Opinion by Judge WALLACE; Dissent by Judge PAEZ.
WALLACE, Senior Circuit Judge:
The government appeals from the district court's order suppressing evidence obtained from the search of Turvin's vehicle. While Turvin was waiting for a police officer to issue a traffic citation, the officer questioned Turvin about methamphetamine and obtained Turvin's consent to search his vehicle for contraband. The district court held that the officer's questions about methamphetamine and request to conduct a search, unsupported by reasonable suspicion, turned an initially reasonable detention into an unconstitutional one and rendered Turvin's consent involuntary. We have jurisdiction pursuant to 18 U.S.C. § 3731 and we reverse.

I.
On the evening of November 20, 2005, Alaska State Trooper Christensen stopped a white pickup truck based on the truck's unusually loud exhaust, rapid acceleration around a turn involving minor skidding, and driving six miles over the speed limit in snowy conditions. When he approached the truck, which had entered a gas station parking lot, the Trooper observed that neither occupant appeared to be wearing a seatbelt and that the truck's registration was expired. He asked the occupants for identification; the driver was Sean T. Turvin and the occupant was Corina L. Cunningham. The Trooper talked to them for three or four minutes about the violations he had observed and then returned to his police vehicle, where he radioed headquarters to conduct a warrant and license check. The response informed him that Turvin's driver's license was current and valid.
About ten minutes after the stop began, while Christensen sat in his vehicle writing out traffic citations, Trooper Powell arrived at the scene. Powell had heard Christensen on the police radio and recognized Turvin's name because he knew that a "rolling methamphetamine laboratory" had been found in Turvin's vehicle following a traffic stop earlier that year.
When Powell arrived, he recognized Turvin and Turvin's truck, and informed Christensen about the prior incident. Christensen then stopped writing out the traffic citations, turned on his tape recorder, and stepped out to speak with Turvin, who was still in his truck. Powell positioned himself at the rear of Turvin's truck to assist if needed.
Upon approaching the truck, Christensen told Turvin that he knew about the rolling methamphetamine laboratory, which Turvin acknowledged. Christensen then observed something in plain view behind *1099 Turvin's seat, which Turvin identified as a speaker box. Christensen then asked Turvin if he would mind if Christensen searched his vehicle because the speaker box, Christensen said, "look[ed] very odd." The conversation was calm and relaxed, and Turvin consented to the search without equivocation.
The search ultimately yielded a sawed-off shotgun 1 inches below the minimum legal length and a small cup containing packages of a crystal substance determined by field test to be methamphetamine. Turvin was placed in custody when the methamphetamine packages were discovered.
Turvin and Cunningham were cited for not wearing seatbelts, and Turvin was cited for his truck's loud exhaust. Cunningham was arrested based on her proximity to the drugs found in the cup. A search of Cunningham revealed $773 in cash. Later, when police examined the cash at the police station, they found mixed in among the bills a plastic bag containing a substance suspected to be methamphetamine.
Turvin and Cunningham were indicted for conspiracy to traffic methamphetamine and possession with intent to distribute five grams or more of methamphetamine. Turvin was also indicted for possession of a prohibited firearm. Turvin filed a motion to suppress, which Cunningham joined, arguing that "the police had no reasonable suspicion for the prolonged detention," and that Turvin's consent to the search of his truck was involuntary.
The district court granted Turvin's motion to suppress, adopting the magistrate judge's (MJ) recommendation that, though the initial traffic stop was lawful and based on probable cause that a traffic violation had occurred, Christensen "exceeded the scope of the traffic stop" by "investigat[ing] into suspected drug activities beyond the scope of the traffic stop during the time that Turvin was not free to leave." The MJ and district judge agreed that this investigation violated Turvin's Fourth Amendment rights as explained by us in United States v. Chavez-Valenzuela, 268 F.3d 719 (9th Cir.2001). Turvin's consent to the search, the MJ reasoned, did not render the search lawful because it was obtained during "an extended and an unlawful detention arising from a traffic stop." The district judge denied the government's motion for reconsideration and the government timely appealed.

II.
