    JUSTICE BOLICK authored the opinion of the Court, in which CHIEF
    JUSTICE BALES and JUSTICE TIMMER joined. VICE CHIEF JUSTICE
    PELANDER, joined by JUSTICE BRUTINEL, concurred in part and
    dissented in part.
    JUSTICE BOLICK, opinion of the Court:
    ¶1              This case considers the constitutionality of A.R.S. § 28-
    1321(C), the “unconscious clause,” which allows law enforcement officials
    to make or direct nonconsensual blood draws from unconscious DUI
    suspects. We hold that the provision is unconstitutional as applied to the
    facts of this case.
    ¶2             We also consider whether the good-faith exception to the
    exclusionary rule applies here. Following a collision after which defendant
    was airlifted to Nevada, a blood draw was taken at the request of Arizona
    law enforcement officials, raising the question, unresolved in the trial or
    appeals court, of which state’s law applies to decide whether the blood test
    results should be suppressed. We hold that under Arizona law, the good-
    faith exception would not apply, and thus if our state’s law applies, the
    evidence from the blood draw must be suppressed. However, we remand
    to the trial court to determine which jurisdiction’s law applies and, if it is
    Nevada law, whether it supports application of the good-faith exception.

    ¶3             On September 17, 2012, Don Jacob Havatone drove his SUV,
    with four other passengers, into an oncoming vehicle on Route 66 northeast
    of Kingman. A witness driving behind Havatone testified that before the
    collision the SUV was driving “erratically” for several miles and repeatedly
    crossed the center line. The other vehicle was occupied only by its driver,
    2
    STATE V. HAVATONE
    Opinion of the Court
    L.S. After the collision, L.S. saw a man with his foot caught in the SUV’s
    windshield crawl out over the hood and lie down in front of the vehicle.
    She saw a second occupant, later identified as Havatone, exit the driver’s
    side of the SUV and lie down behind the vehicle.
    ¶4           Department of Public Safety (“DPS”) Officer M.P. responded
    to the scene. He approached Havatone, whom medics were treating.
    Havatone confirmed he was driving the SUV. When M.P. asked Havatone
    what happened, Havatone did not respond. M.P. detected a “heavy odor”
    of alcohol emanating from all the SUV’s occupants, including Havatone.
    M.P. looked inside the SUV and saw numerous beer cans and an open bottle
    of liquor.
    ¶5           Havatone was airlifted to a Las Vegas hospital for treatment.
    Without seeking a warrant, Officer M.P. followed DPS policy and
    instructed DPS dispatch to request that Las Vegas police officers obtain a
    blood sample. Havatone was unconscious when the blood sample was
    taken. The sample showed a blood alcohol concentration (“BAC”) of 0.212.
    ¶6            The State charged Havatone with driving under the influence
    of intoxicating liquor while his license was suspended or revoked,
    aggravated driving under the extreme influence of intoxicating liquor with
    a BAC of 0.20 or more with a suspended license, aggravated assault of L.S.
    with a deadly weapon or dangerous instrument, recklessly endangering
    L.S. with a substantial risk of imminent death, and four counts of
    aggravated assault of the occupants of his vehicle with a deadly weapon or
    dangerous instrument.
    ¶7            Havatone moved to suppress the blood test results, arguing
    that the test was a warrantless search prohibited by the Fourth
    Amendment. The trial court denied the motion, finding the search
    permissible under both Arizona and Nevada law because the police had
    probable cause to believe that Havatone was driving while intoxicated and
    both states’ “implied consent” laws authorize blood draws from
    unconscious DUI suspects. See A.R.S. § 28-1321(C); Nev. Rev. Stat.
    § 484C.160(1), (3). Alternatively, the court ruled that even if a warrant was
    required, the police acted in reliance on statutes and cases in effect when
    the blood was seized, thus satisfying the good-faith exception to the
    3
    STATE V. HAVATONE
    Opinion of the Court
    exclusionary rule.
    ¶8           The jury found Havatone guilty of four offenses as charged
    and guilty of lesser included offenses for other charges. The trial court
    imposed concurrent sentences of 17.5 years in prison.
    ¶9           On appeal, Havatone argued that the statute authorizing his
    blood draw while unconscious violated his Fourth Amendment rights. The
    court of appeals affirmed. It did not reach the constitutional question but
    reasoned that even if the blood draw violated Havatone’s Fourth
    Amendment rights, it was shielded by the good-faith exception to the
    exclusionary rule. State v. Havatone, 1 CA-CR 14-0223, at *5 ¶ 20, *6 ¶ 25
    (Ariz. App. Oct. 27, 2015) (“[T]he search was objectively reasonable in either
    state, so we—like the trial court—need not decide whether Arizona or
    Nevada law applies.”).
    ¶10            We granted review because the issues presented are of first
    impression and statewide importance. We have jurisdiction under article
    6, section 5(3) of the Arizona Constitution and A.R.S. § 12-120.24.
    II.
    ¶11            We review rulings on motions to suppress for an abuse of
    discretion, considering only the evidence presented at the suppression
    hearing and viewing it in the light most favorable to sustaining the trial
    court’s ruling. State v. Butler, 
    232 Ariz. 84
    , 87 ¶ 8, 
    302 P.3d 609
    , 612 (2013).
    “An error of law constitutes an abuse of discretion.” State v. Bernstein, 
    237 Ariz. 226
    , 228 ¶ 9, 
    349 P.3d 200
    , 202 (2015). Both a statute’s constitutionality
    under the Fourth Amendment and the applicability of the good-faith
    exception to the exclusionary rule are questions of law that we decide de
    novo. Gallardo v. State, 
    236 Ariz. 84

    ¶12           Arizona’s “implied consent” statute, A.R.S. § 28-1321, reads
    in pertinent part:
    4
    STATE V. HAVATONE
    Opinion of the Court
    A. A person who operates a motor vehicle in this state gives
    consent . . . to a test or tests of the person’s blood, breath,
    urine or other bodily substance for the purpose of
    determining alcohol concentration or drug content if the
    person is arrested for any offense arising out of acts alleged to
    have been committed . . . while the person was driving or in
    actual physical control of a motor vehicle while under the
    influence of intoxicating liquor or drugs. The test or tests
    chosen by the law enforcement agency shall be administered
    at the direction of a law enforcement officer having
    reasonable grounds to believe that the person was driving or
    in actual physical control of a motor vehicle in this state . . .
    (1) [while] under the influence of intoxicating liquor or drugs.
    ....
    C. A person who is dead, unconscious or otherwise in a
    condition rendering the person incapable of refusal is deemed
    not to have withdrawn the consent provided by subsection
    A....
    Subsection C, at issue here, is known as the “unconscious clause.”
    ¶13          After we granted review, the State acknowledged that the
    unconscious clause is unconstitutional as applied to the facts of the case.
    The State takes the position that blood may be taken from a DUI suspect
    under the unconscious clause only if case-specific exigent circumstances
    exist. We agree.
    ¶14          A blood draw taken or directed by the government implicates
    privacy rights protected by the Constitution. The Fourth Amendment
    provides,
    The right of the people to be secure in their persons, houses,
    papers, and effects, against unreasonable searches and
    seizures, shall not be violated, and no warrants shall issue, but
    upon probable cause, supported by oath or affirmation, and
    particularly describing the place to be searched, and the
    5

