    After police officers found a Titan .25 caliber semi-automatic handgun in his
    rental vehicle during a consensual search following a traffic stop, Alphonso Barnum
    was charged with being a felon in possession of a firearm, a violation of 18 U.S.C. §§
    922(g)(1) and 924(a)(2). Barnum moved to suppress the evidence that police seized,
    challenging the legality of the traffic stop and alleging that his consent to search his

    Western District of Missouri, sitting by designation.
    rental vehicle and his person was not voluntarily given. The district court2 denied
    Barnum’s motion. Barnum then entered a conditional guilty plea, reserving the right
    to appeal the denial of his suppression motion. Barnum now appeals, and for the
    reasons discussed below, we affirm.
    I.    BACKGROUND
    On the afternoon of July 23, 2007, Officer Jerry Hatler of the Bettendorf, Iowa
    Police Department drove through the parking lot of the Traveler Motel as part of his
    routine patrol. The Traveler Motel has a reputation among local law enforcement as
    a frequent site of illegal drug and prostitution activity. Officer Hatler cross-referenced
    the registrations of the vehicles parked in the lot against a list of outstanding warrants.
    One of these vehicles was a silver 2005 Dodge Stratus, registered to Kimberly Car
    City, an automobile repair shop in Davenport, Iowa. After checking all of the
    vehicles, Officer Hatler left the Traveler Motel parking lot and continued his normal
    patrol activities.
    A few hours later, around 6:00 p.m., Officer Hatler was driving on Brown
    Street when he saw the same silver Dodge Stratus pull out of the Traveler Motel
    parking lot onto Brown Street. Officer Hatler followed the vehicle on Brown Street
    and then on 14th Street for about twenty seconds before he noticed that the vehicle’s
    middle taillight failed to illuminate when the driver, Barnum, applied the vehicle’s
    brakes, thereby violating Iowa Code § 321.387. See 
    id. (“All lamps
    and lighting
    equipment originally manufactured on a motor vehicle shall be kept in working
    condition . . . .”). Officer Hatler then initiated a traffic stop.

    District of Iowa.
    -2-
    Officer Hatler approached the stopped vehicle, asked Barnum for his license,
    and notified him of the vehicle’s malfunctioning taillight. Barnum explained that he
    was not aware that the taillight was out because he did not own the vehicle; it was
    loaned to him by an automobile repair shop while his automobile was being repaired.
    Barnum gave Officer Hatler his license and the vehicle rental agreement, and Officer
    Hatler returned to his patrol cruiser to check the records of Barnum and his female
    passenger, Michelle Pugh. The check on Barnum revealed prior involvement with
    drugs and a conviction for possession of a firearm by a felon.
    At this time, Officer Colin Ward arrived to back up Officer Hatler. Officer
    Hatler prepared a warning ticket for the taillight infraction and returned to Barnum’s
    rental vehicle to give Barnum the warning and return his license and the rental
    agreement. Officer Hatler asked Barnum to step out of the vehicle to complete the
    warning ticket. Together they walked to the rear of the rental vehicle, where Barnum
    reviewed the warning and signed it. Officer Hatler then told Barnum that their
    business was done.
    Before Barnum returned to his rental vehicle, Officer Hatler engaged Barnum
    in a conversation concerning his prior involvement with drugs, his conviction for
    possession of a firearm by a felon, his current business, and his church. During this
    conversation, which occurred approximately twelve to fifteen minutes after the initial
    traffic stop, Officer Hatler asked Barnum if there was anything illegal in the vehicle
    and if he could search it. Barnum agreed to the search. For safety reasons, Officer
    Hatler patted Barnum down for weapons prior to searching the vehicle. The pat-down
    revealed no weapons, and Officer Hatler asked if he could search Barnum’s pockets.
    Barnum gave his permission, and Officer Hatler’s search revealed a crack pipe and a
    motel room key. Officer Hatler placed Barnum under arrest and finished his search
    of Barnum’s person, finding $305 in his shoe.
    -3-
    Officer Hatler held Barnum in the back of his patrol cruiser and asked a police
    dispatcher to send a female officer to conduct a pat-down of Pugh. After Officer
    Guffey arrived on the scene, Barnum volunteered that there was a gun in the rental
    vehicle that Barnum’s wife had given to Pugh. Officer Ward retrieved a cocked and
    loaded Titan .25 caliber semi-automatic handgun from the vehicle’s center console.
    Following this discovery, Officer Hatler read Barnum his Miranda3 rights, and Officer
    Ward arrested Pugh.
    A federal grand jury returned an indictment charging Barnum with being a felon
    in possession of a firearm in violation of 18 U.S.C. §§ 922(g)(1) and 924(a)(2).
