  • Filed 12/3/14 Opinion on remand from Supreme Court
    CERTIFIED FOR PUBLICATION
    IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA
    FIRST APPELLATE DISTRICT
    DIVISION TWO
    THE PEOPLE,
    Plaintiff and Respondent,
    A125542
    v.
    MARK BUZA,                                               (San Francisco County
    Super. Ct. No. SCN 207818)
    Defendant and Appellant.
    The sole issue in this case is the constitutionality of a provision of the DNA and
    Forensic Identification Data Base and Data Bank Act of 1998, as amended (Pen. Code,
    § 295 et seq.) (the DNA Act),1 which requires that a DNA sample be taken from all
    adults arrested for or charged with any felony offense “immediately following arrest, or
    during the booking . . . process or as soon as administratively practicable after
    arrest . . . .” (§§ 296.1, subd. (a)(1)(A); 296, subd. (a)(2)(C).) In a prior opinion, we held
    that the seizure of appellant’s DNA shortly after his arrest, at a time when he was entitled
    to the presumption of innocence and there had been no judicial determination of probable
    cause to believe he committed the offense for which he was arrested, violated his right
    under the Fourth Amendment to the United States Constitution to be free from
    unreasonable searches and seizures. (People v. Buza, A125542, Aug. 4, 2011.) The case
    now returns to us with directions from the California Supreme Court to vacate our prior
    decision and reconsider the matter in light of Maryland v. King (2013) ___ U.S. ___ [
    133 S.Ct. 1958
    ] (King).
    1
    All statutory references are to the Penal Code unless otherwise indicated.
    1
    We have done so, and again reverse the judgment of conviction under the DNA
    Act. As we will explain, because of significant differences between the California DNA
    Act and the Maryland law considered in King, we question whether King establishes the
    validity of the California Act’s application to arrestees under the Fourth Amendment.
    We base our decision, however, solely upon article I, section 13, of the California
    Constitution, which in our view undoubtedly prohibits the search and seizure at issue.
    FACTS AND PROCEEDINGS BELOW
    Shortly after 3 o’clock on the morning of January 21, 2009, San Francisco Police
    Sergeant Jody Kato saw an orange glow emanating from a parked police car. When he
    realized the vehicle was on fire he saw a man, later identified as appellant, pop up from
    behind the vehicle and run into a nearby wooded area holding something in his hand.
    When another officer called out for him to surrender, appellant stepped out of the woods
    with his hands up. A search of the wooded area produced a road flare and a bottle
    containing a mixture of oil and gasoline. Matches were found in appellant’s pocket and a
    container of oil was found in his backpack. A fire department investigator concluded that
    all four tires of the patrol car had been damaged by fire, and traces of polystyrene,
    gasoline residue and/or medium weight oil were found on two of the tires.
    Several hours after his arrest, while he was confined in county jail and prior to any
    appearance before a magistrate or judge, appellant was asked to provide a DNA sample,
    as required by section 296, and refused, even after being informed that refusal to provide
    a sample would constitute a misdemeanor with which he would be charged.
    On February 17, 2009, appellant was charged by information with arson (§ 451,
    subd. (d)–count 1); possession of combustible material or incendiary device (§ 453,
    subd. (a)–count 2); vandalism (§ 594–count 3); and refusal or failure to provide a DNA
    specimen (§ 298.1, subd. (a)–count 4). Appellant pleaded not guilty to all four counts.
    With respect to the first three counts, appellant admitted at trial that he set fire to
    the patrol car’s tires using a mixture of oil, gasoline, and styrofoam as an accelerant. He
    did not commit his acts maliciously, he testified, but to protest what he considered a
    2
    corrupt government and system and to call attention to a political group he had formed,
    whose web sites had been “deleted from the Internet.”
    As to the fourth count, shortly after appellant’s arrest and while he was in county
    jail, San Francisco Sheriff’s Deputy Kenneth Washington advised appellant that state law
    required him to provide a DNA sample, which would be obtained by swabbing the inside
    of his cheek with a cotton-tipped swab. When appellant stated he did not wish to provide
    a sample, Deputy Washington showed appellant a Penal Code section 296 collection
    form which stated “the law about 296 PC requirements.” After appellant read the form,
    Deputy Washington again asked him to provide a sample, and appellant again refused.
    Appellant continued to refuse after being advised that his refusal was a misdemeanor
    offense with which he would be charged under section 298.1. Deputy Washington stated
    that provision of a DNA sample was required of all persons arrested for a felony offense,
    appellant had not been singled out, his DNA was not sought to connect him to evidence
    found at the scene, and it was not used for that purpose. Washington testified that at the
    time San Francisco deputy sheriffs seek a DNA sample from arrestees they also obtain
    two thumbprints and a signature, and he apparently had no difficulty obtaining these
    items from appellant.
    On April 22, 2009, appellant unsuccessfully moved for judgment of acquittal on
    count 4, contending that his arrest for a felony offense does not create a constitutionally
    adequate basis for requiring him to provide a biological sample.
    On April 30, 2009, the jury returned a verdict finding appellant guilty of all
    counts. That same day, the court ordered appellant to provide a DNA sample prior to
    sentencing. On May 28, 2009, after learning of appellant’s refusal to comply with this
    order, the court issued an order permitting the San Francisco Sheriff’s Department or the
    Department of Corrections to use “reasonable force, as outlined in P.C. 298.1, and in
    conjunction with guidelines of the Department of Corrections,” to “bring defendant Buza
    into compliance” with section 296. Prior to the July 6, 2009 sentencing hearing,
    appellant provided a DNA sample.
    3
    Appellant was sentenced to the low term of 16 months in state prison on count 1,
    with an additional concurrent 16-month sentence on count 2, and a concurrent six-month
    county jail term on count 4, refusal to provide a DNA sample. A 16-month sentence on
    count 3 was stayed pursuant to section 654. The court granted appellant appropriate
    custody and conduct credits, imposed appropriate restitution fines, and ordered him to
    register as an arson offender under section 457.1. The court also informed appellant that
    he would be included in the State’s DNA and forensic identification database and data
    bank program.
    After this court reversed the conviction on count 4, the California Supreme Court
    granted respondent’s petition for review (People v. Buza, S196200, Oct. 19, 2011), held
    the case pending the United States Supreme Court’s decision in King, 
    supra,
     
    133 S.Ct. 1958
    , then returned it to us for reconsideration. (People v. Buza, S196200, January 16,
    2013.)
    DISCUSSION
    I.
    The Statutory Scheme
    California law enforcement officials have been authorized to collect forensic
    identification blood, saliva or buccal (cheek) swab samples from persons convicted of
    certain serious crimes since 1984. (See former § 290.2, added by Stats. 1983, ch. 700,
    § 1.) In 1998, the Legislature enacted the DNA Act (§§ 295-300.3; Stats. 1998, ch. 696,
    § 2), which required “DNA and forensic identification data bank samples” from all
    persons convicted of specified offenses. (§ 295, subd. (b)(2).)2 The purpose of the DNA
    Act “is to assist federal, state, and local criminal justice and law enforcement agencies
    within and outside California in the expeditious and accurate detection and prosecution of
    individuals responsible for sex offenses and other crimes, the exclusion of suspects who
    “DNA database and data bank acts have been enacted in all 50 states as well as
    2
    by the federal government. (See 
    42 U.S.C. §§ 14131-14134
    ; and see Annot., Validity,
    Construction, and Operation of State DNA Database Statutes (2000) 
    76 A.L.R.5th 239
    ,
    252.)” (Alfaro v. Terhune (2002) 
    98 Cal.App.4th 492
    , 505.)
    4
    are being investigated for these crimes, and the identification of missing and unidentified
    persons, particularly abducted children.” (§ 295, subd. (c).)
    At the November 2004 General Election, California voters amended the DNA Act
    by enacting Proposition 69, the DNA Fingerprint, Unsolved Crime and Innocence
    Protection Act. That measure significantly enlarged the scope of persons subject to
    warrantless DNA searches by, among other things, providing that, beginning on
    January 1, 2009, warrantless seizure of DNA would be required of any adult arrested for
    or charged with any felony. (§ 296, subd. (a)(2)(C).)
    Pursuant to the DNA Act, collection of DNA must take place “immediately
    following arrest, or during the booking . . . process or as soon as administratively
    practicable after arrest, but, in any case, prior to release on bail or pending trial or any
    physical release from confinement or custody.” (§ 296.1, subd. (a)(1)(A).) DNA
    samples are ordinarily limited to collection of inner cheek cells of the mouth (buccal
    swab samples) with a small stick. (§ 295, subd. (e).) The taking of a DNA sample is
    mandatory; law enforcement officials lack discretion to suspend the requirement. (§ 296,
    subd. (d); People v. King (2000) 
    82 Cal.App.4th 1363
    , 1373.)
    After the sample is taken, it is sent to the DNA Laboratory of the California
    Department of Justice (DOJ), which is responsible for the management and
    administration of the state’s DNA and Forensic Identification Database and Data Bank
    Program and which stores, correlates and compares forensic identification samples for
    use in criminal investigations. (§§ 295, subds. (f), (g), (i)(1)(C); 295.1, subd. (c); People
    v. King, 
    supra,
     82 Cal.App.4th at p. 1370.) The Act directs the DOJ to analyze the DNA
    “only for identification purposes.” (§ 295.1, subd. (a).) A genetic profile is created from
    the sample based on 13 genetic loci known as “noncoding” or “junk” DNA, because they
    are not known to be associated with any particular genetic trait, disease or predisposition.
    (King, 
    supra,
     133 S.Ct. at pp. 1966-1967, 1968; Cal. Bureau of Forensic Services DNA
    FAQ (FAQ), Searching the CAL-DNA Data Bank and CODIS, Ques. 3
     [as of Dec. 1, 2014].) “[F]orensic analysis focuses
    on ‘repeated DNA sequences scattered throughout the human genome,’ known as ‘short
    5
    tandem repeats’ (STRs). [(J. Butler, Fundamentals of Forensic DNA Typing 5 (2009)
    (hereinafter Butler) at 147-148.)] The alternative possibilities for the size and frequency
    of these STRs at any given point along a strand of DNA are known as ‘alleles,’ [(id., at
    25)]; and multiple alleles are analyzed in order to ensure that a DNA profile matches only
    one individual. Future refinements may improve present technology, but even now STR
    analysis makes it ‘possible to determine whether a biological tissue matches a suspect
    with near certainty.’ ” (King, at p. 1967, quoting DA’s Office v. Osborne (2009) 
    557 U.S. 52
    , 62.)
    The profile derived from the DNA sample is uploaded into the state’s DNA data
    bank, which is part of the national Combined DNA Index System (CODIS),3 and can be
    3
    CODIS is a massive computer system which connects federal, state, and local
    DNA databanks. (CODIS Program and the National DNA Index System (Fact Sheet)
     [as
    of Dec. 1, 2014].) CODIS is also the name of the related computer software program.
    (Ibid.) CODIS’s national component is the National DNA Index System (NDIS), the
    receptacle for all DNA profiles submitted by federal, state, and local forensic
    laboratories. (Ibid.) DNA profiles typically originate at the Local DNA Index System
    (LDIS), then migrate to the State DNA Index System (SDIS), containing forensic profiles
    analyzed by local and state laboratories, and then to NDIS. (CODIS Brochure (Brochure)
     [as of Dec.
    1, 2014].) All three database levels work together to match DNA profiles.
    DNA databanks are growing rapidly. As of September 2014, NDIS contained
    over 11,164,117 offender profiles, 20,267,611 arrestee profiles and 583,444 forensic
    profiles. (CODIS-NDIS Statistics (Statistics) < http://www.fbi.gov/about-
    us/lab/biometric-analysis/codis/ndis-statistics>.) The FBI states that “[t]hrough the
    combination of increased Federal funding and expanded database laws, the number of
    profiles in NDIS continues to increase dramatically.” (Brochure, supra,
    ; Fact Sheet, supra, .) As of September 30, 2014,
    the California DNA Data Bank Program (CAL-DNA) contained 2,327,610 DNA samples
    received and logged, and 2,327,610 subject profiles uploaded pursuant to section 296.
    (California Department of Justice Proposition 69 DNA Data Bank Program Report for
    6
    accessed by local, state and federal law enforcement agencies and officials. (Brochure,
    supra, ;
    FAQ, supra, Searching the CAL-DNA Data Bank and CODIS .) When a DNA profile is uploaded, it is compared to profiles contained in
    the Convicted Offender and Arrestee Indices; if there is a “hit,” the laboratory conducts
    procedures to confirm the match and, if confirmed, obtains the identity of the suspect.
    (Fact Sheet, supra, .) The uploaded profile is also compared to crime scene profiles
    contained in the Forensic Index; again, if there is a hit, the match is confirmed by the
    laboratory. (Ibid.) CODIS also performs weekly searches of the entire system. (The FBI
    and DNA, Part 1 .) In
    CODIS, the profile does not include the name of the person from whom the DNA was
    collected or any case related information, but only a specimen identification number, an
    identifier for the agency that provided the sample, and the name of the personnel
    associated with the analysis. (Fact Sheet, supra, .)
    The DNA Act specifies that samples and profiles may be released only to law
    enforcement personnel and contains penalties for unauthorized use or disclosure of DNA
    information. (§ 299.5, subds. (f), (i).) A person whose DNA profile has been included in
    the state data bank may have his or her DNA specimen and sample destroyed, and
    database profile expunged from the data bank program, if he or she “has no past or
    present offense or pending charge which qualifies that person for inclusion within the . . .
    Data Bank Program and there otherwise is no legal basis for retaining the specimen or
    sample or searchable profile.” (§ 299, subd. (a).)
    The expungement process, however, is neither quick nor guaranteed. An arrestee
    may request expungement if the relevant charges are dropped before adjudication, after
    Third Quarter 2014 (DOJ Report) .) As of that date, the California DOJ reported 36,031 total
    hits, and 40,813 investigations aided. (Ibid.)
    7
    the statute of limitations for filing an accusatory pleading has run, or after being found
    factually innocent or not guilty of the offense. (§ 299, subds. (b)(1), (b)(3), (b)(4).) The
    arrestee must submit a request to the trial court and prosecutor of the county where the
    arrest occurred and to the DOJ’s DNA Laboratory; the court must then wait 180 days
    before it can grant the request; the court has discretion to grant or deny the request and its
    order is not reviewable by appeal or by writ. (§§ 299, subds. (c)(1), (c)(2)(D).)4 The
    4
    Section 299, subdivision (c)(2), provides: “Except as provided below, the
    Department of Justice shall destroy a specimen and sample and expunge the searchable
    DNA database profile pertaining to the person who has no present or past qualifying
    offense of record 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.”
    An individual may initiate expedited expungement proceedings by filing a request
    form and “sufficient supporting documentation of his/her identity, legal status, and
    criminal history” with the DOJ DNA Database Program. ( [as of Dec. 1, 2014].) Depending on the grounds for
    expungement, the required documentation may be a letter in support of expungement
    from a district attorney or prosecutor, or a certified or file-stamped copy of a court order,
    opinion, docket, or minute order. (Streamlined DNA Expungement Application Form
    244 ) If DOJ denies the request, the
    individual may initiate a court proceeding pursuant to the section 299 procedures.
    ()
    8
    DNA Act appears to allow the prosecutor to prevent expungement merely by objecting to
    the request. (§299, subd. (c)(2)(D).)
    II.
    The Fourth Amendment and Maryland v. King
    The Fourth Amendment protects “[t]he right of the people to be secure in their
    persons, houses, papers, and effects, against unreasonable searches and seizures . . . .”
    (U.S. Const., Amend. IV.) Subject only to a few specifically established and well-
    delineated exceptions not applicable here, warrantless searches are per se unreasonable
    under the Fourth Amendment (Missouri v. McNeely (2013) ___ U.S. ___, 
    133 S.Ct. 1552
    ,
    1558; City of Ontario v. Quon (2010) 
    560 U.S. 746
    , 760); the state thus bears the burden
    of showing that the search at issue is reasonable and therefore constitutional. (People v.
    Williams (1999) 
    20 Cal.4th 119
    ,127.) “ ‘As the text of the Fourth Amendment indicates,
    the ultimate measure of the constitutionality of a governmental search is
    “reasonableness.” ’ (Vernonia School Dist. 47J v. Acton (1995) 
    515 U.S. 646
    , 652.)
    [¶] ‘Reasonableness . . . is measured in objective terms by examining the totality of the
    circumstances’ (Ohio v. Robinette (1996) 
    519 U.S. 33
    , 39), and ‘whether a particular
    search meets the reasonableness standard “ ‘is judged by balancing its intrusion on the
    individual’s Fourth Amendment interests against its promotion of legitimate
    governmental interests.’ ” ’ (Vernonia School Dist. 47J . . . at pp. 652–653; see also
    Samson v. California (2006) 
    547 U.S. 843
    , 848 (Samson).)” (People v. Robinson (2010)
    
