States
    Supreme Court has embraced — that an individual subject to custodial arrest has
    significantly diminished expectations of privacy. (Id. at p. 547 [“we cannot accept
    . . . that ‘an individual lawfully subjected to a custodial arrest retains no significant
    Fourth Amendment interest in the privacy of his person’ ”].) Even full custodial
    arrest, booking, and incarceration do not authorize the police to search an arrestee
    5
    in the hope of discovering evidence of a more serious crime. (See 
    Laiwa, supra
    ,
    34 Cal.3d at pp. 727–728.) What these authorities make clear is as simple as it is
    important: individuals placed under arrest enjoy greater protection against
    searches of their persons and things under our state Constitution than under the
    federal counterpart.
    The majority wisely avoids debating such principles. Instead, it seeks to
    limit relevance of cases like Brisendine, Longwill, Norman, and Laiwa by
    asserting that they all concern “the constitutionality of a [field] search conducted
    immediately upon arrest,” and not, as was the case with petitioner Mark Buza, a
    search “conducted at the time of booking.” (See maj. opn., ante, at p. 40.) Yet it is
    far from clear why it should matter that these authorities concern searches done in
    the field. We have not previously imposed limitations on the scope of the
    constitutional protections involved that would categorically cleave the rights of
    individuals subject to searches in the field from those being compelled to provide
    their DNA at the time of booking. And existing distinctions do not detract from
    the fact that — in some circumstances — California residents have more robust
    rights than equivalent ones available under the federal Constitution. 
    (Brisendine, supra
    , 13 Cal.3d at pp. 550–551 [“in determining that California citizens are
    entitled to greater protection under the California Constitution against
    unreasonable searches and seizures than that required by the United States
    Constitution, we are embarking on no revolutionary course”].) The question
    facing us is whether we should extend the same greater protection to our citizens
    in this situation, not whether we have done that exact thing before.1
    1      I would also note that the DNA Act authorizes cheek swabs “immediately
    following arrest” and thus encompasses field searches. (Pen. Code § 296.1,
    subd. (a)(1)(A).)
    6
    The majority suggests that we should not do so because the United States
    Supreme Court decided King before we considered the issue. It implies that if the
    Supreme Court “had not yet decided the parallel question under the Fourth
    Amendment,” then we may be empowered to reach our own conclusions. (Maj.
    opn., ante, at p. 33.) But because King predated our consideration, our
    responsibility shifts from deciding the legality of the search under article I, Section
    13 to determining whether “we should reject the high court’s Fourth Amendment
    guidance.” (Id. at pp. 33–34.)
    Nowhere in the majority opinion is there a persuasive justification for why
    the question is framed in terms of whether we should “reject” the United States
    Supreme Court’s “guidance.” Of course we consider United States Supreme Court
    decisions when they address the scope of a federal constitutional right analogous
    to a state right, even if we are not required on federal supremacy grounds to adopt
    the same approach. But unlike the majority, we treat our own precedent as worthy
    of –– at least –– “meaningful and careful consideration” as well. (Maj. opn., ante,
    at p. 32, fn. 8.) Our precedent makes clear that even where the relevant provision
    under our state charter shares “language [in] common” with the federal
    Constitution, we may interpret our constitution differently than how the high court
    reads the federal Constitution. (See Am. Acad. of Pediatrics v. Lungren (1997) 
    16 Cal. 4th 307
    , 326 (Lungren) [“even when the terms of the California Constitution
    are textually identical to those of the federal Constitution, the proper interpretation
    of the state constitutional provision is not invariably identical to the federal courts’
    interpretation of the corresponding provision contained in the federal
    Constitution”].) What’s more, we have said the particular provision at stake here
    — article I, section 13 — affords arrestees more expansive protection than does
    the Fourth Amendment. The majority relegates our decisions to the sideline in its
    rush to adhere to what it calls the high court’s “guidance,” but in fact, treats as
    7
    controlling authority. In doing so, the majority fails to maintain fidelity to our
    caselaw and Constitution.
    The position the majority takes is in tension even with its own logic. There
    is simply no good reason to believe that the order in which this court decides an
    issue vis-à-vis the high court should determine the outcome of our deliberation, or
    that we should read our prior cases as supporting some kind of ersatz presumption
    that we should ration as much as possible the discussion of state constitutional
    rights. The framing is inconsistent with the majority’s purported “reaffirm[ation]”
    of “long-established principles” that the rights guaranteed by our state Constitution
    “are in no way ‘dependent on those guaranteed by the United States
    Constitution.’ ” (Maj. opn., ante, at p. 30.) If the rights of our citizens are not
    dependent on the federal Constitution, then our analytical route for determining
    what those rights are should not take a different course simply because the United
    States Supreme Court issued an opinion before we did.
    In replying to our criticism, the majority seeks its answer to the awkward
    question of why temporal order matters so much for its analysis in a rationale that
    it describes as “straightforward” — so straightforward, in fact, it may be captured
    in two words: “stare decisis.” (Maj. opn., ante, at p. 34, fn. 9.) When we have
    not spoken, says the majority, the weight of stare decisis does not exist to
    counterbalance against the “force of the contrary United States Supreme Court
    decision.” (Ibid.) This contention is doubly flawed. First, by positing that
    California courts have not spoken, the majority wrongly implies that nothing in
    our own precedent weighs as much as even a single federal court decision that’s
    not binding on us. Yet as detailed in this section, any reasonable reading of our
    past decisions reveals them to be enormously relevant to the question before us.
