From the First Amendment of the United States Constitution:
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.
The entire First Amendment has been increasingly ignored in recent history, and things have become especially worse during the Bush administration. This is no surprise, considering what President Bush himself blatantly revealed of what he thought about the Constitution of the United States:
Stop throwing the Constitution in my face! It’s just a goddamned piece of paper!
