This question mostly goes to americans (or residents of any other country where it is legal).
Do you have any firearms? For what purpose do you have it and have you ever used it?
Everyone else can discuss if people should have a right to have a gun or not.
I currently don't have one, but I've been thinking about getting one. Since I don't really feel that safe in our home because seeing a lot of crimes on the streets in the news, I think it is much better to be prepared in case I encountered problems which involves criminals of all sorts.
