This is a direct appeal of the criminal conviction of Tommie Childs, who was charged in a one-count indictment with possession of cocaine with intent to distribute in violation of 21 U.S.C. § 841(a)(1). Following a jury trial, Childs was found guilty and sentenced to 120 months imprisonment followed by eight years of supervised release. He now appeals the district court’s order denying his motion to suppress.
I.
Peoria police officer James Chiola first encountered Childs when he responded to a dispatch call regarding a confrontation between two men over a hit and run accident. He arrested Childs on an outstanding arrest warrant; he also found marijuana in Childs’ pocket and charged him with drug possession. At that time, Chiola noticed that the car Childs was driving had a broken windshield, and he told him to get it repaired because he thought it “materially impaired the driver’s view” in violation of 625 ILCS 5/12-503(e) of the Illinois Vehicle Code. Three days later, Chiola spotted the same car, with the windshield still broken, and stopped the car for that reason. He found Childs in the passenger seat and, while Chiola’s partner questioned the driver about the cracked windshield, Chiola proceeded to Childs’ side of the car. Chiola testified that Childs was visibly nervous: he would not look at him, he kept his *562 head down when speaking and he spoke in a low tone of voice. Chiola asked Childs whether he had any marijuana in his possession and later asked if he could search him. Childs consented. As Childs stepped out of the car, he removed a cigarette pack from his pocket and placed it on the seat. As it lay there, the pack opened up, revealing a plastic bag with what appeared to be crack cocaine inside. Chiola arrested Childs for possession.
At trial, Childs argued that the contents of the cigarette pack should be suppressed. During the suppression hearing, he testified that Chiola had not instructed him to fix the windshield when he arrested him three days earlier, that no one spoke to the driver after the stop in question and that he did not leave the cigarette pack on the car seat when he stepped out of the car. The court ruled that the broken windshield provided a reasonable basis for the stop. The court further determined that Chiola’s testimony that Childs removed the cigarette pack from his pocket was more credible than Childs’ conflicting testimony. That ended the matter, because once Childs consented to the search, anything he removed from his pocket prior to the search was fair game.
II.
The sole issue presented for review is whether the district court erred in denying Childs’ motion to suppress. When reviewing the denial of a motion to suppress, our standard of review for the district court’s findings of fact is clear error.
See United States v. Faison,
A.
Childs first challenges the denial of his motion to suppress on the grounds that Chiola had insufficient probable cause to stop the vehicle in the first place. We review a district court’s probable cause determination de novo, while we defer to subsidiary findings of historical fact unless they are clearly erroneous.
Ornelas,
To support his contention, Childs first points to the district court’s state
*563
ments that the probable cause question was a close call. Judge Mihm’s comments were in apparent reaction to the government’s failure to produce much evidence in support of Chiola’s probable cause determination. Thus, Chiola never sat in the driver’s seat to discern whether the crack in the windshield actually obstructed the driver’s view, nor did he photograph the damaged windshield. The evidence presented by the prosecution was indeed scanty, and the district court concluded that it was “not in a position to say that [the crack in the windshield] materially obstructed the driver’s view.” Of course, whether the driver is actually in violation of a law is irrelevant to a probable cause determination “so long as the circumstances confronting a police officer support the reasonable belief that a driver has committed even a minor traffic offense, the officer has probable cause to stop the driver.”
Cashman,
For the purposes of probable cause analysis, we are not concerned with the precise length or position of the crack. The propriety of the traffic stop does not depend, in other words, on whether [the defendant] was actually guilty of committing a traffic offense by driving a vehicle with an excessively cracked windshield. The pertinent question instead is whether it was reasonable for [the police officer] to believe that the windshield was cracked to an impermissible degree.
Cashman,
Childs notes that in a similar case photographic evidence revealing the size and location of the windshield crack was presented to support a finding that there was probable cause.
See Cashman,
B.
Childs next argues that, when Chiola questioned him about drugs, he exceeded the scope of the investigation in violation of the Fourth Amendment. Because traffic stops are considered seizures, they are governed by the principles articulated by the Supreme Court in
Terry v. Ohio,
Childs argues that, because the traffic stop was for the cracked windshield, and because the only other obvious violation was failure to fasten a seatbelt, questioning Childs about drug possession was outside the scope of the stop. A traffic stop must be reasonably related in scope to the circumstances that justified the initiation of the stop.
See United States v. Green,
At the suppression hearing, Chiola explained his basis for questioning Childs about drugs, as well as the reasoning behind his request to search him. He said he took into account Childs’ nervous demeanor, his failure to make eye contract and his low tone of voice, as well as the fact that he knew about Childs’ prior drug violations — including one just three days earlier. We hold that these factors do not rise to the level of reasonable suspicion.
First, when a police officer questions someone during a routine traffic stop, inquiries falling outside the scope of the detention constitute unlawful seizure.
1
This is because both the duration and the scope of a seizure (such as a traffic stop) must be restricted to that necessary to fulfill the seizure’s purpose.
