The Fourth Amendment,

http://www.billofrights.com/fourth_amendment.htm

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.

� The Fourth Amendment to the United States Constitution is one of the provisions included in the Bill of Rights. The Amendment guards against unreasonable searches and seizures, and was originally designed as a response to the controversial writs of assistance (a type of general search warrant), which were a significant factor behind the American Revolution.