    Opinion of the Court
    persons or things to be seized.
    U.S. Const. amend. IV. 1
    ¶15            In Missouri v. McNeely, 
    133 S. Ct. 1552
    (2013), decided after the
    arrest here, the United States Supreme Court considered the
    constitutionality of nonconsensual, warrantless blood draws in DUI cases
    where police relied solely upon the natural dissipation of alcohol in the
    blood. Such a “compelled physical intrusion” beneath the skin and into the
    veins “to obtain a sample of his blood for use as evidence in a criminal
    investigation . . . implicates an individual’s ‘most personal and deep-rooted
    expectations of privacy.’” 
    Id. at 1558
    (citation omitted). The Court
    confirmed the view, expressed in prior cases, that such searches could be
    justified only by exigent circumstances. “In short,” the Court ruled, “while
    the natural dissipation of alcohol in the blood may support a finding of
    exigency in a specific case, . . . it does not do so categorically. Whether a
    warrantless blood test of a drunk-driving suspect is reasonable must be
    determined case by case based on the totality of the circumstances.” 
    Id. at 1563.
    ¶16           Following McNeely, we ruled in State v. Butler that Arizona’s
    implied consent statute, A.R.S. § 28-1321, does not relieve the state of
    establishing voluntary consent or another exception to the warrant
    requirement, such as exigent circumstances, to justify warrantless blood
    draws from DUI 
    suspects. 232 Ariz. at 87
    –88 ¶¶ 12–13, 
    18, 302 P.3d at 612
    –
    13. Furthermore, in Birchfield v. North Dakota, 
    136 S. Ct. 2160
    , 2180 (2016),
    the United States Supreme Court noted that the exigency exception “always
    requires case-by-case determinations.”
    ¶17           McNeely and Butler establish that absent an exception to the
    warrant requirement, nonconsensual, warrantless blood draws from DUI
    suspects are unconstitutional. We conclude that the unconscious clause can
    1 Article 2, section 8 of the Arizona Constitution also provides, “No person
    shall be disturbed in his private affairs, or his home invaded, without
    authority of law.” Havatone did not invoke his rights under this provision.
    6
    STATE V. HAVATONE
    Opinion of the Court
    be constitutionally applied only when case-specific exigent circumstances
    prevent law enforcement officers from obtaining a warrant. Here, the State
    concedes that exigent circumstances did not exist. Rather, Officer M.P.
    testified he was following department practice to procure a blood draw
    anytime a DUI suspect was sent out of state for emergency treatment.
    Because the test was taken pursuant to a blanket policy rather than the
    presence of case-specific exigent circumstances, Havatone’s Fourth
    Amendment rights were violated.
    ¶18            Our decision does not vitiate § 28-1321(C). Where police have
    probable cause to believe a suspect committed a DUI, a nonconsensual
    blood draw from an unconscious person is constitutionally permissible if,
    under the totality of the circumstances, law enforcement officials
    reasonably determine that they cannot obtain a warrant without significant
    delay that would undermine the effectiveness of the testing. Cf. 
    McNeely, 133 S. Ct. at 1561
    (noting that “where police officers can reasonably obtain
    a warrant before a blood sample can be drawn without significantly
    undermining the efficacy of the search, the Fourth Amendment mandates
    that they do so”).
    III.
    ¶19           Although the dissent attempts gamely to resuscitate the
    argument, ¶ 40, the State expressly concedes that the record “does not show
    exigent circumstances beyond the natural dissipation of alcohol in
    Appellant’s blood.” Hence, the search violated the Fourth Amendment and
    the only issue is whether the good-faith exception to the exclusionary rule
    applies. Cf. State v. Valenzuela, 
    239 Ariz. 299
    , 309 ¶ 31, 
    371 P.3d 627
    , 637
    (2016) (“[W]hen law enforcement officers act with an objectively reasonable
    good-faith belief that their conduct is lawful, deterrence is unnecessary and
    the exclusionary rule does not apply.”). To resolve that issue, we must
    decide whether before McNeely, DPS reasonably applied a policy of
    directing warrantless blood draws from unconscious DUI suspects being
    flown out of state for medical treatment based on the belief that the natural
    dissipation of alcohol in the blood constituted a per se exigency. The State
    bears the burden of proving the good-faith exception applies. See, e.g.,
    
