This morning I spoke to one of the people that spent the night in Ferry Park, which is north of Justin Herman Plaza. Seems there were a few turn of events that they did not plan on, such as the sprinklers going off in the middle of the night! They also did not expect the Police to come by and wake them up either. From what I was told the SFPD just checked Ids, and a few of them were detained about 20 minutes, the rest just walked away from the Police and back to the established camp/protest. The "protesters" were told that it is against the law to sleep in a park in San Francisco.