We review for clear error the district court's underlying findings of fact and de novo the district court's ruling on a motion to suppress. United States v. Miranda-Guerena, 445 F.3d 1233, 1236 (9th Cir.2006). The only disputed issue on appeal is whether Christensen violated Turvin's and Cunningham's Fourth Amendment rights by asking questions unrelated to the purpose of the stop that unreasonably extended the duration of the initially lawful traffic stop.

A.
Our analysis of the district court decision is based primarily on our recent and on-point decision in United States v. Mendez, 476 F.3d 1077 (9th Cir.2007), which we decided after the district court's final ruling. In Mendez, we rejected a Fourth Amendment claim despite the fact that police officers in that case had, without reasonable suspicion, asked Mendez questions unrelated to the purpose of an initially lawful traffic stop. Id. at 1081. In so deciding, we acknowledged that the Supreme Court had overruled those portions of Chavez-Valenzuela (the case upon which the district court's decision was based) that required police officers to have reasonable suspicion to ask questions beyond *1100 the scope of a traffic stop. Id. at 1080.
In Mendez, Detectives Jaensson and Bracke had stopped Mendez because his car did not have a license plate or temporary registration tag. Id. at 1078. While Bracke conducted a records check in the patrol car, Jaensson waited at the curb with Mendez and asked him several questions unrelated to his license plate or vehicle registration. Id. at 1078-79. Once Bracke completed the records check, he started back toward the curb to inform Mendez that his temporary registration plate had expired; en route, he overheard Mendez telling Jaensson that he was "trying to get away from the gang life" and that he had spent time in an Illinois prison. Id. at 1079. As he approached the curb, Bracke asked Mendez why he had been imprisoned; Mendez replied that he had been convicted of a weapons violation. Id. Bracke then asked whether Mendez had any weapons in the car and Mendez eventually admitted to having a firearm in the driver's door handle. Id. The officers arrested Mendez and searched the vehicle, finding a loaded, small caliber, semi-automatic pistol. Id. Mendez moved to suppress the handgun, but the district court denied his motion. Id.
Mendez pled guilty but preserved the right to appeal from the district court's denial of his motion, arguing that the officers lacked reasonable suspicion to interrogate him about matters beyond the purpose of the stop and that the officers unreasonably prolonged the stop. Id. We rejected Mendez's arguments, relying on the Supreme Court's decision in Muehler v. Mena, 544 U.S. 93, 125 S.Ct. 1465, 161 L.Ed.2d 299 (2005), which held that "mere police questioning does not constitute a seizure" and thus no reasonable suspicion is required to justify questioning that does not prolong an initially lawful stop. Mendez, 476 F.3d at 1080, quoting Muehler, 544 U.S. at 101, 125 S.Ct. 1465 (internal quotation marks omitted). We concluded that "the officers' questioning of Mendez did not extend the duration of a lawful stop" and so "the expanded questioning need not have been supported by separate reasonable suspicion." Id. at 1081.
The Mendez and Muehler reasoning is persuasive in this appeal, and we reject Turvin's and the dissent's reliance on Chavez-Valenzuela; contrary to the dissent's assertion, none of the aspects of Chavez-Valenzuela that are relevant to this appeal survive Muehler.
We disagree with the dissent's characterization of the primary holding in Chavez-Valenzuela. The dissent asserts the primary holding was "that an officer cannot ask questions that extend the duration of a traffic stop beyond its initial purpose without having reasonable suspicion for doing so." Diss. Op. at 1107. The dissent errs as the issue before this court in Chavez-Valenzuela was whether nervousness alone provided the reasonable suspicion required (at the time) to justify an officer's continued detention of a suspect after he had satisfied the purpose of the stop. 268 F.3d at 726. The question of whether reasonable suspicion was necessary to justify questioning that prolonged the duration of the stop was simply not relevant (and certainly not addressed) in Chavez-Valenzuela, because at the time it was decided any questioning unrelated to the purpose of the stop, regardless of its effect on the duration of the stop, needed to be supported by reasonable suspicion. See id. at 724. That underlying assumption is no longer good law. See Mendez, 476 F.3d at 1080 ("To the extent that Chavez-Valenzuela . . . hold[s] that such questioning must be supported by reasonable suspicion, [it has] been overruled by Muehler.") Mendez is the law on police questioning *1101 during a traffic stop, and it is Mendez that we must apply to the facts of this case.

