No reasonable person would dispute that walking into a retail store openly carrying a firearm is highly disruptive conduct which is virtually certain to create a disturbance. This is so because when employees and shoppers in retail stores see a person carrying a lethal weapon, they are likely to be frightened and possibly even panicky. Many employees and shoppers are likely to think that the person with the gun is either deranged or about to commit a felony or both. Further, it is almost certain that someone will call the police. And when police respond to a “man with a gun” call, they have no idea what the armed individual’s intentions are. The volatility in such a situation could easily lead to someone being seriously injured or killed.
