    Before McMILLIAN, HEANEY, and MORRIS SHEPPARD ARNOLD,
    Circuit Judges.
    ___________
    McMILLIAN, Circuit Judge.
    Salwan Yousif appeals from a final judgment entered in the United States
    District Court for the Eastern District of Missouri upon his conditional plea of guilty
    to one count of possession with intent to distribute more than 100 kilograms of
    marijuana, in violation of 21 U.S.C. § 841(a)(1). On appeal, Yousif challenges the
    district court’s denial of his motion to suppress physical evidence and statements
    obtained by law enforcement officers when his vehicle was stopped and searched at
    a drug interdiction checkpoint. For reversal, Yousif argues that, although the district
    court correctly held that the drug interdiction checkpoint program violated the Fourth
    Amendment under City of Indianapolis v. Edmond, 
    531 U.S. 32
    (2000) (Edmond),
    and that he was stopped illegally, the district court erred in concluding that he
    voluntary consented to the search of his vehicle so as to purge the taint of the primary
    illegality. The government argues, in response, that no Fourth Amendment violation
    occurred and, even if one did, the district court correctly held that Yousif’s voluntary
    consent to the search of his vehicle purged the taint of the constitutional violation.
    For the reasons discussed below, we hold that the district court erred in denying
    Yousif’s motion to suppress. Accordingly, we vacate the judgment of the district
    court and remand the case to the district court for further proceedings consistent with
    this opinion.
    Jurisdiction
    Jurisdiction in the district court was proper based upon 18 U.S.C. § 3231.
    Jurisdiction in this court is proper based upon 28 U.S.C. § 1291. The notice of appeal
    was timely filed pursuant to Fed. R. App. P. 4(b).
    Background
    On April 27, 2000, Yousif was indicted in the district court on one count of
    possession with intent to distribute over 100 kilograms of marijuana. Yousif moved
    to suppress physical evidence and statements, and the matter was referred to a
    magistrate judge. Based upon the evidence presented at an evidentiary hearing, the
    magistrate judge issued a report containing detailed findings of fact and
    recommended conclusions of law. United States v. Yousif, 4:00 CR 208 (E. D. Mo.
    Sept. 15, 2000) (Yousif) (hereinafter “Mag. Rep. I”) The following is a summary of
    the background facts, as found by the magistrate judge. 
    Id. at 1-8.
    -2-
    On April 13, 2000, the Missouri Highway Patrol (MHP) and the Phelps County
    Sheriff’s Department set up a drug interdiction checkpoint at the end of the exit ramp
    leading uphill from eastbound Interstate Highway 44 (“I-44”) to Sugar Tree Road in
    Phelps County, Missouri (hereinafter “the Sugar Tree Road checkpoint”. The Sugar
    Tree Road checkpoint was a so-called “ruse checkpoint” because signs were placed
    along the highway warning travelers that they were approaching a drug checkpoint
    further down the highway, yet the checkpoint was actually located on the ramp which
    exited the highway a short distance past the signs. The Sugar Tree Road exit was
    chosen as a site for a ruse checkpoint because law enforcement officers believed that
    I-44 was a commonly used route for transporting drugs, there was little use of the
    Sugar Tree Road exit for commercial or local traffic, and the end of the ramp was not
    visible from the highway.
    Operation of the Sugar Tree Road checkpoint was governed by a set of
    standard procedures set forth in a memorandum issued by the MHP on April 4, 2000
    (hereinafter “the MHP memorandum”). Pursuant to the MHP memorandum, the
    following procedures were implemented. Approximately one-quarter mile west of the
    Sugar Tree Road exit, signs were placed on each shoulder of the road, stating: “Drug
    Enforcement Checkpoint 1/4 Mile Ahead.” Further down the road, approximately
    100 yards west of the Sugar Tree Road exit, more signs were placed alongside of the
    road, stating: “Drug Dogs in Use Ahead.” The checkpoint was set up at the end of
    the Sugar Tree Road exit ramp, out of view from I-44. At least two fully marked
    MHP patrol cars were located at the checkpoint. When a vehicle would arrive at the
    checkpoint, at least one uniformed officer would approach the driver and ask for his
    or her driver’s license, registration, and – if required by the state of registration –
    proof of insurance. The officer would also record the license plate number of the
    vehicle and ask the driver if he or she saw the signs and why he or she exited the
    highway. Upon perceiving any indication of illegal activity, the officer would
    question the driver further. If there were any reason to believe that the vehicle
    contained illegal drugs or other contraband, the officer would ask for consent to
    -3-
    search the vehicle. If consent were denied, but the officer still had a reasonable
    suspicion of unlawful activity, the officer would ask the occupants to step out of the
    vehicle. The officer would then turn off the ignition and have a drug dog walk
    around the exterior of the vehicle. If the dog failed to alert, and the officer had no
    other reason to hold the vehicle and its occupants, they would be allowed to leave.
