Open Carry alone is NOT Reasonable Articulable Suspicion (or RAS) as required by law to stop and detain someone who is not then or reasonably suspected of committing an unlawful act. The other thing wrong was that the reporter stated that background checks were required when buying a gun. That only applies to FFL (Federal Firearm Licensed) dealers, NOT individuals. Also, a business has to either have some sort of "No Guns" signage to forbid you entry OR they have to ask you to leave. Calling the cops without either of those is NOT legal grounds for a trespassing charge. The Most a cop can do LEGALLY at that point is ask you to leave. If you are ever asked to leave a business by someone who works there, LEAVE, RIGHT THEN. This is NOT the time to argue with them! Areas that you are also prohibited from Openly Carrying include but are not limited to: Places that serve alcohol for on site consumption including restaurants; Post offices; Polling stations; the secure areas of airports and Veterans Affairs Hospital buildings AND Grounds.