    Crowley, 202 Ariz. at 91
    32, 41 P.3d at 629
    .
    7
    STATE V. HAVATONE
    Opinion of the Court
    ¶20           The State argues that the blood test results should not be
    suppressed for two reasons: (1) at the time of the blood draw here, the
    unconscious clause expressly authorized the blood draw and had not been
    ruled unconstitutional; and (2) nonconsensual, warrantless blood draws
    were permitted based on natural alcohol dissipation in the blood prior to
    McNeely, which was not decided until after Havatone’s blood was taken.
    For those reasons, the State asserts that the blood draw satisfies the good-
    faith exception to the exclusionary rule. We disagree. DPS should have
    known that routinely directing blood draws from DUI suspects who were
    sent out of state for emergency treatment, without making a case-specific
    determination whether a warrant could be timely secured, was either
    impermissible or at least constitutionally suspect. Thus, the good-faith
    exception does not apply.
    ¶21            The dissent suggests that the good-faith exception applies
    unless the police officers exhibit deliberate, reckless, or grossly negligent
    disregard for Fourth Amendment rights. See ¶ 50 (citing Davis v. United
    States, 
    564 U.S. 229
    , 240 (2011)). Because the exclusionary rule also serves
    to deter “recurring or systemic negligence,” the good-faith exception will
    not apply in such circumstances. See Herring v. United States, 
    555 U.S. 135
    ,
    144 (2009); see also 
    Davis, 564 U.S. at 239
    (relying on Herring in concluding
    that isolated, nonrecurring police negligence “lacks the culpability required
    to justify the harsh sanction of exclusion”). Such “recurring or systemic
    negligence” is present in this case.
    ¶22           Here, the officer followed DPS policy and training that
    seeking a warrant was unnecessary under the circumstances. When the
    Fourth Amendment violation occurred not as the result of an officer’s fact-
    specific determination that obtaining a warrant is infeasible but pursuant
    to department practice making such determination unnecessary, we impute
    to the law enforcement agency the responsibility to assure that unlawful
    seizures will not occur. See 
    Davis, 564 U.S. at 240
    (contrasting “‘recurring
    or systemic negligence’ on the part of law enforcement,” with conduct that
    “involves only simple, ‘isolated’ negligence”). “We should reasonably
    presume that law enforcement officials, who stand in the best position to
    monitor such errors as occurred here, can influence mundane
    communication procedures in order to prevent those errors. That
    presumption comports with the notion that the exclusionary rule exists to
    8
    STATE V. HAVATONE
    Opinion of the Court
    deter future police misconduct systemically.” Arizona v. Evans, 
    514 U.S. 1
    ,
    21 (1995) (Stevens, J., dissenting) (citing, inter alia, Stone v. Powell, 
    428 U.S. 465
    , 492 (1976)); accord State v. Mitchell, 
    234 Ariz. 410
    , 419 ¶ 31, 
    323 P.3d 69
    ,
    78 (App. 2014) (good-faith exception provides “meaningful deterrence
    because . . . it incentivizes law enforcement to err on the side of
    constitutional behavior”). Suppression of the blood test results here will
    have a deterrent effect on police practices that fail to take individual
    circumstances into account as the United States Supreme Court has long
    required. Cf. Ybarra v. Illinois, 
    444 U.S. 85
    , 87, 96 (1979) (striking down
    statute allowing officers to detain or search any persons in premises subject
    to a search warrant, holding such searches must be based on individual
    circumstances); Richards v. Wisconsin, 
    520 U.S. 385
    , 387–88 (1997)
    (invalidating per se rule that no knock to announce police presence is
    permissible in drug warrant cases).
    ¶23           The record here shows that the DPS officer followed the
    department’s regular practice, in which he was trained, to request blood
    draws without a warrant whenever a DUI suspect was flown out of state
    for treatment. As the dissent aptly puts it, DPS was acting on the belief that
    the dissipation of alcohol in the blood created a “per se exigency” that,
    before McNeely, ostensibly justified blood draws from DUI suspects. ¶ 57.
    ¶24            That belief was mistaken.        Davis instructs that law
    enforcement acts in good faith if “binding appellate precedent specifically
    authorizes a particular police 
    practice.” 564 U.S. at 241
    . But warrantless
    blood draws from DUI suspects based on a “per se exigency” rather than
    the totality of individual circumstances have been discredited for over fifty
    years. In Schmerber v. California, 
    384 U.S. 757
    (1966), the United States
    Supreme Court upheld admission of a blood test taken from a defendant
    whom police had probable cause to believe had committed a DUI offense.
    The Court observed, “Search warrants are ordinarily required for searches
    of dwellings, and absent an emergency, no less could be required where
    intrusions into the human body are concerned.” 
    Id. at 770
    (emphasis
    added).
    ¶25          The dissent suggests that the emergency in Schmerber was
    based on the natural dissipation of alcohol in the blood—that is, a per se
    exigency—rather than individualized circumstances making a warrant
    9
    STATE V. HAVATONE
    Opinion of the Court
    untenable. ¶ 53. It was not. The Court concluded that the emergency
    justifying the warrantless, nonconsensual blood draw was based on the
    “special facts” of the case, “where time had to be taken to bring the accused
    to the hospital and to investigate the scene of the accident,” thus “there was
    no time to seek out a magistrate and secure a warrant.” 
    Id. at 770
    –71.
    ¶26           It is true that alcohol dissipation starts a fast time clock, but
    under Schmerber, additional facts are necessary to show it was not feasible
    to obtain a warrant during that time frame. As McNeely observes, in the
    decades since Schmerber, technology has made it possible to quickly obtain
    warrants by phone or 
    otherwise. 133 S. Ct. at 1561
    –63. The State does not
    allege any such “special facts” justifying a warrantless blood draw. Indeed,
    the State concedes that no exigency existed apart from the ordinary
    dissipation of alcohol in the blood, and the DPS officer testified that
    telephonic warrants are possible but he was trained to not obtain a warrant
    when a DUI suspect is airlifted out of state.
    ¶27           The Court in McNeely emphasized that it did not announce a
    new constitutional rule but rather reaffirmed Schmerber’s emergency
    requirement. “[I]n Schmerber, we considered all of the facts and
    circumstances of the particular case and carefully based our holding on
    those specific facts.” 
    McNeely, 133 S. Ct. at 1560
    ; see also 
    id. at 1559
    (“Our
    decision in Schmerber applied this totality of the circumstances approach”);
    
    id. at 1561
    (courts should “decide each case on its facts, as we did in
    Schmerber”). A per se rule that warrants are never required is at
    considerable odds with the Schmerber rule that warrants are required absent
    special facts. Hence, the routine practice of directing blood draws in a
    particular context, where no exigent circumstances existed, was
    impermissible at the time Havatone was arrested.
    ¶28            The State argues that the good-faith exception applies because
    § 28-1321(C) had not been declared unconstitutional when Havatone’s
    blood was taken. Cf. Illinois v. Krull, 
    480 U.S. 340
    , 355 (1987) (“Nor can a
    law enforcement officer be said to have acted in good-faith reliance upon a
    statute if its provisions are such that a reasonable officer should have
    known that the statute was unconstitutional.”). Nor do we declare it
    unconstitutional here in all respects. See ¶ 18. But Schmerber’s special facts
    rule was known, thereby rendering legally untenable the routine practice
    10
    STATE V. HAVATONE
    Opinion of the Court
    of warrantless blood draws from unconscious DUI suspects transported to
    other states for medical purposes. And no binding precedents specifically
    authorized such a practice. Arizona case law regarding a per se exigency
    was, at most, unsettled.
    ¶29            When the law is unsettled, “exclusion of the evidence
    obtained” in a questionable search or seizure “may deter Fourth
    Amendment violations.” 
    Davis, 564 U.S. at 250
    (Sotomayor, J., concurring
    in the judgment); accord United States v. Lara, 
    815 F.3d 605
    , 613 (9th Cir. 2016)
    (“We decline to expand the rule of Davis to cases in which the appellate
    precedent, rather than being binding, is (at best) unclear.”). As the Court
    observed in United States v. Johnson, if the exclusionary rule is not applied
    in “close” cases, “law enforcement officials would have little incentive to
    err on the side of constitutional behavior. Official awareness of the dubious
    constitutionality of a practice would be counterbalanced by official
    certainty that, so long as the Fourth Amendment law in the area remained
    unsettled, evidence obtained through the questionable practice” would not
    be excluded. 
    457 U.S. 537
    , 561 (1982); accord 
    Mitchell, 234 Ariz. at 419
    31, 323 P.3d at 78
    . Similarly, Justice O’Connor warned in Krull that “the failure
    to apply the exclusionary rule in the very case in which a state statute is
    held to have violated the Fourth Amendment destroys all incentive on the
    part of individual criminal defendants to litigate the violation of their
    Fourth Amendment 
    rights.” 480 U.S. at 369
    (O’Connor, J., dissenting).
    ¶30            Arizona case law in effect at the time of Havatone’s blood test
    did not “specifically authorize[] a particular police practice,” see 
    Davis, 564 U.S. at 241
    (emphasis omitted), of directing warrantless, nonconsensual
    blood draws from unconscious DUI suspects absent exigent circumstances.
    In State v. Cocio, 
    147 Ariz. 277
    , 
    709 P.2d 1336
    (1985), we held that a formal
    arrest was not necessary for police to obtain a blood sample from a DUI
    suspect drawn by medical personnel for treatment purposes. We applied
    Schmerber as recognizing exigent circumstances based on dissipation of
    alcohol in the blood.