    Second, how the majority decides to frame its inquiry is just as much a
    problem. By asking whether we may grant our own courts a permission slip to
    8
    “depart” from a United States Supreme Court decision addressing a matter that is
    no more than partially similar to the case before us, the majority has done more
    than to adjust the weight on the state side of the jurisprudential scale relative to the
    federal side. It’s dispensing with the scale altogether. Instead of weighing the
    relative merits of the issue at hand according to our independent responsibility to
    construe our Constitution, the majority appears to deploy words like “depart” and
    “guidance” to embrace the view that we should presumptively comply with a
    United States Supreme Court opinion that does not even address the precise
    question before us. In this new analysis, our own authorities are emaciated in
    importance by being read narrowly, such that booking searches are presumed to be
    so categorically distinct from field searches that nothing meaningful can be
    gleaned for this case from decisions involving the latter. Meanwhile, a far-broader
    reading and presumption of validity is reserved for a non-binding United States
    Supreme Court decision — even though the decision is interpreting a different
    Constitution, and a different DNA collection scheme that does not come close to
    applying to all felony arrestees. This position implies that the United States
    Supreme Court can dictate what we do whenever we interpret an issue under the
    California Constitution, despite our prior decisions supporting a contrary answer,
    so long as we have not previously resolved precisely the same question.
    Remarkably, this position removes both the “stare” and “decisis” from “stare
    decisis” –– inverting the concept to justify departures from California decisions
    governing the scope of state privacy protection.
    Those decisions underscore how adopting King’s approach would be at
    odds with article I, section 1 of California’s Constitution. And it would be at odds
    with our case law construing that provision and emphasizing the importance of
    informational and dignitary privacy interests under California law. In contrast to
    its federal counterpart, the California Constitution contains an express statement
    9
    about the importance of personal privacy: “All people are by nature free and
    independent and have inalienable rights. Among these are enjoying and defending
    life and liberty, acquiring, possessing, and protecting property, and pursuing and
    obtaining safety, happiness, and privacy.” (Cal. Const., art. I § 1.) True: we have
    previously found that article I, section 1 does not by itself confer a privacy right
    substantively different from what article I, section 13 purports to protect. (People
    v. Crowson (1983) 
    33 Cal. 3d 623
    , 629.) But neither have we held that this
    language is devoid of meaning when considered together with that of article I,
    section 13.
    The reason we have not so held is because the most sensible reading of the
    California Constitution would assign both importance and meaning to its mention
    of personal privacy. Even if the language in article I does not create a separate
    class of privacy rights, at a minimum this reference underscores how certain
    infringements of personal privacy deserve heightened scrutiny in our search and
    seizure analysis relative to what the federal analysis requires. Our cases
    construing article I, section 1 in relation to the federal Constitution reinforce this
    conclusion. What we have emphasized is that the scope of the state constitutional
    right of privacy is broader than the concept of privacy the federal courts have
    identified — and that this distinction may at times lead us to provide greater
    protection for individuals’ privacy rights than the federal courts might. 
    (Lungren, supra
    , 16 Cal.4th at pp. 326–327 [“past California cases establish that, in many
    contexts, the scope and application of the state constitutional right of privacy is
    broader and more protective of privacy than the federal constitutional right of
    privacy as interpreted by the federal courts”].)
    Our cases have described the “core value” of article I, section 1 as
    protecting so-called “informational privacy,” meaning the privacy interest in
    sensitive and confidential personal information. (Hill v. National Collegiate
    10
    Athletic Assn. (1994) 
    7 Cal. 4th 1
    , 35–36 (Hill); 
    Lungren, supra
    , 16 Cal.4th at p.
    406.) We have found that article I, section 1 grew out of the electorate’s fears of
    “increased surveillance and data collection activity in contemporary society”
    
    (White, supra
    , 13 Cal.3d at p. 774), and was intended to address the potential
    collection, stockpiling, and use of individuals’ most personal information in an
    arbitrary and unjustified fashion. (Ballot Pamp., Gen. Elec. (Nov. 7, 1972)
    argument in favor of Prop. 11, p. 27 (Article I, section 1 Ballot Pamp.) [privacy
    initiative targeted the “collecting and stockpiling [of] unnecessary information . . .
    and misusing information gathered for one purpose in order to serve other
    purposes or to embarrass”].) Article I, section 1 provides special protection for
    what we have deemed “autonomy,” or dignitary, privacy, which we have
    described as protecting the interest in making “personal decisions or conducting
    personal activities without observation, intrusion, or interference.” 
    (Hill, supra
    , 7
    Cal.4th at p. 35.) We have found dignitary privacy to embrace a person’s interest
    in retaining control over his or her own body and “bodily integrity.” 
    (Lungren, supra
    , 16 Cal.4th at pp. 326–327, 337.) Finally, it has not escaped our attention
    that article I, section 1 addresses the unique harms that can occur when the
    government intrudes on a person’s privacy. The proponents of the provision
    warned of the possibility of the government assembling “personal information”
    and referred specifically to the possibility that private information could be
    permanently stored in government records. (Article I, section 1 Ballot 
    Pamp., supra
    , at p. 26 [“Government agencies seem to be competing to compile the most
    extensive sets of dossiers of American citizens. Computerization of records makes
    it possible to create ‘cradle-to-grave’ profiles of every American.”].)
    Given the nature of these concerns, the machinery of the DNA Act appears
    to epitomize the sort of intrusion relevant under article I, section 1. The collection
    of DNA — whether it is via cheek swab or any of the other collection processes
    11
    the Act permits (see Pen. Code, § 298.1, subd. (b) [permitting the use of
    reasonable force to collect DNA database samples]) — violates the subject’s
    bodily integrity. (See 
    Hill, supra
    , 7 Cal.4th at pp. 40–41 [finding that the
    collection of a urine sample “impacts legally protected privacy interests”].) And
    the use of that sample to create and store a DNA profile gives the government
    long-term access to the subject’s genetic code — some of the most personal
    information imaginable. (Id. at p. 41 [“ ‘A person’s medical profile [as revealed
    by the collection and analysis of urine] is an area of privacy infinitely more
    intimate, more personal in quality and nature than many areas already judicially
    recognized and protected.’ ”]; Birchfield v. North Dakota (2016) 579 U.S. ___,
    ___–___ [
    136 S. Ct. 2160
    , 2177] (Birchfield) [noting that DNA collection and
    analysis “put into the possession of law enforcement authorities a sample from
    which a wealth of additional, highly personal information could potentially be
    obtained”].) The DNA Act’s processes thus seem to fall close to the heart of
    article I, section 1’s scope. Consequently, it is vital to consider article I, section 1
    in our independent analysis of the constitutionality of the DNA Act under our state
    charter.
