On my way to the Bernie Sanders Healthcare Rally in Yerba Buena Gardens I came upon this scene. Just before the cops took him down, I was standing next to him waiting for the light to change. At that point he was not acting violently, just mumbling about the CIA. I was behind him when two of the officers rushed him. He turned and nearly ran into me. By the time I got my camera out, he was already on the ground.
The Bernie Rally was excellent. I'm starting to recognize some of the activist regulars. The Socialist groups are always there! I recorded about half of his speech before a group of animal liberation folks tried to interrupt the event.
Things devolved from there.
Skip to about the middle for an interview with one of the meat protesters.
I hope those audio files don't give you too much trouble.
