    REVIEW of a decision of the Court of Appeals.                  Affirmed.
    ¶1     DAVID    T.     PROSSER,   J.     This     is    a    review      of     an
    unpublished decision of the court of appeals,1 which affirmed a
    judgment convicting Patrick I. Hogan (Hogan) of possession of
    methamphetamine and child neglect.                 Hogan pled no contest to
    these       charges    after    the   Grant    County    Circuit      Court2      denied
    Hogan's motion to suppress evidence obtained during a search of
    his truck.

    ¶2      This fact-intensive case focuses on the reasonableness
    of    police     conduct      after     a    lawful       traffic    stop.         After     a
    sheriff's       deputy       stopped        the   defendant        for     a    seat    belt
    violation, the deputy observed what he believed to be indicia of
    the defendant's drug use.                   With this in mind, he called for
    backup.     He then wrote out seat belt citations for the defendant
    and the defendant's wife, who was not wearing her seat belt
    properly.       Before the deputy had finished the citations, a local
    officer who knew of the defendant arrived on the scene.
    ¶3      The officer reported that his department had received
    tips that the defendant had "961 issues" and was a "shake and
    bake" methamphetamine cooker.
    ¶4      With    his    suspicions          about    the     defendant       somewhat
    confirmed, the deputy asked the defendant to perform a series of
    field sobriety tests.            When the defendant passed all tests, he
    was told he was free to leave.                    At this point about 24 minutes
    had elapsed from the time the deputy initiated the traffic stop.
    ¶5      Approximately       16       seconds       later,     the       deputy    re-
    approached the defendant and asked several questions, including
    whether the defendant would consent to a search of his truck.
    The defendant consented and the officers found methamphetamine,
    equipment        and      supplies          commonly        used     to         manufacture
    methamphetamine, and two loaded handguns.                        One gun was close to
    the   defendant's        two-year-old         daughter,      who    was    sitting      in   a
    child's car seat behind her mother in the back of the truck.
    ¶6      The     defendant      sought       to     suppress       this     evidence.
    Suppression hinges on the answer to three questions.                            First, did
    2
    No.         2013AP430-CR
    the deputy have reasonable suspicion to extend a lawful traffic
    stop about seat belts to investigate whether the defendant was
    under the influence of drugs in the operation of his vehicle by
    having the defendant perform field sobriety tests?                                          Second, if
    the traffic stop was not lawfully extended to investigate drug
    use by the defendant, was the defendant's subsequent consent to
    search       his    truck       tainted         by    prior       illegality,         so     that      the
    evidence      seized          was   inadmissible?                Third,    was        the    defendant
    constructively           seized        without         reasonable         suspicion          when      the
    deputy re-approached the defendant's vehicle to request consent
    to search?
    ¶7      The defendant argues that the deputy lacked reasonable
    suspicion         to    ask     that      the    defendant          perform       field       sobriety
    tests.        He contends that there were innocent explanations for
    the observations that the deputy made, and that the deputy was
    acting       on     nothing         more     than          a    hunch     and    unsubstantiated
    information            from     a    fellow          law       enforcement       officer.              The
    defendant further argues that the taint of an illegal extension
    affected the deputy's request for consent to search, rendering
    the    consent         invalid      and    all       evidence      obtained       in        the    search
    inadmissible.                 Finally,     the        defendant         argues        that        he   was
    constructively           seized        without         reasonable         suspicion          when      the
    deputy re-approached his vehicle to ask for consent to search.
    ¶8      The State counters that possible innocent explanations
    do not render the deputy's observations meaningless in analyzing
    the basis for reasonable suspicion.                             The State also argues that,
    even    if    the      extension       was      illegal,         the    stop     ended       when      the
    3
    No.        2013AP430-CR
    deputy told the defendant he was free to leave.                                            The State
    argues the defendant was not seized within the meaning of the
    Fourth Amendment when the deputy asked him for consent to search
    his    truck,    and     the       defendant's          consent      was        therefore      valid.
    Alternatively, the State contends that any illegality was so
    attenuated from the defendant's consent that the taint of the
    illegality      had      dissipated          by       the     time        the    defendant         gave
    consent.
    ¶9    Although        the     question          of     whether          the    deputy       had
    reasonable suspicion to extend the traffic stop to administer
    field    sobriety        tests      is   a     close         one,    we    conclude         that    the
    extension       was      unlawful        based          on     the    evidence             presented.
    However,      the     defendant's            subsequent         consent          to    search       his
    vehicle came after the traffic stop had ended and the defendant
    was told he was free to leave.                              Because the police did not
    exploit the unlawful extension of the stop in order to gain
    Hogan's consent to search his vehicle, attenuation analysis is
    unnecessary         in      this     case.              Furthermore,            Hogan       was     not
    constructively seized when he gave consent to search his truck.
    We therefore conclude that the defendant's consent was valid and
    that    it    was     not    error       for      the    circuit          court       to    deny    the
    defendant's motion to suppress the evidence recovered from his
    truck.
    ¶10   Accordingly, we affirm the decision of the court of
    appeals.
    I. FACTUAL AND PROCEDURAL BACKGROUND
    4
    No.        2013AP430-CR
    ¶11    On    May    12,    2012,    Deputy     Andrew     Smith     of   the    Grant
    County Sheriff's Department was driving his squad car north on
    Wisconsin Avenue in the City of Boscobel.                          It was about 6:10
    p.m.     Deputy Smith stopped at the corner of Wisconsin Avenue and
    Oak Street.          He saw a Chevrolet truck pass in front of him
    traveling east.            The driver, Patrick Hogan, was not wearing a
    seat     belt.       Deputy       Smith     turned      right      and     activated     his
    emergency lights.           The truck promptly pulled to a stop in front
    of the Blaine Theatre.
    ¶12    When Deputy Smith approached the truck, he saw Hogan's
    wife in the front passenger seat.                    She was wearing her seat belt
    improperly with the shoulder strap underneath her arm.                             He also
    saw the couple's two-year-old child seated directly behind Mrs.
    Hogan in a child safety seat.
    ¶13    As soon as Deputy Smith began speaking with Hogan, he
    noticed      that    Hogan       was   "very       nervous,"     "real     nervous,"     and
    "shaking real bad" with upper body tremors.                              He also noticed
    that Hogan's "pupils were restricted," which he believed was "an
    indicator of drug use."                Deputy Smith acknowledged later that he
    was    not   a     drug    recognition      "expert"       but    said     he   based    his
    observations on his 12-1/2 years experience as a deputy and his
    frequent review of a "pupilometer," which he described as "a
    little    card      that    has    different        size   black    marks"      which    are
    "measured in millimeters."                 The card was provided to him in
    connection with his field sobriety training.
    ¶14    Deputy Smith collected the licenses of both Mr. and
    Mrs. Hogan and returned to his squad.                      He immediately requested
    5
    No.        2013AP430-CR
    backup from Boscobel police and stressed his observations about
    Hogan's extreme nervousness and constricted pupils.
    ¶15    Shortly thereafter, the audio portion of the squad car
