With all due respect Russ, the OP did say they have hired security at the store. Why would a manager need to approach him if they have hired security? Security signs up to be... Well.... SECURITY. If the manager wanted someone booted (and they absolutely have the right to boot anyone for anything), why didn't they have security ask him politely to leave? That is the logical first step, not calling the police when the OP wasn't breaking any laws, threatening customers. Instead, he was minding his own business, nothing illegal or "dangerous" about that. Imagine if every store just decided to call the cops out to kick people out they didn't want in the store? Police resources being wasted on such petty non-sense. There was nothing illegal, no one threatened, so where was the need for police?
