I've seen a lot of pretty weird things about this. Like supposedly violent attackers calmly walking in line between velvet ropes. I've also talked personally to some people who were there and gotten some very conflicting reports about police behavior and the general knowledge of the protestors about what (if anything) was going on while they were there.
Having been present for some previous events that got reported in the news, and seeing the total lack of accuracy in the reporting, I'm very skeptical about the media accounts.
