What Does the Fourth Amendment Mean? The Constitution, through the Fourth Amendment, protects people from unreasonable searches and seizures by the government. The Fourth Amendment, however, is not a guarantee against all searches and seizures, but only those that are deemed unreasonable under the law.

Arizona, 437 U.S. 385 [1978]).
