Guns don't kill people - idiots with guns kill people

Alarming news from Indiana this week. A teenager has been charged with taking pot shots at trucks from several highway overpasses. The NRA might argue harmless teenage prank but a man was killed - completely randomly. The allegation is that this youth was out on a wholesome family activity - shooting and gutting deer - when he got angry and left. While others might just spin their tires and take off; maybe even hit a mailbox or two, this 17 year old had a gun and decided to release stress by shooting at vehicles on the interstate. Should a 17 year old - whether angry or not - be driving around with a gun? Probably not. He can't vote. He can't join the army. But he can carry a weapon. How does this make sense??