    On April 13, 2000, officers with the MHP and Phelps County Sheriff’s
    Department had set up the Sugar Tree Road checkpoint as described above. Shortly
    before 3:00 p.m., MHP Patrolman Richard Lisenbe observed Yousif’s Ford Explorer
    with Oklahoma license plates turn from I-44 onto the Sugar Tree Road exit ramp.
    Lisenbe was dressed in uniform and standing with other officers at the top of the
    ramp. A sign indicating the presence of a police checkpoint, as well as two MHP
    patrol cars, were clearly visible to the vehicle as it approached the end of the Sugar
    Tree Road exit ramp. The Explorer slowed, coming nearly to a stop halfway up the
    ramp. Lisenbe waved his arm directing the driver, Yousif, to proceed forward. After
    the Explorer stopped at the checkpoint, as directed, Lisenbe and two other officers
    approached the vehicle. Upon reaching the open driver’s side window, Lisenbe
    noticed a strong berry-like odor. Lisenbe asked Yousif for his driver’s license,
    registration, and proof of insurance. Yousif produced an Arizona driver’s license and
    a rental agreement for the vehicle. According to Lisenbe, Yousif’s hands were
    shaking and he nearly dropped his license as he was trying to hand it over. Lisenbe
    considered it unusual for a rental car to have such a strong odor. When Lisenbe asked
    Yousif why he had exited the highway, Yousif’s wife, who was in the passenger seat,
    volunteered that they had exited to let their dog relieve itself.
    Lisenbe asked Yousif if he had anything illegal in the vehicle, including
    narcotics. Yousif said he did not. Lisenbe then asked Yousif if he consented to a
    search of the vehicle and its contents, and Yousif told him to go ahead. At that point,
    Yousif’s wife asked Lisenbe if he could search without a warrant. Lisenbe replied,
    in Yousif’s presence, that the police could conduct a search if they were given
    -4-
    consent or had probable cause. Yousif’s wife then said: “That’s OK, I was just
    asking.” No threats or promises were made by any of the officers in order to obtain
    Yousif’s consent to the vehicle search, and neither he nor his wife objected.
    Lisenbe opened the back of the Explorer and found six large black suitcases
    under a blanket and pillows. Inside the suitcases were bundles of green plant material
    appearing to be marijuana. Lisenbe then placed Yousif and his wife under arrest and
    advised them of their Miranda rights. Lisenbe asked them if they understood these
    rights, and they said that they did. Lisenbe asked Yousif and his wife if they wanted
    to cooperate with investigators, and Yousif said he did. Lisenbe motioned over two
    plain-clothed police officers. In Yousif’s presence, Lisenbe informed the two officers
    that marijuana had been found in the car, that Yousif was willing to make a statement,
    and that Yousif had been read his Miranda rights. Yousif said nothing. Lisenbe also
    showed the officers the marijuana found in the back of the Explorer.
    The two officers walked Yousif to a motor home which the officers were using
    as an on-site office. Inside the motor home, one of the officers began questioning
    Yousif, and Yousif began providing information regarding his involvement with the
    marijuana. While the interview was proceeding, Lisenbe interrupted and stated that,
    because of the need to secure the marijuana, they should continue the interview at the
    Highway Patrol Troop I Headquarters in Rolla, Missouri. Accordingly, Yousif, his
    wife, and the Explorer were taken to the Troop I headquarters in Rolla, where the
    interview was resumed.
    While Yousif was being questioned by one of the officers at the Troop I
    headquarters, Yousif asked whether he should speak with an attorney. The officer
    responded that he had a right to speak with an attorney and, if he so desired, the
    interview would be terminated. The officer further stated: “That was told to you
    when you were read your rights.” At that point, Yousif denied having been read his
    Miranda rights. The officer then reminded him that he had been read his Miranda
    -5-
    rights by Lisenbe while they were at the Sugar Tree Road checkpoint. Yousif again
    denied having been advised of his rights. The interviewing officer then sent another
    officer to find Lisenbe, to specifically ask Lisenbe whether Yousif had been read his
    Miranda rights. Lisenbe confirmed that he had. The officer questioning Yousif read
    Yousif his Miranda rights a second time, and again asked him if he understood them.
    Yousif said that he did and indicated that he wanted to continue with the interview.
    Afterward, Yousif twice inquired during the interview about the deal he would
    receive in exchange for the information he was providing. Each time he was told that
    the prosecutor would make that determination upon assessing the information Yousif
    was providing. The second time, Yousif stated that, if he could not be assured of a
    deal, he did not want to cooperate. At that point, the interview was terminated.
