Some people just shouldn't be allowed arms. They demonstrate they are too stupid and have forfeited their right by reckless, impulsive behavior with firearms. This clown waves an AK-47 around with his thumb on the trigger guard, a recipe for a serious tragedy. He probably didn't even know how to check to make sure it was unloaded before he borrowed it from somebody else.
He is right in a way, the Founding Fathers did not have pathetic weaklings like him in mind when they wrote the Second Amendment. They believed that if men like this ever constituted a majority it would be time for another revolution.
