you are quite correct, google is your friend...There are more - Google is your friend.
reading your cites...several of the parameters are quite unique.
the 1968 case law involved an individual who was armed quote: ...armed with a carbine and four pistols, the defendant and three others drove on the public highways at night, firing bullets into a store and two homes) unquote.
as well as driving on the NC's highways, therefore, the case law parameters wouldn't apply to JQPublic walking in wally world, ad nauseam.
additionally, seems the kind NC legislature is trying to fix the jim crow case law with the legislation under HB 746...
"§ 14-277.6. Going armed to the terror of the people.
(a) A person who arms himself or herself with an unusual and dangerous weapon for the purpose of terrifying others and goes about on public highways in a manner to cause terror to the people is guilty of a Class 1 misdemeanor.
(b) No person shall be convicted of a violation of subsection (a) of this section based only on the person's possession or carrying of a handgun, whether openly or concealed."
and the number 'charged' in 2011 is interesting but the cite lacks the number convicted under the jim crow case law.