    Based upon these facts, the magistrate judge concluded that: (1) the stop of
    Yousif’s vehicle at the Sugar Tree Road checkpoint did not violate the Fourth
    Amendment and (2) Yousif’s consent to the search of his vehicle was voluntary.
    Mag. Rep. I at 11-15. Accordingly, the magistrate judge recommended that the
    motion to suppress be denied. Yousif objected to the magistrate judge’s report and
    recommendation. By order dated October 18, 2000, the district court adopted the
    magistrate judge’s report and recommendation and denied Yousif’s motion to
    suppress. Shortly thereafter, however, the United States Supreme Court issued its
    decision in 
    Edmond, 531 U.S. at 40-48
    , holding that drug interdiction roadside
    checkpoints being used by the City of Indianapolis violated the Fourth Amendment
    because they resulted in seizures that were not based upon individualized reasonable
    suspicion and were set up by law enforcement officers for the primary purpose of
    interdicting narcotics traffic, which, the Court explained, was essentially for the
    purpose of general crime control.1 Yousif thereafter moved in the district court for
    1
    The Supreme Court distinguished the drug interdiction checkpoints at issue
    in City of Indianapolis v. Edmond, 
    531 U.S. 32
    , 41 (2000) (Edmond), from those
    which were for “purposes closely related to the problems of policing the border or the
    necessity of ensuring roadway safety,” which the Court had previously approved.
    -6-
    reconsideration of his motion to suppress. The district court granted the motion and
    referred the matter back to the magistrate judge.
    Upon reconsideration in light of Edmond, the magistrate judge again
    recommended denial of Yousif’s motion to suppress. The magistrate judge
    distinguished the case at bar from Edmond on the ground that, in the present case, the
    police did have an individualized reasonable suspicion of illegal activity based upon
    Yousif’s conduct as he approached the Sugar Tree Road checkpoint. Thus, the
    magistrate judge concluded that the initial seizure was not unconstitutional under the
    particular facts of this case. The magistrate judge reasoned:
    [D]efendant Yousif’s turning off Interstate 44, onto the Sugar Tree Road
    exit, after seeing the drug checkpoint signs, reasonably indicated to the
    officers that he was attempting to evade the police drug checkpoint
    investigation . . . . This suspicion that defendant was evading the police
    was bolstered by the officer’s observation that, as he drove up the Sugar
    Tree Road exit ramp, in a vehicle with out-of-state license plates,
    defendant slowed his vehicle almost to a stop half-way up the ramp.
    The officer then had to wave his arm and direct Yousif to continue
    driving up the ramp to the checkpoint before he did so. Common sense
    indicates that defendant possibly was evading police detection of his
    illicit drug activity.
    Yousif, slip op. at 13 (Dec. 12, 2000) (hereinafter “Mag. Rep. II”) (citing Illinois v.
    Wardlow, 
    528 U.S. 119
    (2000) (Wardlow)2). In any event, the magistrate judge
    2
    In Illinois v. Wardlow, 
    528 U.S. 119
    (2000), the Supreme Court held that a
    Terry stop was sufficiently supported by reasonable suspicion of criminal activity
    where the defendant was in an area known for heavy narcotics trafficking and fled
    without provocation upon noticing that police were patrolling the area. The Court
    reasoned: “Headlong flight–wherever it occurs–is the consummate act of evasion: It
    is not necessarily indicative of wrongdoing, but it is certainly suggestive of such.”
    
    Id. at 124.
    -7-
    reasoned, even if the stop was unlawful under Edmond, the government had met its
    burden to prove that the evidence was admissible based upon Yousif’s consent to the
    search of the vehicle. That independent and voluntary consent, the magistrate judge
    concluded, was sufficient to purge the evidence in question of any taint resulting from
    the initial seizure. Mag. Rep. II at 13-14. Yousif filed objections to the magistrate
    judge’s second report and recommendation.
    Upon review, the district court disagreed with the magistrate judge’s
    conclusion that the officers had sufficient individualized suspicion to justify the stop
    of Yousif’s vehicle at the Sugar Tree Road checkpoint. The district court held that
    the Sugar Tree Road checkpoint was itself “clearly illegal” under Edmond and,
    moreover, that the Supreme Court’s holding in Edmond could not be “avoided”
    simply by relying on “factual indicators” which purportedly established
    individualized reasonable suspicion that Yousif was transporting drugs. Yousif, slip
    op. at 2 & n.1 (Jan. 8, 2001) (hereinafter “District court order”). The district court
    explained: “All of these indicators, [i.e.,] Defendant’s initial hesitation when he
    exited Interstate 44 and encountered the checkpoint, Defendant’s nervousness and
    shaking when questioned by Sergeant Lisenbe, and the overwhelming berry-scented
    air freshener, would not exist but for the illegal checkpoint.” 
