C. holding this framework applies whether the traffic stop is based on probable cause or reasonable suspicion
D. holding that there is no  1983 cause of action for false arrest unless the arresting officer lacked probable cause
E. holding that a conclusion that reasonable suspicion supported the stop of a vehicle was subsumed within the trial courts ruling that the officer had probable cause for the stop
