The police arrested 1 (I think) person in a tent and then all left. About 2 dozen cops mostly bike cops but a few in cars made the announcement that the park was closed at about 10:15. They took down the tent only and arrested the person.
There was another group of people willing to get arrested, who locked hands, but it appears they were left alone. No riot gear or attempts to clear the entire park. As far as I could tell nobody was pepper sprayed. While, once again, I think the arrests were a serious mistake, I applaud the police for their professionalism.