    47 Cal.4th 1104
    , 1120.)
    Nonconsensual extractions of substances that may be used for DNA profiling are
    “searches” entitled to the protection of the Fourth Amendment. (King, 
    supra,
     133 S.Ct.
    The DOJ posts monthly statistics for the DNA Laboratory which indicate the
    number of samples removed from the backlog. As the number of samples removed
    includes “any samples Expunged, Removed or Failed twice, as well as where a New
    Sample has been requested,” it does not reveal how many samples were expunged or how
    many profiles eligible for expungement exist in the databank. (Jan Bashinski DNA
    Laboratory Monthly Statistics .)

    sample]; Cupp v. Murphy (1973) 
    412 U.S. 291
    , 295 [finger nail scrapings].) The physical
    intrusion involved in the buccal swab procedure used in the present case has been viewed
    as minimal. (King, at p. 1969.) The collection of the DNA sample, however, is only the
    first part of the search authorized by the DNA Act; the second occurs when the DNA
    sample is analyzed and a profile created for use in state and federal DNA databases. The
    latter search is the true focus of our analysis.
    Federal and state statutes authorizing collection of DNA samples from persons
    convicted of qualifying offenses have been upheld universally by federal and state courts,
    albeit with significant debate and disagreement among the judges who decided these
    cases. (E.g., Banks v. United States (10th Cir. 2007)

    These cases emphasize, on the one hand, that convicted offenders are subject to “a
    ‘broad range of [restrictions] that might infringe constitutional rights in free society’ ”
    and have “severely constricted expectations of privacy relative to the general citizenry”
    10
    (Kincade, 
    supra,
     379 F.3d at pp. 833-834; see United States v. Kriesel (9th Cir. 2007)
    
    508 F.3d 941
    , 947 (Kriesel)), including no reasonable expectation of privacy in their
    identity. (Kincade, at p. 837; Kriesel, at p. 947; Hamilton v. Brown (9th Cir. 2010)
    
    630 F.3d 889

     59 F.3d at p. 1560; People v. Robinson, 
    supra,
     47 Cal.4th
    at p. 1121.) On the other hand, the government has a strong interest in identifying and
    prosecuting offenders and, in the case of those on supervised release, promoting
    rehabilitation and protecting the community. (Kincade, at pp. 833-835 [parolee]; Kriesel,
    at p. 947 [probationer]; Hamilton, at pp. 895-896 [inmate].) Accurate identification has
    been viewed as serving the governmental purposes of returning conditional releasees to
    prison if they reoffend, reducing recidivism through the deterrent effect of DNA
    profiling, and solving past crimes (Kincade, at pp. 838-839; Kriesel, at pp. 949-950), as
    well as avoiding erroneous convictions (People v. Robinson, at p. 1121).
    In King, the United States Supreme Court moved beyond the realm of convicted
    offenders, rejecting a Fourth Amendment challenge to a Maryland statute requiring
    collection of DNA from arrestees charged with “serious crimes.” (King, 
    supra,
     133 S.Ct.
    at p. 1970.) King described the “legitimate government interest” served by the Maryland
    DNA law as “the need for law enforcement officers in a safe and accurate way to process
    and identify the persons and possessions they must take into custody.” (Ibid.) The court
    viewed a suspect’s “identity” as including not only “his name or Social Security number”
    but also his or her criminal history, the latter being “critical” for the police to know when
    processing a suspect for detention because “[i]t is a common occurrence that ‘[p]eople
    detained for minor offenses can turn out to be the most devious and dangerous
    criminals.’ ” (Id. at p. 1971.) For this purpose, the court stated, “the only difference
    between DNA analysis and the accepted use of fingerprint databases is the unparalleled
    accuracy DNA provides.” (Id. at p. 1972.) “DNA is another metric of identification used
    to connect the arrested with his or her public persona, as reflected in records of his or her
    actions that are available to the police,” producing “a more comprehensive record of the
    suspect’s complete identity.” (Ibid.)
    11
    Employing this definition of “identity,” the court saw DNA identification of
    arrestees as helping ensure safety in a custodial setting by allowing law enforcement
    officers to “know the type of person whom they are detaining” and “make critical choices
    about how to proceed.” (King, supra, 133 S.Ct at p. 1972.) DNA information could help
    law enforcement assure an arrestee’s availability for trial by indicating arrestees who had
    committed more serious offenses in the past and might be more inclined to flee in order
    to avoid investigation that could expose the other offenses. (Id. at pp. 1972-1973.) The
    information could also inform bail decisions, because an arrestee’s “past conduct is
    essential to an assessment of the danger he poses to the public.” (Id. at p. 1973.)
    Acknowledging that it may take some time to obtain the results of DNA testing, the court
    observed that actual release often does not occur for a considerable time after the decision
    to release is made, information about the arrestee’s “identity and background” could be
    relevant to conditions of release or reconsideration of the decision to release, and DNA
    results obtained after release on bail could lead to revocation. (Id. at pp. 1973-1974.)
    Finally, the court noted that identification of an arrestee as the perpetrator of another
    crime could result in freeing a different person wrongfully imprisoned for that other
    offense. (Id. at p. 1974.)
    On the other side of the balance, the court held that the privacy expectations of a
    person taken into police custody “ ‘necessarily [are] of a diminished scope.’ ” (King,
    supra, 133 S.Ct. at p. 1978, quoting Bell v. Wolfish (1979) 
    441 U.S. 520
    , 557.) “Once an
    individual has been arrested on probable cause for a dangerous offense that may require
    detention before trial, . . . his or her expectations of privacy and freedom from police
    scrutiny are reduced.” (King, at p. 1978.) After finding the physical intrusion imposed
    by buccal swab minimal (id. at p. 1979), the court offered three reasons for concluding
    that the processing of the DNA sample did not intrude upon privacy rights in an
    unconstitutional manner: Only noncoding portions of the arrestee’s DNA, which would
    not reveal genetic traits, were analyzed; even if additional information could be gleaned
    from the DNA tested, the DNA was not in fact tested for such purposes; and testing for
    any purpose other than identification was prohibited. (Id. at pp. 1979-1980.)
    12
    In sum, the court held, “In light of the context of a valid arrest supported by
    probable cause respondent’s expectations of privacy were not offended by the minor
    intrusion of a brief swab of his cheeks. By contrast, that same context of arrest gives rise
    to significant state interests in identifying respondent not only so that the proper name
    can be attached to his charges but also so that the criminal justice system can make
    informed decisions concerning pretrial custody. Upon these considerations the Court
    concludes DNA identification of arrestees is a reasonable search that can be considered
    part of a routine booking procedure. When 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, 133 S.Ct. at p. 1980.)
    In a piercing dissent, Justice Scalia explained for himself and the three other
    dissenting Justices that the King majority’s interpretation of the Fourth Amendment
    departed markedly from prior Fourth Amendment jurisprudence by allowing the search
    of a person for evidence of a crime for which he or she has not been arrested, in the
    absence of any reason to think the person is guilty of any such other crime, possesses any
    incriminating evidence or presents any safety risk. The historical prohibition of such a
    search “is categorical and without exception; it lies at the very heart of the Fourth
    Amendment. Whenever this court has allowed a suspicionless search, it has insisted
    upon a justifying motive apart from the investigation.” (King, supra, 133 S.Ct. at p. 1980
    (dis. opn. of Scalia, J.).)
    Justice Scalia elaborated: “As ratified, the Fourth Amendment’s Warrant Clause
    forbids a warrant to ‘issue’ except ‘upon probable cause,’ and requires that it be
    ‘particula[r]’ (which is to say, individualized) to ‘the place to be searched, and the
    persons or things to be seized.’ And we have held that, even when a warrant is not
    constitutionally necessary, the Fourth Amendment’s general prohibition of
    “ ‘unreasonable’ searches imports the same requirement of individualized suspicion. See
    Chandler v. Miller [(1997)] 
    520 U.S. 305
    , 308.
    13
    “Although there is a ‘closely guarded category of constitutionally permissible
    suspicionless searches,’ 
    id., at 309
    , that has never included searches designed to serve
    ‘the normal need for law enforcement[.]’ Skinner v. Railway Labor Executives' Assn.[,
    supra,] 489 U.S. [at p.] 619 (internal quotation marks omitted) Even the common name
    for suspicionless searches—‘special needs’ searches—itself reflects that they must be
    justified, always, by concerns ‘other than crime detection.’ Chandler, 
    supra,
     at 313–314.
    We have approved random drug tests of railroad employees, yes—but only because the
    Government’s need to ‘regulat[e] the conduct of railroad employees to ensure safety’ is
    distinct from ‘normal law enforcement.’ Skinner, supra, at 620. So too we have
    approved suspicionless searches in public schools—but only because there the
    government acts in furtherance of its ‘responsibilities . . . as guardian and tutor of
    children entrusted to its care.’ Vernonia School Dist. 47J v. Acton[, supra,] 515 U.S. [at
    p.] 665.
    “So while the Court is correct to note (ante, at 1969 – 1970) that there are
    instances in which we have permitted searches without individualized suspicion, ‘[i]n
    none of these cases . . . did we indicate approval of a [search] whose primary purpose was
    to detect evidence of ordinary criminal wrongdoing.’ Indianapolis v. Edmond [(2000)]
    
