I spent a career carrying typically either an M16 or an M4 Carbine. An M4 Carbine fires a.223 caliber round which is 5.56mm at about 3000 feet per second. When it hits a human body, the effects are devastating. It's designed for that. That's what our soldiers ought to carry. I personally don't think there's any need for that kind of weaponry on the streets and particularly around the schools in America.