    Ultimately, the majority’s approach to constitutional federalism fails to do
    justice to the importance of state constitutional rights. The majority does not
    appear to reject the well-settled principle that “[t]he construction of a provision of
    the California Constitution remains a matter of California law regardless of the
    narrower manner in which decisions of the United States Supreme Court may
    interpret provisions of the federal Constitution.” (People v. Pettingill (1978) 
    21 Cal. 3d 231
    , 247–248.) Yet it ironically finds that neither our constitution nor case
    law offers “adequate reasons” for us to take a fresh look at this case beyond what
    it takes to be the long shadow cast by King. (Maj. opn., ante, at p. 34.)
    12
    The path we are bound to follow is a different one. Instead of relying
    primarily on King to yield a tidy solution in this case, we owe it to the citizens of
    our state to perform an independent analysis to determine whether “ ‘the particular
    governmental invasion of a citizen’s personal security’ ” is reasonable under the
    circumstances of this case. (In re Tony C. (1978) 
    21 Cal. 3d 888
    , 892.) Our
    analysis shows the intrusion to be unreasonable.
    II.
    Once we assign proper weight and meaning to the California Constitution,
    we can turn to the ultimate question in any case arising under article I, section 13:
    whether the search or seizure in question is reasonable. (Ingersoll v.
    Palmer (1987) 
    43 Cal. 3d 1321
    , 1329 (Ingersoll); see also 
    Brisendine, supra
    , 13
    Cal.3d at p. 536.) At issue here is the compelled physical production of a
    biological sample from someone who has not been convicted. Whether this
    particular search satisfies the reasonableness standard is judged by balancing its
    intrusion on the individual’s reasonable expectations of privacy against its
    promotion of legitimate government interests. (People v. Robinson (2010) 
    47 Cal. 4th 1104
    , 1120 (Robinson).) In this section, we examine the interests the
    government says are served by the DNA Act. Ultimately, such interests either
    ring hollow or prove insufficient to justify suspicionless, warrantless searches of
    the type allowed by the Act.
    As a threshold matter, it is questionable whether the DNA Act genuinely
    furthers many of the interests the government identifies. The government must
    create a DNA profile and compare it against existing profiles to obtain any of the
    “identification” information it needs. The State informs us here that it takes
    “around 30 days on average” to generate an identification profile from an
    arrestee’s DNA sample. Yet in seeking to justify the collection of DNA, the
    government points to functions — verifying identity, making bail decisions, and
    13
    so forth — that it must perform near to the time an arrestee is booked and
    processed into jail, or shortly thereafter. In fact, the Attorney General
    acknowledges that “in many cases” an arrestee is released from custody before the
    State obtains his or her DNA profile. So, it seems unlikely that DNA collection
    actually furthers any of these identification interests; the government even
    acknowledges that it uses fingerprints, not DNA, to aid most of these decisions
    and that fingerprinting “plays the lead role in confirming who a person is.” Law
    enforcement officials are able to collect fingerprints promptly, compare them
    against an electronic database composed of prints from various sources —
    including former arrestees but also civil sources such as persons who have served
    or are serving in the United States military, or have been or are employed by the
    federal government — and obtain a response as to any “hits” within approximately
    27 minutes. (FBI, Integrated Automated Fingerprint Identification System
    archived at
     [as of Apr. 2, 2018].) In short, it seems
    that DNA collection does little to meaningfully further the State’s asserted
    interests in establishing an arrestee’s identity and making various intake and
    processing decisions.
    The majority acknowledges that there may be a delay of “weeks or months”
    between the initial booking and when a DNA profile is generated. (Maj. opn.,
    ante, at pp. 36–37.) Nonetheless, it asserts that governmental interest in
    identifying arrestees is unaffected because information from an DNA profile —
    late as it may be in coming in — can still “influence the jailer’s decision about
    where to house the arrestee,” or lead to a “revisit [of] an initial determination to
    release the arrestee” or “impos[ition] [of] new release conditions.” (Id. at p. 36.)
    The government did not advance interests so far removed from the time of
    14
    booking in its own briefs. Tellingly, the majority has cited no source to suggest
    that jails have the capacity to rehouse felony arrestees — those arrested for
    “serious or violent” crimes (
    id. at p.
    17) — in more secured places simply because
    they are now suspected of a second crime, as revealed by a “hit” against their
    DNA profile. We also question the premise that a reassessment of the initial
    release decision is in itself a compelling governmental interest, especially when
    we have little idea — as neither the government nor the majority has told us —
    how often such a circumstance presents itself. We are asked to tip the scale in
    favor of the government without knowing how many felony arrestees are released;
    released with less than a full set of conditions imposed; or face a revisit of the
    initial release determination when their DNA generates a hit (as opposed to an
    arrest on the new crime). To expect that we would simply look past this absence
    of justification is to take the idea of a blindfold on the judicial process far too
    literally. (See 
    Riley, supra
    , 134 S.Ct. at p. 2485 [finding an asserted government
    interest inadequate when “neither the United States nor California offers evidence
    to suggest that their concerns are based on actual experience”].)
    Instead of the supposed interests tied to the initial arrest and booking, the
    most plausible justification for the present DNA collection is that it aids in
    identifying arrestees who may have been perpetrators of unsolved crimes.
    Proposition 69 was titled the “DNA Fingerprint, Unsolved Crime and Innocence
    Protection Act.” Ballot arguments in favor of the initiative relied heavily on the
    promise that DNA collection would increase the likelihood of solving cold cases
    and help police investigations. (See Ballot Pamp., Gen. Elec. (Nov. 2, 2004)
    argument in favor of Prop. 69.) For instance, those arguments referenced a
    number of murders that had been solved based in part on DNA evidence and
    promised that the DNA Act would help “solve crime, free those wrongfully
    accused, and stop serial killers.” (Ballot Pamp., Gen. Elec. (Nov. 2, 2004) text of
    15
    Prop. 69, p. 62.) Likewise, the findings section of the proposed law declared that
    it would “solve crime[s],” “apprehend perpetrators,” expand the number of “cold
    hits and criminal investigation links,” and thereby “substantially reduce the
    number of unsolved crimes.” (Id. at p. 135.)
