So if I owned a business , I could declare it a "violence free zone" and exile whoever I deemed violent?
This might be a better choice for a firing range than making it gun free.
I haven't checked whether my bank is a gun free zone , I am not sure that would be legal with present Ga. law.
But if given the choice of banking in a gun free zone , or a guns welcome zone, I would certainly choose the guns welcome zone for the greater safety.