    Id. Therefore, the
    district court concluded: “the officers did not have independent individualized
    suspicion that would overcome the illegality of the drug interdiction checkpoint.” 
    Id. (citing Wardlow).
    However, the district court agreed with the magistrate judge’s finding that
    Yousif’s voluntary consent to the search of his vehicle nevertheless provided an
    independent basis for denying the motion to suppress. See 
    id. at 3
    (“The Eighth
    Circuit has consistently held that voluntary consent purges the taint of an illegal
    search and seizure. . . . The Court adopts the Magistrate Judge’s factual findings with
    respect to Defendant’s consent and finds that defendant freely gave his consent to
    -8-
    search the truck.”) (citations omitted). Accordingly, the district court denied Yousif’s
    motion to suppress. 
    Id. Thereafter, Yousif
    entered a conditional plea of guilty, and the district court
    sentenced him to thirty-seven months in prison, four years supervised release, and a
    special assessment of $100. This appeal followed.
    Discussion
    Yousif argues on appeal that the district court erred in denying his motion to
    suppress. He maintains that, under Edmond, his Fourth Amendment rights were
    violated when he was stopped and detained at the Sugar Tree Road checkpoint and,
    moreover, the apparent consent he gave for the subsequent search of his vehicle and
    his apparent waiver of Miranda rights prior to making incriminating statements were
    not sufficiently attenuated from the unlawful seizure to purge the taint of the
    constitutional violation. Therefore, he concludes, the marijuana discovered in the
    Explorer and the statements he made to the officers were fruits of the poisonous tree
    and subject to exclusion under Wong Sun v. United States, 
    371 U.S. 471
    (1963)
    (Wong Sun).
    In response, the government asserts the following alternative grounds for
    affirming the district court’s ruling: (1) the Sugar Tree Road checkpoint was not
    illegal under Edmond; (2) even if it was, Lisenbe had reasonable suspicion under the
    totality of the circumstances to stop Yousif’s vehicle before it ever reached the Sugar
    Tree Road checkpoint; and (3) even if the initial stop and detention were illegal, any
    resulting taint was purged by the voluntariness of Yousif’s consent to the search of
    his vehicle and the voluntariness of his statements to the police after receiving
    Miranda warnings.
    -9-
    Constitutionality of the checkpoint program
    We review the district court’s conclusions of law de novo and its findings of
    fact for clear error. See, e.g., United States v. Booker, 
    269 F.3d 930
    (8th Cir. 2001).
    In Edmond, a class action brought on behalf of all motorists stopped or subject to
    being stopped at the Indianapolis drug checkpoints, the Supreme Court held that the
    Indianapolis checkpoint program violated the Fourth Amendment because it operated
    for the purpose of uncovering evidence of ordinary criminal wrongdoing (drug
    trafficking) without individualized reasonable suspicion. The Sugar Tree Road
    checkpoint program, as it was operated in the present case, similarly violated the
    Fourth Amendment insofar as its primary purpose was the interdiction of drug
    trafficking (which the government concedes) and the officers operating the Sugar
    Tree Road checkpoint were under instructions to stop every vehicle that took the
    Sugar Tree Road exit. While the checkpoint at issue in the present case differs from
    the checkpoint at issue in Edmond in that the MHP used signs to suggest to drivers
    that taking the Sugar Tree Road exit was a way to avoid a police checkpoint, the mere
    fact that some vehicles took the exit under such circumstances does not, in our
    opinion, create individualized reasonable suspicion of illegal activity as to every one
    of them. Indeed, as the government’s evidence indicated, while some drivers may
    have wanted to avoid being caught for drug trafficking, many more took the exit for
    wholly innocent reasons – such as wanting to avoid the inconvenience and delay of
    being stopped or because it was part of their intended route. See Mag. Rep. I at 2-3.3
    3
    According to statistical evidence presented by the government, during 54
    randomly selected days in 1997, a total of 2,537 vehicles were stopped at the Sugar
    Tree Road checkpoint. More than half (1,755) were driven by persons engaged in
    local motor vehicle traffic and, from those, 45 persons were detained and 4 were
    issued summonses for law violations. From the 644 vehicles that were not engaged
    in local traffic, 501 arrests occurred, including 395 arrests for drug violations – of
    which 339 were for misdemeanors. From the 2,537 vehicles stopped, 42 “loads” of
    controlled substances (i.e., amounts apparently intended for distribution as opposed
    to personal use) were discovered. See United States v. Yousif, 4:00 CR 208, slip op.