    531 U.S. 32
    , 38. That limitation is crucial. It is only when a governmental purpose aside
    from crime-solving is at stake that we engage in the free-form ‘reasonableness’ inquiry
    that the Court indulges at length today. To put it another way, both the legitimacy of the
    Court’s method and the correctness of its outcome hinge entirely on the truth of a single
    proposition: that the primary purpose of these DNA searches is something other than
    simply discovering evidence of criminal wrongdoing. As I detail below, that proposition
    is wrong.
    “The Court alludes at several points (see ante, at 1970-1971, 1978-1979) to the
    fact that King was an arrestee, and arrestees may be validly searched incident to their
    arrest. But the Court does not really rest on this principle, and for good reason: The
    objects of a search incident to arrest must be either (1) weapons or evidence that might
    easily be destroyed, or (2) evidence relevant to the crime of arrest. See Arizona v. Gant
    14
    [(2009)] 
    556 U.S. 332
    , 343–344; Thornton v. United States [(2004)] 
    541 U.S. 615
    , 632
    (Scalia, J., concurring in judgment). Neither is the object of the search at issue here.
    [¶] . . . [¶]
    “At any rate, all this discussion is beside the point. No matter the degree of
    invasiveness, suspicionless searches are never allowed if their principal end is ordinary
    crime-solving. A search incident to arrest either serves other ends (such as officer safety,
    in a search for weapons) or is not suspicionless (as when there is reason to believe the
    arrestee possesses evidence relevant to the crime of arrest).” (King, supra, 133 S.Ct. at
    pp. 1981-1982 (dis. opn. of Scalia, J.).)
    The King dissenters highlighted critical issues we will return to later in this
    opinion, in particular the court’s novel view of identification and its acceptance of the
    analogy between DNA testing and fingerprinting. Even aside from criticism of the
    court’s underlying assumptions, however, we find it difficult to view King as controlling
    the outcome of the present case because of significant differences between the California
    DNA Act and the Maryland law. These include that the DNA Act applies to persons
    arrested for any felony, requires immediate collection and analysis of arrestees’ DNA
    even before a judicial determination of probable cause, and does not provide for
    automatic expungement of DNA data if an arrestee is not in fact convicted of a qualifying
    crime. While judicial opinions do not ordinarily indicate their applicability to disputes
    arising under different statutes or presenting different facts, the King majority stated its
    intention to create a rule of national application despite acknowledging differences in the
    “particulars” of various states’ DNA testing statutes. (King, 
    supra,
     133 S.Ct. at p. 1968.)5
    But it did so apparently without considering the ramifications of such differences, several
    5
    Noting that “[t]wenty-eight States and the Federal Government have adopted
    laws similar to the Maryland Act authorizing the collection of DNA from some or all
    arrestees,” the court stated that “[a]lthough those statutes vary in their particulars, such as
    what charges require a DNA sample, their similarity means that this case implicates more
    than the specific Maryland law. At issue is a standard, expanding technology already in
    widespread use throughout the Nation.” (King, supra, 133 S.Ct. at p. 1968.)
    15
    of which render its reasons for upholding the Maryland law completely inapplicable to
    California’s.
    The difference between the statutes in the timing of DNA analysis has several
    implications. While the Maryland law does not permit a DNA sample to be processed
    until after a judicial officer makes a probable cause determination and the arrestee is
    charged with a qualifying crime (King, supra, 133 S.Ct. at p. 1967), California’s DNA
    Act requires that DNA be collected “as soon as administratively practicable after arrest”
    (§ 296.1, subd. (a)(1)(A)) and permits processing of the sample to begin immediately.
    This means that the arrestee’s DNA may be processed on the basis of an arresting
    officer’s designation of the alleged crime, even if he or she is never charged with a
    qualifying—or indeed any—crime, and despite the fact that, because of the length of time
    necessary for processing a DNA sample, the DNA information will not be available for
    any of the purposes discussed in King before the arrestee is either released or arraigned.
    For individuals who are formally charged with a qualifying offense, the information will
    rarely be available materially sooner as a result of collection immediately upon arrest
    than it would be if collected upon arraignment. Yet the privacy expectations of a pre-
    arraignment arrestee are higher than those of an individual who has been subjected to a
    judicial determination of probable cause, and permitting DNA collection on the basis of
    an arresting officer’s determination of the crime increases the potential for abuse. King
    considered none of these issues.
    In addition, the difference in expungement provisions affects the weight of the
    arrestee’s privacy interests. Unlike the automatic expungement provisions of the
    Maryland law, California puts the burden on the arrestee to seek expungement, and
    outcome of the expungement process is not guaranteed. As the likelihood of
    expungement decreases, or the length of time necessary to obtain expungement increases,
    the privacy intrusion imposed by the government’s retention of the DNA profile and
    sample increases.
    Another difference between the statutes is that Maryland expressly prohibits
    familial DNA searches—searches in which a partial match between an individual’s DNA
    16
    profile and a profile in the DNA database is used to implicate a close biological relative
    of the DNA donor as a possible criminal suspect. (King, supra, 133 S.Ct. at p. 1967; Md.
    Pub. Saf. Code Ann. § 2-506(d).) California does not. As we later discuss, this
    difference is significant because familial DNA searching has nothing to do with
    “identifying” the DNA donor and has no use other than criminal investigation. At
    present, as a matter of policy, California limits familial DNA searches to DNA from
    convicted offenders. But this restriction is not imposed by the DNA Act.
    The DNA Act also differs from the Maryland law in that it applies to all felony
    arrestees rather than a subset limited by the serious nature of the crime of arrest. This
    difference further demonstrates that the purpose of the DNA Act is investigation of
    crime, not identification of arrestees. As Justice Scalia pointed out, the King majority
    describes its decision as applicable to persons arrested for serious offenses, but its logic
    would apply to any and every arrestee. “If one believes that DNA will ‘identify’
    someone arrested for assault, he must believe that it will ‘identify’ someone arrested for a
    traffic offense. . . . When there comes before us the taking of DNA from an arrestee for a
    traffic violation, the Court will predictably (and quite rightly) say, ‘We can find no
    significant difference between this case and King.’ Make no mistake about it: As an
    entirely predictable consequence of today’s decision, your DNA can be taken and entered
    into a national DNA database if you are ever arrested, rightly or wrongly, and for
    whatever reason.” (King, supra, 133 S.Ct. at p. 1989 (dis. opn. of Scalia, J.).) The more
    minor the crime of arrest, the more obvious it is that DNA is collected not to protect
    against some hidden risk to be discovered in “identifying” the arrestee, but to add to the
    database in furtherance of future crime-solving.
    In our view, the differences between the California and Maryland DNA laws
    significantly alter the weight of the governmental interests and privacy considerations to
    be balanced in determining constitutionality under the Fourth Amendment. We need not
    decide whether these differences require a different resolution of the issue from that of
    the King majority, however, as we focus our analysis instead upon the California
    17
    Constitution.6 Our conclusion that the DNA Act is invalid under article I, section 13, of
    the California Constitution renders it academic whether the Act is also invalid under the
    Fourth Amendment.
    III.
    The DNA Act’s Arrestee Provisions Violate the California Constitution
    Like the Fourth Amendment, article I, section 13, provides, “The right of the
    people to be secure in their persons, houses, papers, and effects against unreasonable
    seizures and searches may not be violated; and a warrant may not issue except on
    probable cause, supported by oath or affirmation, particularly describing the place to be
    searched and the persons and things to be seized.” Despite the all but identical language
    of the two constitutional provisions, the California Supreme Court has not always
    interpreted them as coextensive. Rather, the court has held that in this area, as in other
    6
    The California DNA Act was challenged in federal court, in a class action on
    behalf of persons who had been or would be compelled to submit to DNA searches solely
    because they have been arrested for or charged with a felony offense. (Haskell v. Harris
    (9th Cir. 2014) 
    745 F.3d 1269
    , 1270.) Prior to King, the district court denied a motion for
    a preliminary injunction. (Haskell v. Brown (N.D. Cal. 2009) 
    677 F.Supp.2d 1187
    , 1189-
    1190.) After King was decided, in a four-paragraph per curiam opinion, the Ninth Circuit
    affirmed the district court, finding the plaintiffs could not show they would likely succeed
    on the merits. (Haskell v. Harris, at p. 1271.) The full explanation of this conclusion is
    as follows: “Plaintiffs’ facial and as-applied challenges turn on essentially the same
    question: Is California’s DNA collection scheme constitutional as applied to anyone
    ‘arrested for, or charged with, a felony offense by California state or local officials?’
    After . . . King[, supra,] 
    133 S. Ct. 1958
    , the answer is clearly yes. Plaintiffs’ counsel
    conceded as much at oral argument. Given that concession, plaintiffs cannot show that
    the district court abused its discretion in denying a preliminary injunction that would
    apply to the entire class.” (Ibid.) The court declined the plaintiffs’ request for a
    preliminary injunction applying to a smaller class of individuals arrested for certain
    felonies that plaintiffs believed to be covered by King, directing that such a request would
    need to be made to the district court in the first instance. (Ibid.)
    Haskell v. Harris, supra, 
    745 F.3d 1269
     does not compel us to reach any particular
    resolution of the present case. First, Haskell did not adjudicate the constitutionality of the
    DNA Act; it only held that plaintiffs were not entitled to a preliminary injunction.
    Second, even with respect to a Fourth Amendment analysis, decisions of the Ninth
    Circuit are persuasive authority but not binding upon California state courts. (Raven v.
    Deukmejian (1990) 
    52 Cal.3d 336
    , 352 (Raven).)
    18
    constitutional analysis, the California Constitution is “a document of independent force.”
    (People v. Brisendine (1975) 
    13 Cal.3d 528
    , 549-550 (Brisendine); see, People v. Fields
    (1996) 
    13 Cal.4th 289
    , 298 [double jeopardy]; American Academy of Pediatrics v.
    Lungren (1997) 
    16 Cal.4th 307
    , 325-326 (American Academy) [privacy].) Further, the
    California Supreme Court has held that article I, section 13 imposes a “ ‘more exacting
    standard for cases arising within this state’ ” than does the Fourth Amendment. (People
    v. Ruggles (1985) 
    39 Cal.3d 1
    , 11-12 (Ruggles), quoting Brisendine, at p. 545.)
    While our Supreme Court has recognized a “general principle or policy of
    deference to United States Supreme Court decisions” in interpreting provisions of the
    California Constitution that are textually parallel to those of the federal Constitution
    (Raven, supra, 52 Cal.3d at p. 353), “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. (See,
    e.g., Raven[, at pp,], 352-354; Brisendine, supra, 13 Cal. 3d [at pp.] 548-551.)”
    (American Academy, 
    supra,
     16 Cal.4th at pp. 325-326.) Deference is not required when
    “ ‘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, at p. 353.) And where California authority
    establishes that the California Constitution provides greater protection, the United States
    Supreme Court’s interpretation of a textually parallel provision of the federal
    Constitution does not require our courts to weaken rights under the state Constitution.
    (American Academy, at p. 328.) The California Supreme Court “sits ‘as a court of last
    resort [in interpreting state constitutional guaranties], subject only to the qualification that
    our interpretations may not restrict the guarantees accorded the national citizenry under
    the federal charter.’ ” (Raven, at p. 354, quoting People v. Longwill (1975) 
    14 Cal.3d 943
    , 951, fn. 4.)
    This point is made explicit in our state Constitution: “Rights guaranteed by this
    Constitution are not dependent on those guaranteed by the United States Constitution.”
    19
    (Cal. Const., art. I, § 24.) Added to the Constitution by initiative in 1974, this provision
    did not create a new principle but, rather, “made explicit a preexisting fundamental
    principle of constitutional jurisprudence (see Ballot Pamp., Proposed Stats. and Amends.
    to Cal. Const. with arguments to voters, Gen. Elec. (Nov. 5, 1974), analysis by
    Legislative Analyst, p. 26)[.]” (Raven, supra, 52 Cal.3d at p. 354; Brisendine, supra, 13
    Cal.3d at p. 551 and fn. 19.)
    Indeed, as our Supreme Court has explained, the independence of state
    Constitutions is fundamental to principles of federalism and demonstrated by history.
    (Brisendine, supra, 13 Cal.3d at pp. 549-550.) “It is a fiction too long accepted that
    provisions in state Constitutions textually identical to the Bill of Rights were intended to
    mirror their federal counterpart. The lesson of history is otherwise: the Bill of Rights
    was based upon the corresponding provisions of the first state Constitutions, rather than
    the reverse.” (Id. at p. 550; see People v. Monge (1997) 
    16 Cal.4th 826
    , 872 (dis. opn. of
    Werdegar, J.).) “The federal Constitution was designed to guard the states as
    sovereignties against potential abuses of centralized government; state charters, however,
    were conceived as the first and at one time the only line of protection of the individual
    against the excesses of local officials.” (Brisendine, at p. 550.) Thus the Brisendine
    court stated that “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,” it was “simply reaffirming a basic principle
    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.” (Id., at pp. 550-
    551.)
    Our Supreme Court has enumerated several factors to consider in deciding
    whether a provision of the state Constitution should be construed differently from a
    parallel provision of the federal Constitution. In People v. Teresinski (1982) 
    30 Cal.3d 822
    , the court set out four reasons for deciding not to depart from the United States
    Supreme Court’s construction of the federal free speech clause: “First, ‘nothing in the
    20
    language or history of the California’ constitutional provision in question ‘suggest[ed]
    that the issue before us should be resolved differently than under’ the analogous federal
    constitutional ‘provision.’ ([Teresinski], at p. 836.) Second, the decision in question ‘did
    not overrule past precedent or limit previously established rights under’ the United States
    Constitution. ([Teresinski], at p. 836.) Third, the decision ‘was unanimous, and ha[d] not
    inspired extensive criticism.’ (Id. at pp. 836-837.) Fourth, the decision, ‘if followed by
    the courts of this state, would not overturn established California doctrine affording
    greater rights’ in the particular area. (Id. at p. 837.)” (Gerawan Farming, Inc. v. Lyons
    (2000) 
    24 Cal.4th 468
    , 510-511.)
    These factors all militate against applying King’s analysis in the present case.
    First, as we have said, the California Supreme Court has historically construed
    article I, section 13, of the California Constitution as imposing a “more exacting
    standard” than the Fourth Amendment in general, and specifically with respect to the
    scope of permissible searches of arrestees. (Brisendine, supra, 13 Cal.3d at p. 545;
    People v. Norman (1975) 
    14 Cal.3d 929
    , 938-939; Ruggles, supra, 39 Cal.3d at pp. 11-
    12.) Second, while King—being a case of first impression—did not overrule past
    precedent or limit previously established rights, as Justice Scalia forcefully described, the
    majority opinion deviated sharply from prior Fourth Amendment jurisprudence on
    suspicionless searches and searches incident to arrest. Third, far from being unanimous,
    King was decided by a narrow majority of five justices, with four in dissent. Finally,
    although following King would not overturn established California doctrine affording
    greater rights—again, King being a case of first impression—it would run counter to our
    Supreme Court’s prior application of a “higher standard of reasonableness under article I,
    section 13” (Brisendine, at p. 552), especially in the area of arrestee searches, and to
    California’s express constitutional protection of informational privacy. 7
    7
    Respondent argues that appellant cannot prevail on a facial challenge to the
    DNA Act because, since King upheld DNA collection from arrestees at booking,
    appellant cannot demonstrate that “no set of circumstances exists under which the Act
    would be valid.” (United States v. Salerno (1987) 
    481 U.S. 739
    , 745.) Appellant rejects
    21
    As we will explain, we find the King majority’s view of the purpose of DNA
    testing thoroughly inapplicable to the California DNA Act, and the court’s view of the
    information exposed through DNA testing too dismissive of scientific knowledge and
    practical considerations. For these reasons, we decline to adopt these views in analyzing
    the DNA Act under the California Constitution. Further, as we will also explain, the
    differences we have identified between the California and Maryland DNA laws decrease
    the weight attributable to the governmental interest in DNA testing at this early stage and,
    correspondingly, increase the weight of the privacy interests at stake. Accordingly, we
    find that the arrestee provisions of the California DNA Act do not pass muster under the
    California Constitution.
    the “facial challenge” characterization, noting that he does not challenge the DNA Act in
    all its applications—such as its requirement of postconviction DNA testing. Instead,
    appellant asserts, he is challenging only the specific search demanded of him, after his
    arrest and before he was formally charged, his refusal of which led to his criminal
    conviction under section 298.1. We need not resolve this point. Whatever the merits of a
    facial challenge to appellant’s Fourth Amendment claim, King would not foreclose
    appellant’s challenge under the California Constitution.
    Respondent contests appellant’s right to pursue a claim under the California
    Constitution because it was not “developed” at trial or by his appointed counsel on
    appeal. Respondent urges that appellant’s briefing initially “raised, but did not develop a
    state constitutional law claim,” that respondent pointed out this failure to develop a state
    law claim and argued such a claim would not be decided differently from a Fourth
    Amendment claim, that appellant’s appointed amicus then raised a state law claim, and
    that appellant’s “substantial” state law claim was made for the first time only after the
    case was remanded by the Supreme Court. This attempt to avoid the merits is surprising
    considering the procedural history of the appeal. This court, of its own initiative, invited
    the First District Appellate Project (FDAP) to file an amicus brief on the initial appeal in
    order to have the issues more fully developed. FDAP’S brief addressed the California
    Constitution, as well as the Fourth Amendment, albeit focusing on article I, section 1.
    After FDAP’s amicus brief was filed, FDAP was substituted as appellant’s counsel.
    Although we chose to resolve the case on federal constitutional grounds at that time,
    there is no basis for respondent’s attempt to prevent consideration of the issues under the
    California Constitution now. In any event, even if appellant had not earlier relied upon
    article I, section 13, we would not “ignore a constitutional provision directly applicable to
    an issue in a case before us simply because a party had neglected to cite it.” (People v.
    Runyan (2012) 
    54 Cal.4th 849
    , 859, fn. 3.)

