I would have to agree with foghorn leghorn.
Also why would we want to keep a gun out of a felons hands or a person who due to his condition is a danger to himself or others, but at the same time allow them to drive a car?
If a medieval man at arms was transported to the 21st century and had to chose which was deadlier. A big truck or a machine gun if he wanted to kill as many people in a crowded area as possible in a short time. I bet he would pick the truck.
But since hollywood doesn't particularly glamorize mass homicide with vehicles as often as with guns we do not see this happen as often.
So we blame the guns, the illness, the convicted felon, but when do we blame the media?
