I walked through Caesar Chavez (or Wino) Park, at around 2 PM on the day of the “demonstration”. There were about 20 - 30 people milling around. There were also tents set up by SEIU, and a first aid tent supplied by some unknown group. On a normal day, there would have been that many public inebriates in the same area. No one would have been supplying them with first aid, however.