    video       reflects       a    repeated      announcement,        "Warning,        potential
    hit."         The record does not explain whether this announcement
    pertained          to   Hogan,      who     was   on     probation     for    second-degree
    reckless injury and had a number of other criminal convictions.
    ¶16    Before Deputy Smith completed the citations, he was
    joined by Boscobel Police Officer Travis Dregne.                              Upon learning
    of Hogan's identity, Officer Dregne immediately remarked that
    Hogan had "961 issues," referring to the Wisconsin statutory
    chapter       on    controlled         substances.           Officer   Dregne      also    told
    Deputy Smith that "he received tips that Mr. Hogan's a shake and
    bake methamphetamine cooker."3                        Deputy Smith then requested a
    police K9 unit via radio.
    ¶17    Upon learning that the K9 unit was unavailable, Deputy
    Smith       determined         that    he    would     ask    Hogan    to     perform     field
    sobriety tests.            Approximately three minutes later, he completed
    the citations and printed them out.                       A total of approximately 13
    minutes had passed since Deputy Smith initiated the stop.
    ¶18    Deputy Smith then approached Hogan and asked him to
    step out of the truck.                  He explained to Hogan that he had made
    observations            that   he     thought     were    consistent        with   drug   use.
    3
    "Shake and bake" or "one pot" methamphetamine production
    is a manufacturing process used to produce small amounts of
    methamphetamine, often for personal use. See Raphael S. Nemes,
    Note, Shake and Bake: The Meth Threat and the Need to Rethink 
    21 U.S.C. § 841
    (C)(2), 
    88 Wash. U. L. Rev. 993
    , 999 (2011).
    6
    No.      2013AP430-CR
    Hogan's    quick    response     was    "I     don't    use     drugs."        He   then
    suggested    that    Deputy     Smith's       observations       might    be    due    to
    Hogan's     use    of    Adderall,      for     which     he     said     he    had     a
    prescription.       Deputy Smith replied that Adderall does not cause
    the symptoms he was observing, and he asked Hogan if he would
    perform a series of field sobriety tests.                 Hogan complied.
    ¶19    Deputy      Smith   had     Hogan     perform        four     tests:      the
    horizontal gaze nystagmus test, the walk and turn, the one leg
    stand, and the alphabet test.                 These tests took approximately
    eight minutes.       Deputy Smith determined that Hogan did not show
    any signs of impairment and informed Hogan he was free to leave.
    ¶20    Hogan got back into his vehicle and closed the door
    but did not start the truck and leave, even though his house was
    across the street.         Deputy Smith returned to his squad car and
    spoke with Officer Dregne.             They discussed asking for a consent
    search.     Approximately 16 seconds after Deputy Smith told Hogan
    he could leave, he returned to Hogan's stationary vehicle and
    said, "Hey, sir, can I talk to you again?"
    ¶21    Hogan got out of his truck.                Deputy Smith asked Hogan
    if there were any weapons or drugs in the truck.                        Hogan replied
    that there were not.          Deputy Smith then asked Hogan if he could
    search the vehicle.         Hogan assented to Deputy Smith's request,
    motioning for Deputy Smith to take a look.                      Deputy Smith asked
    for verbal confirmation of Hogan's consent and Hogan replied
    "Why not.    Yeah.      Go ahead."
    ¶22    Deputy      Smith   and     Officer        Dregne    searched      Hogan's
    truck.     Hogan's wife disclosed to Officer Dregne that she had a
    7
    No.         2013AP430-CR
    handgun in her purse, but did not have a concealed carry permit.
    In addition to that gun——a .380 caliber Taurus semi-automatic
    pistol——they found a loaded Walther .22 caliber pistol behind
    the passenger seat near the couple's child.
    ¶23      Deputy   Smith        and     Officer    Dregne      also        recovered
    muriatic acid, two glass bottles containing clear liquids, and a
    medicine bottle bearing Hogan's name that contained a substance
    later        identified    as     methamphetamine.             The     officers         also
    recovered         paraphernalia        used    to    manufacture      methamphetamine,
    including coffee filters, syringes, rubber gloves, and a heating
    canister.          These items, including the loaded .22 pistol, were
    stored approximately one foot from the child.
    ¶24      On May 14, 2012, Hogan was charged with possession of
    methamphetamine, manufacturing methamphetamine, possession of a
    firearm by a felon, and child neglect.4
    ¶25      On June 12, 2012, Hogan filed a motion to suppress
    evidence from the search.               He argued that any evidence recovered
    after        Deputy   Smith     told     him    he    could   leave        was    illegally
    obtained because Deputy Smith seized Hogan for a second time
    when        he   re-approached    Hogan's       vehicle   even     though        he   lacked
    reasonable suspicion to do so.                     On the same day, Hogan filed a
    4
    Contrary to 
    Wis. Stat. §§ 961.41
    (3g)(g), 961.41(1)(e1),
    941.29(2)(a), and 948.21(1)(a).  All subsequent references to
    the Wisconsin Statutes are to the 2011-12 version unless
    otherwise indicated.
    8
    No.         2013AP430-CR
    motion to dismiss, arguing that the State failed to preserve
    evidence material to his guilt or innocence.5
    ¶26     On     June    21,     2012,      Hogan      filed       another       motion    to
    suppress, this time arguing that the traffic stop was illegally
    extended       when    Deputy        Smith    required          Hogan    to     perform      field
    sobriety tests.          Hogan based this contention on the premise that
    Deputy Smith lacked reasonable suspicion that Hogan was under
    the influence of drugs.
    ¶27     That     same     day,      the       circuit      court       denied     Hogan's
    original motion to suppress the evidence from his truck.                                        The
    court reasoned that Hogan had freely consented to a search of
    his vehicle and therefore it was not an unlawful extension of
    the    stop.          However,       the     court      expressed       uncertainty          about
    whether the field sobriety tests were a lawful extension of the
    original stop, and requested informal briefing on the matter.
    ¶28     The circuit court denied Hogan's second motion on July
    10,    2012.        Although        the    court      determined        that     Deputy      Smith
    illegally       extended       the     stop      when      he   administered          the    field
    sobriety     tests,      it    concluded         that      Hogan's      subsequent       consent
    sufficiently tempered the illegality of the extension and that
    suppression was not necessary.
    ¶29     On July 27, 2012, Hogan pled no contest to possession
    of    methamphetamine          and    child      neglect.         As    part     of    the     plea
    agreement,      the     State       dismissed        the    charges      for    manufacturing
    5
    This issue has not been argued before this court, and we

    methamphetamine, possession of a firearm by a felon, and the
    seat belt citation.          The court found Hogan guilty and entered a
    judgment of conviction on September 27.
    ¶30   On October 12, 2012, Hogan gave notice of his intent
    to     seek   postconviction      relief     from   the    orders    denying     his
    motions to dismiss and suppress.             On May 15, 2014, the court of
    appeals affirmed the conviction and the circuit court's denial
    of the motions.           State v. Hogan, No. 2013AP430-CR, unpublished
    slip op. (Wis. Ct. App. May 15, 2014).                 The court reasoned that
    Hogan was not constructively seized when Deputy Smith conducted
    a search of his vehicle.          Id., ¶12.     The court also affirmed the
    circuit court's ruling that Hogan's consent "was sufficiently
    attenuated from the taint of the illegal detention."                  Id., ¶19.
    ¶31   On June 16, 2014, Hogan filed a petition for review
    with this court, which we granted on November 13, 2014.
    II. STANDARD OF REVIEW
    ¶32   Whether a defendant's constitutional rights, including
    his rights under the Fourth Amendment, have been violated is a
    question      of    constitutional     fact.          Resolving     questions    of
    constitutional fact is a two-step process.                   State v. Martwick,
    
