While at the Harry Hays Building (federal government offices) protesters were told to stay off the plaza area, because it was "private property". The person seen her being taken by police came back there at the end of the protest, and was arrested. However, I don't have the details of what if anything he was charged with. I think I heard him say they said there was a warrant on him.
Protester Denise Ogonoski can be seen in the back seat, being taken away by police. She was taken in because she had climbed up a light pole to put up a Tibetan flag outside the Chinese consulate. One thing that concerned me after this happened, was I overheard another protester asking where Denise was taken, and the police officer didn't seem to know or care to find out.
