Ok, so it's dark out that night, you hear someone in the bushes.
Your blood chemistry is full of (anders or gene fill in the blank).
You are scared nearly to death.
Are you thinking rationally when you are in such a state?
So- if a non-rational person cannot be trusted with a gun, then which one of us can?
One i saw on the news: even a sadder case of a man who shot his daughter's face off, becasue she hid in the closet - they heard noises, and when he opened the closet holding his gun - she jumped out and yelled boo!