    A.
    The DNA/Fingerprint Analogy
    The nature of the information at issue in DNA analysis is critical to assessment of
    the interests at stake in this case. Cases upholding DNA statutes invariably rely heavily
    on analogizing DNA testing to fingerprinting. (E.g., Rise, 
    supra,
     59 F.3d at p. 1559;
    United States v. Amerson, supra, 483 F.3d at p. 87.) King viewed DNA analysis simply
    as “an advanced technique superior to fingerprinting in many ways.” (King, 
    supra,
     133
    S.Ct. at p. 1976.) But “DNA contains an extensive amount of sensitive personal
    information beyond mere identifying information[.]” (County of San Diego v. Mason
    (2012) 
    209 Cal.App.4th 376
    , 381; see, Simoncelli, Dangerous Excursions: The Case
    Against Expanding Forensic DNA Databases to Innocent Persons (2006) 34 L.J. Med. &
    Ethics 390, 392 [“Unlike fingerprints—two-dimensional representations of the physical
    attributes of our fingertips that can only be used for identification—DNA samples can
    provide insights into personal family relationships, disease predisposition, physical
    attributes, and ancestry.”) A DNA sample contains the entire human genome, “the total
    of all that person’s genetic information.” (Greeley et al., Family Ties (2006) 
    34 J.L. Med. & Ethics 248
    , 249.)8
    8
    The King court’s minimizing of the nature and amount of information at issue in
    DNA analysis stands in stark contrast to its expansive view of the privacy interest
    involved in the recent case of Riley v. California (2014) ___ U.S. ___ [
    134 S.Ct. 2473
    ].
    There, in refusing to condone a warrantless search of data on an arrestee’s cell phone, the
    court recognized that “the possible intrusion on privacy” required consideration of the
    amount and nature of information stored on a cell phone, which can include
    “photographs, picture messages, text messages, Internet browsing history, a calendar, a
    thousand-entry phone book, and so on.” (Id. at p. 2489.) The court pointed out potential
    intrusions that could result from a data search with no indication they were involved in
    the particular case before the court: “An Internet search and browsing history, for
    example, can be found on an Internet-enabled phone and could reveal an individual’s
    private interests or concerns—perhaps a search for certain symptoms of disease, coupled
    with frequent visits to WebMD.” (Id. at p. 2490.) And the court pointed out that future
    technological developments would increase the problem: “We expect that the gulf
    between physical practicability and digital capacity will only continue to widen in the
    future.” (Id. at p. 2489.)
    23
    In general, like King, the cases upholding mandatory collection and processing of
    DNA have unjustifiably dismissed concerns about the extent of the personal information
    contained in DNA samples by limiting their attention to the profile used in DNA
    databanks, as currently restricted by statutes and scientific capability. (See, King, 
    supra,
    133 S.Ct. at pp. 1979-1980.) We have already mentioned that California currently uses
    the information contained in DNA profiles for purposes other than identification in
    familial searches based on convicted offenders’ DNA, a point we will discuss in detail
    later. The fact that investigators in California are able to conduct familial DNA
    searches—using the CODIS loci to discover a new suspect—disproves the King
    majority’s assumption that “the CODIS loci come from noncoding parts of the DNA that
    do not reveal the genetic traits of the arrestee” and “alleles at the CODIS loci ‘are not at
    present revealing information beyond identification.’ [Citation.]” (Id. at p. 1979.)
    Familial searches also disprove the King majority’s assumption that “even if non-coding
    alleles could provide some information,” they “ ‘are not at present revealing information
    beyond identification.’ [Citation.]” (Ibid.) While that may be true in Maryland, where
    familial searching is prohibited, it is demonstrably untrue in California. Notably, the
    King opinion added that if in the future police analyze samples to determine factors not
    relevant to identity, “that case would present additional privacy concerns not present
    here.” (Ibid.) Such is the case in California.
    But even accepting that the amount of personal information contained in the
    profile developed from noncoding portions of DNA is limited,9 the far greater danger to
    The court’s approach in King could not have been more different. The King court
    avoided any acknowledgement of the personal nature of DNA information, limited its
    consideration of privacy interests to the specific search involved, overlooked scientific
    developments in DNA analysis expanding its investigative use to persons who are neither
    offenders nor even arrestees, disregarded potential scientific developments increasing the
    information extracted from DNA, and then broadly extended its decision to DNA laws
    even more intrusive than the one before the court.
    9
    Questions about how much information may be derived from junk DNA now
    and in the future have been the subject of much debate in scientific and legal
    communities, and studies have begun to suggest links between the CODIS loci and
    24
    privacy lies in the DNA samples from which the CODIS profiles are developed, which,
    as we have said, contain the entire genome. DOJ’s laboratory is required to collect and
    store the blood specimens, buccal swab samples and other biological samples from which
    DNA profiles are derived. (§§ 295, subds. (h), (i)(1)(C), 295.1, subd. (c).) Like the DNA
    laws of almost every other state and federal law,10 the DNA Act is silent as to how long
    these specimens and samples may be kept, and it is reasonable to expect they will be
    preserved long into the future, when it may be possible to extract even more personal and
    private information than is now the case. “[T]he advance of science promises to make
    stored DNA only more revealing.” (Kincade, supra, 379 F.3d at p. 842, fn. 3 (conc. opn.
    of Gould, J.).)
    Moreover, as we will explain, the Act places few restrictions on the law
    enforcement uses to which such information may be put. (See discussion, post, at pp. 33-
    34.) This raises questions both about the kind of personal and private information that
    may be derived from the DNA samples in the DOJ’s possession, and the uses of that
    biometric data as scientific developments increase the type and amount of information
    that can be extracted from it. For example, commentators have discussed the potential
    for research to identify genetic causes of antisocial behavior that might be used to justify
    various crime control measures. (See Reclaiming “Abandoned” DNA, supra,100 Nw. U.
    susceptibility to certain diseases, as well as family relationships and ancestry. (Cole, Is
    The “Junk” DNA Designation Bunk? (2007) 102 Nw. U. L.Rev. Colloquy 54; Rosen,

    DNA Databases (2013) p. 5 .)

    Wisconsin apparently has been the only state whose DNA law requires the
    destruction of all specimens and samples after analysis has been performed and the
    applicable court proceedings have concluded. (Joh, Reclaiming “Abandoned” DNA:
    The Fourth Amendment and Genetic Privacy (2006) 100 Nw.U. L.Rev. 857, 871, fn. 77,
    citing 
    Wis. Stat. Ann. § 165.77
    (3) (West 2004).) The Wisconsin statute was amended in
    2013, however, to remove this requirement effective April 1, 2015. (
    Wis. Stat. Ann. § 165.77
    (3), Note (LEXIS 2014).)
    25
    L.Rev. at p. 878.) One post-King commentator has stated, “Genetics already has the
    power to expose familial ties. Research into still more sensitive information is ongoing,
    as briefs to the Court [in King] highlighted. [Citing Brief for Genetic Scientists Robert
    Nussbaum and Sara H. Katsanis as Amici Curiae in Support of Respondent at pp. 31-32
    and Brief of 14 Scholars of Forensic Evidence as Amici Curiae Supporting Respondent at
    pp. 38-39.] Government health and science institutes fund innumerable studies of this
    kind, and the research arm of the DOJ itself is sponsoring research into the intersection of
    genetics and delinquency. [Citing Kevin M. Beaver, Intersection of Genes, the
    Environment, and Crime and Delinquency: A Longitudinal Study of Offending (2010),
    available at 
    (studying five genes for interactions).] Academic and commercial sectors also actively
    pursue links between genetics and asocial behavior or addiction, and preliminary findings
    correlating one genetic variation with violence have recently been published. [Citing
    Widom & Brzustowicz, MAOA and the ‘Cycle of Violence,’ 60 Biological Psychiatry 684
    (2006) (citing studies of MAOA ‘violence’ gene) and Raine, The Anatomy of Violence:
    The Biological Roots of Crime (2013).] If the ‘pedophile gene’ were found, or the
    ‘violence gene’ established, then surely law enforcement will seek to mine genetic
    information for that ‘identification purpose.’ After all, law enforcement needs to know
    just whom it is dealing with.” (Murphy, License, Registration, Cheek Swab: DNA
    Testing and the Divided Court (2013) 127 Harv. L.Rev. 161, 180 (DNA Testing).)
    Further, as familial DNA searching demonstrates, DNA can be used to incriminate
    persons other than the suspect or offender from whom it is taken, while the information
    derived from fingerprints is limited to that one individual. In short, because the only
    information revealed by fingerprinting is a person’s identity, and DNA analysis has the
    potential to reveal every aspect of the person’s genetic make-up, fingerprinting presents
    no threat to privacy comparable to that posed by DNA analysis.11
    11
    Another distinction significant in considering the privacy interests at stake is
    that DNA testing is viewed by society as a process reserved exclusively for criminals.
    Because many professions and branches of civil service require fingerprinting, the

    B.
    Identification and Investigation
    Like the four dissenting Justices in King, we are unwilling to accept the premises
    that analysis of arrestees’ DNA is intended or in fact used for identification rather than
    investigation, or that “identification” encompasses investigating criminal history. The
    King majority’s construction of a new governmental interest in “identity” that includes
    not only verification of who an arrestee is but also what that person has done in the past
    allowed the court to elevate the “governmental interest” side of the balance in weighing
    the law’s promotion of “legitimate governmental interests” against its intrusion on
    arrestee’s reasonable expectation of privacy. Because this definition of “identity” folds
    investigation into identity verification, and because DNA testing at the time of arrest does
    not further actual identity verification, the court’s analysis distorted the “totality of the
    circumstances” required to be examined in measuring the reasonableness of the search at
    issue.
    The premises that arrestees’ DNA is used for identification and that identification
    includes criminal history permitted the King majority to view DNA testing of arrestees as
    falling within the established warrant exceptions for searches incident to arrest and
    booking. The result, as the dissenters explained, eviscerated protections against
    suspicionless searches long recognized under both the federal and state Constitutions.
    “The real expansion of warrantless search power in King is ‘its reimagination of the idea
    of “identity” to include criminal history and other information.’ ” (State v. Medina
    practice is “not in itself a badge of crime.” (United States v. Kelly (1932) 
    55 F.2d 67
    , 70;
    see also Thom v. New York Stock Exchange (S.D.N.Y. 1969) 
    306 F.Supp. 1002
    , 1007
    [“The day is long past when fingerprinting carried with it a stigma or any implication of
    criminality”].) In contrast, society views DNA sampling not just as a badge of crime, but
    as a badge of the most dangerous crimes: “DNA is used most commonly, both in the
    public perception and in reality, to detect more heinous crimes such as rape and murder.”
    (Note, Faulty Foundations: How the False Analogy to Routine Fingerprinting
    Undermines the Argument for Arrestee DNA Sampling (2010)

    (2014) ___A.3d___ Vt. 69 [
    2014 Vt. LEXIS 71
    , *42] (Medina) quoting DNA Testing[,
    supra,] 127 Harv. L.Rev. at p. 177.)
    The King court relied upon the principle that “ ‘[t]he constitutionality of a search
    incident to an arrest does not depend on whether there is any indication that the person
    arrested possesses weapons or evidence. The fact of a lawful arrest, standing alone,
    authorizes a search.’ ” (King, 
    supra,
     133 S.Ct. at p. 1971, quoting Michigan v.
    DeFillippo (1979) 
    443 U.S. 31
    , 35.) And “[b]ecause proper processing of arrestees is so
    important and has consequences for every stage of the criminal process, the Court has
    recognized that the ‘governmental interests underlying a station-house search of the
    arrestee’s person and possessions may in some circumstances be even greater than those
    supporting a search immediately following arrest.’ ” (King, at p. 1974, quoting Illinois v.
    Lafayette (1983) 
    462 U.S. 640
    , 645.)
    But, as Justice Scalia pointed out, the scope of a search incident to arrest is limited
    to weapons, easily destroyed evidence and evidence relevant to the crime of arrest.
    (King, 
    supra,
     133 S.Ct. at p. 1982 (dis. opn. of Scalia, J.), citing Arizona v. Gant, supra,
    556 U.S. at pp. 343-344 and Thornton v. United States, supra, 541 U.S. at p. 632 (conc.
    opn. of Scalia, J.).) A booking search may further extend to an inventory of the suspect’s
    personal effects. (Illinois v. Lafayette, 
    supra,
     462 U.S. at pp. 643-644.) An arrestee’s
    DNA falls in none of these categories.
    As Justice Scalia explained, it has been an established principle that warrantless
    searches without individualized suspicion may not be upheld where the “ ‘primary
    purpose’ ” of the search was “ ‘to detect evidence of ordinary criminal wrongdoing.’ ”
    (King, supra, 133 S.Ct. at pp. 1981-1982 (dis. opn. of Scalia, J.), quoting City of
    Indianapolis v. Edmond, 
    supra,
     531 U.S. at pp. 37-38, 44.) Justice Scalia noted that the
    DNA search in King served the purpose of “ ‘identifying’ King” only if “what one means
    by ‘identifying’ someone is ‘searching for evidence that he has committed crimes
    unrelated to the crime of arrest.’ . . . If identifying someone means finding out what
    unsolved crimes he has committed, then identification is indistinguishable from the
    28
    ordinary law-enforcement aims that have never been thought to justify a suspicionless
    search.” (King, at pp. 1982-1983 (dis. opn. of Scalia, J.).)
    By common understanding, “identification” means verifying who a person is. The
    Oxford English Dictionary defines the term as the “action or process of determining what
    a thing is or who a person is.” (5 Oxford English Dict. (2d ed. 1989) p. 619, col. 1.) In
    the context of fingerprinting, courts have drawn a distinction between identification—
    fingerprints taken “to verify that the person who is fingerprinted is really who he says he
    is,” and investigation—fingerprints taken “to connect [the person fingerprinted] to a
    crime with which he was not already connected.” (United States v. Garcia-Beltran (9th
    Cir. 2004) 
    389 F.3d 864
    , 867.) Fingerprints that are validly obtained for purposes of
    identification can later be used as evidence or in an investigation. (Loder v. Municipal
    Court (1976) 
    17 Cal.3d 859
    , 865.) Fingerprints obtained as a result of an illegal arrest are
    not subject to suppression if they were taken “solely to establish [the arrestee’s] true
    identity.” (Garcia-Beltran, at pp. 865-866.) But suppression is required if fingerprints
    were taken as a result of an illegal arrest for an “ ‘investigatory’ purpose, i.e., to connect
    [the arrestee] to alleged criminal activity . . . .” (Id. at p. 865; see Hayes v. Florida
    (1985) 
    470 U.S. 811
    ; Davis v. Mississippi (1969) 
    394 U.S. 721
    .)
    Identification in the sense of identity verification was from the outset the purpose
    of fingerprinting arrestees. The police began using fingerprinting as part of the booking
    process in the early 1900’s, as a reliable way to identify arrestees at a time when
    identifying documents were easily forged (Faulty Foundations, supra,19 Wm. & Mary
    Bill Rts. J. at pp. 484-485) and “notoriety of the individual in the community [was] no
    longer a ready means of identification.” (United States v. Kelly, supra, 55 F.2d at p. 69.)
    The DNA collection and testing mandated by the DNA Act, however, does not
    serve this purpose, because DNA collected from an individual upon arrest cannot be used
    immediately to establish who that individual is. Before law enforcement can obtain
    information about an arrestee from DNA testing pursuant to the DNA Act, the DNA
    sample must be analyzed and a DNA profile created and run through a database. (CODIS
    Fact Sheet, supra, .) The majority opinion in King noted the assertion in the amicus brief of
    the State of California that “ ‘DNA identification database samples have been processed
    in as few as two days in California, although around 30 days has been average.’ ” (King,
    supra, 133 S.Ct. at p. 1973.)12 By contrast, fingerprints submitted electronically to the
    national fingerprint and criminal history system administered by the FBI yield a response
    in about 27 minutes. (Integrated Automated Fingerprint Identification System (IAFIS),
    Federal Bureau of Investigation  [as of Dec. 1, 2014].)13 Additionally, DNA profiles in
    the data bank are not identified by name or case information; after a hit is made, the law
    enforcement agency must contact the laboratory that submitted the DNA sample to obtain
    identifying information. (Fact Sheet, supra, .)
    12
    The Attorney General’s published monthly statistics for the state DNA
    laboratory suggest even longer processing times. In October 2014, the laboratory started
    with a backlog of 22,070 samples, added 12,204 samples and uploaded 9,815 profiles to
    CODIS. (Statistics, supra ) The numbers for prior months are similar. In September
    2014, the starting backlog was 24,591 samples, 14,619 new samples were added and
    16,987 profiles were uploaded. (Statistics, supra ) In June 2014, the starting backlog was 31,464
    samples, 13,730 new samples were added, and 14,332 profiles were uploaded. (Statistics,
    supra .)
    Based on these numbers, it would take the laboratory well over two months to work
    through the existing backlog and begin to analyze newly received samples.
    13
    Fingerprints and criminal history information from local, state and federal law
    enforcement agencies are compiled in the IAFIS, the “largest biometric database in the
    world,” administered by the FBI. IAFIS offers automatic fingerprint search capability,
    latent search capability, electronic image storage, and electronic exchange of fingerprints
    and responses.
    California uses the California Identification System (Cal-ID), the automated
    system maintained by the DOJ for retaining fingerprint files and identifying latent
    fingerprints. (Pen. Code, § 11112.1.) At the local level, live scan devices are used to
    capture fingerprints taken when an individual is booked and transmit them electronically
    to the DOJ, which then transmits them to the federal database. (See Orange County
    Crime Lab  [as of Dec. 1, 2014].)
    30
    California’s protocol for DNA collection and analysis confirms that DNA is not
    used to verify who a person is. Far from relieving law enforcement agencies of the need
    to take fingerprints, the Act requires collection of a right thumb print and a full palm print
    of each hand, as well as a DNA sample. (§ 296, subd. (a)(2)(C).) Before collecting a
    DNA sample by means of the standard collection kit provided by the DOJ to local and
    state law enforcement agencies, the agency is required to “identify the subject” (FAQ,
    supra, Collection Mechanics, Ques. 1.1 ),
    demonstrating that the immediate means of “identification” is not the subject’s DNA.
    Moreover, DNA samples are not taken from arrestees who have already had
    samples taken (FAQ, supra, Qualifying Offender Verification Criminal History
    Flags/Samples Taken, Rap Sheet “Flags” and Offender Verification
    ), which shows that an arrestee’s identity must be
    verified in some other fashion before a DNA sample can be collected. It also
    demonstrates that, as a practical matter, law enforcement agencies do not need or use the
    DNA taken at arrest for identification purposes.
    That DNA testing is not needed to verify an arrestee’s identity is unsurprising.
    Fingerprints can be and are used for this purpose; the only time DNA would be better
    suited or more accurate would be the very rare situation in which an arrestee has gone to
    the trouble of physically altering his or her fingerprints. In the words of the Vermont
    Supreme Court, “The current system of photographs and fingerprints fully responds to
    the need for identification of the defendant. In the many cases now consolidated in this
    appeal, the State has identified none in which there is a need for more accurate
    identification.” (Medina, supra, 
    2014 Vt. LEXIS 71
    , *32.)
    Not only are DNA profiles neither necessary nor helpful for verifying who a
    person is at the time of arrest, the fact that DNA testing cannot be used to immediately
    verify a person’s true identity confirms that collection of a DNA sample at arrest has
    31
    another purpose.14 Despite the language in the DNA Act limiting the use of DNA to
    “identification purposes” (§ 295.1, subd. (a)), it is apparent that Proposition 69—which
    was entitled the “DNA Fingerprint Unsolved Crime and Innocence Protection Act (italics
    added)—was designed to permit an arrestee’s DNA to be used for investigative purposes.
    The ballot arguments in favor of the measure relied heavily on crime-solving promises
    and concerns, emphasizing the utility of DNA in investigating and solving crime.15
    Proponents asserted that “ ‘[t]he chances of solving a rape or murder increase by 85%
    with an all-felon DNA database” and that taking a DNA sample at booking “is more
    efficient and helps police conduct accurate investigations. No wasting time chasing false
    14  Justice Scalia made this point: “To know [the actual workings of the DNA
    search at issue here] is to be instantly disabused of the notion that what happened had
    anything to do with identifying King.” (King, 
    supra,
     133 S.Ct. at p. 1983 (dis. opn. of
    Scalia, J.).) In addition to the lengthy period before the DNA sample is processed and the
    fact that no identifying information is stored in the DNA database, “the CODIS system
    works by checking to see whether any of the samples in the Unsolved Crimes Collection
    match any of the samples in the Convict and Arrestee Collection. [Citation.] That is
    sensible, if what one wants to do is solve those cold cases, but note what it requires: that
    the identity of the people whose DNA has been entered in the Convict and Arrestee
    Collection already be known. If one wanted to identify someone in custody using his
    DNA, the logical thing to do would be to compare that DNA against the Convict and
    Arrestee Collection: to search, in other words, the collection that could be used (by
    checking back with the submitting state agency) to identify people, rather than the
    collection of evidence from unsolved crimes, whose perpetrators are by definition
    unknown. But that is not what was done. And that is because this search had nothing to
    do with identification.” (Id. at pp. 1983-1985.) What the DNA search in King
    “identified” was the previously unidentified suspect in a prior unsolved crime, not the
    person from whom the sample was taken. (Id. at p. 1985.)
    15
    The ballot argument opened dramatically: “ ‘In California, the remains of a