B.
However, we must now address a factual distinction between this case and Mendez that has not yet been resolved by our post-Muehler cases. As we pointed out in Mendez, "the stop was not unnecessarily prolonged." Id. at 1079. Jaensson's questioning occurred while Bracke was checking on Mendez's identification, so "the stop would, in any event, have lasted until after the check had been completed." Id. at 1080. Once the records check was complete, Bracke, who had overheard Mendez's comments about gang membership and jail time, "immediately asked his two questions." Id. We also pointed out that from the time of the stop up to the arrest was only eight minutes. Id.
Turvin contends that in this case, the stop was unnecessarily prolonged. The MJ did not specifically address this point, determining that the questions were unconstitutional merely because they were outside the scope of the stop, a conclusion now clearly foreclosed by Mendez. After a motion for reconsideration, however, the MJ did state in his final report that "the traffic stop . . . was extended or prolonged because of the comments by late arriving Trooper Powell. . . . Although Trooper Christ[e]nsen had been writing traffic tickets . . . he stopped his ticket-issuing process and used a tape recorder solely for the purpose of asking Turvin about drugs and for [ ] consent to search his vehicle."
The question, then, is this: does the fact that Christensen paused his ticket-writing process to ask a few questions unrelated to the purpose of the traffic stop, thereby prolonging, for at least a few moments, the duration of that otherwise legal stop, turn the initially lawful stop into an unlawful detention? That is, based on the factual circumstances underlying this appeal, did Christensen's brief pause unreasonably prolong the traffic stop and thus violate Turvin's Fourth Amendment right to be free from an unreasonable seizure?
We have never considered whether questioning unrelated to the purpose of the traffic stop and separate from the ticket-writing process that prolongs the duration of the stop may nonetheless be reasonable under Muehler's Fourth Amendment analysis. Nor have other circuits squarely addressed this factual situation. However, the Supreme Court's teaching that "the touchstone of the Fourth Amendment is reasonableness," Florida v. Jimeno, 500 U.S. 248, 250, 111 S.Ct. 1801, 114 L.Ed.2d 297 (1991), gives us important guidance. The Court has emphasized that a fact-specific reasonableness inquiry is appropriate for Fourth Amendment questions. See Ohio v. Robinette, 519 U.S. 33, 39, 117 S.Ct. 417, 136 L.Ed.2d 347 (1996). Therefore, in the present case, we must examine the "totality of the circumstances" surrounding the stop, and determine whether Christensen's conduct was reasonable. Id.
In Mendez, we identified the overall length of the stop, observing that the eight-minute stop was not beyond the time normally required to issue a citation. 476 F.3d at 1079-80. We also pointed out that Jaensson and Bracke did not intentionally delay the stop but diligently pursued their investigation into the purpose of the stop. Id. at 1080.
As in Mendez, the circumstances surrounding the brief pause here were reasonable. The total duration of the stop up to the point at which Turvin consented to the search was, according to Christensen's uncontested testimony, about fourteen minutes. This is no longer than an ordinary traffic stop could reasonably take, and we do not agree with the dissent that *1102 evidentiary findings are necessary to demonstrate the sensible observation that fourteen minutes is not unreasonably long for a traffic stop. Of that time, it took Christensen perhaps four minutes to speak with Powell and then to walk to Turvin's vehicle and ask him about the rolling methamphetamine laboratory and for consent to search. This was reasonable for him to do based on Powell's arrival and information about a rolling methamphetamine laboratory involving the same vehicle and the same person.
Moreover, that Christensen observed the speaker box prior to requesting consent to search buttresses the conclusion that his request was reasonable under the circumstances. Christensen knew of a prior rolling methamphetamine laboratory, which could have been contained in something like the speaker box, justifying further inquiry. The speaker box observation is significant. The MJ's initial findings of fact indicated that Christensen did not see the box behind Turvin's seat until after he sought consent to search. We agree with the government that this finding is clearly erroneous; the audio recordings of the stop show that Christensen did observe the box before requesting consent to search. This fact is relevant in establishing the circumstances in which Christensen asked for consent to search. Just as it was reasonable in Mendez for officers to ask questions based on information learned during the course of the stop, Christensen's question and request to search were reasonable based on facts learned and observations made after he stopped Turvin.
