They may be crazy, but they are not stupid, if you intend on killing a bunch of people where are you going to go? An NRA meeting or a gun free zone? They aren't hard to find, there is a big sign posted for anyone to see.
It just doesn't work like this

you missed my point maybe I made it badly
lets say we go with your way of doing things
then in my opinion everyone has to be armed ready to go at a moments notice
im sure if everyone was like you or aj these idiots would get shot the fuck up when they went on a spree
either everyone is in or no one is
I just think it would be better if guns were hard to get
I will concede as it stands if I lived in the us I would defo want weapons
