The 4th Amendment to the United States Constitution protects individuals from unreasonable searches and seizures by the government. It states that 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.
This amendment was added to the Constitution in 1791 as part of the Bill of Rights, and it was intended to prevent the government from conducting arbitrary and unreasonable searches and seizures. The amendment requires that a warrant be issued by a judge or magistrate before a search or seizure can be conducted, and that the warrant must be based on probable cause and must specifically describe the place to be searched and the things to be seized.
