Open carry is LEGAL in his state....right? Isf so, how can this be considered brandishing?
I am no lawyer, but consider if it is legal for you to openly carry a gun and you approach someone and you keep walking around that person and maybe stare at that person without saying a word. You could be charged with committing an act of violence or the threat of violence without saying a word and even if the other party started it. Heck, you could even be charged with threatening behavior even if you did not have a gun and didn't say anything threatening if you are approaching people in an unwise way. There are laws against threatening and menacing. I think in all jurisdictions, the armed person is held to a higher standard of behavior. You are supposed to be extra cautious even though it is inconvenient and even if you lose face. An armed person has the obligation to use extra common sense at all times.
The double circle around a table of people who are presumeably seated. Circling a target is a predatory instinct/ aggressive tactic. (Raptors, sharks, herding dogs 'circle'.)
Versus an alternative action of approaching the table, pulling up a chair, sitting briefly and then asking the group to please tone it down a little.
But then you still have to remember that restaurants are generally very noisy places and that you don't expect to find a crowd of church ladies in one at 4:30 Sunday a.m. Unless, of course, a tour bus load of senior citizens has just arrived and are trying to splain the menu options to the folks in the group who refuse to buy hearing aids.