    A.R.S. § 28-692(M) (renumbered 28-1388(E)), which allowed police to
    obtain medical blood samples, together with applicable United States

    probable cause exists to believe the suspect has violated DUI laws, (2)
    “exigent circumstances are present,” and (3) “the blood is drawn for
    11

    Opinion of the Court
    medical purposes by medical personnel.” 
    Id. at 286,
    709 P.2d at 1345. We
    recently rejected any suggestion that Cocio established that alcohol in the
    bloodstream constitutes a per se exigency. See State v. Nissley, 
    241 Ariz. 327
    ,
    330 ¶ 11, 
    387 P.3d 1256
    , 1259 (2017) (holding the dissipation of alcohol in
    the blood does not create a per se exigency, but otherwise leaving the Cocio
    decision intact). 2     But even before this clarification, Cocio was
    distinguishable because it did not involve a government-directed blood
    draw, but was limited to the medical draw exception, where the state
    obtains a portion of blood already drawn for medical reasons. See 
    Cocio, 147 Ariz. at 286
    –87, 709 P.2d at 1345–46 (“[T]he intrusion by the police was
    minimal. The blood extraction was not performed at the request of the
    police, but pursuant to the orders of the attending physician for medical
    purposes. Thus, the intrusion by the police in this case was not the needle
    puncture and the insertion of the needle into the vein, but merely a
    sampling off of an additional portion of the defendant’s blood.”). Whatever
    police conduct Cocio “specifically authorized,” as the Court there made
    clear, was limited to the less-invasive state action at issue in that case.
    ¶31           In State v. Huffman, 
    137 Ariz. 300
    , 302, 
    670 P.2d 405
    , 407 (App.
    1983), the court of appeals held that no arrest is necessary for a blood draw
    under the unconscious exception. The court applied Schmerber, holding
    that a warrantless, nonconsensual blood draw from an unconscious DUI
    suspect requires probable cause “and that the officer might reasonably
    believe that he is confronted with an emergency so that the delay necessary
    to obtain a warrant, under the circumstances, threatens destruction of the
    evidence.” 
    Id. at 302–03,
    670 P.2d at 407–08. Far from specifically
    authorizing a per se rule, Huffman properly interpreted Schmerber to require
    an individualized, totality of the circumstances determination.
    2 The dissent also cites Campbell v. Superior Ct., 
    106 Ariz. 542
    , 554, 
    479 P.2d 685
    , 696 (1971), for the proposition that this Court found “no merit” to a
    constitutional challenge to the implied consent law. The Campbell Court’s
    analysis is two sentences, and appears to comprise a facial challenge to the
    whole statute, which we agree is not facially unconstitutional. Certainly it
    does not remotely amount to the specific appellate court authorization
    required to find good faith under Davis.
    12
    STATE V. HAVATONE
    Opinion of the Court
    ¶32           In State v. Flannigan, 
    194 Ariz. 150
    , 152 ¶ 9, 
    978 P.2d 127
    , 129
    (App. 1998), police officers directed a blood draw from a DUI suspect
    relying on “the department’s policy that exigent circumstances always exist
    in vehicular aggravated assault and manslaughter cases.” Although the
    case involved a different statute, the court of appeals analyzed Schmerber’s
    exigent circumstances rule as we do here:
    In Schmerber, exigent circumstances existed because of the
    evanescent quality of alcohol and because the police
    reasonably believed that they did not have time to “seek out
    a magistrate and secure a warrant” before evidence of the
    defendant’s intoxication would be destroyed. Schmerber does
    not provide a blanket exception to the warrant requirement
    whenever a suspect is believed to be under the influence of
    alcohol or drugs. Rather, the evanescent quality of alcohol
    and drugs in a person’s body creates an exigency only if the
    evidence might disappear before the police can obtain a
    warrant.
    
    Id. at 154
    20, 978 P.2d at 131
    . The court aptly concluded, “The officers’
    rote application of the department’s untenable policy . . . violated
    Flannigan’s right to be free from unreasonable search and seizure.” 
    Id. at 155
    25, 978 P.2d at 132
    .
    ¶33           Here, the officer’s “rote application” of department policy to
    obtain warrantless, nonconsensual blood draws from DUI suspects who are
    transported to another state for medical treatment was inconsistent with
    federal and state appellate precedents, and certainly was not “specifically
    authorized.”
    ¶34          For those reasons, DPS’s practice of directing routine,
    warrantless, nonconsensual blood draws from DUI suspects sent outside
    the state for medical treatment was not objectively reasonable under
    Arizona law at the time of the draw. Therefore, the trial and appeals courts
    erred as a matter of Arizona law in concluding that the State satisfied its
    burden of proving that the impermissible blood draw was justified by the
    good-faith exception to the exclusionary rule.
    13
    STATE V. HAVATONE
    Opinion of the Court
    ¶35            The dissent asserts that our decision “risks ‘set[ting] the
    criminal loose in the community without punishment.’” ¶ 63. As in any
    case in which law enforcement tactics are measured against constitutional
    protections, this may be the unavoidable result in some DUI cases. But
    other evidence of impaired driving likely exists in such cases that support
    continued prosecution for DUI. Here, evidence of probable cause, and
    hence evidence potentially supporting a guilty verdict, was abundant
    (defendant was the driver, witnesses saw the car driving erratically, the
    officer smelled alcohol, and there were beer cans and a liquor bottle at the
    accident scene). Moreover, A.R.S. § 28-1321(B) provides for suspension of
    a driver’s license where a person arrested for DUI fails to submit to alcohol
    testing. See Carrillo v. Houser, 
    224 Ariz. 463
    , 465–66 ¶ 13, 
    232 P.3d 1245
    ,
    1247–48 (2010); see also 
    McNeely, 133 S. Ct. at 1565
    –67 (plurality) (noting such
    sanctions and concluding that “the government’s interest in this area does
    not justify departing from the warrant requirement without showing
    exigent circumstances that make securing a warrant impractical in a
    particular case”).
    IV.
    ¶36             The parties disagree whether Nevada or Arizona law applies
    to this case. 3 The trial and appeals courts did not resolve the issue because
    they concluded the good-faith exception would apply in either state. The
    parties did not extensively address the issue in this Court. Hence, we
    remand the case to the trial court to determine, in the first instance, whether
    Arizona or Nevada law applies. If the court concludes that Nevada law
    applies, it should determine whether the good-faith exception applies. If
    the good-faith exception does not apply, the trial court must vacate the
    3 Nevada’s implied consent law includes an unconscious clause directing a
    mandatory blood draw, providing that where a DUI suspect “is dead or
    unconscious, the officer shall direct that samples of blood from the person
    [] be tested.” Nev. Rev. Stat. § 484C.160(3). The Nevada Supreme Court
    recently held unconstitutional a different section of the implied consent law
    because it did not allow a DUI suspect to withdraw consent. Byars v. State,
    
    336 P.3d 939
    , 946 (Nev. 2014).

    new trial.
    ¶37           Accordingly, we vacate the court of appeals’ decision, reverse
    the trial court’s decision on the motion to suppress, and remand to that
    court for further proceedings consistent with this opinion.

