If you’ve been on the battlefield, you’ve probably carried an M4 carabiner or something similar. And it fires a 5.56 (mm) round at 3,000 feet per second. And when it hits human flesh, it does terrible damage. It’s supposed to, and that’s what our soldiers should carry. I don’t want them on our streets; I don’t want them in our schools; I don’t think that most people are prepared to carry them. So I think we have to have a very, very serious look at why we even would consider having guns like that.