    -10-
    General profiles that fit large numbers of innocent people do not establish reasonable
    suspicion. See, e.g., United States v. Eustaquio, 
    198 F.3d 1068
    , 1071 (8th Cir. 1999)
    (Eustaquio). Without first stopping the vehicles and questioning the drivers, the
    police had no way to determine why any particular vehicles were exiting at the Sugar
    Tree Road ramp. Finding a quantum of individualized suspicion only after a stop
    occurs cannot justify the stop itself. “That result would have the same essential vice
    as a proposition we have consistently rejected – that a search unlawful at its inception
    may be validated by what it turns up.” Wong 
    Sun, 371 U.S. at 484
    .
    Individualized reasonable suspicion to justify the stop
    The government nevertheless argues that, even if the Sugar Tree Road
    checkpoint was generally illegal under Edmond, the totality of the circumstances
    noted by Lisenbe prior to the stop of Yousif’s vehicle sufficed to create
    individualized reasonable suspicion, thereby rendering the stop in this particular case
    constitutionally permissible. The government emphasizes that Yousif was driving on
    a highway that was known to be used for drug trafficking, his car had out-of-state
    license plates, he pulled off at a rural exit immediately after seeing signs warning of
    a drug checkpoint ahead, and he slowed almost to a complete stop upon seeing the
    police checkpoint ahead. Brief for Appellee at 18, 20.
    “Stopping an automobile and detaining its occupants constitute a ‘seizure’
    within the meaning of the [Fourth and Fourteenth] Amendments, even though the
    purpose of the stop is limited and the resulting detention quite brief.” Delaware v.
    Prouse, 
    440 U.S. 648
    , 653 (1979). Where law enforcement officers are not acting for
    a special purpose such as patrolling the borders or roadway safety, it is unreasonable
    at 2-3 (E. D. Mo. Sept. 15, 2000). Apparently no evidence was provided by the
    government as to the number of actual convictions resulting from the 395 drug-
    related arrests.
    -11-
    under the Fourth Amendment to stop a vehicle and detain its driver to check his or her
    license and registration, unless the officers have at least articulable and reasonable
    suspicion that the driver is not licensed, that the automobile is not registered, or that
    the automobile or one of its occupants is otherwise subject to seizure for a violation
    of the law. 
    Id. at 663.
    In the present case, the stop and detention of Yousif’s vehicle
    was therefore unreasonable under the Fourth Amendment unless Lisenbe had such
    reasonable and articulable suspicion before he executed the stop. The facts that
    Yousif’s vehicle had out-of-state license plates and was traveling on a highway that
    was “known” to the officers as a drug trafficking corridor cannot alone justify the
    stop because “[t]oo many people fit this description for it to justify a reasonable
    suspicion of criminal activity.” United States v. Gray, 
    213 F.3d 998
    , 1001(2000)
    (Gray) (quoting 
    Eustaquio, 198 F.3d at 1071
    ). As to the additional facts that Yousif
    took an exit just past the ruse checkpoint warning signs and then slowed down upon
    observing the actual checkpoint, we are chary to conclude that these provide
    sufficient additional circumstances to justify the intrusion. We first note that these
    circumstances never would have arisen but for the existence of the illegal checkpoint.
    Moreover, because there is nothing inherently unlawful or suspicious about a vehicle
    (even one with out-of-state license plates) exiting the highway, it should not be the
    case that the placement of signs by the police in front of the exit ramp transforms that
    facially innocent behavior into grounds for suspecting criminal activity. Reasonable
    suspicion cannot be manufactured by the police themselves. Cf. Wong 
    Sun, 371 U.S. at 485
    (“A contrary holding here would mean that a vague suspicion could be
    transformed into probable cause for arrest by reason of ambiguous conduct which the
    arresting officers themselves have provoked.”). Finally, the checkpoint was not
    where the police signs indicated it would be and, therefore, any motorist would likely
    be surprised upon discovering it. Under such circumstances, even an innocent
    traveler might be inclined to hesitate out of surprise, annoyance, or nervousness. We
    believe that Yousif’s hesitancy, while relevant, is materially distinguishable from the
    conduct that was at issue in 
    Wardlow, 528 U.S. at 124
    , where the defendant engaged
    in “unprovoked flight upon seeing the police.” See also United States v. Clay, 640
    -12-
    F.2d 157, 160 (8th Cir. 1981) (“The government’s emphasis that appellant’s
    ‘hesitancy’ created individualized suspicion falls far short of those cases dealing with
    flight.”). In sum, giving due regard to the general expertise and specific knowledge
    of the law enforcement officers involved, we nevertheless hold that the totality of the
    circumstances cited by the government did not support a reasonable suspicion, prior
    to the stop, that Yousif was engaged in criminal activity.4 Cf. 
