I watching a COPS marathon before coming in to work this afternoon. Officers pulled over a man driving a suspected stolen car. Here's part of what went down.
OFFICER: Sir did you steal this car?
SUSPECT: (Puzzled Look) Did I steal this car?
Needless to say, after a brief scuffle, COPS took the perp in to custody!
In my opinion, when you repeat a question that an officer of the law asks you. You probably did steal the car!