    The Attorney General’s arguments in defense of the DNA Act suffer
    essentially the same malady. Most of the government’s justifications for the DNA
    Act that the Attorney General emphasizes — even those couched in terms of
    “identity” — pivot on generalized concerns about crime-solving. For instance, the
    Attorney General argues that since the DNA Act was enacted, the State has
    recorded more than 31,000 “hits” between identification profiles taken from
    arrestees and DNA stored from unsolved cases. The government argues that DNA
    identification yields “substantial benefits” for law enforcement, and illustrates the
    point by referencing cold cases that were solved after many years when DNA
    evidence was collected and linked to the unsolved matter. The government also
    argues that the “benefits” from the DNA Act include deterrence, insofar as a
    potential criminal is aware that the Act enhances law enforcement’s capacity to
    identify the perpetrators of crimes and prosecute them.
    Crime-solving through identification of such perpetrators can certainly
    constitute a legitimate government interest. (See 
    Robinson, supra
    , 47 Cal.4th at
    pp. 1121–1122.) At issue here is not whether the government can have a
    legitimate interest in solving crimes, but whether such a generalized interest ––
    without more –– is sufficient to overcome the privacy rights of individuals subject
    to arrest. We have made clear that where the primary purpose of a search or
    seizure is to detect crime or gather evidence of crime, the government must
    ordinarily have individualized suspicion that the person to be searched has
    committed a specific offense for the search or seizure to be valid. (See 
    Ingersoll, supra
    , 43 Cal.3d at pp. 1327–1328.) Such individualized suspicion is utterly
    16
    missing when the government searches all arrestees for evidence that, at some
    unknown time in some unknown place under unknown circumstances, they might
    have committed some other unidentified crime.
    The risk in simply embracing generalized crime-solving as sufficient
    justification for compelled collection of a DNA sample from someone who has
    merely been arrested is that such a move may be understood to justify searches
    and seizures of people and places without any particularized suspicion. The
    detection of legal wrongdoing is perhaps the preeminent justification for all
    policing activity, making such a generalized interest virtually always loom in the
    background when any law enforcement search is attempted. To allow such an
    interest to tip the balance and allow for, first, an intrusion into the body; second,
    analysis of the information seized therefrom; and, finally, potentially indefinite
    retention of the results (regardless of the outcome of the initial arrest that served as
    justification for the search), is to permit such an interest to become not only
    omnipresent but also omnipotent. Having trumped a person’s interest in what is
    often the most jealously guarded fount of information –– and having done so on
    the basis of nothing more than that the mere fact a person was subject to a felony
    arrest –– the diffuse governmental interest in generalized crime-solving will
    almost always overwhelm any offsetting consideration. Which is why we must be
    especially vigilant before embracing the government’s argument. (See 
    King, supra
    , 569 U.S. at p. 482 (dis. opn of Scalia, J.) [acknowledging that “the
    construction of [] a genetic panopticon,” culled from “the taking of DNA samples
    from anyone who flies on an airplane,” “applies for a driver’s license,” or “attends
    a public school” would have the “beneficial effect of solving more crimes” but
    denouncing the idea that this was enough to override “the charter of our
    liberties”].)
    17
    So it is beyond question that the government may deploy reasonable
    techniques to solve crime –– so long as those techniques do not effect a search or a
    seizure without individualized suspicion. Yet the fact that the class of persons
    subject to the DNA Act is limited to arrestees, rather than all citizens, does not
    give rise to the necessary threshold of suspicion to conduct a generalized search
    for incriminating information, nor does it change the usual presumption that
    searches are unlawful absent a warrant. Moreover, the warrant exception for a
    search incident to arrest is limited. It allows only for searches to uncover evidence
    of the crime that gave rise to the arrest itself or weapons that might be used to
    injure an arresting officer or accomplish an escape. 
    (Brisendine, supra
    , 13 Cal.3d
    at p. 539.) We made this rule clear in Brisendine, and have continued to adhere to
    it in subsequent cases, where we have refused to allow the fact of arrest to justify
    the warrantless search of arrestees, or their property, for items not related to one of
    these two governmental interests. (See 
    Ruggles, supra
    , 39 Cal.3d at pp. 11–12
    [finding search of containers in trunk of felony arrestee’s car unconstitutional];
    
    Laiwa, supra
    , 34 Cal.3d at pp. 727–728 [finding search of individual’s tote bag
    following arrest unconstitutional].)
    Under this authority, even full custodial arrest, booking, and incarceration
    will not authorize law enforcement to conduct an exploratory search of an arrestee
    in the hope of discovering evidence of another, possibly more serious crime. (See
    
    Laiwa, supra
    , 34 Cal.3d at pp. 727–728.) Rather, booking an arrestee into custody
    only permits a further search necessary to serve the government’s administrative
    needs. (Id. at p. 726; People v. Macabeo (2016) 1 Cal.5th 1206, 1214.) In
    contrast to such searches, the DNA collection at issue would effect a search and
    seizure to uncover evidence of any and all illicit activities — those committed in
    the past as well as those that might be committed in the future, none of which the
    State has justifiable reason to suspect that the arrestee has done. To allow such an
    18
    intrusion would contravene our precedent and dramatically expand the recognized
    exceptions to the warrant requirement.
