And how is it the government's business whether someone is acting rationally or irrationally in taking their own life? It's their right to do so, even if I disagree with them actually doing it. It's not my place or your place to try and force them not to (or even make it more difficult for them). Where do you draw the line? Virginia got rid of its 30-day time limit because it was shown to be ineffective, and yet that's the "gold standard" that pretty much all gun control advocates have called for. How long would you make it? 90 days? One gun a year? At some point, it's clearly excessive. And that's not even looking at collectors (who, for example, often want to purchase matched sets or consecutive serial numbers). Kansas was just the first I had pop up from a Google search. There are no complete nationwide statistics, because a lot of states don't release information on CCP holders. I've seen similar reports from Florida, Texas, and Utah, which all issue a significant number of permits. I'll see if I can dig those reports up for you. EDIT: This looks at a NY Times article about North Carolina and shows that CCP holders are 5 times less likely to kill someone than the rest of the population. The chart on page 58 of this PDF provides data from some more states. I'm not saying that the problems can't be overcome, but there would be significant legal ramifications in other areas as well. It's not a quick or easy thing.
