The Fourth Amendments

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized, except if George W. Bush authorizes the National Security Agency to spy on Americans, and that ought to comfort you.

Yeah, makes us feel warm and fuzzy ...
