Five, what about the safety of your family when some half blind Clint Eastwood mofo shoots somebody you know (god forbid) by mistake? Still worth it? Or you shoot somebody in the heat of the moment and you made the wrong decision? How do you deal with that, emotionally, financially etc etc? You're carrying a weapon that will definitely kill someone just by a twitch of your finger. Untrained, your a liability, believe me I know.