    Barnum pled not guilty. Before trial, Barnum filed a motion to suppress his post-
    arrest, pre-Miranda statement concerning the handgun and the evidence seized from
    his person and his rental vehicle, claiming that Officer Hatler did not have probable
    cause for the traffic stop and that Barnum’s consent to the searches was not
    voluntarily given. At the motion hearing, the Government presented the testimonies
    of Officers Hatler and Ward concerning the circumstances of the traffic stop,
    Barnum’s consent to search, and the searches of his person and his rental vehicle.
    Barnum’s attorney cross-examined Officers Hatler and Ward concerning the
    circumstances under which Officer Hatler secured Barnum’s consent to search, the
    police department’s practice of checking vehicles in the Traveler Motel parking lot,
    and the officers’ explanations for the failure of their patrol-cruiser video cameras to
    record the traffic stop. Barnum also presented testimony that Kimberly Car City’s
    maintenance records reflected no reported problems with the Dodge Stratus’s center
    taillight either before or after the rental.
    The district court denied Barnum’s suppression motion, finding that Barnum
    voluntarily consented to the searches and that his consent sufficiently purged the taint
    of any potential Fourth Amendment violation arising from the allegedly illegal traffic
    3

    384 U.S. 436
    (1966).
    -4-
    stop. Because Barnum’s voluntary consent provided an independent justification for
    the searches, the district court refrained from deciding whether there was probable
    cause for the traffic stop. The district court also found that Barnum’s post-arrest, pre-
    Miranda statement to Officer Hatler concerning the handgun was not the product of
    interrogation. Following the court’s adverse ruling on his suppression motion,
    Barnum entered a conditional guilty plea pursuant to Federal Rule of Criminal
    Procedure 11(a)(2). The district court sentenced Barnum to 36 months’ imprisonment.
    II.   DISCUSSION
    Barnum appeals the district court’s denial of his suppression motion, arguing
    that the court clearly erred in finding that he voluntarily consented to the search of his
    person and his rental vehicle and that the court erred in finding that his consent purged
    the taint of any potential Fourth Amendment violation arising from the allegedly
    illegal traffic stop.4 “In an appeal of a denial of a motion to suppress evidence, the
    district court’s factual determinations are reviewed for clear error, and we review de
    novo its legal conclusions as to whether the Fourth Amendment has been violated.”
    United States v. Esquivel, 
    507 F.3d 1154
    , 1158 (8th Cir. 2007).
    Where applicable, the judicially-created exclusionary rule to the Fourth
    Amendment “forbids the use of improperly obtained evidence at trial.” Herring v.
    United States, 555 U.S. ---, 
    129 S. Ct. 695
    , 699 (2009).5 However, evidence subject
    to the exclusionary rule is still admissible if it is obtained through “an act of free will
    4
    Barnum abandoned any claim concerning his post-arrest, pre-Miranda
    statement about the location of the handgun by failing to argue the issue in his
    opening brief to this court. See United States v. Fischer, 
    551 F.3d 751
    , 756 (8th Cir.
    2008); United States v. Aldaco, 
    477 F.3d 1008
    , 1016 n.3 (8th Cir. 2007).
    5
    In deciding this appeal, we will assume that the exclusionary rule applies. See
    
    Herring, 129 S. Ct. at 700
    (noting “[t]he fact that a Fourth Amendment violation
    occurred . . . does not necessarily mean that the exclusionary rule applies”).

    unaffected by the initial illegality.” Brown v. Illinois, 
    422 U.S. 590
    , 603 (1975).
    Here, the Government argues that Barnum’s voluntary consent to search his person
    and his rental vehicle was an act of free will that purged the taint of any alleged Fourth
    Amendment violation arising from the traffic stop. Because the purported act of free
    will is the defendant’s consent to search, the Government must prove by a
    preponderance of the evidence that the defendant’s consent to search was voluntary
    and that the defendant’s consent was an act of free will sufficient to purge the taint of
    the Fourth Amendment violation. 
    Esquivel, 507 F.3d at 1160
    (citing 
    Brown, 422 U.S. at 603-04
    ); see also United States v. Kreisel, 
    210 F.3d 868
    , 869 (8th Cir. 2000). For
    the purposes of this inquiry, we assume that Officer Hatler violated the Fourth
    Amendment by effecting the traffic stop of Barnum’s rental vehicle without probable
    cause. See United States v. Grajeda, 
    497 F.3d 879
    , 882 (8th Cir. 2007) (assuming the
    existence of a Fourth Amendment violation in considering whether a defendant’s
    voluntary consent purged the taint of the alleged violation).
