I'm sorry, I didn't originally suggest a reason , because I knew you'd do this kind of BS equivocation. Fact is, there are plenty of reasons, justr because you can't envision any, doesn't mean you are right. And again you are wrong, HAVING these guns encroaches on no one's liberties. While they CAN be used incorrectly, if every one of these WERE used to kill one person in the US, we wouldn't be having this conversation. Guns don't kill, people kill. I have plenty of guns, and they never went off and killed anyone.
