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.
The 4th Amendment protects individuals from arbitrary searches by the government. It requires law enforcement to have a warrant, based on probable cause, to conduct searches and seizures of property.
The 4th Amendment was influenced by the colonial experience with British general warrants and writs of assistance that allowed broad and warrantless searches. Its ratification reflected a commitment to personal liberty and privacy in a newly independent nation.
The legal principle that evidence obtained through violations of the 4th Amendment cannot be used in court.
