> In that situation, Wessler warned police using facial recognition at a traffic stop could open themselves up to a false arrest lawsuit under the Fourth Amendment. Doesn't seem to me that a face scan would be against the fourth amendment, unless the situation in the article happens, a officer makes an arrest based solely off a face scan. In practice, it'll play out like drug dogs. A "hit" will give the officer reasonable suspicion to search the vehicle or pull the passengers out.