    2000 WI 5
    ,   ¶17,   
    231 Wis. 2d 801
    ,    
    604 N.W.2d 552
    .      We     first
    uphold the circuit court's findings of historical fact unless
    they are clearly erroneous.            Id., ¶18.          We then independently
    apply constitutional principles to those facts.                Id.
    III. DISCUSSION
    ¶33   This case requires us to analyze different segments of
    an extended traffic stop.           The evidence that the defendant seeks
    10
    No.          2013AP430-CR
    to suppress was not acquired until a third distinct period of
    the stop about 28 minutes after its initiation.
    A. Extension of the Stop
    ¶34   The Fourth Amendment to the U.S. Constitution protects
    individuals        from        unreasonable       searches      and     seizures.             U.S.
    Const. amend. IV.               "There is no question that a police officer
    may stop a vehicle when he or she reasonably believes the driver
    is     violating      a       traffic     law . . . ."          State    v.         Betow,

    States v. Johnson,

    , 357 (8th Cir. 1995)).                                  However,
    "a traffic stop 'can become unlawful if it is prolonged beyond
    the    time   reasonably          required     to     complete        th[e]     mission'       of
    issuing a . . . ticket."                  Rodriguez v. United States, 575 U.S.

    , 407 (2005)).
    ¶35   After       a    justifiable     stop      is    made,    the     officer       may
    expand the scope of the inquiry only to investigate "additional
    suspicious     factors          [that]     come    to    the    officer's           attention."

    in the scope of the inquiry, when accompanied by an extension of

    must     be   supported          by     reasonable      suspicion.            See     State     v.

    11
    No.          2013AP430-CR
    regard, the legal extension of a traffic stop is essentially a
    Terry investigatory stop.                    State v. Arias, 
    2008 WI 84
    , ¶35, 
    311 Wis. 2d 358
    , 
    752 N.W.2d 748
    .
    ¶36    "The        focus        of      an     investigatory              stop      is     on
    reasonableness, and the determination of reasonableness depends
    on the totality of circumstances . . . ."                          State v. Richardson,
    
    156 Wis. 2d 128
    , 139, 
    456 N.W.2d 830
     (1990).                            Although officers
    sometimes will be confronted with behavior that has a possible
    innocent explanation, a combination of behaviors——all of which
    may provide the possibility of innocent explanation——can give
    rise to reasonable suspicion.                    See United States v. Arvizu, 
    534 U.S. 266
    , 274-75 (2002).
    ¶37    It follows that the legality of the extension of the
    traffic       stop    in    this    case      turns     on   the   presence          of     factors
    which, in the aggregate, amount to reasonable suspicion that
    Hogan    committed         a    crime     the    investigation         of    which        would    be
    furthered       by    the       defendant's          performance       of    field         sobriety
    tests.        See State v. Post, 
    2007 WI 60
    , ¶10, 
    301 Wis. 2d 1
    , 
    733 N.W.2d 634
    .
    ¶38    In    his       incident      report,    Deputy     Smith          explained       the
    basis for extending the stop: "Based upon Patrick shaking and
    his pupils being restricted, I asked him if he would be willing
    to attempt some field sobriety tests and he indicated he would."
    ¶39    Hogan's          post-arraignment             motions        challenged            the
    sufficiency of this explanation as well as the sufficiency of
    the deputy's observations at the preliminary hearing——"he was
    very     nervous,      shaking,         and     his     pupils     were      restricted"——as
    12
    No.         2013AP430-CR
    providing reasonable suspicion to extend the stop to perform
    field sobriety tests.
    ¶40     At        the     subsequent        motion      hearing,       Deputy     Smith
    testified at greater length and the State's evidence included
    video of the entire incident taken from the deputy's squad car
    and     audio        of    the       deputy's     statements      and    discussions         with
    others.       At the conclusion of the hearing, Judge Day asked for
    letter briefs.
    ¶41     In his brief, the assistant district attorney did not
    emphasize reasonable suspicion for the field sobriety tests as
    much as he emphasized Hogan's consent to search, and he did not
    rely on information the Boscobel police officer gave to Deputy
    Smith    about        Hogan       as    an    important      element    of   the     reasonable
    suspicion for the tests.                     Hogan's attorney said a bit more about
    Officer       Dregne's           statements       but   he     pointedly       observed      that
    "Officer Dregne . . . had heard (from some unknown source) that
    the defendant had a drug history."                      (Emphasis added.)
    ¶42     Judge Day concluded that the field sobriety tests were
    "an unlawful extension of the stop."                         He attributed no "power or
    persuasive       force          to     Deputy     Smith's     observation       of    [Hogan's]
    pupils," saying it "doesn't mean anything on this record."                                     He
    did not refer to the deputy's acquired information about Hogan's
    alleged       "961          issues"          or   his     alleged       involvement          with
    methamphetamine.
    ¶43     Upon careful examination of the record, we believe the
    State    could        have       made     a    valid    case    that    Deputy       Smith    had
    reasonable suspicion to pursue field sobriety tests with Patrick
    13
    No.      2013AP430-CR
    Hogan.     However, the case the State could have made in circuit
    court was not made, and, consequently, Judge Day's ruling on
    this point was not error.
    ¶44     We    review       the       totality    of    the     circumstances          to
    illustrate the problems.
    ¶45     There was no evidence and no suspicion that Hogan was
    driving    under     the   influence         of    alcohol.       There      also    was    no
    evidence that Hogan's driving had been impaired by drugs.                                  The
    deputy's observations suggested that Hogan might have been using
    drugs and thus might have violated 
    Wis. Stat. § 346.63
    (1)(am),
    which makes it illegal for a person to drive or operate a motor
    vehicle with "a detectable amount of a restricted controlled
    substance    in    his     or    her      blood."      As     a   result,      the     issue
    presented to the circuit court was whether there was reasonable
    suspicion     that    Hogan       had      been     using     controlled       substances
    recently enough that evidence of that use would be detected in
    his blood.
    ¶46     Any   order    for       a    blood    test    would   require         probable
    cause.     State v. Tullberg, 
    2014 WI 134
    , ¶31, 
    359 Wis. 2d 421
    ,
    
