The critical art ensemble is a group of people who try to bring attention to social issues (which sometimes you wouldn't notice otherwise) through weird/creative real life performances
I really encourage you to check out this talk by one of their members, which is about all the pushback they've received through the years form the police, the law, politicians and more.
In my opinion it really goes to show that in reality we are pretty far from effective free "speech"