    It is true that DNA sampling will “provide accurate and reliable
    identification of criminal offenders” and that “DNA samples, like fingerprints,
    may also be used to establish a suspect’s involvement in crimes.” (Maj. opn.,
    ante, at p. 35.) What does not follow from this observation is that the
    constitutionality of fingerprinting renders DNA sampling constitutional. To treat
    fingerprints and DNA samples as essentially similar is akin to comparing a single
    piece of fruit to a chain of supermarkets. Neither we, nor the high court, have ever
    held that the taking of fingerprints, photographs, or the like invades any
    expectation of privacy, or otherwise heightens the risks that bring article I, section
    13 or the Fourth Amendment into play.2 To the contrary, we have indicated that
    the taking of fingerprints is “standard police procedure,” rather than a search or
    seizure of an arrestee’s person. (People v. McInnis (1972) 
    6 Cal. 3d 821
    , 825–826;
    see also Loder v. Municipal Court (1976) 
    17 Cal. 3d 859
    , 865 (Loder).)3
    2       None of the cases the Attorney General cites is to the contrary. The
    Attorney General cites United States v. Mitchell (3d Cir. 2011) 
    652 F.3d 387
    , 411,
    for the proposition that the collecting of fingerprints has met with “universal
    approbation” from the courts. But in Mitchell, the court embraced the DNA-
    fingerprinting analogy in addressing a challenge to the federal DNA collection
    statute; the court did not consider a Fourth Amendment challenge to the practice
    of fingerprinting. The same is true of Doe v. Sheriff of DuPage County (7th Cir.
    1997) 
    128 F.3d 586
    , which did not consider a Fourth Amendment challenge to
    fingerprinting but instead addressed a defendant’s argument that the sheriff should
    have permitted persons surrendering on warrants to post bond without being taken
    into custody. (Id. at p. 588.)
    3       United States v. Kelly (2d Cir. 1932) 
    55 F.3d 67
    , 69, which the majority
    relies on here (maj. opn., ante, at pp. 36–37), likewise demonstrates only that
    fingerprinting is a commonplace means of identification — not that it is, like DNA
    collection, a search that implicates an individual’s constitutional rights.
    19
    Rather than finding these police processes to constitute reasonable
    invasions of an arrestee’s privacy, our precedent instead concludes that the taking
    of fingerprints or photographs does not implicate article I, section 13 at all. (See
    
    Loder, supra
    , at pp. 864–865 [arrestee’s right of privacy is not infringed by the
    taking of his fingerprints and photographs, or recording of his vital statistics].)
    The high court, likewise, has suggested that fingerprinting — and similar
    recordings of bodily characteristics that do not require an “intrusion into the body”
    — does not come within the Fourth Amendment’s scope. (See United States v.
    Dionisio (1973) 
    410 U.S. 1
    , 14–15; see also Davis v. Mississippi (1969) 
    394 U.S. 721
    , 727 [concluding that fingerprinting “involves none of the probing into an
    individual’s private life and thoughts that marks an interrogation or search”].) In
    contrast to the collection of DNA, fingerprinting does not intrude on a person’s
    bodily autonomy, or record information that is not otherwise available to public
    view (like the image of one’s face or markings on a person’s body). (Cf.
    
    Robinson, supra
    , 47 Cal.4th at pp. 1119–1120 [characterizing intrusions necessary
    for DNA profiling as “invasions of the body” constituting searches within the
    meaning of the Fourth Amendment].) All this makes it difficult to accept the
    majority’s argument that DNA collection is tantamount to fingerprinting and
    therefore necessarily constitutional. (See State v. Medina (2014) 
    102 A.3d 661
    ,
    682–683 [rejecting comparison of DNA collection to fingerprinting in holding
    Vermont’s DNA collection statute unlawful under Vermont Constitution’s
    prohibition against unreasonable searches and seizures].)
    A recent United States Supreme Court decision also cuts against treating
    fingerprinting and DNA collection as equivalent. In 
    Birchfield, supra
    , 136 S.Ct. at
    p. 2185, the high court held that the search incident to arrest doctrine does not
    justify the warrantless taking of a blood sample to measure blood alcohol content
    20
    (BAC). To reach this conclusion, the high court weighed the privacy interests
    affected by blood tests against the government’s need for such tests. It found that
    the tests implicated significant privacy concerns — not only because of the
    intrusive nature of the tests, which involve piercing the skin, but also because a
    blood sample contains sensitive information which may be susceptible to
    substantial further analysis. (Id. at p. 2178.) The court noted that a blood test
    “places in the hands of law enforcement authorities a sample that can be preserved
    and from which it is possible to extract information beyond a simple BAC
    reading.” (Ibid.) As such, “[e]ven if the law enforcement agency is precluded
    from testing the blood for any purpose other than to measure BAC, the potential
    remains and may result in anxiety for the person tested.” (Ibid.) In contrast,
    “breath tests are capable of revealing only one bit of information, the amount of
    alcohol in the subject’s breath.” (Id. at p. 2177.)
    Breath tests are like fingerprints, and DNA samples, like blood.
    Fingerprints reveal only limited bytes of information. Not so with DNA. DNA
    samples contain a wealth of genetic information, which would make an individual
    nervous about possible violations of his or her privacy as long as the information
    remains in the state’s possession. The Supreme Court had no trouble
    distinguishing between breath and blood tests, finding one constitutional and the
    other not. We likewise would do well not to ignore the distinction between DNA
    analysis and fingerprinting.
    Nor should we ignore that fingerprinting remains available to advance
    many of the very interests that allegedly support the DNA Act. The existence of
    fingerprints as a fast and accurate means to ascertain the identity of an arrestee
    21
    further diminishes the state’s interest in identifying individuals by their DNA.
    Undoubtedly there are some instances where a DNA sample may help to solve a
    cold case but a set of fingerprints would not. (See maj. opn., ante, at p. 37
    [identifying Robinson as one such case].) Nonetheless, just as the “reasonableness
    [of blood tests] must be judged in light of the availability of the less invasive
    alternative of a breath test” (
    Birchfield, supra
    , 136 S.Ct. at p. 2184), DNA tests
    must be judged in light of the availability of the less invasive alternative of
    fingerprints — even if the alternative is not a perfect substitute. The high court in
    Birchfield recognized various advantages that a blood test offers over a breath test
    (
    id. at pp.
    2184–2185), and yet did not find that enough for the former to pass
    constitutional muster. Instead, because “breath tests are significantly less intrusive
    than blood tests and in most cases amply serve law enforcement interests,” the
    court concluded that there was no sufficiently compelling justification for
    warrantless blood tests. (Id. at p. 2185, italics added.) The same conclusion
    follows with the DNA tests at issue here.
