“Demonstrators who engage in civil disobedience – defined as non-violent unlawful action as a form of protest – are not protected under the First Amendment. People who engage in civil disobedience should be prepared to be arrested or fined as part of their protest activity. If you endanger others while protesting, you can be arrested. A protest that blocks vehicular or pedestrian traffic is illegal without a permit.”
