Drew Peterson hopes a photograph of himself with actor John Travolta will help him fight a felony gun charge. His public relations firm released the picture Wednesday night. They say it shows the former Bolingbrook police sergeant carrying a weapon on duty that prosecutors now say violates state law. The AR-15 was confiscated several months ago. And he was charged last week. The photo was apparently taken a few years ago when Travolta was in the Chicago area promoting a movie, and Peterson was assigned to protect him.
