There was no incident. An officer actually was engaged with Ian in conversation about the "products at the threat of violence." He first said that he agrees that everyone should live their lives how they want without harming anyone, and then called LEAP ridiculous. He said he's against prohibition and that drugs should be illegal (He didn't know what prohibition meant?) Once we clarified he made it perfectly clear that he is against drug legalization.
Anyway, that same cop was at the festival all day. There was a much bigger Earth Day fest going on at the same time. He was most definitely in the area while we played poker. In fact, another man at the park was arrested by him on an outstanding warrant, but the cop didn't even come close to that poker table while the game was going on.
