The only issue with the mad man shooting spree is that if you have a concealed carry, you can not pull your weapon unless the mad man directly aims at you and you have no other option.
I dissagree with this. If I am somewhere, and someone starts pulling the trigger on innocent people, then I think it should be partly my responsibility to control the situation until law enforcement arrive.
I don't know about NC's laws, but here in Okla you ONLY have to be in FEAR OF YOUR LIFE. That means, if a 350 Lb Ape (or anyone else for that matter) attacks you with the purpose to do you Grave Harm, you have the right to BLOW him away with the STATES BLESSING lease:
