Ignore him. There are many fine clients here with involvement in the criminal justice system. No threats have been made, and businesses can and do post photos of customers who cause issues or harass people on their premises. Police will not come when he calls, he is as clueless about the law as he is about everything else. If he actually had a lawyer, the lawyer would tell him to shut up, there is no actionable civil case, and certainly not one that he could win once his bullying here is taken into account. I like to imagine him on 911 berating the operator about when the cops should come, which days, which locations, and which officer is available so he can choose. As long as he shuts up and leaves, all is good