    A. Voluntary Consent to Search
    In United States v. Esquivias, we described our standard for deciding whether
    a defendant’s consent to search is voluntary:
    A court determines whether consent is voluntary under the totality of the
    circumstances. The Government . . . must show that the defendant
    behaved in such a manner that the officer reasonably believed that the
    search was consensual. In evaluating the reasonableness of the officer’s
    belief, we consider the characteristics of the person consenting, including
    the party’s age, intelligence and education, whether he was under the
    influence of drugs or alcohol, whether he was informed of his right to
    withhold consent, and whether he was aware of rights afforded criminal
    suspects. We also consider the environment in which the alleged consent
    took place, specifically (1) the length of time he was detained; (2)
    whether the police threatened, physically intimidated, or punished him;
    (3) whether the police made promises or misrepresentations; (4) whether
    -6-
    he was in custody or under arrest when the consent was given; (5)
    whether the consent occurred in a public or a secluded place; and (6)
    whether he stood by silently as the search occurred.
    
    416 F.3d 696
    , 700 (8th Cir. 2005) (internal citations, quotations and alterations
    omitted).
    Barnum contends that the district court clearly erred in finding that his consent
    to the searches was voluntary for two reasons: (1) Officer Hatler was unreasonable
    in his belief that a reasonable person would have felt free to disregard Officer Hatler’s
    request based on the presence of three police officers at the scene; and (2) Officer
    Hatler’s request to search Barnum’s rental vehicle was “loaded” in the sense that it
    was a compound question asked in a manner calculated to guarantee Barnum’s
    consent. We disagree.
    First, contrary to Barnum’s argument, the record shows that only two officers,
    Officers Hatler and Ward, were present when Barnum consented to the searches.
    Officer Guffey did not arrive on the scene until after Barnum consented to the
    searches. We have held that the mere presence of “two to three officers being armed
    with holstered firearms,” in the absence of evidence of threats or intimidation, does
    not negate a defendant’s consent. United States v. Va Lerie, 
    424 F.3d 694
    , 710 (8th
    Cir. 2005); see also United States v. Vera, 
    457 F.3d 831
    , 835 (8th Cir. 2006) (holding
    that a police officer’s mere presence without some “physical force or show of
    authority” does not establish that a reasonable person would not have felt free to
    disregard a police officer’s search request). The district court found, and Barnum does
    not dispute, that “he was not threatened, physically intimidated or punished by the
    police.” Because there is no evidence in the record showing that Officer Hatler or
    Officer Ward intimidated, threatened, or in any other way compelled Barnum to
    consent to the searches of his person and his rental vehicle, we reject Barnum’s first
    contention.
    -7-
    Second, even if we were to accept Barnum’s characterization of Officer Hatler’s
    request to search Barnum’s rental vehicle, we still would not find that the question
    guaranteed Barnum’s consent. Barnum’s “loaded” question theory is premised on a
    single piece of Officer Hatler’s testimony concerning his request to search Barnum’s
    rental vehicle: “I just asked him if there was anything illegal in the vehicle and if I
    could search it.” According to Barnum, the question’s compound phrasing placed him
    between Scylla and Charybdis, requiring him either to give consent or appear to be
    concealing contraband. However, Barnum’s premise does not support the conclusion
    that the question’s compound phrasing compelled Barnum to respond “yes.” A simple
    answer of “no” to Officer Hatler’s allegedly “loaded” question would have denied
    consent to the search and presumably terminated the encounter. Cf. Florida v.
    Bostick, 
    501 U.S. 429
    , 437 (1991) (“[A] refusal to cooperate, without more, does not
    furnish the minimal level of objective justification needed for a detention or seizure.”).
    In any event, Barnum’s second contention also fails because the allegedly
    compound question pertained only to the search of Barnum’s rental vehicle, not to the
    search of his person. After Barnum voluntarily consented to the search of his person,
    which revealed a crack pipe and $305 in cash, Officer Hatler placed Barnum under
    arrest. As a result, Officer Hatler could have properly searched Barnum’s rental
    vehicle, without his consent, for further evidence relevant to the drug offense for
    which Barnum had been arrested. See Arizona v. Gant, 556 U.S. ---, No. 07-542, slip
    op. at 10 (Apr. 21, 2009) (concluding that police may “search a vehicle incident to a
    recent occupant’s arrest” when “the arrestee is unsecured and within reaching distance
    of the passenger compartment at the time of the search” or when “it is ‘reasonable to
    believe evidence relevant to the crime of arrest might be found in the vehicle’”
    (quoting Thornton v. United States, 
    541 U.S. 615
    , 632 (2004) (Scalia, J., concurring
    in judgment))). Therefore, we reject Barnum’s second contention.
    Moreover, the record demonstrates that the personal and environmental factors
    set out in Esquivias support the district court’s finding that Barnum’s consent was
    -8-
    voluntary. At the time of the encounter, Barnum was thirty-nine years old and
    possessed some college education. See United States v. Comstock, 
    531 F.3d 667
    , 677
    (8th Cir.) (noting that the defendant’s status as an “adult, of apparently average
    intelligence” favored a finding that his consent was voluntarily given), cert. denied,
    555 U.S. ---, 
    129 S. Ct. 590
    (2008). Based on his previous arrests, we may infer that
    Barnum was aware of the rights afforded criminal suspects. See United States v.