    857 N.W.2d 120
    .          Field sobriety tests were intended to secure
    evidence to establish probable cause.
    ¶47     Deputy Smith was an experienced officer with 12-1/2
    years of service in the Grant County Sheriff's Department.                                 His
    experience    should       have       been   a     plus.      State     v.    Meyer,       
    216 Wis. 2d 729
    , 752-53, 
    576 N.W.2d 260
     (1998).                       His instincts were,
    in fact, correct.           However, Deputy Smith conceded that he was
    not a drug recognition expert and his testimony about restricted
    14
    No.     2013AP430-CR
    pupils    undermined    his   credibility   in   the   court's   eyes.    The
    court heard the following testimony on cross-examination:
    Q:   You also indicated that you observed his pupils
    to be restricted, right?
    A:     Yes, sir.
    Q:     Okay.     Was it sunny out that day?
    A:     Yes, sir.
    Q:     And pupils restrict when it's sunny?
    A:     Yes, sir.
    Q:     You're not a drug recognition expert, right?
    A:     Correct.
    Q:     What drugs cause pupil restrictions?
    A:   Cocaine being one.   I'm sure there's others, but
    I'm not a drug recognition expert.
    Q:     Do you know what methamphetamine does to pupils?
    A:     No, sir.
    Q:   Okay. Approximately what size do you believe Mr.
    Hogan's pupils were?
    A:     Three millimeters.
    . . . .
    Q:   [D]o you know what the normal pupil size is for
    an adult male?
    A:     Four to five millimeters, I believe.
    ¶48    For a variety of reasons, the circuit court put no
    stock in the deputy's testimony about restricted pupils as a
    factor in establishing reasonable suspicion.            The deputy did not
    have definitive information at any point on how drug use might
    15
    No.     2013AP430-CR
    affect       pupil    size.6      He   referred     to     his   familiarity     with   a
    pupilometer card but he did not bring the card to substantiate
    or supplement his testimony.
    ¶49       Consequently, the case for reasonable suspicion rests
    primarily on the deputy's observations that Hogan's upper body
    was shaking and "he appeared to be very nervous."                        These points
    appear in his suppression hearing testimony and are even more
    prominent in the audio that accompanies the video.
    ¶50       Nervousness, anxiety, and tremors are consistent with
    methamphetamine            use.         National      Highway       Traffic      Safety
    Administration, Drugs and Human Performance Fact Sheets, Report
    No. DOT HS 809 725, at 63 (April 2014).                      These characteristics,
    however, may also have innocent explanations.                        The possibility
    that innocent explanations may exist for observed behavior does
    not     preclude      a    finding     of   reasonable       suspicion,    but    as    a
    practical matter, police cannot expect to conduct field sobriety
    tests on every motorist who is shaking and nervous when stopped
    by an officer.
    ¶51       Officer Dregne's comments that Hogan had "961 issues"
    and that Officer Dregne had "received tips that Mr. Hogan's a
    shake       and    bake   methamphetamine        cooker"    undoubtedly    influenced
    6
    In fact, during the course of the discussion about pupil
    size, Deputy Smith suggested that restricted pupils are
    consistent with cocaine use.     However, according to a source
    cited by the State, cocaine use may lead to dilated pupils, not
    restricted pupils.      See National Highway Traffic Safety
    Administration, Drugs and Human Performance Fact Sheets, Report
    No. DOT HS 809 725, at 21 (April 2014).

    Deputy Smith's decision to proceed as he did.                      At least some of
    Deputy         Smith's    observations        meshed       with   Officer       Dregne's
    information.          Ultimately, however, when a court is asked to rule
    on a suppression motion, the court must evaluate whether the
    information conveyed by a fellow officer, and relied upon in
    taking         the    action    under     review,    was    reliable      information,
    because         the    officer       conveying    the    information      had    either
    firsthand knowledge or a reliable informant.                      No effort was made
    in this case to show that Officer Dregne's tips came from a
    reliable informant.7             Such an effort, if successful, would have
    made       a    substantial          difference     in   establishing       reasonable
    suspicion.
    ¶52      The audio from the incident several times records an
    urgent announcement, perhaps from the squad computer: "Warning,
    potential hit."               These announcements are never referred to in
    the    testimony         or    the    argument,     so   that     their   import     and
    7
    To assess the reliability of an anonymous tip, a totality
    of the circumstances test is used. Illinois v. Gates, 
    462 U.S. 213
    , 230-31 (1983). Courts must take into account the quantity
    and quality of information received during this analysis.
    Alabama v. White, 
    496 U.S. 325
    , 330 (1990).     The quantity and
    quality are inversely proportionate: if one is relatively low,
    the other must be relatively high for the tip to be deemed
    reliable. 
    Id.
     Courts consider such factors as awareness of the
    informant's identity, an officer's past interactions with the
    informant, and predictive information offered in the tip.    See
    United States v. Am, 
    564 F.3d 25
     (1st Cir. 2009); United States
    v. Crozier,

    may have been completely reliable, but any such facts are not in
    evidence.

    relationship to Hogan, if any, are unknown.                             If either Deputy
    Smith    or     Officer   Dregne      had     been    shown       to    know     of   Hogan's
    criminal record, which included three felony convictions and a
    drug conviction as well as his probationary status, the case for
    reasonable       suspicion     would        have     been     greatly         strengthened.
    After all, Hogan's statement to Deputy Smith that "I don't do
    drugs"        could   have    been     challenged,          and        Hogan's    immediate
    explanation that Deputy Smith's observations could be attributed
    to Hogan's use of prescription Adderall could have been viewed
    even    more     skeptically       because    of     background         information       from
    reliable sources.
    ¶53    Reasonable suspicion here is a close question.                              But
    the State's failure to tie up loose ends in circuit court should
    not be rewarded just because the case is close.                           As a result, we
    will     not    disturb      the    circuit        court's    conclusion          that    the
    extension of the stop for field sobriety tests was not lawful.
    B. Consent to Search
    ¶54    Our determination that the extension of the traffic
    stop was not lawful, based on the record before us, does not
    resolve this case.           The somewhat unusual feature of the case is
    that the evidence Hogan seeks to suppress was not obtained as a
    result of the field sobriety tests but rather as a result of the
    consensual search of Hogan's vehicle.
    ¶55    "Warrantless        searches    are    per    se    unreasonable          under
    the Fourth Amendment."              State v. Williams, 
    2002 WI 94
    , ¶18, 
    255 Wis. 2d 1
     (2002).         However, one of the "specifically established
    and well-delineated" exceptions to the warrant requirement is
    18
    No.         2013AP430-CR
    consent; if an individual freely gives consent for police to
    search    his    or    her   vehicle,    the        police    may    do     so    without    a
    warrant.

