Was chatting with a couple of local cops the other day... One of 'em is concerned about CCW... His thoughts are that the "kids" who are doing a lot of crimes are going to be MORE likely to shoot first if they even remotely assume that a potential victim has a firearm. He doesn't think that an armed population will deter these "kids" - his opinion is that they don't think that far in advance, and that they'll do their typical "He's got my money, and I'm gonna get paid," and then act, escalating their actions if they think that the victim might resist.