    Griffith, 
    533 F.3d 979
    , 985 (8th Cir. 2008). Barnum was only detained for twelve to
    fifteen minutes before he gave his consent to the searches. See United States v.
    Becker, 
    333 F.3d 858
    , 861 (8th Cir. 2003) (holding that a thirty-minute detention
    before the defendant consented to the challenged search was “brief”). Officer Hatler
    did not threaten or intimidate Barnum and made no promises or misrepresentations to
    induce his consent. See 
    Griffith, 533 F.3d at 985
    . Barnum was situated behind his
    rental vehicle on the side of the road in broad daylight when he gave the consent, and
    he was not in police custody. See United States v. Flores, 
    474 F.3d 1100
    , 1104 (8th
    Cir. 2007) (finding that a daytime, roadside setting was not unduly coercive).
    Additionally, Barnum did not object to the searches at any time and was cooperative
    throughout the encounter. See 
    Becker, 333 F.3d at 861
    . Thus, the district court did
    not clearly err in finding that the totality of the circumstances demonstrated that
    Officer Hatler reasonably believed that Barnum voluntarily consented to the search
    of his person and his rental vehicle. See 
    Esquivias, 416 F.3d at 700-01
    .
    B. Purging the Taint of the Allegedly Illegal Traffic Stop
    “[A] voluntary consent to search, ‘which was preceded by an illegal police
    action, does not automatically purge the taint of an illegal detention.’” 
    Esquivel, 507 F.3d at 1160
    (quoting 
    Becker, 333 F.3d at 862
    ). To purge the taint, the voluntary
    consent must be an independent, lawful cause of the search, as determined by the three
    factors discussed in Brown v. Illinois: (1) the temporal proximity between the Fourth
    Amendment violation and the grant of consent to search; (2) the presence of any
    intervening circumstances; and (3) the purpose and flagrancy of the officer’s Fourth
    -9-
    Amendment violation. See 
    Brown, 422 U.S. at 603-04
    ; United States v. Herrera-
    Gonzalez, 
    474 F.3d 1105
    , 1111 (8th Cir. 2007).
    Here, although the district court did not make specific findings concerning each
    Brown factor, we can only conclude that the district court found that the Brown factors
    favored the Government based on the court’s citation to United States v. Esquivel and
    its conclusion that “the defendant’s subsequent voluntary consent [to the searches]
    under these circumstances rendered the issue regarding the validity of the initial stop
    irrelevant.” See 
    Esquivel, 507 F.3d at 1158-60
    (finding it unnecessary to address the
    validity of the traffic stop where the Brown factors demonstrated that the defendant’s
    voluntary consent purged the taint of the alleged Fourth Amendment violation); see
    also Walton v. Arizona, 
    497 U.S. 639
    , 653 (1990) (“Trial judges are presumed to
    know the law and to apply it in making their decisions.”), overruled on other grounds,
    Ring v. Arizona, 
    536 U.S. 584
    , 609 (2002).6 In reviewing such an implicit finding,7
    we will “uphold a district court’s decision on a motion to suppress despite [a] lack of
    factual findings if, on review of the record, [we] find that ‘any reasonable view of the
    6
    Contrary to the dissent’s assertion, the district court never erroneously
    “concluded as a matter of law that . . . it [was] unnecessary to make any factual
    findings concerning the disputed portions of the stop.” See post at 14, 16, 17-19.
    Instead, the district court correctly concluded that a finding of fact concerning whether
    Officer Hatler had probable cause to enact the traffic stop was unnecessary if
    Barnum’s voluntary consent purged the taint of any alleged Fourth Amendment
    violation. United States v. Barnum, No. 3:07-cr-0587, slip op. at 4 (S.D. Iowa Mar.
    31, 2008) (“[s]ubsequent events demonstrate that the issues in this case do not depend
    in any way upon the finding of probable cause to stop the vehicle” (emphasis added)).
    In so doing, the district court did not conclude that findings of fact concerning the
    other disputed portions of the traffic stop—those related to the voluntariness of
    Barnum’s consent or the purging the taint analysis—were unnecessary.
    7
    We agree with the dissent that specific findings of fact concerning the Brown
    factors would have assisted our review, and we suggest that the better practice is for
    a district court to make and identify all findings of fact necessary to its legal
    conclusion. See Fed. R. Crim. P. 12(d).
    -10-
    evidence supports the district court’s decision.’” See United States v. Bloomfield, 
    40 F.3d 910
    , 913-15 (8th Cir. 1994) (en banc) (alterations omitted) (quoting United
    States v. Harley, 
    990 F.2d 1340
    , 1341 (D.C. Cir. 1993)); see also United States v.
