The Fourth Amendment to the US Constitution states that people have a right to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures. And that any warrant to seize them be submitted by an oath or affirmation describing the persons or things to be seized and the place to be searched. Like the others, this was ratified because the British had violated this idea rather greatly, and the Founders wanted to make certain our new government would not fall into the same practices as the one we had fought so long to get away from.
