The Fourth Amendment to the U.S. Constitution states: "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." Does the mass collection of phone records violate the Fourth Amendment? Some argue that such collection is a gross invasion of privacy, while others contend that it is necessary to keep Americans safe. Does the collection of phone records constitute an unreasonable search and seizure? Or is it valid under the Constitution?
