6.Going Armed To The Terror Of The People
By common law in North Carolina, it is unlawful for a person to arm himself with any unusual and dangerous weapon, for the purpose of terrifying others, and go about on public highways in a manner to cause terror to others. The N.C. Supreme Court has said that any gun is an unusual and dangerous weapon for purposes of this offense. Therefore persons are cautioned as to the areas they frequent with firearms.