    leads . . . .” (Id. at p. 62-63.) According to proponents, “[Proposition] 69 can prevent
    thousands of crimes by taking dangerous criminals off the streets,” and California’s
    existing DNA database was “too small, unable to deal with the thousands of unsolved
    rapes, murders, and child abductions.” (Ibid.)16
    Although Proposition 69 twice declared the state’s compelling interest in “accurate
    identification of criminal offenders,” the findings section of the proposed law makes clear
    that its critical purpose was crime-solving. (Ballot Pamp., Gen. Elec. (Nov. 2, 2004), text
    of Prop. 69, p. 135.) The findings identified a “critical and urgent need” to furnish law
    enforcement “with the latest scientific technology available for accurately and
    expeditiously identifying, apprehending, arresting, and convicting criminal offenders and
    exonerating persons wrongfully suspected or accused of crime.” (Ibid.) It was declared
    that law enforcement “should be able to use the DNA Database and Data Bank Program
    to substantially reduce the number of unsolved crimes; to help stop serial crime by
    quickly comparing DNA profiles of qualifying persons and evidence samples with as
    many investigations and cases as necessary to solve crime and apprehend perpetrators
    . . . .” (Ibid.) The findings stated that expansion of the DNA Database and Data Bank
    Program was “[t]he most reasonable and certain means” to solve crime effectively and to
    increase rapidly the number of “cold hits.” (Ibid.)
    Further, the text of the DNA Act does not restrict the investigatory uses to which
    DNA specimens, samples, and profiles may be put by law enforcement agencies. Despite
    the provision in the DNA Act that the DOJ “shall perform DNA analysis . . . only for
    identification purposes” (§ 295.1, subd. (a)), other provisions authorize release of DNA
    samples and profiles collected under the Act “to law enforcement agencies,” including
    “district attorneys’ offices and prosecuting city attorneys’ offices” (§ 299.5, subd. (f)),
    16
    To demonstrate the ineffectiveness of California’s then-existing DNA database,
    proponents compared California’s database to Virginia’s. “Virginia has a comprehensive
    DNA database including arrestees. Virginia’s population is less than Los Angeles
    County, but solves more crimes with DNA than California. In 2002, California solved
    148 cases; Virginia 445.” (Ballot Pamp., Gen. Elec. (Nov. 2, 2004), argument in favor of
    Prop. 69, p. 62.)
    33
    and, “when, in the discretion of law enforcement, disclosure is necessary because the
    DNA information pertains to the basis for law enforcement’s identification, arrest,
    investigation, prosecution, or exclusion of a particular person related to the case[,]”
    DNA information may be released “to a jury or grand jury, or in a document filed with a
    court or administrative agency, or as part of a judicial or administrative proceeding,” or
    may “become part of the public transcript or record of proceedings[.]” (§ 299.5, subd. (k),
    italics added.) The DNA Act thus expressly authorizes the use of government stored
    DNA, including samples containing the entire human genome, not just to “identify” a
    person in the sense of verifying who he or she is, or to ascertain an accused person’s
    innocence, but also to assist with the “arrest, investigation, prosecution, or exclusion” of
    a person. (§ 299.5, subd. (k).) And because the DNA Act authorizes retention of DNA
    samples as well as the profiles derived from them, those retained samples, can be used to
    criminally investigate persons whose DNA was obtained upon arrest many years earlier,
    even if they were never criminally charged or were acquitted.
    Apparently, the only limitation imposed by the Act’s references to “identification”
    is a prohibition against analysis and use of DNA for non-law enforcement purposes
    relating to matters such as an individual’s health, propensity for certain diseases or
    conduct, gender, or race. (See Kincade, 
    supra,
     379 F.3d at pp. 837-838; id. at p. 842,
    fn. 3 (dis. opn. of Gould, J.).) In other words, DNA is to be collected and analyzed for
    “identification” purposes in the sense that the only information that is supposed to be
    drawn from DNA samples is that which identifies the donor. But this identifying
    information is not used to “identify” the donor in relation to the arrest; it is used to
    investigate the donor’s connection to crime unrelated to the crime of arrest.
    Indeed, California is already using DNA information collected from convicted
    offenders for investigatory purposes completely unrelated to any definition of
    “identification” of the person from whom the DNA was taken. California was the first
    state to permit deliberate familial DNA searches, intentionally using DNA profiles to
    34
    investigate the donor’s close relatives as possible perpetrators.17 Law enforcement
    agencies are able to identify likely family relationships through “partial matches” of
    DNA profiles because of the distinctively high number of alleles shared by family
    members. Since every person inherits one allele at each of the 13 CODIS loci from each
    of his or her biological parents, everyone shares at least 13 alleles with each parent, and
    more if both parents happen to possess the same allele at one or more loci. (See Greeley
    et al., Family Ties (2006) 
    34 J.L. Med. & Ethics 248
    , 249-252.) It has been estimated
    that on average, a Caucasian parent and child (a population for which good published
    data exists) share 15.7 alleles of the 26 profiled in CODIS, and full siblings share an
    average of 16.7 alleles. (Id. at pp. 252-253.) In contrast, unrelated persons share an
    average of 8.7 alleles. (Id. at p. 252.)18 While a number of states and the federal
    government permit use of partial matches discovered fortuitously in the course of routine
    database searches, California is one of the few that allow deliberate searches for this
    purpose. (Fortuity, supra, 63 Stan. L.Rev. at pp. 753, 764, 767-769.)
    17
    The FBI’s website identifies four states as having “taken the lead” in familial
    searching: California, Colorado, New York, and Florida. (FBI, Laboratory Services,
    Familial Searching  [as
    of Dec. 1, 2014].)
    18
    Unlike an “exact match” which indicates that the owner of the profiled DNA
    was involved in the crime under investigation, a “partial match” “refers to two genetic
    profiles—one derived from a crime scene sample and the other from CODIS—that share
    some, but not all, of the thirteen core DNA loci that comprise a CODIS profile. This kind
    of match generally excludes the offender whose CODIS profile provides the match,
    because that individual’s DNA is demonstrably different from the crime scene sample. A
    partial match may instead inculpate the offender’s close genetic relatives as possible
    perpetrators of a crime because they, like the crime scene sample, share some but not all
    of the examined loci with the individual whose CODIS profile provided the partial match.
    The information derived from a partial match where two nonmatching profiles share rare
    genetic markers will be particularly suggestive of a relative’s involvement in a crime.”

    Mismatches for Close Relatives of an Excluded Suspect (1999) 112 Int’l J. Legal Med.
    176, 177.)
    35
    California law enforcement agencies have engaged in such deliberate familial
    searching for many years, though so far only with DNA profiles of convicted offenders
    (), and the California DOJ has made it clear that this
    use of non-coding or “junk” DNA relates solely to criminal investigations. In 2008, the
    DOJ sent all California law enforcement agencies and district attorneys’ offices an
    “Information Bulletin” stating that it had developed a “DNA Partial Match Reporting and
    Modified CODIS (Combined DNA Index System) Search Policy that may result in
    investigative information provided to law enforcement officials in unsolved cases where
    all other investigative leads have been exhausted.” (Cal. DOJ, Div. of Law Enforcement,
    Information Bulletin 2008-BFS-01, DNA Partial Match (Crime Scene DNA Profile to
    Offender) Policy (Bulletin), italics added  [as of Dec. 1, 2014.) The Bulletin states that “[t]he name of
    an offender who is not the source of the biological material from an unsolved case may
    be released in an investigation” when a partial match is discovered either fortuitously or
    as the result of a deliberate search, and sets forth a protocol to be followed and conditions
    which must be met in order to release the name “to the investigating agency” in either
    situation. (Id. at pp. 1-2, italics added.)19 The DOJ has also developed a software
    19
    With respect to a deliberate search, the Bulletin declares that “[w]hen a law
    enforcement agency is investigating an unsolved case that has critical public safety
    implications, the agency may request that DOJ conduct a modified CODIS search with
    the objective of identifying any offender(s) in the database who are likely to be related to
    the unknown perpetrator. In these situations, the name of an offender may be released to
    the investigating agency” provided that a specified protocol has been followed and its
    conditions all been met. (Bulletin, supra, at p. 2, italics added.)
    For a fortuitous partial discovery, the Bulletin states that “[w]hen a partial match
    occurs that has at least 15 shared STR alleles with an offender, DOJ will contact the local
    laboratory’s CODIS administrator to confirm that the case is not yet solved. If the case is
    still active, the case investigator should be notified of the partial match by the local
    CODIS laboratory and the process defined in the policy will be followed upon request.”
    (Bulletin, supra, at p. 2, italics added.)
    The Bulletin provides that “any costs associated with the special DNA testing of
    the crime scene evidence must be paid for by the investigative agency, unless the crime
    scene evidence testing was performed by DOJ.” (Bulletin, supra, at p. 3, italics added.)

