Have you or do you know anyone that has killed an intruder with a gun ?
Heh, no guns... But today I had to call the sheriff because my neighbors house was being cased- we live in a rural area. We think they took off because they realized my hubby was watching them. The week before Christmas my sister saw a man trying to break in her neighbors house- she lives in an urban area. And we live in two different states.
Personally, I don't use firearms for home defense. I have other weapons for that.
