What constitutes reasonable suspicion for a Terry frisk during traffic stops? State v. Parke Explained

In State v. Parke, the Utah Court of Appeals addressed when police officers may conduct protective frisks during routine traffic stops under the Fourth Amendment. The case provides important guidance on distinguishing between reasonable suspicion and mere hunches in Terry analyses.

Background and Facts

Officer Anderson stopped Parke for a traffic violation at 9:30 p.m. During the stop, Anderson observed Parke make shoulder movements that he interpreted as reaching toward his waistband area. Based on his experience, Anderson believed Parke might be concealing weapons or narcotics. When ordered to place his hands outside the vehicle, Parke became “somewhat agitated” and questioned the command, though he ultimately complied. Anderson testified that his patrol area was “very dangerous.” Anderson then ordered Parke from the vehicle and conducted a protective frisk, discovering a knife and subsequently finding methamphetamine during a search incident to arrest.

Key Legal Issues

The central issue was whether Anderson’s protective frisk satisfied the Terry v. Ohio standard requiring reasonable, articulable suspicion that Parke was armed and presently dangerous. The court applied the totality of the circumstances test, examining whether specific facts supported the officer’s belief rather than relying on subjective hunches or generalized concerns.

Court’s Analysis and Holding

The Court of Appeals reversed, finding the frisk unconstitutional. The court emphasized that mere furtive gestures do not create articulable suspicion, as innocent explanations exist for shoulder movements like reaching for a wallet. Parke’s “agitated” response was deemed normal nervousness during traffic stops, not threatening behavior. While high crime areas factor into Terry analyses, general statements about patrol area dangerousness cannot substitute for individualized suspicion. Critically, Anderson mitigated potential dangers by ordering Parke’s hands visible and removing him from the vehicle, reducing justification for the frisk.

Practice Implications

This decision reinforces that officers must articulate specific facts supporting reasonable suspicion beyond subjective interpretations and area reputation. Practitioners should scrutinize whether police testimony describes concrete, observable behaviors rather than conclusory statements about suspect movements or general safety concerns.
