You mean dumb? I think DMX was arrested for a similar charge a while ago but i think it involved him being caught in an airport with blow and claiming to be a federal officer....
James Stewart was arrested today for impersonating an officer. According to reports, Stewart has blue and red lights in his Toyota Tundra and used them to attempt to pull over another car. Unknown to Stewart, two off duty Highway Patrol officers were inside the car. When they displayed their badges as Stewart pulled up along side, Stewart sped off. He was later arrested at the Orlando International Airport. Click the link below for the full story.
