The Fourth Amendment to the United States Constitution is part of the Bill of Rights and protects people from unreasonable searches and seizures by the government
. It sets requirements for issuing warrants, which must be issued by a judge or magistrate, justified by probable cause, supported by oath or affirmation, and must particularly describe the place to be searched and the persons or things to be seized
. The Fourth Amendment is not a guarantee against all searches and seizures, but only those that are deemed unreasonable under the law
. The extent to which an individual is protected by the Fourth Amendment depends, in part, on the location of the search or seizure
. The Fourth Amendment case law deals with three main issues: what government activities are "searches" and "seizures," what constitutes probable cause to conduct searches and seizures, and how to address violations of Fourth Amendment rights