    program to assist investigators in more effectively identifying familial relationships.
    (Fortuity, supra, 63 Stan. L.Rev. at pp. 753-754 [citing Spriggs, Familial Search
    Procedure, in CAL-DNA Data Bank Technical Procedures Manual, 27, 29, and
    Steinberger & Sims (2008) Finding Criminals Through the DNA of Their Relatives –
    Familial Searching of the California Offender DNA Database, 31 Prosecutor’s Brief
    38].)20
    In sum, the California DNA Act cannot reasonably be characterized as aimed at
    identification of the donor of a DNA sample. DNA taken at the time of arrest is not
    intended to be used, and cannot usefully be employed, to verify the arrestee’s identity; it
    is intended to be used and is in fact employed to investigate the arrestees’ possible
    20
    Further reflecting the importance of the investigative purpose of the DNA Act,
    respondent emphasizes that DNA testing of arrestees “is an important and effective law
    enforcement tool,” asserting that adult felony arrestees are “more likely than not become
    tomorrow’s convicted offenders.” The Attorney General’s website states that
    “[c]ollecting forensic identification DNA database samples from offenders at felony
    arrest, rather than after conviction has more than doubled the crime-solving efficacy of
    California’s database program.” (FAQ, supra, Effects of the All Adult Arrestee
    Provision, Ques. 2 .)
    This conclusion may be an overstatement. Analyses of DNA profiling and
    databases, including California’s, indicate that “ ‘hits’ and ‘investigations aided’ metrics
    are poor indicators of whether DNA databases aided in resolving criminal investigations”
    because this data does not reveal whether hits resulted in arrests or convictions. (James,
    Congressional Research Service, DNA Testing in Criminal Justice: Background, Current
    Law, Grants, and Issues (Feb. 25, 2014) at p. 6; RAND Corporation, Center on Quality
    Policing, Toward a Comparison of DNA Profiling and Databases in the United States and
    England (2010) (RAND study) at pp. 17, 20.) Further, “[d]atabase matches are more
    strongly related to the number of crime-scene samples than the number of offender
    profiles in the database” (RAND study at p. 20), and it has been suggested that, given the
    constraints of financial resources, the focus on increasing the database of offender
    profiles comes “at the cost of greater backlogs and fewer technicians for crime scene
    sample collection and analysis.” (DNA Testing, supra, 127 Harv. L.Rev. at pp. 182-183.)
    It has also been suggested that the impact of collecting DNA from arrestees may be small
    because many have previously been convicted, so already have profiles in the database,
    and many of the others will have profiles added upon conviction. (Kaye, The
    Constitutionality of DNA Sampling on Arrest (2001) 10 Cornell J. L. & Pub. Pol’y 455,
    502, fn. omitted.)
    37
    involvement in criminal conduct unrelated to the crime of arrest and to add to the DNA
    database for purposes of future crime-solving. Once again, Justice Scalia’s words are
    apt: “The Court’s assertion that DNA is being taken, not to solve crimes, but to identify
    those in the State’s custody, taxes the credulity of the credulous.” (King, supra, 133 S.Ct.
    at p. 1980 (dis. opn. of Scalia, J.).) Analysis of DNA collected from arrestees does not
    serve the asserted governmental purpose—identification—and the apparent actual
    purpose for taking DNA samples at this early stage—investigation—cannot be squared
    with established constitutional principles protecting against suspicionless searches.
    C.
    Arrestee Searches Under Article I, section 13, of the California Constitution
    As we have said, the scope of permissible searches of arrestees is one of the
    specific areas in which article I, section 13, has been held to provide greater protection
    than the Fourth Amendment. (Brisendine, supra, 
    13 Cal.3d 528
    ; Ruggles, supra, 
    39 Cal.3d 1
    .) In Brisendine, which was concerned with a search incident to an arrest for a
    minor offense that would not involve the defendant being taken into custody (Brisendine,
    at p. 533), the circumstances of the case justified a search of the defendant’s person and
    knapsack for weapons; at issue was a further search of closed containers within the
    knapsack (an opaque bottle and envelopes). (Id. at pp. 540-545.) Two then-recent
    United States Supreme Court cases, United States v. Robinson (1973) 
    414 U.S. 218
    (Robinson)—which was relied upon heavily in King, 
    supra,
     133 S.Ct. at pages 1971,
    1974, 1978—and Gustafson v. Florida (1973) 
    414 U.S. 260
    , had upheld such searches,
    holding that “ ‘in the case of a lawful custodial arrest a full search of the person is not
    only an exception to the warrant requirement of the Fourth Amendment, but is also a
    “reasonable” search under that Amendment.’ ” (Brisendine, at p. 547, quoting Robinson,
    at p. 235.) Prior California precedent was to the contrary, holding that where a defendant
    was arrested for an offense that did not have “ ‘instrumentalities’ ” or “ ‘fruits,’ ” and was
    to be released either upon citation or on bail rather than booked into jail, only a limited
    search for weapons was permissible. (Brisendine, at pp. 536-537; People v. Superior
    Court (Simon) 
    7 Cal.3d 186
    .)
    38
    Adhering to its own precedent, the Brisendine court explained, “In choosing
    between these irreconcilable rules we cannot accept the Robinson implication that ‘an
    individual lawfully subjected to a custodial arrest retains no significant Fourth
    Amendment interest in the privacy of his person.’ ([People v. Robinson, supra,] 414 U.S.
    at p. 237; Powell, J. concurring.) Whatever may be the merit of that view when an
    individual is ultimately to be booked and incarcerated—a question not presented here—
    we find it inappropriate in the context of an arrestee who will never be subjected to that
    process.” (Brisendine, supra, 13 Cal.3d at p. 547.) Accordingly, Brisendine reaffirmed
    and followed “the decisions, exemplified by Simon, which impose a higher standard of
    reasonableness under article I, section 13, of the California Constitution.” (Id. at p. 552.)
    This position was reiterated in People v. Norman, supra, 14 Cal.3d at pages 938-939, and
    People v. Longwill, supra, 14 Cal.3d at page 951. In People v. Laiwa (1983) 
    34 Cal.3d 711
    , 727 (Laiwa), the court reaffirmed that the scope of an arrestee search must be
    tailored to the particular justifications of the situation. Laiwa held that a search of the
    defendant’s tote bag could not be justified as an “accelerated booking search” (on the
    theory that the search would inevitably occur at booking) because the search at the time
    of arrest could involve a greater intrusion into the arrestee’s privacy than a jailhouse
    search (for example, a search in a public place), and the justifications for a booking
    search—inventory of the arrestee’s property and jail safety—were not served by a search
    at the time of arrest. (Id. at pp. 725-726.)
    These cases particularly emphasized the need to protect against warrantless
    exploratory searches for evidence unrelated to the crime of arrest. In Brisendine, the
    court observed that an ostensible search for weapons that was “merely a façade designed
    to provide justification for an exploratory search for narcotics . . . would have been
    illegal.” (Brisendine, supra, 13 Cal.3d at pp. 534-535.) Laiwa discussed the fact that if
    an “accelerated booking search” exception to the warrant requirement were recognized,
    “police officers would have a license to conduct an immediate ‘thorough search of the
    booking type’ of the person and effects of any individual they arrest without a warrant for
    a minor but bookable offense, in the hope of discovering evidence of a more serious
    39
    crime; if such evidence were found, the suspect would then be booked instead on the
    latter charge and the intrusion would be rationalized after the fact as an ‘accelerated
    booking search.’ ” (Laiwa, supra, 34 Cal.3d at p. 727-728.)21
    Respondent argues that Brisendine does not support any limitation on searches
    conducted when an arrestee is booked for a felony arrest, viewing the case as invoking
    the California Constitution only to enforce a statutory scheme that restricted the
    procedures police could employ after minor offenses for which an individual could avoid
    the booking process. It is true that Brisendine did not involve a felony arrest, but the
    point of the court’s discussion of these restrictions was that whether and to what extent a
    search is justified depends upon the circumstances of the encounter. Classification based
    on whether the individual would be cited, transported to a magistrate, or booked into jail
    was “essential to analysis, since both the justification and the scope of a weapons search
    incident to an arrest are dependent on the relative danger to the officer presented by each
    type.” (Brisendine, supra, 13 Cal.3d at p. 536.)
    Brisendine did not address the scope of booking searches—as the opinion
    expressly stated. (Brisendine, supra, 13 Cal.3d at p. 547.) The only point we draw from
    Brisendine is that the substantive scope of article I, section 13, is not limited by the
    United States Supreme Court’s interpretation of the Fourth Amendment, and may in
    compelling circumstances afford greater protection of an arrestee’s privacy interests.
    There is no reason to restrict this principle to cases involving minor offenses, as
    respondent does in arguing that the scope of a felony arrest and booking search in
    California is governed by Robinson. Indeed, the California Supreme Court has
    recognized the “more exacting standard” of article I, section 13, in a case involving a
    felony arrest. (Ruggles, supra, 39 Cal.3d at pp. 11-12.) In holding that probable cause to
    21
    In People v. Smith (1986) 
    103 Cal.App.3d 840
    , 845-846, cited with approval in
    Laiwa, supra, 34 Cal.3d at page 727, the court noted that “[t]o declare that arrestees have
    no further privacy interest in their personal property once it is subjected to a booking
    search would mean that all accused persons, whether subsequently found innocent or
    guilty, would be subject to having their effects rummaged through at will during the
    entire period of their incarceration. This is a result we cannot condone.”
    40
    search the defendant’s vehicle, including the trunk, did not justify the warrantless search
    of a briefcase and tote bags in the trunk, the Ruggles court relied in significant measure
    on the fact that “[e]ach day millions of Californians drive in automobiles, often taking
    with them, inside briefcases or other similar luggage, items of a highly personal or
    confidential nature. Permitting such containers to be searched on the basis of probable
    cause alone deprives the owner of the added protections of a warrant.” (Id. at pp. 12-13.)
    The human genome—an expansive (and expanding) trove of the most personal and
    confidential information a person can possess—is in need of at least as much protection
    against governmental intrusion as those containers.
    Respondent’s assertion that the scope of a booking search in California is
    governed by Robinson, supra, 
    414 U.S. 218
    , also appears to be based on the assumption
    that Proposition 8, which was adopted in 1982, requires us to follow federal precedent. It
    is critical, however, to distinguish the substantive scope of constitutional protection
    against warrantless searches and seizures from the remedy for violations of that
    protection. Since the adoption of Proposition 8, evidence cannot be excluded as violative
    of state protections against unreasonable search and seizure unless it would also be
    inadmissible under the Fourth Amendment. (In re Lance W. (1985) 
    37 Cal.3d 873
    , 888
    (Lance W.).)22 But Proposition 8 did not alter the “substantive scope” of California’s
    constitutional provision. (Lance W., at p. 886.) “What would have been an unlawful
    search or seizure in this state before the passage of [Proposition 8] would be unlawful
    today, and this is so even if it would pass muster under the federal Constitution.” (Lance
    W., at p. 886.)
    Respondent’s reliance upon People v. Diaz (2011) 
    51 Cal.4th 84
    , 90-95, is
    misplaced. Diaz, affirming the denial of a suppression motion, upheld a search of text
    22
    Proposition 8 added article I, section 28, subdivision (d), to the California
    Constitution, stating that “ ‘[e]xcept as provided by statute hereafter enacted by a two
    thirds vote of the membership in each house of the Legislature, relevant evidence shall
    not be excluded in any criminal proceeding . . . .’ ” (Lance W., supra, 37 Cal.3d at p.
    879.)
    41
    messages on a cell phone found on defendant’s person at time of arrest on the basis of
    Robinson and other United States Supreme Court precedent concerning the extent of a
    permissible search incident to arrest. (Diaz, at pp. 90-95.) Because it presented a
    question concerning suppression of evidence, the case was required to be decided solely
    under the Fourth Amendment, in accordance with “the United States Supreme Court’s
    binding precedent.” (Diaz, at pp. 88, 101.) The Diaz court, therefore, had no basis for
    inquiring whether the substantive scope of a permissible search should be viewed
    differently under the California Constitution—as the court did when it rejected Robinson
    in Brisendine. And even as to the suppression issue, Diaz has now been effectively
    overruled by the United States Supreme Court’s conclusion that the search incident to
    arrest exception to the warrant requirement does not apply to digital data on a cell phone
    in an arrestee’s possession. (Riley v. California, supra, ___ U.S. ___ [134 S.Ct. at pp.
    2493-2494].) The Riley court rested its decision on the absence of any connection
    between search of the digital data and officer safety or destruction of evidence, the
    concerns underlying the exception, and the far greater privacy interests implicated in this
    sort of search than in prior search incident to arrest cases. (Id. at pp. 2485-2491.)
    People v. Miranda (1987) 
    44 Cal.3d 57
    , the other case cited by respondent
    concerning booking searches, held that a letter in an envelope in the defendant’s pocket
    “during an inventory booking search” at the police station was admissible at trial. (Id. at
    pp. 81-82.) Citing Laiwa, supra, 34 Cal.3d at page 726, and Illinois v. Lafayette, 
    supra,
    462 U.S. at page 646, Miranda explained that “the purposes of and justifications for [a
    search of the personal effects of an arrested person at the time of booking] are essentially
    two—to safeguard and account for the arrestee’s belongings and to promote jail
    security.” (Miranda, at p. 81.) A search can be justified on this basis only if these
    purposes are met; neither a search before actual booking nor one conducted after the
    booking process has ended meet the test. (Laiwa, at p. 727; People v. Smith, supra, 103
    Cal.App.3d at p. 845.) Respondent does not explain how the taking of a DNA sample at
    booking, before a judicial determination of probable cause, would be justified as an
    inventory search or promote jail security.
    42
    Contrary to respondent’s assertion, the California Supreme Court has never held
    that in the area of search and seizure, the rights guaranteed by the state and federal
    Constitutions are necessarily “coextensive.” As respondent points out, the court has held
    that “the touchstone for all issues under the Fourth Amendment and article I, section 13
    of the California Constitution is reasonableness” (Ingersoll v. Palmer (1987) 
    43 Cal.3d 1321
    , 1329) and that the federal and state Constitutions “extend similar protection against
    ‘unreasonable searches and seizures.’ ” (Lance W., supra, 37 Cal.3d at p. 881.) But the
    fact that both provisions are analyzed through the prism of similar factors does not
    mandate the same outcome in all cases—as Brisendine and the other cases discussed
    above make clear. And, as we have said, Lance W. itself noted that the substantive scope
    of article I, section 13 was not affected by Proposition 8’s requirement that California
    courts admit evidence that would not be excluded under the Fourth Amendment. (Lance
    W., at p. 886.)
    People v. Crowson (1983) 
    33 Cal.3d 623
    , 629 (Crowson), overruled on other
    grounds in People v. Myers (1993) 
    5 Cal.4th 1193
    , 1195, is not to the contrary. In that
    case, the police had secretly recorded a conversation between the defendant and an
    accomplice while the two were alone in the back seat of a police car. The defendant
    challenged admission of the recording on the ground that the secret recording violated his
    right to privacy under article I, section 1, of the California Constitution. (Crowson, at pp.
    625, 628-629.) Rejecting this claim, Crowson stated, “In the search and seizure context,
    the article I, section 1 ‘privacy’ clause has never been held to establish a broader
    protection than that provided by the Fourth Amendment of the United States Constitution
    or article I, section 13 of the California Constitution. ‘[The] search and seizure and
    privacy protections [are] coextensive when applied to police surveillance in the criminal
    context.’ (People v. Owens (1980) 
    112 Cal.App.3d 441
    , 448-449.)” (Crowson, at p.
    629.) Under all three provisions, Crowson stated, the question was whether the defendant
    had a reasonable expectation of privacy in the conversation with his accomplice in the
    backseat of the police car. (Id. at p. 629.)
    43
    Crowson engaged in no analysis of the substance of the state and federal search
    and seizure provisions as compared to each other; it simply compared those two
    provisions, on the one hand, with the state privacy provision, on the other. Its
    observation that the privacy provision does not afford greater protection in the search and
    seizure context than would the search and seizure provisions themselves says nothing
    about the respective reach of either search and seizure provision in a given situation. The
    same is true of the two cases respondent offers as having cited Crowson with approval,
    Sheehan v San Francisco 49ers, Ltd. (2009) 
    45 Cal.4th 992
     and Hill v. National
    Collegiate Athletic Assn. (1994) 
    7 Cal.4th 1
    . Both Sheehan and Hill were civil cases in
    which the plaintiffs claimed violations of their constitutional right to privacy. Both noted
    the comparison of the two search and seizure provisions with the privacy provision;
    neither compared the federal and state search and seizure provisions with each other.
    Indeed, it would be surprising to find California cases decided after Proposition 8
    discussing differences in the substantive scope of the state and federal search and seizure
    provisions, as it is highly unusual for search and seizure issues to arise in any context
    other than a suppression motion, which Proposition 8 requires to be decided according to
    federal law. The unavailability of the exclusionary rule as a remedy for violations of the
    state Constitution that are not violations of the Fourth Amendment means that state courts
    considering suppression of evidence must engage in a Fourth Amendment analysis.
    (People v. Maikhio (2011) 
    51 Cal.4th 1074
    , 1089.) But the argument respondent draws
    from this fact—that although the substantive scope of article I, section 13, was unaffected
    by Proposition 8, arrestees’ rights are nevertheless “limited in a practical sense” by the
    absence of the exclusionary rule as a remedy—is too facile. The present case has nothing
    to do with the exclusionary rule: The question here is not whether an illegal search and
    seizure requires suppression of evidence at trial but whether the state can criminalize the
    refusal to comply with a search that would violate the state’s proscription against
    unreasonable searches. We are free to determine this issue on the basis of California
    precedent.
    44
    D.
    Intrusiveness of the California DNA Act
    The California DNA Act intrudes too quickly and too deeply into the privacy
    interests of arrestees.
    As we will explain, the fact that DNA is collected and analyzed immediately after
    arrest means that some of the arrestees subjected to collection will never be charged,
    much less convicted, of any crime—and, therefore, that the governmental interest in
    DNA collection is inapplicable while the privacy interest is effectively that of an ordinary
    citizen. The absence of automatic expungement procedures increases the privacy
    intrusion because DNA profiles and samples are likely to remain available to the
    government for some period of time after the justification for their collection has
    disappeared, potentially indefinitely. And the fact that familial DNA searches are not
    prohibited means that the Act would permit intrusion into the privacy interests of
    arrestees biological relatives if the DOJ were to alter its current policy of not using
    arrestees’ DNA for such searches.
    Because the constitutionality of collecting DNA from convicted offenders has
    been accepted, the governmental interest at stake in King was not in obtaining DNA at all
    but in obtaining DNA sooner than if it had to wait for conviction. The Vermont Supreme
    Court questioned the significance of this interest: As to the difference between obtaining
    DNA after arraignment and waiting for conviction, the court stated, “the State has not
    shown why quicker access to the DNA is a weighty interest, and we cannot find it to be
    so.” (Medina, supra, 
    2014 Vt. LEXIS 71
     at p. *49.)23
    23
    The Vermont court had previously established that the primary purpose of that
    state’s DNA law was to create a database to which DNA evidence from future crime
    scenes could be compared, not to investigate the donor for crimes already committed.
    (Medina, supra, 
    2014 Vt. LEXIS 71
    , at pp. *19-*20 ) Regarding the additional
    considerations of “accurate identification of persons who are subject to conditions of
    release, or those who are incarcerated pretrial”—the concerns at issue in King—the court
    said, “the need for more accurate identification [than that provided by photographs and
    fingerprints] is rare and apparently has not arisen among the large numbers of defendants
    joined in this case.” (Medina, at pp. *32, *48-49)
    45
    Justice Scalia pointed out in his King dissent that the majority’s decision had an
    “ironic result”: “The only arrestees to whom the outcome here will ever make a
    difference are those who have been acquitted of the crime of arrest (so that their DNA
    could not have been taken upon conviction). In other words, [the Maryland law]
    manages to burden uniquely the sole group for whom the Fourth Amendment’s
    protections ought to be most jealously guarded: people who are innocent of the State’s
    accusations.” (King, 
    supra,
     133 S.Ct. at p. 1989 (dis. opn. of Scalia, J.).)
    In California, the burdened group includes not only those ultimately acquitted of
    criminal conduct but also those never even charged. The percentage of arrestees
    potentially affected in the latter way is not small: Statistics published by the DOJ
    indicate that in 2012 (the most recent year for which these numbers are available), 62
    percent of felony arrestees who were not ultimately convicted—almost 20 percent of total
    felony arrestees—were never even charged with a crime.24 (Crime in California 2012,
    supra, at p. 50 .) The governmental interests found in King to justify DNA testing do
    not apply to this group of arrestees, who will neither be held for a prolonged period in
    pretrial custody nor released under court supervision. Absent exceptional circumstances,
    an arrestee who is in custody must be brought before a magistrate for a determination of
    probable cause to arrest within 48 hours. (County of Riverside v. McLaughlin (1991) 
    500 U.S. 44
    , 56-57; § 825, subd. (a)(1).)25 This defines the outer limit of the time an arrestee
    24
    For 2012, of the 93,052 arrestees who were not convicted, 57,601 were not
    charged. (California Department of Justice, Division of California Justice Information Services,
    Bureau of Criminal Information and Analysis, Criminal Justice Statistics Center, Crime in
    California 2012, at p. 50 (Crime in California 2012) ].)
    25
    Under County of Riverside v. McLaughlin, 
    supra,
     500 U.S. at page 57, where
    an arrestee does not receive a probable cause determination within 48 hours, the
    government must demonstrate “the existence of a bona fide emergency or other
    extraordinary circumstance.”
    46
    who is not ultimately charged may be held in custody. As we have seen, the processing
    of a DNA sample to develop a profile currently takes considerably longer than this.
    (King, 
    supra,
     133 S.Ct. at p. 1973; see pp 29-30 and fn. 8, ante [AG monthly statistics for
    DNA lab on processing time].) As a practical matter, DNA collected from individuals
    who are arrested but not charged cannot be used either to verify the identity of the
    arrestee or to serve the interests discussed in King. The only possible use law
    enforcement agencies can make of these arrestees’ DNA is in investigation of other
    crimes.
    In the present case, respondent’s only articulation of its interest in immediate DNA
    testing—as opposed to testing after a judicial determination of probable cause—is that
    the sooner the testing is accomplished, the lower the risk of a dangerous individual
    remaining unidentified. The weight of this time-limited interest is extremely low. At the
    same time, the privacy interest of the arrestee is considerably higher. Arrestees, while
    suspected of having committed a crime, still enjoy the presumption of innocence and
    therefore occupy a different place in constitutional analysis than convicted offenders,
    who by virtue of their convictions suffer a loss of certain constitutional rights. (See
    Friedman v. Boucher (9th 2009) 
    580 F.3d 847
    , 856-858; Medina, supra, 
    2014 Vt. LEXIS 71
     at p. *51.) An arrestee whose arrest has not even been subjected to a judicial
    determination of probable cause falls closest on the spectrum of privacy rights to an
    ordinary citizen.26
    Section 825, subdivision (a)(1), requires that an arrestee “be taken before the
    magistrate without unnecessary delay, and, in any event, within 48 hours after his or her
    arrest, excluding Sundays and holidays.”
    26
    Respondent has attempted to downplay the absence of a judicial determination
    of probable cause, arguing that “loss of freedom of choice and privacy are ‘inherent
    incidents’ of felony arrest,” and the “ ‘presumption of innocence’ does not entitle
    arrestees to claim the full protection of Fourth Amendment privacy guarantees available
    to ordinary citizens.” Appellant, however, has explicitly acknowledged that arrestees’
