For having to paint my argument in such broad strokes so that you understand that these people were 100% in the wrong and deserved their consequences, despite the ridiculous and superfluous law they were attempting to protest.
The situation is a little more nuanced than "The cops did something I disagree with...POLICE STATE NAZIS HITLER"
Edit: I really can't believe you're trying to equate this with the Civil Rights Movement. One is a violent and systematic abuse of human rights and the other is a couple of cops saying "you can't dance here or we'll arrest you, sorry." and then arresting the people who started dancing like buffoons.