    STATE V. HAVATONE
    VICE CHIEF JUSTICE PELANDER, joined by JUSTICE BRUTINEL,
    Dissented in part and Concurred in part
    PELANDER, V.C.J., joined by BRUTINEL, J., concurring in part and
    dissenting in part.
    ¶38            For almost fifty years, Arizona’s “implied consent” law has
    specifically and expressly allowed law enforcement to obtain for testing a
    blood sample of a DUI suspect who is unconscious. A.R.S. § 28-1321(C); see
    former A.R.S. § 28-691(C) (1969 Ariz. Sess. Laws ch. 41, § 1). Pursuant to
    that statutory authority, when the events in this case occurred in September
    2012, police officers (and for that matter a conscientious police department
    or its legal counsel) would have reasonably believed that they could obtain,
    without a warrant, a blood sample from an unconscious DUI suspect. That
    is particularly so when, as here, the DUI suspect’s serious injuries required
    him to be airlifted to a hospital across state lines for emergency medical
    treatment.
    ¶39            As of 2012, the warrantless blood draw from the unconscious
    DUI suspect here was permissible because it was authorized under
    Arizona’s implied consent law and was reasonable under the totality of the
    circumstances that the trial court found based on the investigating officer’s
    testimony. Contrary to the majority’s assertion, supra ¶ 20, under the law
    in effect at that time, admissibility of the blood test results did not require
    the state to show that the officer made “a case-specific determination
    whether a warrant could be timely secured.” But even if the majority is
    correct in concluding otherwise, and assuming that Arizona law applies,
    the good-faith exception to the exclusionary rule should apply because the
    blood draw was objectively reasonable and no legitimate purpose is served
    by suppressing the blood evidence in this case.
    ¶40            Based on legal developments that occurred after September
    2012, I agree (and the State concedes) that current law renders § 28-1321(C)
    unconstitutional as applied to this case and that the blood draw from
    Havatone would not comply with Fourth Amendment standards now. I
    also agree that post-2012 cases support the rule of law the majority
    announces regarding future application of the unconscious clause. Supra
    ¶¶ 17-18. But the majority asserts that “the State concedes that exigent
    circumstances did not exist,” supra ¶ 17, when in fact the State expressly
    qualified its “concession” as follows: “Under recent Fourth Amendment
    decisions, [Havatone’s] warrantless blood draw was not justified by either
    16
    STATE V. HAVATONE
    VICE CHIEF JUSTICE PELANDER, joined by JUSTICE BRUTINEL,
    Dissented in part and Concurred in part
    the consent or exigency exceptions. But this was not so on the day officers
    drew blood from an unconscious [Havatone].” 4 Thus, the State merely
    agreed that “[the] blood draw was not reasonable under the exigent
    circumstances exception, as understood today.”
    ¶41            The majority faults the investigating DPS officer for having
    “followed DPS policy and training” in requesting the blood draw. Supra ¶
    22. But the majority’s emphasis on “department practice,” 
    id., a matter
    barely touched on in the suppression hearing, disregards much of the
    officer’s testimony and the trial court’s findings. And we of course must
    view the facts in the light most favorable to sustaining the trial court’s
    ruling. State v. Maciel, 
    240 Ariz. 46
    , 49 ¶ 9, 
    375 P.3d 938
    , 941 (2016).
    ¶42            It is quite clear that Officer M.P. accurately determined that
    Havatone was driving under the influence of alcohol and caused the head-
    on collision that seriously injured himself and others. See supra ¶¶ 4-5, 35.
    Contrary to the majority’s suggestion that the officer “fail[ed] to take
    individual circumstances into account,” supra ¶ 22, at the suppression
    hearing Officer M.P. testified that “exigent circumstances” supported his
    request for the blood draw based on the following factors that he identified:
    a very “chaotic” accident scene that he was responsible for investigating;
    the alcohol-related “serious collision” that resulted in severe injuries to
    Havatone and others; and Havatone (the driver/DUI suspect) being
    transported for emergency medical treatment out of state, where an
    Arizona warrant would have no force or effect. That testimony hardly
    suggests a disregard of circumstances warranting the officer’s blood-draw
    request. Indeed, viewed in the light most favorable to sustaining the trial
    court’s ruling, Officer M.P.’s testimony supported the court’s implicit
    determination that “Schmerber’s emergency requirement” was satisfied.
    Supra ¶ 27.
    ¶43          Based on the evidence presented at the suppression hearing
    4  At oral argument in this Court, the State likewise consistently qualified
    its concession in this same way and merely disclaimed any argument that
    “under McNeely, this case would present exigent circumstances.”
    17
    STATE V. HAVATONE
    VICE CHIEF JUSTICE PELANDER, joined by JUSTICE BRUTINEL,
    Dissented in part and Concurred in part
    and specifically citing the factors to which Officer M.P. testified, the trial
    court expressly found that “the totality of the circumstances” supported the
    officer’s request for a warrantless blood draw. We should defer to the trial
    court’s finding, which was supported by the record and applicable law in
    effect at the time of the blood draw. See Ornelas v. United States, 
    517 U.S. 690
    , 699 (1996) (holding that “as a general matter determinations of
    reasonable suspicion and probable cause should be reviewed de novo on
    appeal,” but that appellate courts should “review findings of historical fact
    only for clear error and . . . give due weight to inferences drawn from those
    facts by resident judges and local law enforcement officers”); cf. Valley
    Medical Specialists v. Farber, 
    194 Ariz. 363
    , 366-67 ¶ 11, 
    982 P.2d 1277
    , 1280-
    81 (1999) (because “reasonableness is a fact-intensive inquiry that depends
    on weighing the totality of the circumstances[,] . . . we will give substantial
    deference both to the trial court’s findings of fact and its application of law
    to fact”).
    ¶44           Assuming that Arizona law applies in this matter, I also
    disagree with the majority’s conclusion that the good faith exception to the
    exclusionary rule does not apply. Rather, I agree with the trial court and
    the unanimous court of appeals that the seizure of Havatone’s blood sample
    was objectively reasonable and that no legitimate purpose is served by
    suppressing the blood evidence in this case. Therefore, the good faith
    exception applies. Accordingly, I respectfully dissent from section III of the
    majority’s opinion and its holding that under Arizona law evidence relating
    to Havatone’s blood sample must be suppressed.
    ¶45           The exclusionary rule bars the prosecution from presenting
    evidence obtained in violation of the Fourth Amendment in certain
    circumstances. Davis v. United States, 
    564 U.S. 229
    , 231-32 (2011). The rule
    is not required under the Fourth Amendment; instead, the Supreme Court
    created the rule to “compel respect for the constitutional guaranty” of that
    amendment. 
    Id. at 236
    (citation omitted). The rule itself is “not a personal
    constitutional right” meant to protect the party whose Fourth Amendment
    right was infringed, but rather its sole purpose is to deter future Fourth
    Amendment violations. 
    Id. at 236
    -37. “Whether the exclusionary sanction
    is appropriately imposed in a particular case . . . is an issue separate from
    the question whether the Fourth Amendment rights of the party seeking to
    invoke the rule were violated by police conduct.” United States v. Leon, 468