    ¶56   Hogan does not dispute that he gave his consent for
    Deputy Smith to search his truck.                       Instead, Hogan argues that
    his illegal detention immediately prior to his consent tainted
    the   consent     and   Deputy      Smith     was       therefore    not     excused     from
    obtaining a warrant to search Hogan's vehicle.
    ¶57   Consent analysis proceeds under a distinct framework
    if consent was given following some illegal action by police.
    Consent, even when voluntary, is not valid when obtained through
    exploitation of an illegal action by police.                        State v. Phillips,
    
    218 Wis. 2d 180
    ,         204       (1998).               Stated          differently,
    "[w]hen . . . consent          to    search        is     obtained        after    a   Fourth
    Amendment violation, evidence seized as a result of that search
    must be suppressed as 'fruit of the poisonous tree' unless the
    State can show a sufficient break in the causal chain between
    the illegality and the seizure of evidence."                        
    Id.
    ¶58   Attenuation         analysis           examines     three         factors       to
    determine       whether      consent     is        sufficiently       attenuated         from
    illegal action to be removed from the taint of illegality: "(1)
    the temporal proximity of the official misconduct and seizure of
    evidence; (2) the presence of intervening circumstances; and (3)
    the   purpose         and    flagrancy        of     the     official         misconduct."
    Phillips, 
    218 Wis. 2d at
    206 (citing Brown v. Illinois, 
    422 U.S. 590
    , 603-04 (1975)).          The application of these factors will vary
    on a case-by-case basis.             Our focus here is determining whether
    19
    No.      2013AP430-CR
    these factors sufficiently safeguard constitutional protections
    when the illegal action is the unlawful extension of a traffic
    stop.
    ¶59    Hogan suggests that the third factor is inappropriate
    in    this     analysis    because        the    "subjective          intent        of . . . law
    enforcement officers is irrelevant to whether . . . officers are
    unfairly       benefitting         from     the        violation         of . . . suspects'
    rights."          Hogan     further        contends         that        the     focus     in    the
    attenuation       analysis       should         be    on    why    the        individual       gave
    consent.        He offers a hybrid test that combines the first two
    factors from Phillips with a constructive seizure analysis like
    that in Williams.
    ¶60    Considering the closeness of this case with regard to
    reasonable suspicion, it is no surprise that Hogan downplays the
    importance of the third factor, i.e., the purpose and flagrancy
    of the official misconduct.                     While flagrant violations of the
    law     by     police     should     weigh           against      the     validity        of    any
    subsequent consent, see United States v. Edmons, 
    432 F.2d 577
    (2d     Cir.    1970),     the     mere     failure         to     establish           reasonable
    suspicion because the State did not submit all the evidence that
    it had available is a different matter.
    ¶61    Hogan's desired focus on why a person gives consent
    implicates questions of voluntariness.                            Involuntary consent is
    invalid,       regardless     of     any        prior      illegality          or   attenuation
    therefrom.         See    State     v.     Vorburger,          
    2002 WI 105
    ,    ¶89,    
    255 Wis. 2d 537
    , 
    648 N.W.2d 829
     (citing Schneckloth v. Bustamonte,
    