    privacy expectations are “less than members of the general public.” He argues only that
    his privacy rights are greater than those of prisoners, parolees and probationers.
    47
    Moreover, permitting DNA to be collected immediately after arrest effectively
    leaves the determination of who will be subjected to DNA testing entirely in the hands of
    arresting officers. In many situations, the conduct for which an individual is arrested
    might be viewed as fitting the definition of a number of different crimes; whether the
    offending behavior is charged as a misdemeanor or a felony is initially left to the
    judgment of the arresting officers, leaving room for variation between both jurisdictions
    and between individual officers. (See DNA Testing, supra, 127 Harv. L.Rev. at pp. 188-
    189.) As the Supreme Court has explained with respect to the federal Constitution,
    “ ‘The point of the Fourth Amendment, which often is not grasped by zealous officers, is
    not that it denies law enforcement the support of the usual inferences which reasonable
    men draw from evidence. Its protection consists in requiring that those inferences be
    drawn by a neutral and detached magistrate instead of being judged by the officer
    engaged in the often competitive enterprise of ferreting out crime.’ ” (Gerstein v. Pugh
    (1975) 
    420 U.S. 103
    , 112-113, quoting Johnson v. United States (1948) 
    333 U.S. 10
    , 13-
    14.) Under the DNA Act, however, processing can begin when the legal basis for arrest
    is only the arresting officer’s determination of probable cause, and the sample and
    resulting profile will be retained unless and until the arrestee succeeds in the onerous and
    perhaps quixotic process of having them expunged—even if the arrest is subsequently
    determined by a judicial officer to have been without sufficient cause. This means there
    is no check on the discretion of the officers who make the arrests that create the
    Respondent also relies upon the statement in In re York (1995) 
    9 Cal.4th 1133
    , that
    the “ ‘presumption of innocence is a doctrine that allocates the burden of proof in
    criminal trials; . . . it has no application to a determination of the rights of a pretrial
    detainee during confinement before his trial has even begun.’ ” (Id. at p. 1148, quoting
    Bell v. Wolfish, 
    supra,
     441 U.S. at p. 533.) The salient point in York was that a lawful
    arrest allows restrictions on the liberty to which a citizen is ordinarily entitled. But the
    mere fact of an arrest does not render it lawful, a judgment that can be made only after a
    judicial determination of probable cause. At the time appellant was asked for and refused
    to provide a DNA sample, no judicial officer had determined whether there was probable
    cause to believe he had committed a crime.
    48
    opportunity for DNA sampling until after the sample may have been used for
    investigative purposes.
    Further, aside from the undue discretion afforded to law enforcement officers to
    determine whether an arrestee will be subject to DNA testing, this aspect of the DNA Act
    opens an opportunity for actual abuse. Without questioning the integrity of most law
    enforcement officers, it is not difficult to think that the DNA Act might provide an
    incentive to pretextually arrest a person from whom the police desire a DNA sample, as
    the Act would permit officers to collect the DNA and then release the uncharged arrestee,
    thereby obviating the need for any judicial inquiry into probable cause. (See Laiwa,
    supra, 34 Cal.3d at pp. 727-729 [accelerated booking search would give police license to
    conduct booking search on arrest for minor offense in hope of discovering evidence of
    more serious crime]; Brisendine, supra, 13 Cal.3d at p. 534 [ostensible weapons search as
    façade to justify exploratory search for narcotics would be illegal].)27
    The fact that the DNA Act does not provide for automatic expungement increases
    the weight of the arrestee’s privacy interest. California places the burden on the arrestee
    to pursue an onerous judicial process which seemingly vests the prosecutor with power to
    prevent expungement merely by objecting to the request (§ 299, subd. (c)(2)(D)); gives
    the trial court discretion to deny expungement without specifying any parameters for the
    27
    The King majority indicated that one of the reasons no warrant was needed for
    an arrestee DNA search was that the Maryland law made collection of DNA from
    specified arrestees mandatory: “The DNA collection is not subject to the judgment of
    officers whose perspective might be ‘colored by their primary involvement in “the often
    competitive enterprise of ferreting out crime.” ’ Terry [v. Ohio (1968) 
    392 U.S. 1
    ,] 12,
    quoting Johnson v. United States[, supra,] 333 U.S. [at p.] 14. As noted by this Court in
    a different but still instructive context involving blood testing, ‘[b]oth the circumstances
    justifying toxicological testing and the permissible limits of such intrusions are defined
    narrowly and specifically in the regulations that authorize them. . . . Indeed, in light of
    the standardized nature of the tests and the minimal discretion vested in those charged
    with administering the program, there are virtually no facts for a neutral magistrate to
    evaluate.’ Skinner, supra, [489 U.S. at p. 622].” (King, 
    supra,
     133 S.Ct. at p. 1970.)
    Under the Maryland law, however, DNA is not analyzed until after a judicial
    determination of probable cause. The King majority’s point, that the absence of
    discretion protects against abuse, cannot be made about the DNA Act.
    49
    exercise of that discretion; and renders the trial order unreviewable by appeal or writ.
    The element of discretion—and, therefore, uncertainty—in these procedures raises a
    question whether they satisfy the requirement of federal law for states with access to
    CODIS to “promptly” expunge DNA information upon receipt of specified
    documentation that an arrestee’s charge did not result in conviction.28 In any event,
    according to a study funded by the National Institute of Justice (NIJ), in states where the
    responsibility for initiating the expungement process is placed upon the arrestee,
    “[i]nterviews with crime lab officials show that very few people initiate the process, so
    their profiles remain in the databases.” (DNA Sample Collection from Arrestees, NIJ
    (Dec. 12, 2012) .)29 Thus, in California, the government may retain indefinitely the
    28
    Under the federal DNA law, “the FBI expunges from the national DNA index
    the DNA information of a person included in the index on the basis of conviction for a
    qualifying federal offense if the FBI receives a certified copy of a final court order
    establishing that the conviction has been overturned” and “expunges the DNA
    information of a person included in the index on the basis of an arrest under federal
    authority if it receives a certified copy of a final court order establishing that the charge
    has been dismissed or has resulted in an acquittal or that no charge was filed within the
    applicable time period.” (
    73 Fed. Reg. 74932
    ; 
    42 U.S.C. § 14132
    , subd. (d)(1)(A).)
    Federal law requires each state, “[a]s a condition of access to the [DNA] index,” to
    “promptly expunge from that index the DNA analysis of a person included in the index
    by that State if [¶] . . . the responsible agency or official of that State receives” the above
    described documentation that the relevant conviction has been overturned, or charge has
    been dismissed, resulted in acquittal, or was not filed within the applicable time period.
    (
    42 U.S.C. § 14132
    , subd. (d)(2)(A).) While California is required to adhere to the
    federal standards in order to maintain access to CODIS (
    42 U.S.C. § 14132
    , subd.
    (d)(2)(A)), it is unclear whether and how this requirement is enforced.
    29
    As described on its website, the NIJ, “the research, development and evaluation
    agency of the United States Department of Justice,” “funded the Urban Institute to
    examine how key provisions in arrestee DNA legislation influence the logistical activities
    associated with DNA collection and analysis. The study involves a review of state and
    federal laws along with interviews of state crime laboratory representatives in 26 of the
    28 states that passed legislation authorizing collection of DNA from some subset of
    arrestees. Although the study is ongoing, the Urban Institute provided some preliminary
    50
    DNA of individuals who have not been convicted of or even charged with a qualifying
    offense.30
    In addition, due to California’s policy of familial searching, the California DNA
    Act intrudes upon the privacy of individuals who have not themselves come into any
    contact with law enforcement. This intrusion is worthy of discussion despite California’s
    present policy of using only convicted offenders’ DNA for familial searches (FAQ,
    supra, California’s Familial Search Policy ; Bulletin,
    supra, ) because the
    limitation to convicted offenders’ DNA is solely a matter of policy: Nothing in the DNA
    Act imposes this restriction. If collection of DNA from arrestees is upheld, it is difficult
    to imagine familial searches will continue to be limited to convicted offenders. The
    history of DNA testing in the criminal justice system has been one of steady expansion—
    from initial testing only of offenders convicted of specified serious crimes of violence, to
    testing of all felons, and now to testing of arrestees. In evaluating the degree to which the
    procedure intrudes upon Californians’ privacy rights, we cannot close our eyes to the
    obvious implications of upholding each further encroachment.
    Aside from their targeting of individuals who have done nothing to bring
    themselves into contact with the criminal justice system,31 familial DNA searches have a
    findings that are current as of June 2012.” ()
    30
    Under the Maryland law, by contrast, because DNA samples are not analyzed
    until after arraignment and are automatically expunged if the donor is not convicted, the
    DNA information of an arrestee who is not charged with a qualifying crime will never be
    at the government’s disposal; the DNA of an arrestee who is charged but not convicted
    will at most be in the government’s hands only during the period between arraignment
    and conclusion of the case. (See Medina, supra, 
    2014 Vt. LEXIS 71
    , at p. *49.)
    31
    As one commentator has noted, even if persons whose DNA profiles are in the
    California CODIS database have forfeited their privacy rights, “they surely cannot have
    relinquished the interests of their father, mother, brothers, sisters, and children. Familial
    searches exploit the government’s power to compel information from persons with
    diminished privacy (i.e., mandatory typing of the offender’s DNA profile) to then invade
    the privacy of their law-abiding relatives (by drawing inferences about the relatives’
    51
    discriminatory effect: These searches condition criminal suspicion on nothing more than
    the fact of being a close relative of a person whose profile is in the DNA database, and
    racial and ethnic minorities comprise a much greater portion of that database than their
    proportion in the population at large. (Kaye & Smith, DNA Databases: Legality,
    Legitimacy, and the Case for Population-Wide Coverage (2003) 2003 Wisc. L.Rev. 413,
    440-441 (DNA Databases); Relative Doubt, supra, 109 Mich. L.Rev. at p. 322; Duster,
    DNA Dragnets and Race: Larger Social Context, History, and Future (Nov.-Dec. 2008)
    21 GeneWatch 3, 3-4.)32
    The combined effect of the foregoing features of the DNA Act, with respect to
    arrestees, is certain to infringe the privacy of thousands of persons who were never
    convicted or even charged with the offense for which they were arrested. And the DNA
    Act would permit the infringement of arrestees’ relatives’ privacy as well, if the DOJ saw
    fit to alter its current policy on familial DNA searches. 33
    profile). Familial searching effectively amounts to a law that says, ‘The identity and
    probable genetic markers of the close relatives of any convicted offender [or arrestee]
    shall be entered in the national database.’ ” (Murphy, Relative Doubt: Familial Searches
    of DNA Databases (2010) 109 Mich. L.Rev. 291, 317 (Relative Doubt).)
    32
    A study of the impact of California familial search policy concluded that “the
    reliance on racially disproportionate databases will on average impact the targeting of
    suspicion, drawing disproportionate attention toward Hispanics and African-Americans
    and against Asian Americans, and weakly affecting Caucasians.” (Relative Doubt, supra,
    109 Mich. L.Rev. at p. 323.) Moreover, “even if searches never generated any actual
    discrimination, the mere reliance on offender databases raises an appearance of bias that
    the criminal justice system can little tolerate. Criticism of the system and its inequities
    has already deeply divided communities and undermined trust in and cooperation with
    law enforcement actors. Using offender databases to find relatives sends a message that
    in cases in which there is no evidence of the perpetrator’s identity or ethnicity, it is fair to
    focus suspicion on not just the usual suspects, but also the innocent relatives of the usual
    suspects.” (Ibid., see also, Duster, Selective Arrests, an Ever-Expanding DNA Forensic
    Database, and the Specter of an Early-Twenty-First-Century Equivalent of Phrenology,
    in Lazer (ed.) The Technology of Justice: DNA and the Criminal Justice System (2004).)
    33
    Such a change in policy would also exacerbate the discriminatory effect of
    familial searching since, in California, far more members of racial and ethnic minorities
    are arrested for felonies than are people who are not minorities. (Crime in California
    2012, supra, at p. 33 23 Cal.4th 225
    , 255, quoting Minnesota v. Carter (1998) 
    525 U.S. 83
    , 88.) For purposes of the privacy clause, “[a] ‘reasonable’ expectation of privacy
    is an objective entitlement founded on broadly based and widely accepted community
    norms. (See, e.g., Rest.2d Torts, supra, § 652D, com. c [‘The protection afforded to the
    candd/cd12/cd12.pdf?>.) In 2012, of the total 429,807 felony arrestees in California,
    149,044 were Caucasian, while 280,763 were Hispanic, African-American or “other.”
    (Ibid.)
    53
    plaintiff’s interest in his privacy must be relative to the customs of the time and place, to
    the occupation of the plaintiff and to the habits of his neighbors and fellow citizens.’]”
    (Hill, 
    supra,
     7 Cal.4th at p. 37.)
    It follows from these principles that the express protection for the right to privacy
    enshrined in the California Constitution cannot be ignored in considering what California
    society would consider a legitimate expectation of privacy. The values reflected in the
    state constitutional right to privacy necessarily inform and illuminate the scope of this
    aspect of a claim under article I, section 13—the reasonable expectation of privacy of a
    California arrestee.
    The Privacy Initiative protects both “interests in precluding the dissemination or
    misuse of sensitive and confidential information (‘informational privacy’)” and “interests
    in making intimate personal decisions or conducting personal activities without
    observation, intrusion, or interference (‘autonomy privacy’).” (Hill, supra, 7 Cal.4th at p.
    35.) But “[i]nformational privacy is the core value furthered by the Privacy Initiative.
    (White v. Davis [(1975)] 
    13 Cal.3d 757
    , 774.)” (Hill, at p. 35.) As the Hill court
    discussed, “[t]he principal focus of the Privacy Initiative is readily discernible. The
    Ballot Argument warns of unnecessary information gathering, use, and dissemination by
    public and private entities—images of ‘government snooping,’ computer stored and
    generated ‘dossiers’ and ‘ “cradle-to-grave” profiles on every American’ dominate the
    framers’ appeal to the voters. ([Ballot Pamp., Proposed Stats. and Amends. to Cal.
    Const. with arguments to voters, Gen. Elec. (Nov. 7, 1972) p. 26 (hereafter Ballot
    Argument)] at p. 26.) The evil addressed is government and business conduct in
    ‘collecting and stockpiling unnecessary information . . . and misusing information
    gathered for one purpose in order to serve other purposes or to embarrass . . . .’ (Id. at p.
    27.) ‘The [Privacy Initiative’s] primary purpose is to afford individuals some measure of
    protection against this most modern threat to personal privacy.’ (White[, at p.] 774.)”
    (Hill, 
    supra,
     7 Cal.4th at p. 21.)
    “A particular class of information is private when well-established social norms
    recognize the need to maximize individual control over its dissemination and use to
    54
    prevent unjustified embarrassment or indignity. Such norms create a threshold
    reasonable expectation of privacy in the data at issue. As the ballot argument observes,
    the California constitutional right of privacy ‘prevents government and business interests
    from [1] collecting and stockpiling unnecessary information about us and from [2]
    misusing information gathered for one purpose in order to serve other purposes or to
    embarrass us.’ (Ballot Argument, supra, at p. 27.)” (Hill, 
    supra,
     7 Cal.4th at pp. 35-36.)
    As we have seen, DNA samples contain an enormous amount of personal
    information—the entire human genome. DNA testing is neither necessary nor practical
    for the only non-investigative purpose advanced to justify it—verifying the identity of
    arrestees. Moreover, DNA ostensibly gathered for the purpose of identification is
    misused to serve another purpose, criminal investigation. Considering also that the DNA
    Act permits the indefinite retention of this material—even that of arrestees who are never
    charged or never convicted of any offense—the collection and indefinite storage of DNA
    samples is the epitome of the kind of stockpiling of personal and private information the
    Privacy Initiative meant to protect from unnecessary governmental intrusion. While King
    paid little if any attention to the length of time a DNA sample could be retained and the
    extent of the uses to which it could be put, including risks of unauthorized leaks or
    research, as well as human error in the processing and analyzing of DNA (DNA Testing,
    supra, 127 Harv. L.Rev. at pp. 192, 195), such concerns cannot be ignored under article I,
    section 13, as informed by the values reflected in article I, section 1, of our state
    Constitution—especially when informational privacy, the “core value” the Privacy
    Initiative was intended to protect, is at stake.
    The DNA Act attempts to address privacy concerns in two ways: First, by
    providing for expungement of DNA profiles from the database and destruction of DNA
    samples when the basis for including them has been proven unwarranted; and, second, by
    insisting upon confidentiality of “[a]ll DNA and forensic identification profiles and other
    identification information retained by the [DOJ] pursuant to this chapter” except as
    provided under the Act (§ 299.5, subd. (a)) and providing for criminal fines and terms of
    imprisonment for knowing use, or disclosure to an unauthorized individual or agency, of
    55
    a DNA sample or profile “for other than criminal identification or exclusion purposes” or
    “identification of missing persons” (§ 299.5, subd. (i)(1)(A)).
    These provisions, of course, do little to protect the privacy interests implicated by
    the investigatory use of DNA information, as described above. It is questionable how
    much protection they afford against other misuse of the information. As we have already
    described, the expungement procedures in the DNA Act put the burden of seeking
    expungement upon the arrestee, the process is onerous, and the DNA Act appears to
    allow the prosecutor—whose office has an obvious interest in as many DNA profiles and
    samples as possible for investigatory use—to block expungement simply by objecting;
    and the court has unreviewable and therefore unfettered discretion whether to order
    expungement. The DNA Act does not require the destruction of DNA samples after a
    specified period of time. To the contrary, section 299, subdivision (e), of the Act
    specifically declares that DOJ “is not required to expunge DNA profile or forensic
    identification information or destroy or return specimens, samples or print impressions
    taken pursuant to this section if the duty to register under Section 290 [the Sex Offender
    Rights Act] or 457.1 [requiring registration of persons convicted of arson] is terminated.”
    The DOJ is simply “authorized” to dispose of unused specimens and samples or unused
    portions thereof, “in the normal course of business and in a reasonable manner as long as
    the disposal method is designed to protect the identity and origin of specimens and
    samples from disclosure to third persons who are not a part of law enforcement.”
    (§ 299.7.)
    As for the enforcement provisions, although the DNA Act criminalizes misuse of
    DNA information, it is difficult to imagine these provisions being enforced in any but the
    most exceptional cases. There is no civil remedy for misuse of DNA information
    (§ 299.5, subd. (i)(2)(B)); the DNA Act requires the government, whose interest is in
    collecting, analyzing, retaining and using DNA samples, to police itself. Most arrestees
    will never know if their DNA information has been misused, and even if they do, few are
    likely to be aware of the existence of criminal penalties and in a position to pursue them.
    And if an arrestee were able to get this far, the likelihood of a prosecutor pursuing
    56
    criminal charges in the average case is not great, given the governmental interest in
    crime-solving.
    In light of the concerns underlying the Privacy Initiative, the nature and extent of
    personal information contained in DNA samples, and the likely indefinite retention of
    such samples for many individuals who are never found to have committed a crime, the
    privacy interest at stake in this case is extremely weighty.
    IV.
    Conclusion
    The question this case presents, which is increasingly presented to the courts of
    this state and nation, is the extent to which technology can be permitted to “shrink the
    realm of guaranteed privacy.” (Kyllo v. United States (2001) 
    533 U.S. 27
    , 34.) The
    information contained in a DNA profile—and even more so that in a DNA sample—is
    deeply personal; “[o]ne can think of few subject areas more personal and more likely to
    implicate privacy interests than that of one’s health or genetic make-up.” (Norman-
    Bloodsaw v. Lawrence Berkeley Lab. (9th Cir. 1998) 
    135 F.3d 1260
    , 1269.) The DNA
    Act permits the specimens seized by the police without a warrant to be retained by the
    DOJ indefinitely. The profiles derived from these DNA samples are passed on to the FBI
    for placement in CODIS and, like the samples themselves, may be disclosed to and used
    by criminal law enforcement officers and agencies to solve crimes other than those for
    which a person was arrested and to implicate biological relatives of the person from
    whom a sample is taken as criminal suspects.
    On the continuum of privacy rights ranging from ordinary citizens, with full
    expectation of privacy, to incarcerated prisoners, with a very limited expectation of
    privacy (see Samson, 
    supra,
     547 U.S. at p. 850), the privacy rights of arrestees are greater
    than those of probationers, parolees or convicted prisoners. Within the category of
    arrestees, an individual such as appellant, who has not yet been the subject of a judicial
    determination of probable cause, falls closer to the ordinary citizen end of the continuum
    than one as to whom probable cause has been found by a judicial officer or grand jury.
    And a significant percentage of all felony arrestees—one-third to one-half in 2012—are
    57
    not in fact convicted;34 whatever the basis of the initial arrest, many of these arrestees are
    legally innocent of any crime. Yet their DNA profiles remain in the state and federal
    databanks, and their DNA specimens and samples in the DOJ Laboratory indefinitely,
    unless and until they are able to successfully negotiate a lengthy and burdensome
    expungement process that is far from guaranteed to succeed.
    Against this intrusion into individual privacy rights, the governmental interest in
    DNA testing at this early juncture in the criminal process is problematic. The asserted
    interest in identification is undermined by the fact that, unlike fingerprints, DNA cannot
    be processed quickly and used to immediately verify who an arrestee is. The
    investigative use of DNA testing at this stage, however, strains constitutional limitations.
    And DNA testing as early as California permits—before arraignment—appears to be of
    incremental utility at best. The governmental interest advanced most vigorously by
    respondent is the effectiveness of DNA testing in solving crimes. But, the effectiveness
    of a crime fighting technology does not render it constitutional. (See, e.g., City of
    34
    In 2012, 393,439 adult felony arrests were made in California. (Crime in
    California 2012, supra, at p. 19 .) Convictions resulted in 202,413 of these cases; the
    remainder resulted in dismissals or acquittals, denial of prosecutorial complaints, or law
    enforcement releases. (Id. at p. 49.) These convictions accounted for 68.5 percent of all
    final adult felony dispositions (ibid.), meaning that of all the adult felony arrests in 2012
    that reached final disposition, slightly more than two thirds were convicted. The final
    disposition data does not account for all the adult felony arrests made in a year, as it does
    not include intermediate dispositions, diversion programs, suspended proceedings,
    reopenings, retrials, and subsequent actions. (Id. at p. 64.) Comparing the number of
    convictions (202,413) to the total number of arrests (393,439), only 51 percent of those
    arrested were convicted—that is, almost half the adult felony arrestees in 2012 were not
    convicted.
    Respondent points out that the category of arrestees who were not convicted may
    include some who did in fact commit a crime. One example is an arrestee whose
    offenses result in revocation of probation rather than a new criminal prosecution; in 2012,
    47,670 adults had probation revoked for a felony offense. (Crime in California 2012,
    supra, at p. 55.) Many of these arrestees, however, would have been subject to DNA
    testing when they were originally convicted. Arrestees whose cases are not pursued by
    the prosecutor for reasons such as inadmissible evidence or witnesses declining to testify,
    as respondent suggests, may in fact have committed crimes, but they are legally innocent.
    58
    Indianapolis v. Edward, supra, 531 U.S. at p. 42, Ferguson v. City of Charleston (2001)
    