    STATE V. HAVATONE
    VICE CHIEF JUSTICE PELANDER, joined by JUSTICE BRUTINEL,
    Dissented in part and Concurred in part
    U.S. 897, 906 (1984).
    ¶46           The good faith exception to the exclusionary rule permits law
    enforcement to reasonably rely on legislative enactments, Illinois v. Krull,
    
    480 U.S. 340
    , 349-50, 358-60 (1987), and binding appellate precedent, 
    Davis, 564 U.S. at 240
    -41. When performing a search pursuant to a legislative
    enactment, “[u]nless [the] statute is clearly unconstitutional, an officer
    cannot be expected to question the judgment of the legislature that passed
    the law.” 
    Krull, 480 U.S. at 349-50
    . Even when the previously accepted
    application of a “statute is subsequently declared unconstitutional,”
    exclusion of evidence obtained under the statute “will not deter future
    Fourth Amendment violations.” 
    Id. at 350.
    “Therefore, when law
    enforcement officers act with an objectively reasonable good-faith belief
    that their conduct is lawful, deterrence is unnecessary and the exclusionary
    rule does not apply.” State v. Valenzuela, 
    239 Ariz. 299
    , 309 ¶ 31, 
    371 P.3d 627
    , 637 (2016) (internal quotation marks and citation omitted); see also
    A.R.S. § 13-3925 (codifying good-faith exception to the exclusionary rule).
    The majority gives scant attention to Krull, a case that directly supports
    application of the good faith exception here (as the court of appeals
    recognized).
    ¶47           “Indiscriminate application of the exclusionary rule . . . may
    well generate disrespect for the law and administration of justice.” 
    Leon, 468 U.S. at 907
    . Only when the benefits of deterrence outweigh the social
    costs, which will include the high cost of excluding reliable, trustworthy
    evidence, should the rule operate. 
    Davis, 564 U.S. at 237
    .
    ¶48           As noted above, law enforcement may reasonably rely on
    statutory authority later declared unconstitutional, 
    Krull, 480 U.S. at 349-50
    ,
    or on binding appellate precedent later overturned, 
    Davis, 564 U.S. at 240
    -
    41. Although either of these disjunctive factors is sufficient to support the
    good faith exception, both exist here. DPS Officer M.P.’s request for
    Nevada authorities to obtain a sample of Havatone’s blood was made
    pursuant to, and in accordance with, Havatone’s implied consent under
    A.R.S § 28-1321(C) and our interpretation of exigent circumstances in State
    v. Cocio, 
    147 Ariz. 277
    , 286, 
    709 P.2d 1336
    , 1345 (1985). As of September
    2012, § 28-1321(C) was presumed to be constitutional, State v. Thompson, 
    204 Ariz. 471
    , 474-75 ¶ 10, 
    65 P.3d 420
    , 423-24 (2003), and Cocio had not been
    19
    STATE V. HAVATONE
    VICE CHIEF JUSTICE PELANDER, joined by JUSTICE BRUTINEL,
    Dissented in part and Concurred in part
    overruled or questioned. Applying the exclusionary rule, therefore,
    provides no deterrent effect justifying suppression of the BAC evidence in
    this case.
    ¶49           The majority holds that “the unconscious clause [in § 28-
    1321(C)] can be constitutionally applied only when case-specific exigent
    circumstances prevent law enforcement officers from obtaining a warrant.”
    Supra ¶ 17; see also 
    id. ¶ 18
    (“[A] nonconsensual blood draw from an
    unconscious person is constitutionally permissible if, under the totality of
    the circumstances, law enforcement officials reasonably determine that
    they cannot obtain a warrant without significant delay that would
    undermine the effectiveness of the testing.”). But as the majority implies,
    supra ¶¶ 15-18, only cases decided by the United States Supreme Court and
    this Court after the events in question here compel or support that
    conclusion. See Missouri v. McNeely, 
    133 S. Ct. 1552
    , 1561 (2013) (concluding
    that “[i]n those drunk-driving investigations where police officers can
    reasonably obtain a warrant before a blood sample can be drawn without
    significantly undermining the efficacy of the search, the Fourth
    Amendment mandates that they do so”); State v. Butler, 
    232 Ariz. 84
    , 88 ¶ 18,
    
    302 P.3d 609
    , 613 (2013) (holding that, “independent of § 28-1321, the Fourth
    Amendment requires an arrestee’s consent to be voluntary to justify a
    warrantless blood draw”).
    ¶50             Those recent cases cannot retroactively support a finding that
    Officer M.P. exhibited “deliberate, reckless, or grossly negligent disregard
    for Fourth Amendment rights” in ordering a blood sample pursuant to
    then-valid § 28-1321(C). 
    Davis, 564 U.S. at 238
    (quoting Herring v. United
    States, 
    555 U.S. 135
    , 144 (2009)). As the Court in Davis observed, the reasons
    for and benefits of exclusion vary based on the culpability of law
    enforcement, and absent deliberate, reckless, or grossly negligent violation
    of Fourth Amendment rights, grounds for exclusion are weak “when the
    police act with an objectively ‘reasonable good-faith belief’ that their
    conduct is lawful.” 
    Id. (quoting Leon,
    468 U.S. at 909); see also 
    Valenzuela, 239 Ariz. at 310
    35, 371 P.3d at 638
    (applying Davis’s standard in finding
    good faith reliance on statutory and case authority). Although the majority
    rests its decision on alleged “recurring or systemic negligence,” supra ¶ 21,
    the good faith exception clearly applies when, as here, law enforcement
    reasonably relies on a facially and presumptively valid statute to govern its

    actions, 
    Krull, 480 U.S. at 349-50
    , a principle the majority essentially ignores.
    ¶51            When the events in question occurred in September 2012, no
    court had suggested, let alone concluded, that § 28-1321(C) was invalid or
    otherwise did not authorize the officer’s conduct. In Campbell v. Superior
    Court, we found “no merit” to the argument that Arizona’s implied consent
    law (which at that time included the predecessor unconscious clause now
    found in § 28-1321(C)) violates the Fourth Amendment. 
    106 Ariz. 542
    , 554,
    
