As Glenn Reynolds over at Instapundit would say, read the whole thing.
What I like about this piece on guns, gun crime, and gun criminals is what it does not pretend to know. It does not offer a panacea, or (pun intended) a magic bullet. It does not focus on what people think, but rather what they do. Which is all we can respond to, when you get right down to it. How do people actually act?
