Under this bill, openly carrying a firearm — whether loaded or unloaded — within 500 feet of a "large public gathering" becomes a criminal offense, but only after a law enforcement officer has verbally warned the person that such carrying is prohibited in that area. A "large public gathering" is defined as 200 or more people assembled on public property for events like protests, rallies, marches, parades, vigils, or similar First Amendment-protected activities. Once warned, a person must either conceal the firearm (if they are legally permitted to do so) or move more than 500 feet away from the gathering; returning to openly carry after initially complying also constitutes a violation, punishable as a class B misdemeanor.