    Gray, 213 F.3d at 1000
    -
    01 (holding that reasonable suspicion finding was not supported by the totality of
    circumstances cited by the government, including facts that the defendant was
    standing on the street in a high-crime area at night, in cold weather, and hurried
    across the street upon seeing law enforcement officers). We hold that the initial stop
    and detention of Yousif’s vehicle and its occupants constituted an unlawful seizure
    under the Fourth Amendment.
    Voluntariness of consent to search
    Evidence that is the “fruit” of an illegal search or seizure is not admissible, and
    “[t]he exclusionary prohibition extends as well to the indirect as the direct products
    of such invasions.” Wong 
    Sun, 371 U.S. at 484
    -85. The controlling question is
    “‘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.’” 
    Id. at 488

    By contrast, in a recent 4-3 decision, the Missouri Supreme Court
    distinguished a ruse checkpoint similar to the Sugar Tree Road checkpoint from the
    drug checkpoints at issue in Edmond and held that police officers did not violate the
    defendant’s Fourth Amendment rights when they stopped his vehicle at a ruse
    checkpoint. State v. Mack, 
    66 S.W.3d 706
    (Mo. 2002) (en banc). The Missouri
    Supreme Court concluded that the officers who carried out the stop had the necessary
    quantum of individualized suspicion, based in large part upon the reasoning that all
    drivers transporting drugs would exit the highway in order to avoid police detection.

    did not apply to the evidence at issue, notwithstanding the initial illegal seizure,
    because Yousif “freely gave his consent” to the search of his vehicle, thereby purging
    the taint of the constitutional violation. District court order at 3 (adopting the
    magistrate judge’s factual findings with respect to Yousif’s consent, and holding that
    the evidence in question would not be suppressed). Yousif argues that the district
    court clearly erred in holding that his consent to the search was “voluntary.” He
    further contends that there were insufficient intervening events or attenuating
    circumstances to purge the taint of the illegal seizure.
    The district court’s finding that Yousif voluntarily consented to search of his
    vehicle is reviewed for clear error. United States v. Moreno, 
    280 F.3d 898
    , 900 (8th
    Cir. 2002) (Moreno). It was the government’s burden to prove, by a preponderance
    of the evidence, that Yousif’s consent to the search was, in fact, voluntary in the sense
    that it was sufficiently an act of free will to purge the primary taint of the illegal
    seizure. See 
    id. Whether consent
    to a search is truly an act of free will must be
    determined on the facts of each case, under the totality of the circumstances. 
    Id. Our cases
    recognize that the following three factors should be considered: (1) the
    temporal proximity between the illegal search or seizure and the consent, (2) the
    presence of intervening circumstances, and (3) the purpose and flagrancy of the
    official misconduct. 
    Id. (citing Brown
    v. Illinois, 
    422 U.S. 590
    (1975) (identifying
    relevant factors)).
    In 
    Moreno, 280 F.3d at 899-900
    , a sheriff pulled over a vehicle driven by the
    defendant, Moreno, because the sheriff mistakenly thought that the temporary license
    plates on the vehicle were invalid. After requesting a driver’s license, the trooper
    discovered that Moreno did not have a valid driver’s license. The trooper issued
    Moreno a ticket for driving without a valid license and asked for permission to search
    the vehicle. At the suppression hearing, the trooper testified that he told Moreno that
    he did not have to consent to the search and that he even advised Moreno to refuse
    to consent if there were drugs in the vehicle. See 
    id. at 900
    (quoting the trooper’s
    -14-
    testimony: “What I always tell them, if ya, if ya have drugs in your car, don’t, don’t
    consent to a search”). Moreno consented to the search, and the trooper’s initial search
    turned up nothing illegal. The trooper then asked for, and Moreno provided,
    permission to have the vehicle towed and searched further. A second search at a
    service station yielded approximately 4 kilograms of methamphetamine hidden inside
    the vehicle. Upon being charged with possession with intent to distribute, Moreno
    moved to suppress the drugs. The district court determined that the sheriff, who was
    simply unfamiliar with the temporary tags at the time of the initial stop, lacked
    articulable reasonable suspicion of unlawful conduct and, therefore, stopped the
    vehicle in violation of Moreno’s Fourth Amendment rights. However, the district
    court further concluded that Moreno’s consent to the search of his vehicle was
    voluntary and purged the taint of the illegal stop. 
    Id. at 900.
    On appeal, this court
    assumed without deciding that the initial stop was illegal because that determination
    was not disputed by the government. 