    479 P.2d 685
    , 697 (1971). More recently, we held solely “as a matter of
    statutory interpretation,” not based on constitutional grounds, that
    Arizona’s implied consent law “generally does not authorize law
    enforcement officers to administer [a blood test] without a warrant unless
    the arrestee expressly agrees to the test.” Carrillo v. Houser, 
    224 Ariz. 463
    ,
    463 ¶ 1, 467 ¶ 21, 
    232 P.3d 1245
    , 1245, 1249 (2010). But we expressly
    remarked that the unconscious clause in § 28-1321(C) was “not at issue,”
    and thus we did not address “circumstances in which subsection (C) . . .
    may allow warrantless testing of persons incapable of refusing a test.” 
    Id. at 464
    ¶ 2 n.2, 467 ¶ 
    21, 232 P.3d at 1246
    , 1249.
    ¶52          In short, as of September 2012, no Arizona court had
    suggested that the continued validity of the unconscious clause was
    dubious. Yet the majority unpersuasively suggests that, under the state of
    the law at that time, the provisions of § 28-1321(C) “[were] such that a
    reasonable officer should have known that the statute was
    unconstitutional.” Supra ¶ 28 (quoting 
    Krull, 480 U.S. at 355
    ).
    ¶53           Contrary to the majority’s reasoning, supra ¶¶ 24-27,
    Schmerber v. California, 
    384 U.S. 757
    (1966), neither casts doubt on the pre-
    McNeely validity of § 28-1321(C) nor negates application of the good faith
    exception here. In its discussion of Schmerber, supra ¶¶ 24-25, the majority
    omits a significant portion of the Court’s reasoning in finding that a
    warrantless blood draw from a DUI suspect in that case did not violate the
    Fourth Amendment:
    21
    STATE V. HAVATONE
    VICE CHIEF JUSTICE PELANDER, joined by JUSTICE BRUTINEL,
    Dissented in part and Concurred in part
    The officer in the present case . . . might reasonably have
    believed that he was confronted with an emergency, in which
    the delay necessary to obtain a warrant, under the
    circumstances, threatened ‘the destruction of evidence[.]’ We
    are told that the percentage of alcohol in the blood begins to
    diminish shortly after drinking stops, as the body functions to
    eliminate it from the system. Particularly in a case such as
    this, where time had to be taken to bring the accused to a
    hospital and to investigate the scene of the accident, there was
    no time to seek out a magistrate and secure a warrant. Given
    these special facts, we conclude that the attempt to secure
    evidence of blood-alcohol content in this case was an
    appropriate incident to petitioner's arrest.
    
    Schmerber, 384 U.S. at 770-71
    (citation omitted). Given the similar
    circumstances of this case (with the additional fact here that the injured DUI
    suspect was transported out of state), the DPS officer likewise “might
    reasonably have believed that he was confronted with an emergency” that
    authorized the warrantless blood draw. 
    Id. ¶54 Tellingly,
    the pertinent Arizona cases interpreting and
    applying Schmerber do not support the majority’s analysis and conclusion,
    but instead support application of the good faith exception. In Campbell,
    this Court rejected a Fourth Amendment challenge to Arizona’s implied
    consent law (including the unconscious clause) “in light of the holding in
    
    Schmerber.” 106 Ariz. at 545
    , 
    554, 479 P.2d at 688
    , 697. Later, in Cocio, we
    expounded in greater depth on our understanding of Schmerber:
    The United States Supreme Court in Schmerber held that a
    blood sample may be taken without a search warrant if it is
    taken in a medically approved manner and based on probable
    cause to believe the person is intoxicated. In such a situation
    exigent circumstances permit a warrantless seizure because,
    “. . . the percentage of alcohol in the blood begins to diminish
    shortly after drinking stops, as the body functions to eliminate
    it from the system.”
    22
    STATE V. HAVATONE
    VICE CHIEF JUSTICE PELANDER, joined by JUSTICE BRUTINEL,
    Dissented in part and Concurred in 
    part 147 Ariz. at 285-86
    , 709 P.2d at 1344-45 (quoting 
    Schmerber, 384 U.S. at 770
    ).
    ¶55            To authorize a warrantless blood draw under the medical
    blood draw exception, A.R.S. § 28-1388(E) (former § 28-692(M)), Cocio
    required the presence of “exigent circumstances.” 147 Ariz. at 
    286, 709 P.2d at 1345
    . But we concluded that “exigent circumstances existed” merely
    “because of the destructibility of the evidence.” 
    Id. (citing Schmerber
    for the
    proposition that “[t]he highly evanescent nature of alcohol in the
    defendant’s blood stream guaranteed that the alcohol would dissipate over
    a relatively short period of time”).           Based on that physiological
    phenomenon alone, this Court thus recognized a per se exigency. Stated
    differently, to establish exigency, the State was not required to show that
    there was no time or opportunity to obtain a warrant. Again, that
    additional requirement, first imposed by McNeely and now incorrectly
    applied retroactively by the majority here, did not apply to this case. See
    State v. Reyes, 
    238 Ariz. 575
    , 578-79 ¶ 19, 
    364 P.3d 1134
    , 1137-38 (App. 2015)
    (noting that as of 2012, “Arizona courts had uniformly held that dissipation
    of alcohol in blood was in itself a sufficient exigent circumstance for
    purposes of the medical exception”) (citing Cocio and other cases).
    ¶56             The majority alternatively posits that the law on this point
    “was, at most, unsettled” in September 2012. Supra ¶ 28. Again, I disagree.
    Although Cocio did not address the unconscious clause, its finding of
    exigent circumstances based solely on the “highly evanescent nature of
    alcohol” in the blood and its rapid dissipation rate was not limited to the
    medical blood draw context. 147 Ariz. at 
    286, 709 P.2d at 1345
    . In that
    regard, consistent with Cocio, other courts also viewed Schmerber as broadly
    establishing a per se exigency based on the dissipation factor alone. See
    State v. Shriner, 
    751 N.W.2d 538
    , 547 & n.11 (Minn. 2008) (citing Cocio among
    other cases that interpreted Schmerber “as concluding that the naturally
    rapid dissipation of alcohol in the bloodstream creates an emergency that
    justifies a warrantless blood draw”); State v. Blank, 
    90 P.3d 156
    , 164 n.1
    (Alaska 2004) (Matthew, J., dissenting) (same); People v. Harrison, 
    58 N.E.3d 623
    , 628 (Ill. Ct. App. 2016) (same); see also People v. Harris, 
    184 Cal. Rptr. 3d 198
    , 205 (Cal. App. 2015) (noting that before McNeely, “California courts
    uniformly interpreted Schmerber as permitting forced blood draws based
    solely on probable cause of DUI because the natural dissipation of alcohol
    or drugs in the blood was itself an exigent circumstance”).
    23
    STATE V. HAVATONE
    VICE CHIEF JUSTICE PELANDER, joined by JUSTICE BRUTINEL,
    Dissented in part and Concurred in part
    ¶57             The same exigency we recognized in Cocio, the natural
    dissipation of alcohol, would also be an exigency when, as here, a suspect
    is unconscious. And as we acknowledged in our recent opinion regarding
    the medical blood draw exception (A.R.S. § 28-1388(E)), the 2013 McNeely
    case requires us to disavow Cocio’s statement that “the natural dissipation
    of alcohol in the bloodstream itself establishes a per se exigency that
    authorizes a warrantless blood test,” and to instead announce that “in future
    cases, consistent with McNeely, the state must establish exigency by showing
    that under circumstances specific to those cases, it was impractical to obtain
    a warrant.” State v. Nissley, 
    241 Ariz. 327
    , 330-31 ¶¶ 11-12, 
    387 P.3d 1256
    ,
    1259-60 (2017) (emphasis added). Although I agree that, post-McNeely, “the
    unconscious clause can be constitutionally applied only when case-specific
    exigent circumstances prevent law enforcement officers from obtaining a
    warrant,” supra ¶ 17, no such showing was required as of 2012.
    ¶58            The majority’s reliance on two court of appeals cases is even
    more curious. Supra ¶¶ 31-32. The majority correctly observes that the
    court in State v. Huffman “applied Schmerber,” supra ¶ 31, but disregards the
    Huffman court’s statement that under Schmerber the natural dissipation of
    alcohol in blood justified officers in taking a blood sample from the
    unconscious DUI suspect pursuant to the implied consent statute’s
    unconscious clause. 
    137 Ariz. 300
    , 303, 
    670 P.2d 405
    , 408 (App. 1983). The
    court thus affirmed the denial of Huffman’s motion to suppress even absent
    any other evidence of exigency or any showing that the officer could not
    have obtained a warrant.
    ¶59           State v. Flannigan, on which the majority also relies, supra ¶ 32,
    is inapposite. 
    194 Ariz. 150
    , 
    978 P.2d 127
    (App. 1998). That case involved a
    driver’s methamphetamine (not alcohol) use and negligent-homicide
    conviction under Title 13, not DUI charges under Title 28; and Flannigan did
    not even “involve an application of the Arizona implied consent statute.”
    