    412 U.S. 218
     (1973)).             Attenuation analysis is not voluntariness
    20
    No.         2013AP430-CR
    analysis, and it is not meant to cure the involuntary waiver of
    rights.       Rather, attenuation analysis examines whether voluntary
    consent       is     tainted          by    prior          illegality.              Phillips,        
    218 Wis. 2d at 204-05
    .
    ¶62    Viewed in this light, we conclude that the attenuation
    test    laid       out    in    Phillips       is       the    proper       test     to    apply     for
    analyzing       voluntary            consent       to      search      a    vehicle        when    that
    consent comes after the illegal extension of a traffic stop.
    The    three       Phillips         factors    adequately           protect        the     rights     of
    motorists in such situations.                              In many ways, the concept of
    constructive seizure——which Hogan argues should be included in
    the    analysis——is            already      built       into     the       Phillips       attenuation
    test.
    ¶63    We    have           held    that       a    traffic         stop     ends     when     a
    reasonable         person,          under   the        totality     of      the      circumstances,
    would feel free to leave.                    Williams, 
    255 Wis. 2d 1
    , ¶35.                        Given
    the wide range of possible "circumstances" in a traffic stop, it
    is    not     possible         to    expound       a    bright-line          rule     of    when     the
    reasonable driver would feel free to leave.                                  However, it is not
    uncommon for officers to tell drivers they are "free to leave,"
    may be "on their way," or to "have a nice day" at the conclusion
    of a traffic stop.
    ¶64    The end of a traffic stop is important to two of the
    factors in the attenuation analysis.                             First, the circumstances
    giving rise to the end of a traffic stop will often (though
    perhaps       not        always)       include          the     passage       of      time,       which
    implicates         the     first       attenuation            factor.        Second,        and    more
    21
    No.      2013AP430-CR
    important,        the    end     of     a    traffic         stop     is     a     significant
    intervening event for purposes of attenuation analysis.
    ¶65     Thus,      Hogan's       proposed          hybrid      attenuation          test    is
    unnecessary because it would focus on improper factors while
    placing redundant value on other factors.                           We see no reason to
    replace the Phillips attenuation analysis in this context.
    ¶66     It is important to note that attenuation analysis may
    not be necessary in all cases.                    "[A]ttenuation analysis is only
    appropriate where, as a threshold matter, courts determine that
    'the challenged evidence is in some sense the product of illegal
    governmental activity.'"               New York v. Harris, 
    495 U.S. 14
    , 19
    (1990) (citation omitted).                  If the unlawful police conduct was
    not a "but-for" cause of the search, attenuation analysis is
    unnecessary because the consent is not tainted by the unlawful
    conduct in such a case.               See Hudson v. Michigan, 
    547 U.S. 586
    ,
    592 (2006).
    ¶67     After a traffic stop has ended, police may interact
    with the driver as they would with any citizen on the street.
    See Williams, 
    255 Wis. 2d 1
    , ¶35.                       That is, if a person is not
    seized,    police       may    request        consent        to     search        even    absent
    reasonable suspicion.            See Florida v. Bostick, 
    501 U.S. 429
    , 431
    (1991).      In    a    sense,    the       end    of    a   traffic       stop    places       the
    officer and driver back on equal footing, with the driver free
    to leave if he wishes (because if the driver were not free to
    leave, the traffic stop would not in fact have ended).
    ¶68     Given the myriad possible scenarios in which police
    and the public may interact on the side of the road, we cannot
    22
    No.     2013AP430-CR
    postulate that the end of a traffic stop will always render
    attenuation analysis unnecessary.               However, the end of the stop
    will be a significant factor in determining the necessity of
    attenuation analysis, at the very least.
    ¶69        In this case, we conclude that the end of the traffic
    stop       does    render   attenuation   analysis    unnecessary   because   it
    cannot be said that the extension of the stop was a but-for
    cause of Hogan's consent.            Deputy Smith told Hogan that he was
    free to leave, encouraged him to wear his seat belt, and advised
    him to get his windshield fixed.                He then returned to his squad
    car.        Deputy Smith waited approximately 16 seconds before re-
    engaging Hogan.             When we compare these facts to the facts in
    Williams,8 we have little trouble concluding that Hogan was not
    constructively seized at the time Deputy Smith requested his
    consent to search the vehicle.                 A reasonable person, under the
    totality of the circumstances, would have felt free to leave——to
    drive across the street to his home.
    8
    In Williams, a police officer stopped the defendant's
    vehicle for a traffic violation, for which the officer issued a
    warning. The defendant signed the warning, the two shook hands,
    and the officer told the defendant in a conversational tone he
    could "get on [his] way."    State v. Williams, 
    2002 WI 94
    , ¶¶9-
    12, 
    255 Wis. 2d 1
    , 
    646 N.W.2d 834
    .       After taking two steps
    toward his squad car, the officer asked for and was granted
    consent to search the vehicle, where the officer found heroin
    and a weapon. Id., ¶12-13. This court determined the officer's
    words   and  actions,   considered   as  a   whole,  communicated
    permission to leave and, therefore, the defendant was no longer
    seized after the officer stated the defendant could "get on his
    way."   Id., ¶29.   Because a reasonable person would have felt
    able to leave the scene, the officer's subsequent questioning
    did not constitute a seizure for purposes of the Fourth
    Amendment and the defendant's consent was valid. Id., ¶28.
    23
    No.         2013AP430-CR
    ¶70    It is true that the emergency lights on Deputy Smith's
    squad    car     remained       on   for   the      entire       duration      of    the    stop,
    including      the     time     in    which    Deputy        Smith      re-engaged         Hogan.
    However, that alone is not enough for us to conclude that the
    stop had not ended.                  Police often may leave their emergency
    lights on for safety reasons when they and the motorist are
    pulling       back    onto     the    roadway       after     a    traffic       stop.        The
    continuing illumination of the emergency lights was not enough
    to create an ongoing——or new——seizure of Hogan.
    ¶71    We therefore conclude that even though the extension
    of the traffic stop has been deemed illegal, the extension of
    the stop was not a but-for cause of the consent.                                    The traffic
    stop had concluded.              Hogan had returned to his truck and was
    free to leave.          He gave consent to search after Deputy Smith re-
    approached him and asked for consent.
    ¶72    Our     conclusion       that     Hogan       was     not       constructively
    seized when Deputy Smith requested consent to search Hogan's
    truck     also       resolves    Hogan's       argument          that   his     consent       was
    invalid       because     it     occurred        during      a     constructive         seizure
    initiated      without       reasonable       suspicion.           As    discussed         above,
    without a constructive seizure, police do not need reasonable
    suspicion to request consent to search.                           See Bostick, 
    501 U.S. at 431
    .
    ¶73    Because Hogan's rights were not violated, it was not
    error for the circuit court to deny his motions to suppress.
    IV. CONCLUSION
    24
    No.         2013AP430-CR
    ¶74    Although       the    question          of    whether        the      deputy      had
    reasonable suspicion to extend the traffic stop to administer
    field    sobriety         tests     is   a     close       one,    we    conclude       that     the
    extension       was       unlawful       based        on     the    evidence           presented.
    However,       the    defendant's            subsequent       consent        to      search      his
    vehicle came after the traffic stop had ended and the defendant
    was told he was free to leave.                          Because the police did not
    exploit the unlawful extension of the stop in order to gain
    Hogan's consent to search his vehicle, attenuation analysis is
    unnecessary          in     this     case.            Furthermore,          Hogan        was     not
    constructively seized when he gave consent to search his truck.
    We therefore conclude that the defendant's consent was valid and
    that    it     was    not    error       for    the     circuit         court     to    deny     the
    defendant's motion to suppress the evidence recovered from his
    truck.
    ¶75    Accordingly, we affirm the decision of the court of
    appeals.
    By    the    Court.—The      decision          of    the    court       of     appeals    is

    of limited value for determining whether a driver violated this
    statute).
    ¶77        In       the    present      case,      Deputy    Andrew       Smith      suspected
    Patrick Hogan of operating a motor vehicle with a detectable
    amount       of        a    restricted         controlled        substance       in       his    blood,
    contrary to 
    Wis. Stat. § 346.63
    (1)(am).                                 This offense does not

    ,           
    709 N.W.2d 474
    .             This    offense         has   two
    elements: (1) the defendant drove or operated a motor vehicle on
    a highway; and (2) the defendant had a detectable amount of a
    restricted controlled substance in his or her blood at the time
    the defendant drove or operated a motor vehicle.                                     See

    performance on standard field sobriety tests would support a
    determination that there is probable cause to arrest someone who
    is suspected of violating § 346.63(1)(am), operators may violate
    this statute even though they are able to pass standard field
    sobriety tests.                  Accordingly, whether a driver who violates this
    1
    No.   2013AP430-CR.akz
    statute    is   brought   to   justice       might   often   depend   on   whether
    there is probable cause to arrest the driver and take him or her
    to a hospital for further testing, regardless of how he or she
    performs on standard field sobriety tests.               In the present case,
    the circuit court's findings of fact do not allow me to engage
    in this type of analysis.

    ¶82    Contrary      to     the        majority's    assertions,          this    case
    presents     the    quintessential            example     of    when     an    attenuation
    analysis is needed.            It is undisputed that the extension of the
    traffic stop was unconstitutional.                   The deputy reengaged Hogan a
    mere 16 seconds later, seeking consent to search.
    1