Sister circuits have adopted the same analysis: brief pauses to ask questions during traffic stops, even if those questions are unrelated to the purpose of the stop, may be permissible under Muehler. The Tenth Circuit held that questioning that does not "appreciably" extend the duration of a traffic stop is reasonable, see United States v. Stewart, 473 F.3d 1265, 1269 (10th Cir.2007), United States v. Alcaraz-Arellano, 441 F.3d 1252, 1259 (10th Cir. 2006). The Tenth Circuit has declined to "make a time and motion study of traffic stops" in order to determine the precise effect that questioning has on the duration of a stop, reasoning instead that courts must "consider the detention as a whole." United States v. Patterson, 472 F.3d 767, 776 (10th Cir.2006).
The Eighth Circuit has similarly held that a traffic stop based on probable cause for driving at an excessive speed was not made unreasonable when an officer "ask[ed] three brief questions related to possible drug trafficking amidst his other traffic related inquiries and tasks." United States v. Olivera-Mendez, 484 F.3d 505, 511 (8th Cir.2007). (We do not pass upon that court's adoption of a de minimis exception justifying brief questions.)
Indeed, officers are not required to move at top speed when executing a lawful traffic stop. As the Eleventh Circuit has stated,
A traffic stop for speeding can doubtlessly last long enough for the police to ask questions about the reasons for speeding and to conduct a variety of checks about licenses, registration, insurance and so on. We underline that the police are not constitutionally required to move at top speed or as fast as possible. For the police to be vigilant about crimes is, at least broadly speaking, a good thing. And at a traffic stop, the police can occasionally pause for a moment to take a breath, to think about what they have seen and heard, and to ask a question or so. The police are authorized to detain traffic violators for a reasonable amount of time.
United States v. Hernandez, 418 F.3d 1206, 1212 n. 7 (11th Cir.2005) (internal *1103 citation omitted); see also United States v. Sharpe, 470 U.S. 675, 686, 105 S.Ct. 1568, 84 L.Ed.2d 605 (1985) (holding that a detention was not unreasonable where officers, though slowed down, were diligent in their investigation).
This analysis applies with particular force where, like here, officers have probable cause to know of a traffic violation. The Seventh Circuit, in a pre-Muehler decision, persuasively reasoned that where probable cause of a traffic violation supports a stop, a driver does not
ha[ve] a right to be released the instant the steps to check license, registration, and outstanding warrants, and to write a ticket, ha[ve] been completed. It is therefore not necessary to determine whether the officers' conduct added a minute or so to the minimum time in which these steps could have been accomplished. . . . What the Constitution requires is that the entire process remain reasonable. Questions that hold potential for detecting crime, yet create little or no inconvenience, do not turn reasonable detention into unreasonable detention.
United States v. Childs, 277 F.3d 947, 953-54 (7th Cir.2002) (en banc). We agree with this reasoning and result.
Christensen's brief pause in the ticket-writing process was reasonable, as was the duration of the detention until consent was given. We will not accept a bright-line rule that questions are unreasonable if the officer pauses in the ticket-writing process in order to ask them. The Supreme Court has "consistently eschewed bright-line rules [in the Fourth Amendment context], instead emphasizing the fact-specific nature of the reasonableness inquiry." Robinette, 519 U.S. at 39, 117 S.Ct. 417. It is true that in Mendez, the officers managed to ticket and question detained drivers simultaneously. See Mendez, 476 F.3d at 1078-79. That has been true in situations considered by other circuits as well. See, e.g., United States v. Soriano-Jarquin, 492 F.3d 495, 501 (4th Cir.2007) ("In this case, [the Trooper's] request for identification did not prolong the stop, as it occurred while the police trainee checked the driver's license and registration and prepared his citations"). It does not follow, however, that those are the only circumstances in which it is reasonable to ask unrelated questions. The Supreme Court does not set such a narrow rule, and neither do we. An officer who asks questions while physically writing a ticket will likely be slowed down just as an officer who briefly pauses to do so. There is no principled reason why the second situation is unconstitutional but not the first.
