Answer: 4th amendment
Explanation: The Fourth Amendment of the U.S. Constitution protects private citizens from unreasonable searches and seizures. The amendment reads, “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.” So therefore under the Fourth Amendment, police officers must obtain written permission from a court of law to legally search a person and their property, and seize evidence while they are investigating possible criminal activity. And evidence obtained through illegal searches is not admissible in a court of law.
