United States v. Willie Navarette, 996 F.3d 870

Early morning traffic stop for a nonworking driver-side headlamp; officer asked for license/registration and could not find a license in Navarette’s name.
Officer learned Navarette was on federal probation for a weapons offense; during the stop she saw him pat his pockets and asked him to step out; a loaded magazine was visible in the driver-door pocket.
After Navarette moved toward the car, the officer detained and handcuffed him, advised Miranda, obtained consent for a patdown (which revealed an empty holster), and observed a handgun in the center console; further search revealed two more guns, ammunition, and mail addressed to Navarette.
Navarette moved to suppress the evidence as the product of an unlawful search/overlong detention; the district court denied the motion after a suppression hearing.
At trial Navarette testified he was merely test-driving the vehicle and unaware of the weapons; the government impeached him with prior, inconsistent testimony from the suppression hearing and the jury convicted him under 18 U.S.C. § 922(g)(1).
On appeal Navarette challenged (1) the denial of suppression (arguing the stop became an unlawful arrest without probable cause) and (2) the use of his suppression-hearing testimony to impeach him at trial (invoking Simmons).

Issue	Navarette's Argument	Government's Argument	Held
Whether the traffic stop was unlawfully prolonged or transformed into an arrest without probable cause, so that suppression was required	The stop exceeded the time needed to address the headlamp violation and became an arrest unsupported by probable cause	Officer’s actions (identity checks, inability to find license, plain-view magazine, knowledge of probation for weapons offense, suspicious movement) justified continuing the stop based on reasonable suspicion of other criminal activity	Court held the initial 21-minute stop to investigate the traffic offense was lawful; when officer observed magazine and knew probation status, reasonable suspicion supported detention and further search; suppression denied
Whether the government could use Navarette’s suppression-hearing testimony to impeach him at trial despite Simmons	Suppression-hearing testimony should not be used against him at trial (per Simmons)	Prior inconsistent statements from a suppression hearing are admissible for impeachment; government used them to attack credibility, not as substantive proof of guilt	Court held admitting the prior testimony for impeachment was not plainly erroneous given circuit split and other circuits’ authority allowing impeachment use