The present case illustrates the irrationality of the distinction Turvin and the dissent offer. Under their proposed brightline rule, Christensen's questions may have been permissible in a number of scenarios materially indistinguishable from what happened here: if Christensen had asked about drugs when he originally stopped Turvin, or as he was handing the ticket to Turvin, or if Christensen had asked Powell to continue writing the ticket while he approached Turvin, or if Powell had asked the questions while Christensen wrote the ticket. Permitting those scenarios but not the reasonable actions that Christensen chose to take would draw an arbitrary and unjustified line between constitutional and unconstitutional conduct. Rather than bright-line simplification, the Constitution requires a reasonableness analysis.

III.
We hold that Mendez's conclusion that officers do not need reasonable suspicion to ask questions unrelated to the purpose of an initially lawful stop applies here because Christensen's question and request *1104 for consent to search did not unreasonably prolong the duration of the stop. Because we decide on this basis, we do not reach the issue of whether reasonable suspicion supported Christensen's questioning.
As the stop was at all times a lawful detention, Turvin's voluntary consent rendered Christensen's search legal. See United States v. Torres-Sanchez, 83 F.3d 1123, 1129 (9th Cir.1996). Therefore, the evidence obtained as a result of that search is admissible and the district court's order to suppress is REVERSED.
PAEZ, Circuit Judge, dissenting:
Because I do not believe that reasonable suspicion supported Trooper Christensen's decision to prolong his traffic stop of Turvin, I would affirm the district court's order granting Turvin's motion to suppress. I therefore respectfully dissent.
First, I agree with the majority that after the Supreme Court's decision in Muehler v. Mena, 544 U.S. 93, 125 S.Ct. 1465, 161 L.Ed.2d 299 (2005), our analysis of the Fourth Amendment issues in this case must be guided by our recent decision in United States v. Mendez, 476 F.3d 1077 (9th Cir.2007). There, we recognized that in Muehler, the Court decided that "mere police questioning does not constitute a seizure unless it prolongs the detention of the individual, and, thus, no reasonable suspicion is required to justify questioning that does not prolong the stop." Mendez, 476 F.3d at 1080 (internal quotation marks omitted). Although Muehler did not arise in the context of a traffic stop, we further recognized that the Court's reasoning applied to such an encounter. Id.
In several cases prior to Muehler, we had held that during the course of a traffic stop "[a]n officer must initially restrict the questions he asks . . . to those that are reasonably related to the justification for the stop." United States v. Chavez-Valenzuela, 268 F.3d 719, 724 (9th Cir.2001) (citing United States v. Perez, 37 F.3d 510, 513 (9th Cir.1994)). See also United States v. Murillo, 255 F.3d 1169, 1174 (9th Cir.2001). We had emphasized that an officer could expand the scope of questioning "only if he notices particularized, objective factors arousing his suspicion." Chavez-Valenzuela, 268 F.3d at 724 (citation omitted). After Muehler, this line of reasoning could not pass constitutional muster, and we so held in Mendez. We therefore concluded that: "[t]o the extent that Chavez-Valenzuela, Murillo, and Perez hold that such questioning must be supported by separate reasonable suspicion, they have been overruled by Muehler." Mendez, 476 F.3d at 1080. Recognizing this new legal landscape, we rejected Mendez's Fourth Amendment challenge to his arrest, explaining that, "because . . . the officers' questioning did not prolong the stop, we are compelled to hold that the expanded questioning need not have been supported by separate reasonable suspicion." Id. at 1080-81.
