This would-be crook had a really, really bad day. It started when he decided to rob a store, and got worse when his gun slipped out of his hand during the attempt. The store's video camera caught the whole incident, which included the guy's failed attempt to jump over the display counters to retrieve the gun and almost losing his pants as he escaped the store - without his gun.
The old adage "Crime doesn't pay" was probably invented for this guy. Watch and enjoy.