    Cortez-Palomino, 
    438 F.3d 910
    , 912 n.3 (8th Cir. 2006) (per curiam) (same).8
    In considering the first Brown factor, the temporal proximity between the
    Fourth Amendment violation and the grant of consent to search, we recognize that
    “the closer this period, the more likely the defendant’s consent was influenced by, or
    the product of, the police misconduct.” See United States v. Simpson, 
    439 F.3d 490
    ,
    495 n.3 (8th Cir. 2006). Here, the record demonstrates that Barnum gave his consent
    twelve to fifteen minutes after the allegedly illegal traffic stop. This twelve to fifteen
    minute interval supports a finding that the taint of any illegality was purged. See
    
    Esquivel, 507 F.3d at 1160
    (finding that a period of nine to ten minutes between “the
    time from which the stop became illegal to the time of the consent” suggested that the
    taint was purged); United States v. Palacios-Suarez, 
    149 F.3d 770
    , 773 (8th Cir. 1998)
    (finding that a nine-minute period between the start of the violation and the consent
    suggested that the taint was purged). Consequently, the first Brown factor favors the
    Government.
    Under the second Brown factor, the presence of any intervening circumstances,
    we recognize that an intervening circumstance between the Fourth Amendment
    violation and the defendant’s consent indicates that the consent was made of the
    defendant’s free will and “that the [officer] was not attempting to exploit an illegal
    situation.” 
    Grajeda, 497 F.3d at 882
    (quoting United States v. Moreno, 
    280 F.3d 898
    ,
    8
    Contrary to the dissent’s assertion, we need not and do not make any factual
    determinations concerning the Brown factors. See post at 14. Rather, we are charged
    with reviewing the record to determine whether the court’s legal conclusion—that
    Barnum’s consent purged the taint of any alleged Fourth Amendment violation—is
    supported by “any reasonable view of the evidence.” See 
    Bloomfield, 40 F.3d at 914
    -
    15.
    -11-
    901 (8th Cir. 2002)). Here, the record shows that Officer Hatler returned Barnum’s
    license and vehicle rental agreement and told Barnum that the traffic stop was over
    before asking to search his person and vehicle. Because this occurred after the
    allegedly illegal traffic stop but prior to Barnum’s consent, we find that Officer
    Hatler’s return of Barnum’s paperwork and his declaration that the traffic stop was
    over constitute intervening circumstances. See 
    Esquivel, 507 F.3d at 1160
    (“[T]he
    Trooper’s announcement that the traffic stop was over and [the defendant] was free
    to leave was also an intervening circumstance between the presumed illegal detention
    and the consent.”); cf. United States v. Jenson, 
    462 F.3d 399
    , 407 (5th Cir. 2006)
    (“[E]vidence that (a) [the defendant] knew he was free to leave or (b) that his license
    had been returned to him . . . might be viewed as intervening circumstances.”). Thus,
    the second Brown factor also favors the Government.
    With respect to the third Brown factor, the purpose and flagrancy of the
    officer’s Fourth Amendment violation, we recognize that a police officer’s purposeful
    or flagrant misconduct may demonstrate a causal connection between the violation
    and the consent. See 
    Brown, 422 U.S. at 603-04
    . A Fourth Amendment violation may
    be purposeful or flagrant under various circumstances, including where the violation
    “was investigatory in design and purpose and executed ‘in the hope that something
    might turn up.’” 
    Herrera-Gonzalez, 474 F.3d at 1113
    (quoting 
    Simpson, 439 F.3d at 496
    ). Here, a reasonable view of Officer Hatler’s testimony supports a finding that
    he did not act purposefully or flagrantly by initiating the allegedly illegal traffic stop.
    According to his testimony, Officer Hatler initiated the traffic stop as part of his
    routine patrol, doing so only after he observed the rental vehicle’s malfunctioning
    center taillight, a violation of Iowa Code § 321.387. Assuming, then, that Officer
    Hatler’s observation was objectively unreasonable,9 a reasonable view of Officer

    Our assumptions concerning the allegedly illegal traffic stop are limited to
    those necessary to establish a Fourth Amendment violation. See 
    Grajeda, 497 F.3d at 882
    . Here, we need only assume that Officer Hatler’s observation concerning the
    rental vehicle’s taillight was objectively unreasonable to establish the Fourth
    -12-
    Hatler’s testimony is that he initiated the stop because of an “unreasonable mistake
    of fact . . . [which] does not constitute the type of blatantly unconstitutional or flagrant
    behavior condemned in Brown.” See 
    Simpson, 439 F.3d at 496
    . Because a reasonable
    view of the evidence supports the district court’s implicit finding, we need not choose
    between this view and Barnum’s competing theory concerning the third Brown
    factor,10 nor must we remand for an explicit finding of fact. See 
    Bloomfield, 40 F.3d at 915
    (holding that remand is unnecessary where the district court states its legal
    basis for denying the motion to suppress on the record and a reasonable view of the
    evidence supports its decision). Thus, the third Brown factor also favors the
    Government.
