I just now got back from McPherson Sq. Right now it's a peaceful tent city with nary a police officer in sight. I was there for the General Assembly and the occupiers planted a symbolic occu-tree. Unfortunately I didn't see any recognizable DSA'ers.
The spokesperson from the Medical Committee advised the sleepers to get some rest now so as to be ready for a police assault at about 3 AM, when everyone like me has left. If you are younger and better at keeping warm than I am, it would be good to show up in the middle of the night to observe.