    III.
    Even as the DNA Act falls short of legitimately advancing the interests the
    government asserts, its requirements constitute a major intrusion into the privacy
    of all the people subject to its procedures. Focusing solely on the physical
    collection of DNA samples understates the invasion at issue in this case. The
    DNA Act is unusual in that it effects more than one intrusion into a person’s
    privacy and autonomy: the intrusion occurs not only when the arrestee is
    physically subjected to the DNA collection, but also when his biological sample is
    processed to create a DNA profile, stored indefinitely in federal and state
    databases, and potentially analyzed in the future when conducting comparisons
    22
    against newly obtained samples. This continuing intrusion makes the DNA Act’s
    search unlike other ordinary searches and seizures, as the potential infringement
    on an individual’s privacy is ongoing.
    The second intrusion — the processing, storage, and comparison of an
    individual’s DNA sample — is a far more significant invasion of an arrestee’s
    privacy. That one’s DNA reveals much of a person’s most private, closely
    guarded information is difficult to dispute. A DNA sample stored by the state
    contains an arrestee’s entire genetic code — information that has the capacity to
    reveal the individual’s race, biological sex, ethnic background, familial
    relationships, behavioral characteristics, health status, genetic diseases, pre-
    disposition to certain traits, and even the propensity to engage in violent or
    criminal behavior. (See United States v. Kriesel (9th Cir. 2013) 
    720 F.3d 1137
    ,
    1149, 1159–1160 [citing Krimsky & Simoncelli, Genetic Justice (2010) at pp.
    231–232]; see also Abrams & Garrett, DNA and Distrust (2016) 91 Notre Dame
    L.Rev. 757, 763.) The DNA profile maintained in state and federal databases thus
    has the potential to reveal vast amounts of personal information about those
    individuals, and to be used in ways starkly different relative to what justified the
    scheme. (Krent, Of Diaries and Data Banks: Use Restrictions Under the Fourth
    Amendment (1995) 74 Tex. L.Rev. 49, 95–96.) One can scarcely imagine personal
    information that falls more closely to the core of the “realm of guaranteed
    privacy” that constitutional protections against searches and seizures aim to
    protect. 
    (Kyllo, supra
    , 533 U.S. at p. 34; see also 
    Ruggles, supra
    , 39 Cal.3d at pp.
    9–10 [article I, section 13 considers whether a search interferes with a person’s
    reasonable expectations of privacy]; United States v. Amerson (2d Cir. 2007) 
    483 F.3d 73
    , 85 [describing the “vast amount of sensitive information that can be
    mined from a person’s DNA”].)
    23
    Given the extent of the interests involved, it should not be taken for granted
    that the State’s current practices or statutory provisions prohibiting misuse will
    mitigate the interference with an arrestee’s expectation of privacy. (Cf. maj. opn.,
    ante, at p. 38.) For one, it is not necessarily the actual use of an individual’s DNA
    that invades her reasonable expectations of privacy. (See 
    Birchfield, supra
    , 136
    S.Ct. at p. 2178 [“Even if the law enforcement agency is precluded from testing
    the blood for any purpose other than to measure BAC, the potential remains and
    may result in anxiety for the person tested.”].) Here, a privacy intrusion occurs
    from the mere fact of the government’s storage of an arrestee’s DNA, regardless
    of the way that the government uses it. That the government retains access to a
    person’s most private, sensitive genetic information — and the risks implicit in
    such access — constitutes a violation in itself, even if the government does not
    presently wring from the DNA all the flows of information to be found there.
    (Ibid.; see also United States v. Jones, 
    565 U.S. 400
    , 415–416 (conc. opn. of
    Sotomayor, J.) [finding continuous GPS monitoring to be an unconstitutional
    search in part because of the risk that the government “[could] store such records
    and efficiently mine them for information years into the future”].)
    Moreover, it is precisely this kind of intrusion that justifies California’s
    heightened privacy protections in the first place. As discussed above, the purpose
    of the constitutional grant of privacy is to protect citizens from governmental
    surveillance and other forms of information gathering. The DNA Act permits the
    government to store DNA with the potential to reveal information of an
    indisputably private nature. Article I, section 13 of our state Constitution — as
    informed by the privacy clause of article I, section 1 — protects against such an
    invasion of core privacy. (See 
    Ruggles, supra
    , 39 Cal.3d at pp. 9–10.)
    Furthermore, that the DNA Act invades the privacy of arrestees in
    particular does not mean we can ignore the resulting privacy invasion — or the
    24
    risks associated with it. We have rejected the premise that an individual placed
    under arrest — even custodial arrest — lacks a significant, constitutionally
    protected interest in the privacy of her person. We have done so for good reason:
    valid justification to arrest an individual for a specific offense does not
    consequently extinguish all of her privacy rights, nor does it imply –– without
    more –– that there is a basis to suspect her of involvement in any other kind of
    felony. 
    (Brisendine, supra
    , 13 Cal.3d at p. 556.) In contrast, convicted felons
    “ ‘retain no constitutional privacy interest against their correct identification.’ ”
    
    (Robinson, supra
    , 47 Cal.4th at p. 1121.) But we have never held, as the
    government argues, that individuals lawfully placed under custodial arrest lack a
    constitutionally protected interest in their genetic identity.
    Nor can we consider the privacy interests at stake in this case solely from
    the perspective of an individual who has been lawfully arrested and convicted. It
    is undisputed that Buza was arrested with probable cause and convicted of three
    felonies. But Buza declined to provide a sample of his DNA during his booking
    into jail — long before his felony convictions, and prior to a probable cause
    determination by a neutral magistrate. Whatever is the basis for a felony arrest,
    the arrestee may not be subjected to a presumption of guilt until proven innocent.
    At the time of refusal, Buza enjoyed the presumption of innocence, and the
    ultimate disposition of his felony charges was uncertain. At that moment, Buza
    had just as much a right to assert noncompliance in order to raise a challenge
    against the DNA Act as an arrestee who would eventually be acquitted of felony
    charges. Far from asserting the privacy interests of third parties, Buza challenges
    the DNA Act as it applies to himself under the circumstances of this case. (Cf.
