"Search and seizure" refers to the legal process where law enforcement officers examine a person's property or belongings to find evidence of a crime. This process is governed by the Fourth Amendment of the U.S. Constitution, which protects individuals from unreasonable searches and requires law enforcement to obtain a warrant based on probable cause before conducting a search. A warrant is a legal document issued by a judge that authorizes police to search a specific location and seize items related to a crime. If officers conduct a search without a warrant or probable cause, any evidence found may be deemed inadmissible in court, protecting citizens' rights against unlawful intrusion.
