Cop Shoots Himself in the Leg

It's bad enough that he shoots himself. It's worse that he's a policeman. It's even worse that he does this on camera. It's even, even worse that he does it in a room full of school children. It's even, even, even worse that he's trying to teach the children about the dangers of fooling around with firearms. It's even, even, even, even worse that he lets them know beforehand that the only reason he can handle guns is because he is a trained professional.
