Charged for discharge of a gun in a defense situation where the signs say no concealed guns allowed?

Has anyone seen or read anything on if someone has had to use a ccw gun to defend themselves or someone else while in a place that does not allow it? I wont say whether or not I will carry into a restricted place (not government) but I was wondering if you save lives, will these companies really hold it against you? via /r/CCW http://ift.tt/2mNomRz
