The Fourth Amendment provides 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.” It’s the reason your home can’t be searched by the police without a search warrant that has been supported with probable cause to believe that evidence or fruits of a crime will be found there.
