in states where private business no gun sign has force of law, do anti gunners actually know it has that power?

as CCW holders I am sure we all research our state's gun laws, learning when/where it is illegal to carry so we dont get slapped with a misdemeanor etc. but do anti-gunners actually know anything about their states gun laws? for example if a restaurant owner sees you are carrying in his "no gun" business, how likely that person would actually call the cops "cuz the gun law" vs simply asking you to leave? via /r/CCW http://ift.tt/2apqAw3