    Because a reasonable view of the evidence demonstrates that the Brown factors
    favor the Government, we find that the district court did not err in its conclusion that
    Barnum’s voluntary consent to the searches purged the taint of any Fourth
    Amendment violation.
    III.   CONCLUSION
    For the foregoing reasons, we affirm Barnum’s conviction.
    Amendment violation. See 
    Herrera-Gonzalez, 474 F.3d at 1113
    . We need not and
    do not assume that Officer Hatler acted purposefully and flagrantly—that he knew the
    taillight was working or that he had any improper motive or malicious intent in
    initiating the traffic stop without probable cause. See 
    id. 10 Barnum
    argues that Officer Hatler acted purposefully and flagrantly by
    making an illegal traffic stop in the hope that a subsequent search would turn up
    illegal activity. Barnum bases his theory on Officer Hatler’s testimony that he knew
    of the Traveler Motel’s reputation for illegal activity, that he knew Barnum’s rental
    vehicle had been parked at the Traveler Motel, that he initiated the traffic stop as soon
    as the rental vehicle pulled out of the Traveler Motel parking lot, and that his cruiser
    video camera failed to record the traffic stop.

    BYE, Circuit Judge, dissenting.
    I dissent from the majority’s cavalier usurpation of the district court’s authority
    to make evidentiary findings on contested issues of fact. Barnum specifically argued
    to the district court that there was no probable cause for his traffic stop because his
    center taillight was functioning properly, and Officer Hatler knew it was working
    properly yet stopped him anyway in the hope of uncovering criminal activity. The
    district court concluded as a matter of law that “[s]ubsequent events demonstrate that
    the issues in this case do not depend in any way upon the finding of probable cause
    to stop the vehicle.” Thus, the district court found it unnecessary to make any factual
    findings concerning the disputed portions of the stop. As explained below, this
    conclusion of law is incorrect. Instead of correcting the district court’s erroneous
    legal conclusion, the majority—apparently recognizing it does in fact matter whether
    Officer Hatler purposely fabricated a reason for stopping Barnum—determines that,
    if there was a Fourth Amendment violation, it was only because Officer Hatler made
    a reasonable mistake of fact. By doing so, the majority assesses the record, assumes
    the district court implicitly made a factual finding that it expressly stated it was not
    making, and makes factual determinations that should have been made by, and are
    solely within the province of, the district court.
    I agree with the majority’s conclusion that Barnum’s consent was voluntary.
    Finding Barnum’s consent was voluntary, however, “is not the end of our inquiry.”
    United States v. Esquivel, 
    507 F.3d 1154
    , 1160 (8th Cir. 2007). “Because voluntary
    consent to search, which was preceded by an illegal police action, does not
    automatically purge the taint of an illegal detention, we must next determine if the
    voluntary consent was an independent, lawful cause of the discovery of the
    [incriminating evidence].” 
    Id. (internal quotation
    marks omitted). To determine
    whether the consent was sufficiently attenuated from the illegal detention, we
    consider: “(1) the temporal proximity of his consent and the prior Fourth Amendment
    violation; (2) the presence of intervening circumstances; and (3) the purpose and
    -14-
    flagrancy of the official misconduct.” United States v. Becker, 
    333 F.3d 858
    , 862 (8th
    Cir. 2003). Of these, “the purpose and flagrancy of the official misconduct is ‘the
    most important factor because it is directly tied to the purpose of the exclusionary
    rule–deterring police misconduct.’” United States v. Herrera-Gonzalez, 
    474 F.3d 1105
    , 1111 (8th Cir. 2007) (quoting United States v. Simpson, 
    439 F.3d 490
    , 496 (8th
    Cir. 2006)).
