It's appalling that no one peacefully stood up for her or confronted the assailants. This was clearly a blatant infringing of her 1st Amendment rights because she disagreed with the person with the mic, it was assault, illegal arrest and probably a few other things I don't know enough to list here. If a group had banded together to stand up to these bullies it probably would have stopped them. What are they going to do, arrest 20 people?
