Here's the scene in the Wisconsin's capitol building tonight:
Around the 50-second mark, some of the protesters begin to push the state troopers who are trying to control the crowd. One protester gets in the face of another trooper, and another protester begins shouting "Do not touch me! Do not touch me! Do not touch me!" It's no "Don't tase me, bro" moment, but still quite a scene.
And then, in a nice twist, the protesters begin chanting "peaceful!" which is apparently what they do after some in the crowd behave horrendously.