    We have “found purposeful and flagrant conduct where: (1) the impropriety of
    the official’s misconduct was obvious or the official knew, at the time, that his
    conduct was likely unconstitutional but engaged in it nevertheless; and (2) the
    misconduct was investigatory in design and purpose and executed in the hope that
    something might turn up.” Simpson, 
    439 F.3d 490
    , 496 (8th Cir. 2006). The majority
    correctly notes that we must presume Barnum’s center taillight was functioning
    properly. If we assume the taillight was working, there are two possible scenarios
    concerning the traffic stop: either Officer Hatler mistakenly concluded the taillight
    was malfunctioning, or he in fact knew it was working properly. I agree with the
    majority that if it is the former, then Officer Hatler’s unreasonable mistake of fact
    “does not constitute the type of blatantly unconstitutional or flagrant behavior
    condemned in Brown.” Ante at 13.11
    If, however, Officer Hatler was aware the taillight was functioning properly (or
    never bothered to look at the taillight) before stopping Barnum, then this is precisely
    the type of purposeful and flagrant misconduct that taints Barnum’s subsequent
    consent to search. If Officer Hatler simply fabricated a reason for stopping Barnum,
    then the impropriety of his misconduct would have been obvious, and he would have
    known such conduct was unconstitutional. Moreover, there would have been no
    11
    It is worth noting there is no evidence to explain how, if the taillight was
    functioning properly, Officer Hatler could have mistakenly concluded it was broke
    during the twenty seconds in which he was following directly behind Barnum’s
    vehicle.
    -15-
    purpose for fabricating a reason to stop Barnum other than to hope something might
    turn up. To rule otherwise would allow police officers to fabricate reasons for
    stopping motorists so long as the officers inform the suspects that the fabricated
    purpose of the stop is complete before obtaining their consent. If police officers stop
    motorists for reasons they know to be false, then those officers are engaging in
    conduct they know to be unconstitutional. Such a blatant disregard of constitutional
    rights taints any subsequent consent to search the officers may receive.
    Therefore, the district court incorrectly concluded as a matter of law that the
    circumstances of the stop were immaterial to Barnum’s motion to suppress. To the
    contrary, the circumstances of the stop were critical to ruling on the motion to
    suppress. Instead of correcting the legal error, recognizing the need for further
    findings of fact, and remanding to the district court, the majority engages in its own
    assessment of the evidence based upon a “reasonable view of Officer Hatler’s
    testimony.” Ante at 13. Even more remarkable, the majority—in a footnote—
    constructs an entirely new and legally unsupported rule in holding that our
    assumptions “are limited to those necessary to establish a Fourth Amendment
    violation” such that we “need not and do not assume that Officer Hatler acted
    purposefully and flagrantly—that he knew the taillight was working or that he had any
    improper motive or malicious intent in initiating the traffic stop without probable
    cause.” Ante at 13 n.9. The majority claims that, when a district court presumes a
    Fourth Amendment violation but fails to make any findings concerning the nature of
    the violation, this Court—if the specifics surrounding the violation are in fact
    relevant—will simply assume the least culpable conduct possible of violating the
    constitution.
    If the majority is relying on our statement in United States v. Bloomfield, 
    40 F.3d 910
    , 915 (8th Cir. 1994) (en banc), that we will affirm in the absence of express
    factual findings so long as “any reasonable view of the evidence supports the district
    court’s decision,” our subsequent cases have rejected the majority’s application of this
    -16-
    principle to the present case. The principle enunciated in Bloomfield generally applies
    when a district court correctly articulates the law and reaches a result such that certain
    factual findings are implicit in the lower court’s holding.12 For example, when the
    district court correctly articulates that the legal principle governing a motion to
    suppress is the existence of probable cause, and denies the motion to suppress without
    making factual findings, we can conclude the district court implicitly found probable
    cause, and we need not remand for express factual findings so long as any reasonable
    view of the evidence supports a finding of probable cause.
    If, however, the district court reaches an erroneous legal conclusion that it
    believes obviates the need for relevant factual determinations, we must correct the
    legal error and remand for further proceedings. In such cases, the “absence of an
    explicit factual finding . . . precludes us from resolving the appeal at this juncture.”
    United States v. Khabeer, 
    410 F.3d 477
    , 483 (8th Cir. 2005). The majority avoids this
    logic by stating it is simply “reviewing the record to determine whether the district
    court’s legal conclusion—that Barnum’s consent purged the taint of any alleged
    Fourth Amendment violation—is supported by any reasonable view of the evidence.”
    Ante at 11 n.8 (internal quotation marks and citation omitted). The majority, however,
    makes no mention of the district court’s preceding legal conclusion that “[s]ubsequent
    events demonstrate that the issues in this case do not depend in any way upon the
    12
    Notably, the district court in Bloomfield made some factual findings in favor
    of the government based on the police officer’s testimony, which indicated the court
    treated the officer’s testimony as credible. 
    Bloomfield, 40 F.3d at 915
    . In this case,
    the district court did not make any factual findings from which we can presume the
    court found any portion of Officer’s Hatler’s testimony to be credible. It is entirely
    possible the court found Officer Hatler’s testimony to be false, but still denied the
    motion based on its determination that the circumstances of the stop were irrelevant;
    as previously explained, such an interpretation of the law would be wrong.