Here, to the extent that the district court's suppression ruling relied on the portion of Chavez-Valenzuela that was overruled by Mendez, it was incorrect. As the majority recognizes, however, this was not the only basis for the district court's ruling. In the magistrate judge's Final Recommendation Regarding Defendant's Motion to Suppress, he explained:
[As the [Initial] Recommendation concluded the traffic stop of Turvin and his passenger Cunningham was extended or prolonged because of the comments by late arriving Trooper Powell who advised Trooper Christiansen [sic] of a prior police contact with Turvin involving a rolling meth lab. Although Trooper Christiansen [sic] had been writing traffic tickets to Turvin and Christiansen [sic] (for not wearing a seat belt), he stopped his ticket-issuing process and used a tape recorder solely for the purpose *1105 of asking Turvin about drugs and for a consent to search his vehicle. Normally, an officer engaged in a traffic stop will not use a tape recorder. Tr. 25. The magistrate judge reaffirms his finding that the police prolonged the otherwise lawful detention of Turvin and his passenger on grounds for which they did not have reasonable suspicion for doing so.]
I agree with the district court that reasonable suspicion did not exist to prolong the stop of Turvin and his companion. It is clear from Trooper Christensen's testimony that until Trooper Powell arrived on the scene, Christensen did not have any reason to suspect that either Turvin or his companion had been or were engaged in any illegal drug activity.
Christensen had stopped Turvin's truck because of its loud exhaust, rapid acceleration around a corner, minor skidding and speeding. As Christensen approached the truck, he observed that neither occupant appeared to be wearing a seatbelt and the truck's registration was expired. After Christensen conducted a license and warrants check on Turvin, he was informed that Turvin's license was current and valid. Trooper Christensen then decided to issue traffic citations to Turvin and his companion.
About ten minutes after the stop began, while Christensen sat in his vehicle writing out the traffic citations, Trooper Powell arrived at the scene. Powell had heard Christensen on the police radio and recognized Turvin's name, because he knew that a "rolling meth lab" had been found in Turvin's vehicle following a traffic stop earlier in 2005.
When Powell arrived at the scene, he recognized Turvin and his truck and informed Christensen about the prior incident. Christensen then (1) "stopped his ticket-issuing process," (2) turned on the tape recorder in his police vehicle "solely for the purpose of asking Turvin about drugs and for a consent to search his vehicle," and (3) exited his vehicle and returned to Turvin's truck, while Powell positioned himself at the rear of Turvin's vehicle to stand by as backup. At this point, the troopers had not seen anything in the truck to indicate that it might contain methamphetamine or that Turvin and his companion were involved with meth.
After returning to the truck, Christensen told Turvin, who was standing outside his vehicle, that he knew about the rolling meth lab, which Turvin acknowledged. After stating that he could see something behind Turvin's seat, which Turvin said was a speaker box, Christensen asked Turvin if he could search his vehicle. The purpose of seeking Turvin's consent was to search for contraband.
Although the majority faults the magistrate judge for erroneously finding that Christensen asked for consent to search before observing the speaker box, I agree with his determination that whether this observation occurred before or after Christensen asked for consent, is immaterial. What is important in my view is that, when Powell informed Christensen about his prior encounter with Turvin earlier in 2005, Christensen did not just "briefly pause" in writing the traffic citations so that he could ask Turvin for consent to search his truck. Rather, Christensen completely stopped writing the citations and decided to embark upon a drug investigation. Indeed, he turned on his tape recorder for the purpose of asking Turvin about drugs and for consent to search his vehicle. Because, as the magistrate judge correctly found, this new endeavor prolonged the length of the stop, Christensen needed reasonable suspicion to do so.
Here, reasonable suspicion did not exist. Reasonable suspicion requires a "particularized and objective basis for suspecting *1106 the person stopped of criminal activity." United States v. Tiong, 224 F.3d 1136, 1140 (9th Cir.2000) (internal quotation marks omitted). There was nothing about the traffic infractions or Turvin's conduct after the stop that provided an objective basis for a reasonable officer to suspect that illegal drug activity was afoot. Moreover, Christensen did not immediately see anything in the truck that aroused his suspicion. It was not until Powell arrived at the scene with information about his prior contact with Turvin that Christensen even considered inquiring about illegal drug activity. This new information that centered on Turvin's prior criminal record, by itself, was insufficient to support reasonable suspicion. Burrell v. McIlroy, 464 F.3d 853, 858 n. 3 (9th Cir.2006) ("Although a prior criminal history cannot alone establish reasonable suspicion or probable cause to support a detention or an arrest, it is permissible to consider such a fact as part of the total calculus of information in these determinations."). See also United States v. Chamberlin, 644 F.2d 1262, 1265 (9th Cir.1980); United States v. Santos, 403 F.3d 1120, 1132 (10th Cir.2005).
