I understand your point but given the fact that he was stopped by an plain clothes cop in an unmarked car in a city that has previously had trouble with bad guys impersonationg cops wouldn't you have been careful ? I think most of us would react like you described if we were pulled over by a marked patrol car with a uniformed cop behind the wheel. When we rented a car in Miami only 3 years ago we were warned by Hertz about people impersonating cops and what to do if we were pulled over.