    Sabri v. United States (2004) 
    541 U.S. 600
    , 609 [disapproving of a facial
    challenge to the constitutionality of a statute]; In re Cregler (1961) 
    56 Cal. 2d 308
    ,
    25
    313 [“one will not be heard to attack a statute on grounds that are not shown to be
    applicable to himself”].)
    Suppose we waited instead for another case brought by a plaintiff lawfully
    arrested for, and ultimately acquitted of, a felony charge. When this hypothetical
    plaintiff is told to submit to a DNA test upon arrest, she is presented with only two
    choices, both causing irreparable harm: (1) she could refuse the test and be
    lawfully prosecuted for (and found guilty of) a misdemeanor; or (2) she could
    submit to the test, and suffer the very harm to her privacy that she would later
    attempt to mitigate partially by seeking expungement. We may on occasion
    tolerate some degree of privacy harm and still uphold a search and seizure as
    reasonable. (See, e.g., People v. Medina (1972) 
    7 Cal. 3d 30
    , 40 [“Reasonableness
    of a search may depend on the degree of invasion of privacy which occurs.”
    (italics added)].) But this case raises more serious privacy concerns, because of
    the character of the information the government seeks to obtain. (See 
    Birchfield, supra
    , 136 S.Ct. at p. 2178; State v. 
    Medina, supra
    , 102 A.3d at p. 682 [stating
    that it is “important to note that the DNA samples being seized provide a massive
    amount of unique, private information about a person that goes beyond
    identification” in finding unconstitutional a state statutory amendment which had
    permitted DNA collection from all felony arraignees].) By declining to reach the
    issue here, we force a potential future plaintiff to suffer irreversible adverse
    consequences, either by penal sanction or harm to genetic informational privacy.
    This seems a substantial burden to impose upon an individual seeking to challenge
    the infirmities of the retention provisions, particularly where, based on the facts of
    this case, the majority already implicitly recognizes that there are likely
    constitutional defects in the statutory provisions regarding the government’s
    retention of genetic information. (Maj. opn., ante, at p. 25 [stating that “we must
    26
    leave for another day” the question of whether automatic expungement is
    constitutionally required for “the wrongly arrested or exonerated”].)
    That Buza was ultimately arraigned and convicted is therefore irrelevant to
    our analysis. (Cf. maj. opn., ante, at pp. 2, 41–44.) We must consider Buza’s
    claim in light of how he was situated when that claim accrued — when he was
    merely “[a]n arrestee whose arrest has not even been subjected to a judicial
    determination of probable cause,” and so held privacy interests “closest on the
    spectrum of privacy rights to an ordinary citizen.” (People v. Buza (2014) 
    231 Cal. App. 4th 1446
    , 1488; see People v. Triggs (1973) 
    8 Cal. 3d 884
    , 893 (Triggs)
    [“In seeking to honor reasonable expectations of privacy through our
    application of search and seizure law, we must consider the expectations of the
    innocent as well as the guilty.”].) The majority makes much of the fact that Buza
    made incriminating statements when he was arrested, which it takes to mean that
    he knew his arrest was supported by probable cause. (Maj. opn, ante, at pp. 20 &
    fn. 4, 42.) Why exactly an individual arrestee’s subjective belief about probable
    cause should factor into the analysis is far from clear, particularly since we
    consider probable cause objectively, from the point of view of a reasonable person
    in possession of all the facts known to the arresting officer. (E.g., Whren v. United
    States (1996) 
    517 U.S. 806
    , 812–813.) Moreover, simply because Buza knew the
    authorities were “going to regard [his setting fire to a police car] as an illegal act”
    does not mean that he forfeited all reasonable expectations of privacy.
    Irrespective of Buza’s state of mind when he was arrested, his refusal to allow
    collection of his DNA sample at booking spoke volumes in manifesting his
    subjective expectation of privacy. The question facing us here is whether that
    expectation is reasonable. Because of the veil of ignorance that prevents society
    from knowing for certain whether an arrested individual is in fact guilty of the
    offense that is the basis for the arrest, Buza was in every meaningful respect
    27
    indistinguishable from an arrestee who is later found to be innocent. So we
    explore the reasonableness of Buza’s privacy expectation from that perspective.
    Unlike the Maryland statute scrutinized in King, the DNA Act does not
    require that a lawful arrest have occurred before DNA collection, as it permits the
    retrieval and processing of a DNA sample before a magistrate or other judicial
    officer has determined that the arrest was supported by sufficient probable cause.
    This aspect of the DNA Act vastly expands the number of individuals subject to its
    dragnet. As Justice Liu points out, almost one in five felony arrestees are released
    prior to a judicial determination of probable cause. Yet all of these individuals
    must allow their DNA to be collected and retained by the state (for at least 180
    days) under threat of criminal sanction. (Pen. Code, § 299, subd. (c)(2)(D).) Even
    more invidiously, the fact that the state may compel a DNA sample from even
    those wrongfully arrested provides the perverse incentive for law enforcement to
    engage in pretextual arrests as a means to obtain a person’s DNA and wherefore
    uncover evidence of crimes.
    The DNA Act’s lack of an automatic expungement provision exacerbates
    such concerns. Again, unlike the Maryland statute, the Act does not require the
    destruction of the DNA sample and removal of any resulting profile from state and
    federal databases if the individual at issue is never convicted of a felony. Instead,
    the DNA Act requires a discharged arrestee to initiate expungement proceedings
    and navigate the resulting process himself. Although the Department of Justice
    assures us that the “vast majority of requests have resulted in expungement,” the
    Attorney General does not provide — and the record does not elsewhere contain
    — any information about how often eligible individuals initiate expungement
    proceedings in the first place. The absence of automatic expungement
    proceedings, and the employment of a process that requires the arrestee to initiate
    expungement and provide required documentation, heightens the possibility that
    28
    the State will retain possession of DNA profiles for individuals who were never
    convicted of qualifying felonies, who may never have been charged with a felony
    in the first place, or who may not have been lawfully arrested at all.