    Id. at 900
    n.4. The only question was whether
    the district court had clearly erred in finding that the defendant had voluntarily
    consented to the search of his vehicle such that the taint of the illegal stop had been
    purged. In holding that the district court had not clearly erred, this court considered
    the three Brown factors mentioned above and noted, among other things, that the
    trooper had asked for and received consent to search the vehicle two separate times,
    that there was a considerable passage of time between the illegal stop and the second
    time the defendant gave his consent, that the trooper specifically told Moreno that he
    could refuse to consent to the search, and that there was no indication of bad faith or
    trickery, or purposeful or flagrant illegality, on the trooper’s part. 
    Id. at 901.
    In applying the Brown factors to the case at bar, we note that little time elapsed
    between the initial stop of Yousif’s vehicle and Yousif’s consent to the search.
    Moreover, there were no significant intervening events supporting a finding of
    voluntariness. We disagree with the government’s argument that Officer Lisenbe’s
    statement to Yousif – that a search could be conducted if the police had consent or
    probable cause – was an attenuating circumstance which added to the voluntariness
    -15-
    of Yousif’s consent. See Brief for Appellee at 24. On the contrary, a reasonable and
    most likely inference for Yousif to have drawn from Lisenbe’s statement was that, if
    Yousif refused to consent to the search, the officers would search the vehicle anyway,
    on the basis of probable cause. Cf. United States v. Morgan, 
    270 F.3d 625
    , 631 (8th
    Cir. 2001) (consent held not voluntary where trooper asked for consent to search a
    van, and the driver said “go ahead” after the trooper stated he would walk a drug dog
    around the van if consent were refused). Lisenbe’s statement was significantly
    different from the trooper’s statements in Moreno, advising Moreno that he could
    refuse to consent to the search. Accord United States v. Ramos, 
    42 F.3d 1160
    , 1164
    (8th Cir. 1994) (finding that written consent to search was voluntary under Wong Sun,
    notwithstanding prior illegal detention, where “[t]he officer told [the defendant], both
    orally and in writing, that he did not have to sign the consent form”), cert. denied, 
    514 U.S. 1134
    (1995). Finally, while we attribute no bad faith to the officers, we
    emphasize that the checkpoint program was, in its entirety, operating in violation of
    the law. The very purpose of the checkpoint was to root out vehicles on the road
    carrying illegal narcotics. Although the officers were not purposefully violating the
    Fourth Amendment, the search of Yousif’s vehicle was carried out exactly as planned
    under the guidelines for the illegal checkpoint, and it can hardly be disputed that the
    search of Yousif’s vehicle thus resulted from an exploitation of illegal circumstances.
    The presence of patrol cars, numerous uniformed officers, and drug dogs made the
    illegal circumstances flagrant, and rendered the overall atmosphere of the checkpoint
    intimidating and coercive. In sum, we hold that the district court clearly erred in
    finding, under the totality of the circumstances, that Yousif’s consent to the search
    of his vehicle was sufficiently an act of free will to be deemed voluntary.
    Accordingly, we hold that Yousif’s consent did not purge the primary taint of the
    illegal stop.
    -16-
    Voluntariness of statements to police
    As stated above, Yousif also moved to suppress the statements he made to the
    police following the discovery of marijuana in his vehicle. The district court did not
    specifically decide the question of whether Yousif’s statements to the police could
    independently be admitted if the drugs were suppressed, because the district court
    held that Yousif’s consent to the search of his vehicle purged the taint of the primary
    illegality. Yousif maintains on appeal that, in addition to the marijuana found in the
    vehicle, his statements were fruit of the poisonous tree and subject to exclusion
    notwithstanding his waiver of Miranda rights. He argues, among other things, that
    a Miranda warning will not always break the causal connection between a Fourth
    Amendment violation and a confession. See Brown v. Illinois, 
    422 U.S. 590
    , 603
    (1975).
    Verbal statements obtained as a result of a Fourth Amendment violation are as
    much subject to the exclusionary rule as are items of physical evidence discovered
    during an illegal search. Wong 
    Sun, 371 U.S. at 485
    (“the Fourth Amendment may
    protect against the overhearing of verbal statements as well as against the more
    traditional seizure of ‘papers and effects’”). In the present case, the lower courts’
    findings indicate that there were intervening events and attenuating circumstances
    with respect to Yousif’s statements that were not present at the time Lisenbe sought
    his consent to the search. Nevertheless, because the district court did not reach the
    question of whether Yousif’s statements to the police could independently be
    admitted even if the drugs were suppressed, we leave it to the district court to
    determine in the first instance, based upon the totality of the circumstances, whether
    or not any or all of Yousif’s statements were sufficiently acts of free will to be
    deemed voluntary, and whether those statements are admissible notwithstanding the
    initial violation of Yousif’s Fourth Amendment rights.