Florida v. Royer,
The reason is that these two factors alone tell us little about whether suspicion is reasonable. The defendant’s criminal record (even, as here, of very recent vintage) is an aspect of his status, which is unalterable, whether he is committing a crime at the time his vehicle is stopped or not. Whether he possessed drugs three days ago or one year ago, or never, cannot reasonably show that he possesses drugs today — not unless some other factor related to the defendant’s circumstances
today
can buttress his criminal past. Similarly, nervousness is a natural reaction that a seasoned criminal might have every time he is confronted by a police officer — particularly when it is the same police officer who arrested him three days before. It is true that a criminal record plus one or two other factors has been deemed in some cases sufficient for reasonable suspicion, but the second factor in those cases has
*566
often involved more tangible evidence, or at least evidence more related to whether the criminal is committing a crime at that particular moment. For example, we have found that status as a “dangerous” convicted felon plus the presence of a gun in view on the floor of the car could create reasonable suspicion.
Valance,
As our reasoning in
Valance
demonstrates, reasonable suspicion findings are often easier to swallow when the safety of the officer is at stake. In that case, a “dangerous” felon possessed what appeared to be a gun in his car. In other cases, findings of reasonable suspicion based on criminal history in addition to marginal supplementary evidence appear to be grounded in the concern for the officers’ safety, and the analysis more forgiving. For example, presence in a “high crime corridor” plus a rental car contract signed by a party not in the car plus a criminal record established reasonable suspicion, the Eleventh Circuit said — or at least reasonable safety concerns.
United States v. Purcell,
Indeed, in a case in which there were numerous articulable factors establishing suspicion, we still qualified our finding that reasonable suspicion existed sufficient to conduct a criminal record inquiry during a traffic stop: “Significant to our conclusion are the facts that the request took only five extra minutes
and involved no additional questioning,
no action on the part of the defendants, and no request or wait for a canine unit.”
Finke,
We therefore find that, during the routine traffic stop, Childs was asked questions well beyond the scope of an investigation related to the purpose of the stop.
C.
Childs’ final argument, challenging the voluntariness of his consent, is of importance only because we have found that Chiola exceeded the scope of the stop when inquiring about drugs. The government asserts that Childs has also forfeited the consent argument on appeal, because he did not raise this argument before the district court. Indeed, he conceded consent (though not its voluntariness) in the district court. Therefore, we will review this conclusion of the district court for plain error.
See Clarke,
The question whether one’s consent to search was voluntary must be determined in light of the “totality of the circumstances.”
Schneckloth v. Bustamonte,
the age, education, and intelligence of the individual providing consent; whether he was advised of his rights; how long he was detained prior to giving consent; whether he immediately consented, or whether the police officers made repeated requests for consent; the existence or absence of physical coercion; and whether the individual was -in custody.
Valance,
Even if the drug question was permissible, Childs argues that the consent was not knowing and voluntary because Chiola had indicated that he could conduct a search based on the seatbelt violation. The exchange between Childs and Chiola, as recounted in Childs’ testimony, appears to imply that possibility:
I said, “What would you search me for?” He said, “Because you ain’t got no seat belt on.” I said, “No, you ain’t going to find nothing on me.” He said, “Are you sure of that?” I said, “Yeah. You can search me. That’s when he asked me to get out of the car.”
This exchange might raise questions because it may signal Childs’ belief that the search could have been conducted without his consent, and this could undermine the knowing and voluntary nature of the consent. However — absent the prior improper questioning — the district court’s finding that there was voluntary consent would not rise to the level of plain error, particularly considering the fact that Childs testified in the court below that he consented. We will reverse for plain error only in quite exceptional circumstances.
Linwood,
But that does not end our inquiry. When, as here, consent was obtained following illegal questioning, the inquiry into voluntariness becomes more searching:
[T]o determine whether the acquisition of evidence pursuant to consent is purged of the taint of an antecedent illegal seizure, we place a “heavy burden” on the government and look to “(1) the temporal proximity of the illegal detention [to the defendants’ consent]; (2) the presence of intervening factors between the two events; and (3) the circumstances surrounding, and the nature of, the official misconduct.”
Jerez,
III.
For the foregoing reasons, we AFFIRM the judgment of the district court as to probable cause; we REVERSE the district court’s conclusion that Chiola’s questioning did not violate Childs’ Fourth Amendment rights; and we REMAND to *568 the district court for consideration of the question whether Childs’ consent was nonetheless voluntary.
Notes
. So far as this court can determine, only the Fifth Circuit disagrees with this proposition.
See United States v. Shabazz,
. We note that here we have not only criminal history, but very recent criminal history. Nonetheless, we decline to give this factor decisive weight in the reasonable suspicion analysis. Our precedent does not appear to demand making a distinction between recent and more remote history of criminal acts. While in
Feliciano
we indicated that knowledge of recent criminal conduct was "a permissible component of the articulable suspicion required for a
Terry
stop,”
