Plain tiff-appellant, Charles Walraven, entered a conditional plea of guilty under Fed.R.Crim.P. 11(a)(2) in the federal district court to possession with intent to distribute cocaine as proscribed by 21 U.S.C. § 841(a)(1). Walraven’s plea was conditioned upon his right to bring this apрeal challenging the district court’s denial of his motion to suppress evidence of two kilograms of cocaine which Wyoming state officials obtained in a warrantless search of his vehicle.
United States v. Pitchford,
I.
Following an evidentiary hearing on Wal-raven’s motion to supprеss, the district court entered thorough findings of fact into the record as required by Fed.R. Crim.P. 12(e). Based on its view of the testimony and the various witnesses' credibility, the court found that the government had met its burden of proving the constitutionality of its actions.
See United States v. Carreon,
The district court’s factual findings, which harbor ample support in the record, may be briefly summarized: On the morning of March 26, 1988, Deputy Robert De-bree of the Albаny County, Wyoming, Sheriff’s Department, observed two men in a 1983 brown Cadillac bearing the Tennessee license plate CYR 490 traveling east on 1-80 near Laramie. Debree, a seven year veteran of law enforcement who routinely ran license and registration checks on out-of-state vehicles, decided to do so on the Cadillac. A license check with the FBI’s National Crime Information Center (NCIC) proved negative. The registration check, however, indicated that the plate number belonged to a 1988 Toyota. Debree activated his overhead lights in an attempt to stop the Cadillac. After receiving two blasts of Debree’s siren and traveling an additional one and a half miles, the Cadillac pulled over. Debree testified as follows regarding his pursuit:
Counsel: And can you tell us what happened after you activated the emergency lights with respect to what you observed the occupants in the car doing?
Debree: What I recall, both the driver and the passenger were speaking to each other. The passenger of the vehicle at that time from what I can remember placed his hand on the rear view mirror, seemingly adjusting it to see behind him. At one point the passenger even looked over his left shoulder directly at me.
Counsel: Did this sеem unusual to you based on your experience?
Debree: Yes.
Counsel: Why is that?
Debree: Well, I felt a little uncomfortable, first of all, if he could see me. The vehicle wasn’t pulling over immediately. They both seemed to be conferring between each other, and they *974 were not pulling over for me immediately.
Rec. vol. II at 43. Based on his observations, Debree radioed for assistance because the men matched a "drug courier” profile and acted “suspicious.”
Debree approached the Cadillac to inform its driver, Barry Pitchford, of the discrepancy in the registration check. Because Walraven, a passenger in the vehicle, admitted ownership, Debree asked both men to produce their driver’s license as well as the vehicle’s registration. After running a negative check with the NCIC on the men, Debree again ran a license plate check. Although Debree reported the plate as CYR 490, he noted that the dispatcher recorded the plate as CYR 409. A transcript of Debree’s correspondence with the dispatcher during his pursuit of the Cadillac indicated that the dispatcher had made the same mistake at least two previous times without Debree’s knowledge. This time, however, Debree corrected the dispatcher and the license plate was properly idеntified as belonging to the Cadillac.
Between two and three minutes later, Debree’s backup, Sergeant Lance Robinson arrived. With Robinson positioned at the rear right side of the Cadillac, Debree again approached the vehicle tо return the licenses and registration. When Debree asked if they were transporting any illegal narcotics or firearms, both men responded “no.” Debree then requested to search the Cadillac. According to Debree, Pitchford replied: “I don’t know why yоu would want to, but I imagine you can go ahead.” Walraven thereafter said: “Sure, go ahead.” Debree also testified that when he asked to search the trunk, Walraven pushed the release button inside the glove box and Pitchford opened the truck. Insidе the trunk, Debree recovered a blue satchel which contained two kilograms of cocaine. Both men were taken into custody and transported to the Albany County jail.
II.
Walraven initially contends that Debree’s random registration check on his out-of-state vehicle violated the Constitution’s privileges and immunities clause, U.S. Const, art. IV, § 2, and equal protection clause, U.S. Const, amend. XIV, § 1, by impeding his right to interstate travel. We disagree. While the right to travel freely interstate is a “basic right” embodied in the Constitution,
United States v. Guest,
III.
Walraven next asserts that Debree’s initial stop of the Cadillac violated the fourth amendment’s proscription against unlawful seizures. According to Walraven, Debree’s failure to remedy the dispatcher’s incorrect relay of the Cadillac’s license plate until after the deputy had stopped the vehicle to inquire as to its registration was an unreasonable mistake of fact, or in the alternative, merely support for a pretеxtual stop. The district court disagreed:
Notwithstanding the officer’s failure to detect the dispatcher’s error on three separate occasions within a three and a half minute period, he unquestionably *975 acted in good faith upon the report when he pulled defendants’ vehicle over to investigate the perceived registration discrepancy.... [T]here existed in his mind a belief which would alert a reasonable person that some sort of crime had been or was in the process оf being committed.
Pitchford,
The district court implicitly recognized that whether Debree’s failure to detect the dispatcher’s error tainted his stop of the Cadillac and subsequent discovery of the cocaine depended upon the objective reasonableness of his inaction.
See United States v. Leary,
Mindful of these principles, we sustain the district court’s finding that Debree acted in an ostеnsibly reasonable manner in failing to identify the dispatcher’s mistake. Based upon the circumstances as he perceived them, Debree had an “articulable and reasonable suspicion” that his stop of the Cadillac would reveal the existence of a crime.
See Delaware v. Prouse,
IV.
Walraven аrgues that even if De-bree’s initial stop of the Cadillac was lawful, no legal basis existed for his continuing detention once Debree confirmed the vehicle’s registration. Walraven’s continuing detention is best described as an investigative detention. As we explained in
United States v. Espinosa,
While an investigative detention is a seizure within the meaning of the Fourth Amendment, it need not be supported by probable cause. An investigative detention is justified where specific and articu-lable facts and rational inferences from those fаcts give rise to reasonable suspicion that a person has committed or is committing a crime.
(citing
Terry v. Ohio,
Aside frоm the registration discrepancy, the district court cited the suspicious actions of Walraven and Pitchford, the men’s failure to promptly stop the Cadillac in response to Debree’s flashing lights, their nervous mannerisms, and Debree’s law enforcement еxperience as support for its finding that Debree reasonably believed the men had committed or were committing a crime. The district court justified De-bree’s detention of the men for the two to three minutes before Sergeant Robinson arrived as simрly prudent in view of De-
*976
bree’s perceived threat to his own well-being.
Pitchford,
That the fourth amendment “does not require police officers to close their eyes to suspicious circumstances” is beyond peradventure.
Espinosa,
V.
Lastly, Walraven submits that he did not consent to Debree’s search of the Cadillac despite Debree’s testimony to the contrary. No one doubts that an official may search a vehicle without probable cause if voluntary consent is given.
E.g., Rivera,
AFFIRMED.