The majority finds it significant that Christensen did not ask for consent until after he observed the speaker box behind Turvin's seat. The majority's emphasis on this observation, however, minimizes Christensen's response to the information provided by Powell. It seems obvious, that, with this new information, Christensen had a hunch that if he were to search the truck he might well find drugs, drug paraphernalia, or even a "rolling meth lab." A hunch, while it might reflect good police intuition, does not amount to reasonable suspicion. See United States v. Thomas, 211 F.3d 1186, 1191 (9th Cir.2000) ("Reasonable suspicion must be based on more than an officer's `inchoate and unparticularized suspicion or `hunch.''" (quoting Terry v. Ohio, 392 U.S. 1, 27, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968))); Chavez-Valenzuela, 268 F.3d at 724 ("Conversely, an inchoate and unparticularized suspicion or `hunch' cannot withstand scrutiny under the Fourth Amendment." (quoting United States v. Sokolow, 490 U.S. 1, 7, 109 S.Ct. 1581, 104 L.Ed.2d 1 (1989))).
In sum, I agree with the district court's determination that reasonable suspicion did not exist to prolong the traffic stop. The majority does not directly address this issue. Maj. Opin. at 1104. ("[W]e do not reach the issue of whether reasonable suspicion supported Christensen's questioning."). Instead, the majority, while invoking a fact-specific Fourth Amendment reasonableness inquiry, concludes that "we must examine the "totality of the circumstances" surrounding the stop, and determine whether Christensen's conduct was reasonable." Maj. Opin. at 1101. Ultimately, the majority holds that "Mendez's conclusion that officers do not need reasonable suspicion to ask questions unrelated to the purpose of an initially lawful stop applies here because Christensen's question and request for consent to search did not unreasonably prolong the duration of the stop." Maj. Opin. at 1103-1104. In the context of this case, this approach can not be sanctioned by Mendez, or Chavez-Valenzuela, or by the district court's findings.
As I read Mendez (and Muehler), when a police officer asks questions that exceed the purposes of a traffic stop, such questioning "does not constitute a seizure unless it prolongs the detention of the individual." Mendez, 476 F.3d at 1080 (emphasis added) (internal quotation marks omitted). When the expanded questioning prolongs the duration of an initially lawful stop, however, such questioning must be supported by reasonable suspicion. Id. Although Mendez overruled portions of Chavez-Valenzuela, id. at 1080, it left intact its primary holding *1107  that an officer cannot ask questions that extend the duration of a traffic stop beyond its initial purpose without having reasonable suspicion for doing so. Chavez-Valenzuela, 268 F.3d at 725-26. Thus, as I have discussed, the critical question here is whether reasonable suspicion existed for the extended stop, and not whether the extended duration was reasonable under all the circumstances.
In support of its holding, the majority points to the information provided by Powell about his prior contact with Turvin, characterizes the interruption in the ticket writing as brief, emphasizes Christensen's observation of the speaker box behind Turvin's seat, and finds that the duration of the stop to the point at which Turvin consented to the search  approximately fourteen minutes  "is no longer than an ordinary traffic stop could reasonably take." Maj. Opin. at ____. There is nothing in the record to support the latter finding. The Government did not present any evidence on this issue, and the district court did not make such a finding. This is a factual determination that is best left to the district court. In any event, because the majority adopts an approach that is inconsistent with Mendez and Chavez-Valenzuela, I am not persuaded by its assessment of Trooper Christensen's conduct.
With the majority's approach, it will take very little for traffic officers to invoke T.V. Detective Columbo's infamous strategy of asking "just one more question." See United States v. Chavez-Valenzuela, 281 F.3d 897, 897-98 n. 1 (9th Cir.2002) (O'Scannlain, J., dissenting from denial of rehearing en banc). So long as there is some basis to briefly prolong a stop, even when the purpose of the stop has ended, there will be no Fourth Amendment violation. Although it does not take much to satisfy the reasonable suspicion standard  particularized objective facts that criminal activity is afoot  the majority's new approach lowers Fourth Amendment protection another notch.
