are criminals. It's foolish to think they are going to hand in guns or register guns they intend to use to harm other people. Wasn't every place where a "massacre" has occurred been a gun free zone? We certainly can make it harder for new guns to be acquired, but that doesn't really address the untold # of guns already in criminals hands. I do think there is something to be said for mandatory prison sentences. Our current deterrents aren't all that strong. I also like accomplice sentences.
