Now that I've watched it through, a more powerful video than I realized at first. By the end one sees a powerful use of the human mic, as police are told they are being granted a moment of peace to retreat. And they do.
i am glad the police retreated at the end. but this was a pathetic example of brutality. And recorded 9 ways to sunday from many angles. you just have to search UC Davis on g+ to realize that this will not go quietly into the night.