    Id. at 152-53
    13, 978 P.2d at 129-30
    . Nor did the case involve either the
    unconscious clause at issue here or the medical blood draw exception,
    which the court recognized “would have entitled the police to receive a
    sample of [the suspect’s] blood regardless of his consent.” 
    Id. at 153
    14, 978 P.2d at 130
    . As our court of appeals recently and correctly observed,
    “Flannigan did not signal a shift away from Cocio” and “did not vitiate Cocio,
    24
    STATE V. HAVATONE
    VICE CHIEF JUSTICE PELANDER, joined by JUSTICE BRUTINEL,
    Dissented in part and Concurred in part
    nor could it.” 
    Reyes, 238 Ariz. at 578
    18, 364 P.3d at 1137
    . To the extent
    Flannigan’s reading of Schmerber deviated from Cocio, which the Flannigan
    court did not even cite, Cocio controls. Lind v. Superior Court, 
    191 Ariz. 233
    ,
    237 ¶ 20, 
    954 P.2d 1058
    , 1062 (App. 1998) (recognizing that court of appeals
    is “bound by our supreme court’s determinations”).
    ¶60            Because the seizure of a blood sample from Havatone while
    he was unconscious and receiving emergency medical treatment in another
    state was specifically authorized by a longstanding statute that no court had
    even questioned, much less ruled invalid, it matters not that Officer M.P.’s
    actions were taken pursuant to his DPS training or department policy. That
    training and policy were permissible under Arizona law, which Officer
    M.P. had no reason to question. Just as the officer had no reason to question
    the constitutionality of the statute based on then-existing law, he likewise
    had no reason to question the validity of the department’s policy. Whether
    Officer M.P. “might reasonably have believed that he was confronted with
    an emergency” that authorized the warrantless blood draw under the
    statute, or under the department’s policy, should not matter. 
    Schmerber, 384 U.S. at 770
    ; see State v. Dennis, 
    300 P.3d 81
    , 83 (Kan. 2013) (holding that “it
    was unnecessary for the officer to specifically articulate [a state statute] as
    authority for the [warrantless] search because application of a good-faith
    exception to the exclusionary rule is not governed by a subjective inquiry.
    The question is whether an objectively reasonable officer could rely on [the
    statute].”). The majority does not persuasively establish otherwise.
    ¶61            “[T]he ultimate touchstone of the Fourth Amendment is
    ‘reasonableness.’” Brigham City v. Stuart, 
    547 U.S. 398
    , 403 (2006). “An
    action is ‘reasonable’ under the Fourth Amendment, regardless of the
    individual officer’s state of mind, ‘as long as the circumstances, viewed
    objectively, justify [the] action.’” 
    Id. at 404
    (quoting Scott v. United States,
    
    436 U.S. 128
    , 138 (1978)) (emphasis and alteration in Stuart); cf. Heien v.
    North Carolina, 
    135 S. Ct. 530
    , 534, 539 (holding that an officer’s mistake of
    law can give rise to the reasonable suspicion necessary to uphold a seizure
    under the Fourth Amendment and noting that in determining whether a
    mistake of fact or law was objectively reasonable, “[w]e do not examine the
    subjective understanding of the particular officer involved”).
    ¶62           Applying that standard here, contrary to the majority’s
    25
    STATE V. HAVATONE
    VICE CHIEF JUSTICE PELANDER, joined by JUSTICE BRUTINEL,
    Dissented in part and Concurred in part
    conclusion, Officer M.P’s request for Nevada authorities to obtain a sample
    of Havatone’s blood indeed was “objectively reasonable under Arizona law
    at the time of the draw.” Supra ¶ 34. The officer certainly did not
    “deliberately, recklessly, or with gross negligence” violate Havatone’s
    Fourth Amendment rights in requesting the blood draw. 
    Davis, 346 U.S. at 240
    . Therefore, given the “nonculpable, innocent police conduct” here, 
    id., the good
    faith exception to the exclusionary rule applies. See 
    Valenzuela, 239 Ariz. at 310
    35, 371 P.3d at 638
    (finding good faith exception applied when
    officer “did not ‘deliberately, recklessly, or with gross negligence’ conduct
    the search in violation of the Fourth Amendment, but instead acted with
    ‘an objectively reasonable good-faith belief’ that the admonition was
    lawful”) (quoting 
    Davis, 131 S. Ct. at 2427-28
    ); 
    Reyes, 238 Ariz. at 579
    19, 364 P.3d at 1138
    (finding good faith exception applied, pre-McNeely, when
    officer reasonably relied “on the evanescent nature of alcohol in [the DUI
    suspect’s] blood in requesting [in 2012] the blood sample with no warrant”);
    see also State v. Edwards, 
    853 N.W.2d 246
    , 254 ¶ 19 (S.D. 2014) (finding good
    faith exception applied to officer’s warrantless, pre-McNeely blood draw in
    2013 when state’s case law had held “that the dissipation of alcohol in blood
    was a per se exigent circumstance sufficient by itself to justify conducting a
    blood test without a warrant”); State v. Meitler, 
    347 P.3d 670
    , 676 (Kan. App.
    2015) (applying good faith exception when officer obtained warrantless
    blood draw from a hospitalized, unconscious DUI suspect in 2012 based on
    state’s implied consent law later declared unconstitutional).
    ¶63           Through its revisionist reinterpretation of prior Arizona
    cases, the majority imposes an unrealistic and unreasonable expectation on
    police officers to divine, based on subsequent case law, that a
    presumptively valid state statute does not actually allow or mean what it
    says. But law enforcement officers are not legal technicians and should not
    be expected to anticipate or predict a future change in our case law.
    Exclusion of the BAC evidence here “does not result in appreciable
    deterrence” and thus “is unwarranted.” Arizona v. Evans, 
    514 U.S. 1
    , 11
    (1995) (internal quotation marks omitted). Under these circumstances,
    depriving the prosecution of that evidence necessarily “suppress[es] the
    truth” and risks “set[ting] the criminal loose in the community without
    punishment.”