    -17-
    finding of probable cause to stop the vehicle.”13 As discussed, this legal conclusion
    is incorrect. The majority ignores this erroneous statement of the law, and instead
    presumes that the unmade necessary factual findings—those the district court
    expressly stated it was not making—were implicitly determined in favor of the
    government. In doing so, the majority fails to heed the Supreme Court’s admonition
    that “it is the function of the District Court rather than the Court of Appeals to
    determine the facts.” Murray v. United States, 
    487 U.S. 553
    , 543 (1988).
    Because the district court’s result was premised solely on an erroneous legal
    conclusion, we should not scour an undeveloped record for any reasonable view of the
    evidence to support the district court’s result. Bloomfield is meant to apply when “the
    trial court omits a finding apparent on the face of the record, or when, under any
    possible view of the record, the district court could have reached but one result.”
    
    Bloomfield, 40 F.3d at 914
    (quoting United States v. Williams, 
    951 F.2d 1287
    , 1290-
    91 (D.C. Cir. 1991)). Had the district court correctly recognized that Barnum’s
    motion to suppress should be granted if Officer Hatler fabricated a reason for
    initiating the traffic stop, but denied his motion to suppress without making any
    findings concerning the stop, then we could presume the court implicitly determined
    the facts in favor of the government.
    In this case, however, the district court’s erroneous legal conclusion precludes
    application of Bloomfield and requires a remand to the district court. It defies logic
    for the majority to assume the district court implicitly made a specific factual finding
    13
    The majority claims this statement simply means the district court correctly
    concluded that a finding of probable cause was unnecessary if Barnum’s consent
    purged the taint of any Fourth Amendment violation. Ante at 10 n.6. Of course, this
    ignores the fact that whether Barnum’s consent purged the taint of the violation was
    dependent upon the finding of probable cause; if Officer Hatler knew there was no
    probable cause, then Barnum’s consent could not have purged the constitutional
    violation.
    -18-
    concerning Officer Hatler’s observations when the district court expressly
    stated—because of an incorrect legal conclusion— that it was not making any findings
    in that regard. It is one thing to apply Bloomfield to facts the court must have
    implicitly made, it is another thing entirely to apply Bloomfield to facts the court
    expressly declined to make. While doing so is a convenient method of pretending the
    district court’s erroneous legal conclusion had no effect on the outcome, convenience
    is no substitute for rigorous analysis and a just result.
    Moreover, the majority, in assessing the evidence, incorrectly implies Barnum’s
    theory lacks support in the record. Barnum presented maintenance records reflecting
    no reported problems with the taillight either before or after the traffic stop in
    question. In addition, employees of the service center testified it is common practice
    to check the taillight and to note any malfunction or necessary repairs on the service
    records for that vehicle. Furthermore, Officer Hatler had already come across
    Barnum’s vehicle in the parking lot of a hotel known as a frequent site of criminal
    activity, thereby increasing his motivation for stopping Barnum in the hope of
    uncovering criminal activity. In contrast, the only evidence the taillight was
    malfunctioning at the time of the stop was Officer Hatler’s testimony. In light of this
    evidence, the district court could conclude the taillight was working properly at the
    time of the stop. If it determines the light was working properly, the district court
    could also conclude Officer Hatler never believed the taillight was malfunctioning.
    Officer Hatler followed directly behind Barnum’s vehicle for twenty seconds, and it
    is hard to see how Officer Hatler could have mistakenly believed the taillight was not
    working properly. While the majority may have such faith in the sanctity of police
    officers to find such a scenario impossible as a matter of law, I believe the district
    court should resolve this contested factual issue. It is not our responsibility to
    determine which interpretation of the evidence is more reasonable. Rather, the district
    court should make its own factual findings relevant to Barnum’s motion to suppress,
    which we can then review for clear error.
    -19-
    I also disagree with the majority’s assessment of the temporal proximity factor.
    The majority states that Barnum gave his consent to search twelve to fifteen minutes
    after the allegedly illegal traffic stop. In doing so, the majority is calculating the time
    between when Officer Hatler first initiated the traffic stop and when Barnum gave his
    consent. This fails to recognize, however, that, if the traffic stop was unconstitutional,
    then the Fourth Amendment violation continued until the non-consensual portion of
    the encounter ended, i.e., when Officer Hatler returned Barnum’s paperwork and
    informed him that the purpose of the stop was complete. If we are assessing the taint
    of the Fourth Amendment violation, logic dictates that we should consider the time
    period between when the Fourth Amendment violation ends and when the consent to
    search is given. By concluding otherwise, courts reward officers for prolonging
    unconstitutional conduct. Therefore, in assessing the temporal proximity between the
    Fourth Amendment violation and the consent to search, I believe we should consider
    the time period from the end of the constitutional violation, not the beginning.14
    Accordingly, I dissent.
    ______________________________

    To the extent our precedent states otherwise, ante at 11, I believe such a rule
    is illogical, unsound, and should be reconsidered.
