Couple things When people are saying limit or don't allow people with mental illnesses to own guns, what exactly is the definition of "mental illness." Anyone diagnosed with depression or anxiety? That would exclude a lot of people, including the majority of the teachers I know. I was always taught you don't consider your gun for self defense unless you are willing to use it to kill. Several years ago, my at-the-time boyfriend inherited a bunch of firearms from his grandfather. Since neither of us had shot any firearms for a long time (not even sure he ever had), we kept the guns as far away from the ammo as possible in our little apartment. We didn't want to be tempted to whip it out in case of an intruder because we knew we weren't confident and would probably end up disarmed and shot with it.