    Ironically, the interests advanced by the Attorney General on behalf of the
    state — i.e., generalized crime solving, proper housing of arrestees within the jails,
    and decision-making about pretrial release — are likely to be quite well-served
    even if the statutory scheme avoided its present constitutional defects. Indeed, the
    concerns about inadequate expungement measures and pretextual or abusive
    arrests could be alleviated by provisional amendments to the DNA Act already
    enacted by the Legislature. Under the version of the Act that will become
    operative if we affirm the appellate court, a jail official is not to transmit a DNA
    sample to the Department of Justice until there has been a felony arrest warrant
    signed by a magistrate, a grand jury indictment issued, or a judicial determination
    of probable cause for the arrest. (Pen. Code, § 298, subd. (a)(1)(A).) Waiting for
    a neutral determination of probable cause would add, at most, 48 hours to the 30
    days needed on average to process a DNA sample. (See County of Riverside v.
    McLaughlin (1991) 
    500 U.S. 44
    , 56.) In view of the delays already associated
    with DNA processing, postponing the process until a detached and neutral
    magistrate has found probable cause would diminish none of the state’s interests
    furthered by the DNA Act, since the state would be as able to “identify” arrestees
    after a 32-day waiting period as it would after a 30-day period. The amendment,
    however, would significantly cut down on the number of people whose privacy is
    invaded due to the analysis, storage, and comparison of their DNA samples.
    Nowhere does the majority seem to reject the merits of that approach. (See
    maj. opn., ante, at pp. 21–22.) Instead, it argues that since DNA processing is so
    slow, processing of the arrestees’ samples in practice — regardless of what the law
    permits — usually does not take place until judicial probable cause has been made
    29
    anyway. (Id. at p. 22.) The slow operation of existing technology and institutional
    practices thus become features supporting the constitutionality of the Act. As odd
    as this argument is, its force is sapped further still by the Act’s blanket permission
    for the processing of DNA samples even if a magistrate finds that the arrest was
    without probable cause. (See Pen. Code, § 298 [requiring jail officials to
    “promptly” forward biological samples to the Department of Justice without
    providing any exception for those wrongfully arrested].) The burden remains on
    the individual — even if wrongfully arrested or later exonerated — to seek
    expungement. But were we to strike down the Act, automatic expungement would
    become law. (See Pen. Code, § 299 [conditional provision to the Act requiring
    automatic expungement of DNA profiles from databank when the arrests do not
    lead to valid convictions].) In contrast, the existing statute creates a default
    regime that requires DNA samples from anyone subject to a felony arrest ––
    irrespective of whether they will eventually be judged guilty or whether a neutral
    magistrate finds probable cause — and leaves the state in a position to retain such
    information indefinitely unless expungement is pursued and achieved.
    None of these observations implies we should strike down the DNA Act
    because we prefer its replacement on policy or prudential grounds. (Cf. maj. opn.,
    ante, at p. 29, fn. 7.) Instead we emphasize what remains obvious even if
    downplayed by the majority: the Legislature has approved a law that
    accomplishes much of the Government’s interests while alleviating the
    constitutional problem.
    While the DNA Act is an initiative entitled to a presumption of validity, the
    searches it permits — and in fact, requires law enforcement to carry out — occur
    without a warrant or probable cause. If those searches are to be upheld, it is the
    State’s burden to persuade us that they fall within one of the recognized
    exceptions to the warrant requirement, or that they are otherwise reasonable.
    30
    While “mere doubt” about the DNA Act’s invalidity is not reason enough to strike
    it down (Calfarm Insurance Co. v. Deukmejian (1989) 
    48 Cal. 3d 805
    , 814
    (Calfarm)), we must nevertheless require the State to justify the searches the Act
    accomplishes. In this case, the State has not carried its burden to show the
    reasonableness of its searches when balanced against the interference with
    individual privacy. So provisions of the DNA Act authorizing such unreasonable
    searches must be struck down.
    Insofar as the majority would lean on majoritarian impulses to imply that
    something more is required because the Act is an initiative passed by voters (see
    maj. opn., ante, at pp. 22–23, 34, 44), we note that there is no formal distinction in
    our role in evaluating initiatives versus legislation enacted by representative
    political institutions. 
    (Calfarm, supra
    , 48 Cal.3d at pp. 814–815 [evaluating an
    initiative “ ‘in the light of established constitutional standards’ ” and finding it
    unconstitutional].) The Constitution applies both, and equally, to legislators and
    the general public. The majority cannot mean to suggest otherwise.
    In the final analysis, arrestees do not have such diminished expectation of
    privacy as to permit the State to retain their DNA profile and conduct repeated
    searches of it. As such, when weighed against the State’s generalized interest in
    identifying arrestees and solving crimes, an arrestee’s reasonable privacy interest
    in his or her genetic information — uniquely protected under the California
    Constitution — must win. 
    (Triggs, supra
    , 8 Cal.3d at p. 892 [“ ‘important as
    efficient law enforcement may be, it is more important that the right of privacy
    guaranteed by these constitutional provisions be respected’ ”].)
    31
    IV.
    The DNA Act unlawfully invades people’s reasonable expectation of
    privacy in their personal genetic information. Any diminished expectation of
    privacy arrestees may or may not have in their genetic code does not justify an
    intrusion of this magnitude. The government’s asserted interest in identifying
    individuals in its custody and solving crimes may prove important in justifying a
    variety of practices. But it does not countenance this intrusion, as the
    government’s rationale for the DNA Act is neither borne out by the Act’s
    implementation nor consistent with our precedent’s restrictions on suspicionless
    searches. This makes the DNA Act unconstitutional under our state charter as
    applied to felony arrestees — individuals, like Buza, who are not yet known to be
    lawfully arrested, much less found guilty. Far from invalidating the work of the
    California electorate, striking down the Act would vindicate our core
    constitutional values, which recognize that our citizens have the “inalienable
    rights” to be free of arbitrary governmental intrusion and to enjoy “safety,
    happiness, and privacy.” (Cal. Const., art. I, §§ 1, 13.)
    With respect, I dissent.