    ¶83    Where consent is obtained so closely on the heels of
    acknowledged         police       misconduct,       attenuation         analysis      is     the
    means by which we determine "whether the evidence objected to
    was obtained by exploitation of a prior police illegality or
    instead by means sufficiently attenuated so as to be purged of
    the taint."          State v. Anderson, 
    165 Wis. 2d 441
    , 447-48, 
    477 N.W.2d 277
     (1991).
    ¶84    In this case an attenuation analysis reveals that the
    taint     from       the    deputy's        unconstitutional            actions      was     not
    removed.       Therefore the evidence obtained from that search must
    be suppressed.          Accordingly, I respectfully dissent.
    I
    ¶85    The    majority       spends     a    substantial         portion      of     its
    analysis attempting to re-litigate the facts of this case to
    determine       whether       the    extension        of    the     traffic         stop     was
    unconstitutional.             Majority        op.,    ¶¶38-52.            Ultimately,         it
    acquiesces, as it must, to the conclusion reached by the circuit
    court and the court of appeals——the extension of the stop was
    illegal.       Id., ¶53.
    ¶86    Acknowledging that designating the extension unlawful
    does    not    resolve      the     case,    the    majority      turns       its    focus    to
    whether       Hogan's      consent    for     the    search       was     tainted     by     the
    extension.       Id., ¶56.           It observes that consent "is not valid
    when    obtained       through      exploitation       of    an    illegal          action    by
    police."         Id.,      ¶57.      It     then    explains      that        "[a]ttenuation
    analysis examines three factors to determine whether consent is
    sufficiently attenuated from illegal action to be removed from
    2
    No.   2013AP430-CR.awb
    the taint of illegality."                    Id., ¶58.          This statement is followed
    by a lengthy discussion of those three factors.                                  Id., ¶¶58-65.
    ¶87    Abruptly shifting paths, the majority fails to apply
    the three factors.               Instead, it considers whether a person in
    Hogan's     position           would     have     felt          free     to     leave      after     the
    unlawful     extension           of     the     traffic          stop.          Id.,       ¶63.       It
    determines     that        a    reasonable       person          would        have   felt    free     to
    leave due to the deputy's statement: "you're free to go."                                           See
    id., ¶69.      Based on this rationale, the majority sets aside the
    preceding illegality in the traffic stop and determines that an
    attenuation analysis is unnecessary.                             It states: "[b]ecause the
    police did not exploit the unlawful extension of the stop in
    order to gain Hogan's consent to search his vehicle, attenuation
    analysis    is    unnecessary            in     this       case."         Id.,       ¶9.      Without
    conducting       an    attenuation            analysis,           the     majority         ultimately
    concludes that Hogan's consent to the search was valid.                                             Id.,
    ¶¶69, 71.
    II
    ¶88    In asserting a reasonable person would have felt free
    to leave after the unlawful extension of the traffic stop, the
    majority constructs a fiction.
    ¶89    Hogan         had    been        pulled       over        for     not     wearing      his
    seatbelt.         After          the     deputy        checked          Hogan's        license       and
    registration,         he       asked     Hogan       to        step     out     of   his     vehicle.
    Despite Hogan's clear agitation and expressed desire to go home,
    the   deputy      prolonged            the    stop        to     such     an     extent      that     it
    constituted an unconstitutional extension of the stop when he
    3
    No.    2013AP430-CR.awb
    asked Hogan to perform multiple sobriety tests.                         After the tests
    were completed, the Deputy told Hogan he was free to leave.
    ¶90    However, sixteen seconds after Hogan got back into his
    vehicle, with the lights on the patrol car still flashing, the
    deputy walked back to the defendant and reengaged.                            After asking
    for and receiving Hogan's consent to search, the deputy found
    methamphetamine,           drug   paraphernalia,         and    two     loaded     guns    in
    Hogan's vehicle.
    ¶91    Like     United     States   Supreme       Court     Justice       Souter,    I
    have   a     hard    time   imagining      that    an    average      individual       would
    believe that he has nothing to lose if he refuses to cooperate
    with the police or that he had any free choice to ignore the
    police altogether.           United States v. Drayton, 
    536 U.S. 194
    , 212
    (2002) (Souter, J., dissenting) ("It is very hard to imagine
    that either [defendant] would have believed that he stood to
    lose nothing if he refused to cooperate with the police, or that
    he   had     any    free    choice   to    ignore   the        police       altogether.    No
    reasonable          passenger     could     have        believed        that,     only     an
    uncomprehending one.").
    ¶92    The reasonable person "free to leave" standard bears
    little relationship to what individuals actually believe:
    Courts and scholars have repeatedly noted that the
    free-to-leave test is a highly unrealistic judicial
    construct that stretches credulity to its limits in
    assuming that any reasonable person (young or old;
    guilty or innocent) would literally feel free to leave
    and ignore a police officer's questions without
    consequence.

    That defendants often consent to searches of areas that reveal
    incriminating           evidence     demonstrates          that       people    often        do   not
    feel     free      to    decline     an        officer's       request,        even    absent      a

    ¶93     "[E]mpirical studies over the last several decades on

    influence,         and    politeness           have     all    converged        on     a     single
    conclusion: the extent to which people feel free to refuse to
    comply        is    extremely        limited          under       situationally             induced
    pressures."         Janice Nadler, No Need to Shout: Bus Sweeps and the

    Professor LaFave has observed "only the most thick-skinned of
    suspects" would feel free to leave in some of the circumstances

    ¶94     In the present case, the very nature of the stop was
    coercive.          The deputy necessarily displayed his power and the
    accoutrements of his authority in order to get Hogan to pull
    over his vehicle.            Once there, the deputy used his authority to
    require Hogan's compliance with unconstitutional sobriety tests,
    while    another         officer     looked       on.         There    was     no     real    break
    between this series of events and the deputy's request to search
    5
    No.    2013AP430-CR.awb
    Hogan's vehicle.          Although the deputy told Hogan he was free to
    leave, within a mere 16 seconds, he reengaged seeking consent to
    search Hogan's vehicle.
    III
    ¶95    The       majority's      suggestion            that    Hogan's     consent     to
    search     his    vehicle    was       unrelated        to    the     illegality      is   also
    unpersuasive.           Would a reasonable person in Hogan's situation,
    who is on probation and aware that there was methamphetamine,
    drug paraphernalia, and two loaded guns in his vehicle, blithely
    consent     to    a    search     of   his    vehicle         absent     the    presence     of
    coercion?         The answer is no.                The illegal extension of the
    traffic stop unquestionably played a role in Hogan's consent.
    ¶96    An       application      of    attenuation            analysis    demonstrates
    that the consent was not so attenuated from the illegality to
    render it free of the taint from the unconstitutional extension
    of the traffic stop.
    ¶97        Attenuation       analysis        is        well-established         in   our
    jurisprudence.          Originating in the United States Supreme Court,
    it   was    developed       to    help      courts      determine       whether       evidence
    obtained following illegal police activity must be excluded as
    the fruit of the poisonous tree.                   Wong Sun v. United States, 
    371 U.S. 471
    , 488 (1963).             The Court set forth the relevant inquiry
    as   follows:         "whether,    granting        establishment          of    the    primary
    illegality, the evidence to which instant objection is made has
    been come at by exploitation of that illegality or instead by
    means sufficiently distinguishable to be purged of the primary
    taint."

    ¶98 In Brown v. Illinois, 
    422 U.S. 590
    , 603-04 (1975), the
    Supreme Court declined to adopt a "but for" approach based on a
    causal      connection,        and   announced       instead        three    factors     that
    courts       should      consider        in     determining          if     evidence      was
    sufficiently attenuated from the initial illegality to purge it
    of    the    primary      taint:     temporal       proximity,        the     presence     of
    intervening circumstances, and the flagrancy of the misconduct.
    ¶99    I address each factor in turn:
    ¶100 The        first    factor,        temporal      proximity,       requires      a
    consideration of "both the amount of time between the illegal
    [act] and the consensual search and the conditions that existed
    during that time."           Phillips, 
    218 Wis. 2d at 206
    .
    ¶101 Sixteen seconds elapsed between the unconstitutional
    extension of the stop and the time the deputy reengaged Hogan
    seeking consent to search.               In assessing temporal proximity, we
    have previously determined that the timespan of a few minutes
    weighs against a consensual search.                    Id.; see also United States
    v.    Macias,    
    658 F.3d 509
    ,    524    (5th    Cir.    2011)       (thirty-second
    interval between illegal extension of traffic stop and request
    for    consent        weighed    against       attenuation);         United    States      v.

