The guy with the grey goatee was at the side door where the cop was beaten, and in the video of that one can see him kind of routing people. In that same video and photos, you can also see another guy standing on a ledge to the left of the door who is peculiarly only watching the crowd not the door area. I get a gut feeling that he is a crowd control / observer. The photos I've seen give me the feeling of seeing a few people strategically route incomers, because they do not face the door, the center of action, but instead seem to be dedicated to guiding people to come to the door. The guy with the long pole seems to be a setup - who carries a really long pole to a protest event? What is the purpose? Not to hold up a flag. He hits the cop with the pole, then runs away. WTF. Why run? And his face is obscured with parka.

It all makes me suspicious of a false flag attempt to shape the narrative in order to later position the event as a riot.
