The Fourth Amendment to the U.S. Constitution was a response to the overreaching of the British crown during the latter days of their rule in the Americas. Colonists up and down the Eastern Seaboard were subjected to British troops entering their homes without cause and searching their possessions and persons.
It says, “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.”