    79 F.3d 973
    , 979-80 (10th Cir. 1996) (passage of less
    than a minute between return of driver's license and request to
    search not sufficient to purge the taint of an illegal stop);
    McGaughey v. State, 
    37 P.3d 130
    , 141 (Okla. Crim. App. 2001)
    (the fact that only a few minutes had passed between the illegal
    detention       and    the     request    for      consent     to    search    "weigh[ed]
    heavily against finding the taint cleansed").

    ¶102 The United Stated Supreme Court has stated that in
    some     circumstances           even    a    45-minute         timespan          would     be
    insufficient to purge the taint.                  Rawlings v. Kentucky, 
    448 U.S. 98
    , 107 (1980).        Here, we are considering a mere 16 seconds that
    passed     between    the    illegal         extension     of     the      stop    and     the
    deputy's      reengagement,         seeking       consent       to      search      Hogan's
    vehicle.           Such     an     abbreviated       timespan           weighs      against
    attenuation.
    ¶103 In     considering      temporal       proximity,        courts       take    into
    account    the     conditions      that      existed.           Admittedly,        in     some
    circumstances, the existence of a congenial atmosphere may weigh
    in favor of attenuation.                See Rawlings, 
    448 U.S. at 109
    .                      In
    this   case   it     does   not.         Although    the    atmosphere         during      the
    encounter was not overtly threatening, Hogan appeared agitated
    throughout the stop, expressing his desire to leave.                                 It was
    only the deputy's assertion of authority that kept him there.
    The extension of the stop further enhanced the unequal power
    dynamic between the deputy and Hogan.                       Far from removing the
    taint of the illegality, the conditions of the illegal extension
    of   the   stop    combined       with    the     short    time      span    between       the
    extension and the consent suggest that the consent was tainted
    by the illegality.
    ¶104 The second factor, intervening circumstances, refers
    to events occurring between the illegality and the consensual
    search.     Phillips, 
    218 Wis. 2d at 208
    .                  In this case, after the
    extension of the stop, the deputy told Hogan that he was free to
    leave and they both returned to their vehicles.                            Although these
    8
    No.    2013AP430-CR.awb
    circumstances are significant as they could be viewed as an end
    of the traffic stop, they are not sufficient to wipe clean the
    slate such that the consent was untainted by the illegality.
    ¶105 This       court    described       what     intervening      circumstances
    would support a determination of attenuation in Phillips, 
    218 Wis. 2d 180
    .        In    that    case,     after     illegally      entering     the
    defendant's        home,       officers    had     a   short    discussion       with   the
    defendant.         An    officer       informed    the    defendant       that   they   had
    received information that the defendant had drug paraphernalia
    and marijuana and explained that they did not have a warrant to
    search       his   bedroom.         
    Id. at 209
    .        "This   discussion       was
    significant [] because it provided the defendant with sufficient
    information with which he could decide whether to freely consent
    to the search."           
    Id. at 208-09
    .           We stated that the discussion
    "illustrates that the defendant was not improperly surprised,
    frightened, or confused when he consented to the search of his
    bedroom," and thus concluded that the officers did not exploit
    their unlawful entry to obtain consent to search.                         
    Id. at 209
    .
    ¶106 The circumstances in Phillips are not present in this
    case.     At no time did the deputy give any indication that Hogan
    could     decline       the     deputy's    request       to    search     his   vehicle.
    Indeed,       during     the     unlawful        extension     of   the     stop,   Hogan
    expressed his belief that if he did not accede to the deputy's
    requests, it would be used against him.                      Nothing in the deputy's
    request for consent to search the vehicle would have dispelled
    that belief.            The intervening circumstances do not remove the
    taint from the unlawful extension of the stop.

    ¶107        The    third        factor   to     consider     is    "the     purpose      and

    Id.
          This       factor
    considers whether the conduct of the officers rose "to the level
    of     conscious          or     flagrant       misconduct         requiring      prophylactic
    exclusion."             Anderson,

     (quoting Rawlings, 
    448 U.S. at 110
    ).
    ¶108 The deputy's conduct indicates a conscious attempt to
    gain    consent          for     the    search.        His     exchange        with    the    other
    officer       at        the     scene    suggests       that    the      entire       purpose    of
    extending      the        stop     was    to    find    a    reason      to     search   Hogan's
    vehicle.       Seeking consent to search is generally consistent with
    exemplary work of law enforcement.                           Detaining a suspect longer
    than reasonably justified by the stop in order to obtain consent
    crosses the line.                 I acknowledge, however, that the deputy may
    not have realized that the extension of the stop was unlawful.
    Thus, it is hard to conclude that his conduct was flagrant.
    Overall, this factor appears neutral in determining attenuation.
    ¶109 Having considered the three traditional factors of an
    attenuation analysis, I conclude that on balance, they weigh
    against    a       determination          of    attenuation.          Although         the    third
    factor appears neutral, both the first and second factors weigh
    against it.              The facts of this case and the relevant case law
    reveal that there was no real break between the unconstitutional
    extension      of        the     traffic     stop      and   the    deputy's       request      for
    consent to search Hogan's vehicle.

    ¶110 Although           officers       may      conduct       brief       seizures     when
    there    is     reasonable           suspicion       of    a    traffic       violation,       "the
    tolerable        duration        of    police        inquiries        in    the    traffic-stop
    context is determined by the seizure's 'mission'—to address the
    traffic violation that warranted the stop."                             Rodriguez v. United
    States,        
    135 S. Ct. 1609
    ,    1614        (2015).          As    the     majority
    acknowledges,             an   officer       may     not       extend      the    stop      without
    additional reasonable suspicion.                           Majority op., ¶35.                Absent
    such reasonable suspicion, the prolonged detention becomes an
    unlawful seizure, intruding on the citizen's personal liberty.
    ¶111 Here,         consent      to    search       Hogan's      vehicle       was    sought
    only seconds after the illegal extension of the traffic stop.
    To conclude that consent obtained so closely on the heels of
    acknowledged police misconduct was valid would lend an air of
    legitimacy to questionable police tactics.                              This is the classic
    example of when the exclusionary rule should apply.                                      See State
    v. Scull, 
    2015 WI 22
    , ¶22, 
    361 Wis. 2d 288
    , 
    862 N.W.2d 562
    (observing that the two rationales for the exclusionary rule are
    "assurance       of       judicial      integrity         and    deterrence         of    unlawful
    police conduct").              The evidence should have been suppressed.
    ¶112     Accordingly,          for     the      reasons       set     forth      above,    I
    respectfully dissent.
    ¶113 I       am    authorized         to   state       that     Justice       SHIRLEY     S.
    ABRAHAMSON joins this dissent.
