"Ladies and gentlemen of the jury, I submit that had he been wearing Armani it might have been an ostentatious display, but you've heard testimony here today that the display was in fact sarcastic and flatulent, yet understated..."
I don't know if you are LE and have a finite definition of what is and is not brandishing. BUT, where I come from that is called "brandishing". Nevada. Back when it was very "pro-gun". Pull a gun out and set it on your table without a good reason is likely to get you kicked out on the spot. Any further argument would result in a severe beating. Probably repeated if you don't seem to come forth with the attitude, that if you carry, you damn well don't pull it out of the holster in a public place of business. Unless you need to use it.
I wouldn't have a second thought about telling a patron to "Get the fuck out of my place of business, if you unholster that here." "And, if you want to come back we will discuss your habits before you return."
Wearing Armani is a lot lower on my list of stupid things to do than unholstering a gun in a public place of business. So you know there was no sarcasm intended, I mean it about pulling out a gun and laying on a table. The only reason I said splitting hairs is you seem to think it's okay to pull out a gun in public. As long as they don't point it at someone, right?
Thus my statement about "brinksmanship". We don't need to take this to the line with public displays of stupidity. We need to take it to the line in Legislatures across the nation and Congress in a legal manner. And showing the public us 2A people are not here to threaten or look mean. Most cases quite the opposite. Again, not being sarcastic.
