Whether reasonable suspicion exists when an officer relies on a driver's allegedly suspicious answer to an itinerary question without further inquiry, despite an objectively reconcilable explanation

In Rodrig uez v. United S tates, 575 U.S. 348, 354 (2015) , this Court held that an officer needs reasonable suspicion to prolong a traffic stop beyond its mission . As part of the mission of a traffic stop , an officer may ask a driver about the purpose of their travel , and suspicious answers might contribute to rea sonable suspicion. The issue here is whether reasonable suspicion existed when a primary factor relied on by the government was the Petitioner ’s allegedly suspicious answer to a question about her itinerary, but the explanation was objectively reconcilable with police surveillance and the questioning officer failed to i nquire further .