The majority's discussion of cases from several of our sister circuits is not persuasive. In United States v. Stewart, 473 F.3d 1265 (10th Cir.2007), the county sheriff's expanded questioning occurred while the motorist was in the process of retrieving his driver's license, and, as the defendant conceded, the questions did not appreciably prolong the stop. In United States v. Alcaraz-Arellano, 441 F.3d 1252, 1256-58 (10th Cir.2006), the expanded questioning occurred while the officer was gathering and verifying information provided by the driver of the vehicle. Notably, when the officer returned the license to the driver, and then began to ask additional questions, the court determined that the officer prolonged the stop, which could only be justified if the officer had reasonable suspicion. Id. at 1259-60. After considering all of the information that the officer had acquired during the course of the stop, the court held that the officer had reasonable suspicion to further detain the driver. Id.
In United States v. Patterson, 472 F.3d 767, 777 (10th Cir.2006), Patterson alleged that the trooper prolonged the detention while obtaining his documents and conversing with him as the trooper waited for verification of Patterson's license and vehicle registration. He argued that the trooper deliberately extended the time necessary to complete the stop so that another trooper could arrive with a drug detection dog to inspect Patterson's vehicle, which took place approximately ten minutes into the stop. Id. at 773, 777. In evaluating the reasonableness of the stop from the initial detention to the issuance of the traffic ticket, the court held that the trooper did not unreasonably prolong the stop and relied upon the fact that Patterson did the majority of the talking. Id. at *1108 777. As the trooper finished writing a warning ticket, a drug detection dog alerted to a scent on the vehicle. Id. at 773. After the dog alerted several more times, the trooper searched the vehicle and found illegal drugs in a hidden compartment. Id. The dog alert provided reasonable suspicion for the troopers to prolong their detention of Patterson from the alert to the arrest. Id. at 776.
In Patterson, the court disagreed with the defendant's argument that the trooper prolonged the stop by taking too long to complete those actions necessary to issue a traffic ticket; the court further held that the shift in focus to a drug investigation did prolong the stop but was supported by reasonable suspicion. Id. at 777-78. Here, Christensen did not extend the detention of Turvin while he obtained information from Turvin immediately after the stop or while he waited for the warrants check and verification of Turvin's license. Nor do the facts suggest that Turvin was overly talkative. Only after Powell arrived on the scene, did Christensen stop writing the traffic citations and refocus the stop into a drug investigation, thus prolonging it. He did so without reasonable suspicion.
Without much explanation or analysis, the majority is persuaded by and adopts the Seventh Circuit's approach in United States v. Childs, 277 F.3d 947 (7th Cir. 2002) (en banc). There, the court held "that where a seizure of a person is based on probable cause to believe that a traffic violation was committed, an officer does not violate the Fourth Amendment by asking a few questions about matters unrelated to the traffic violation, even if this conversation briefly extends the length of the detention." United States v. Olivera-Mendez, 484 F.3d 505, 510 (8th Cir.2007). Several other circuits, the Eighth in Olivera-Mendez, id. at 511, and the Sixth in United States v. Burton, 334 F.3d 514, 518-19 (6th Cir.2003), have also adopted the Seventh Circuit's reasoning in Childs.
In our circuit, however, the majority does not write on a clean slate. As I read Chavez-Valenzuela and Mendez, when an officer prolongs a traffic stop with expansive questioning, the extended duration must be supported by reasonable suspicion. Although we concluded that probable cause existed to stop Chavez-Valenzuela for speeding, we proceeded to examine whether the extended detention was supported by reasonable suspicion. Chavez-Valenzuela, 268 F.3d at 725-727. In Mendez, the validity of the initial stop was not disputed. Nonetheless, we clearly held that questioning that extends the duration of a stop must be supported by reasonable suspicion. See Mendez, 476 F.3d at 1080. That holding is consistent with the part of Chavez-Valenzuela that remains good law. In my view, the majority's approach to this important Fourth Amendment issue is at odds with Chavez-Valenzuela and with our bottom line holding in Mendez.
For all the above reasons, I would affirm the district court's suppression ruling. I therefore respectfully dissent.
