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.
People should use the guns only if they have any threats to their life; only for the purpose of self protection they should use the guns. Otherwise common people don't have any reason to keep the guns.