    Conclusion
    For the reasons stated, we vacate the judgment of the district court and remand
    the case to the district court for further proceedings consistent with this opinion.
    MORRIS SHEPPARD ARNOLD, Circuit Judge, dissenting.
    I believe that it is not necessary to decide the difficult question of whether
    stopping Mr. Yousif's vehicle was constitutional, because it is wrong to conclude, as
    the court does, that the district court clearly erred in finding that Mr. Yousif's consent
    to the search of his vehicle was voluntary. If we had the power to review the record
    independently, so that we could arrive at a de novo conclusion on the matter of
    voluntariness, I might well be of the view that the motion to suppress was improperly
    denied. But that of course is not our role. We are to decide whether, after examining
    the record, we are "left with the definite and firm conviction that a mistake has been
    committed," United States v. United States Gypsum Co., 
    333 U.S. 364
    , 395 (1948).
    In this case, the district court heard testimony from the principals involved, and
    it was that court's responsibility in the first instance to decide whether Mr. Yousif's
    will had been overborne when he consented to the search. See Schneckloth v.
    Bustamonte, 
    412 U.S. 218
    , 225-26, 248-49 (1973). In other words, the district court
    had to determine what Mr. Yousif's state of mind was at a certain time, and it will be
    a rare case when an objective observer could say that that determination, whichever
    way it went, was clearly erroneous. The instant case has a great deal in common with
    cases in which a court must determine whether a particular person was motivated by
    some kind of animus when he or she committed an act, and we know that such
    findings are "peculiarly within a trial judge's province." Wainwright v. Witt, 
    469 U.S. 412
    , 428 (1985).
    -18-
    Certainly there are facts in the record here that support the district court's
    conclusion, among the most prominent of which is that Mr. Yousif did not revoke his
    consent when the officer explained that a search could not legally proceed without
    consent or probable cause to believe that evidence of a crime would be uncovered.
    In any event, in the circumstances I cannot say that after examining this record I am
    left with a conviction that the district court's factual finding was clearly wrong.
    Mr. Yousif argues that even if his consent to the search of his vehicle was
    voluntarily given, the law nevertheless requires suppression of the evidence because
    his consent was not so distinct from the unconstitutional stop as to purge the taint of
    the original illegality. As the court recognizes, Wong Sun itself established the
    principle that evidence that would not have been uncovered but for an
    unconstitutional act is admissible if its discovery is fairly attributable to some other
    event that acts as a kind of intervening, independent cause of the discovery. See
    Wong Sun v. United States, 
    371 U.S. 471
    , 487-88 (1963).
    Some of our cases seem to proceed on the principle that a voluntary consent to
    a search ipso facto amounts to an intervening event that renders evidence admissible,
    even though the evidence would have not been discovered but for an illegal act of
    some kind. See, e.g., United States v. Green, 
    275 F.3d 694
    , 700 (8th Cir. 2001);
    United States v. Beason, 
    220 F.3d 964
    , 967 (2000). Mr. Yousif criticizes these cases
    on the ground that they conflate two separate issues, namely, the voluntariness of the
    consent and the severability of that consent from the initial illegality. In other words,
    he says, a good argument can be made that even a voluntary consent to search will not
    always be a sufficiently independent act to render seized evidence admissible.
    In any event, our more expansive discussions of the matter do assume that
    cases like the present one involve two distinct issues, namely, whether the consent to
    search was voluntary, and, if so, whether that consent was given in circumstances that
    render it an independent, lawful cause of the discovery of the relevant evidence. See,
    -19-
    e.g., United States v. Kreisel, 
    210 F.3d 868
    , 869-70 (8th Cir. 2000), cert. denied,
    
    531 U.S. 916
    (2000); United States v. Ramos, 
    42 F.3d 1160
    , 1164 (8th Cir. 1994),
    cert. denied, 
    514 U.S. 1134
    (1995). Whatever approach one takes, however, the
    significant fact (as the district court recognized) is that we have never held that
    incriminating evidence must be suppressed as the fruit of the poisonous tree when a
    voluntary consent to search has intervened between an illegal stop and the discovery
    of that evidence. There is nothing distinctive about the present case that would serve
    to remove it from the usual rule. The court's holding therefore runs contrary to all of
    our precedents.
    In sum, the evidence was admissible against Mr. Yousif even if the stop of his
    vehicle violated the fourth amendment. I would affirm the judgment of the district
    court.
    I therefore respectfully dissent.
    A true copy.