    532 U.S. 67
    , 83-84.) As Chief Justice Traynor put it, “a search, whether incident to an
    arrest or not, cannot be justified by what it turns up.” (People v. Brown (1955) 
    45 Cal.2d 640
    , 643.) It has been stated, with respect to the federal Constitution, that because “[t]he
    interests in human dignity and privacy which the Fourth Amendment protects forbid any
    such intrusion on the mere chance that desired evidence might be obtained” (Schmerber,
    
    supra,
     384 U.S. at pp. 769-770), “the mere fact that law enforcement may be made more
    efficient can never by itself justify disregard of the Fourth Amendment” (Mincey v.
    Arizona (1978) 
    437 U.S. 385
    , 393; Arizona v. Gant, supra, 556 U.S. at p. 349). This is
    all the more obvious under the California Constitution, which expressly recognizes a
    right to privacy, and even more so in the context of a search of such deeply personal and
    private information as is contained in a DNA sample.35
    35
    In fact, if crime solving is the primary goal of the DNA Act, as appears to be
    the case, it is questionable whether its application will continue to be limited, or should
    be limited to felony arrestees and offenders. We take no position on the issue but think it
    appropriate to point out that some who have thought deeply about these questions believe
    DNA should be collected from everyone; and not just because it would make DNA
    databases as comprehensive as possible. (See, DNA Databases, supra, 2003 Wis. L.Rev.
    at pp. 451-452.) It is claimed universal DNA testing would:
    (1) Eliminate the disproportionate representation of racial minorities in the
    database, making it fairer than sampling only offenders and arrestees (DNA Databases,
    supra, 2003 Wis. L.Rev. at pp. 439-440; Lynch et al., Truth Machine (2008) p. 153
    [noting views regarding suggestions to expand United Kingdom’s database]; Nydick,
    Comment: The British Invasion (of Privacy): DNA Databases in the United Kingdom
    and United States in the Wake of the Marper Case (2009) 23 Emory Int’l L.Rev. 609,
    640).
    (2) Obviate or mitigate concerns regarding “pretextual arrests to acquire DNA”
    and “kinship trawling.” (Kaye, Response: Maryland v. King: Per Se Unreasonableness,
    the Golden Rule, and the Future of DNA Databases (2013) 127 Harv. L.Rev. F. 39, 47
    (Future of DNA Databases).)
    (3) Heighten public attention to the use of DNA databases and the vigilance of
    regulators (DNA Databases, supra, 2003 Wis. L.Rev. at p. 422, fn. 29, quoting Cole,
    Fingerprint Identification and the Criminal Justice System: Lessons for the DNA Debate,
    in Lazer, The Technology of Justice: The Use of DNA in the Criminal Justice System
    (2004).) Subjecting everyone—not just those perceived as criminals—to the risk of
    59
    For the reasons we have set forth, we conclude 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.
    The judgment is reversed.

    accidental or intentional misuse of his or her DNA information and samples would
    undoubtedly improve administration of the program. As has been pointed out, “[i]t is too
    easy to approve of taking DNA from arrestees (or any group) when we presume that we
    will not be one of ‘them.’ But if ‘we’ truly conceive of ourselves as the recipients of this
    treatment, then we are more likely to arrive at a system with sufficient safeguards.”
    (Future of DNA Databases, supra, 127 Harv. L.Rev. F. at p. 47.)
    We raise these issues only to show that serious students of DNA sampling—
    virtually all of whom acknowledge that the chief purpose of the practice is criminal
    investigation, not identification—recognize the significant dangers it presents and the
    need to address them more forthrightly and efficaciously than does the DNA Act.
