Amendment I
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
This means I have the right to say anything I want and any attempt, by anybody, to stop me is a violation of the 1st Amendment. It also means the press doesn't have to report the truth, they can report what they want. And I can drag policemen off their horses if they try to make me protest from behind a barricade.
