The Fourth Amendment, however, is not a guarantee against all searches and seizures, but only those that are deemed unreasonable under the law. The 4th Amendment to the US Constitution does two things.First, it protects individuals from searches and seizures that are unreasonable. The Fourth Amendment requires a warrant premised upon probable cause in order to seize someone or search their person or home. The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated. The touchstone of the search-and-seizure analysis should be whether government officials have done something forbidden to private parties. The Fourth Amendment protects "the right of the people to be secure in their persons, houses, papers, and effects" from unreasonable search or seizure. The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated. The Fourth Amendment regulates both searches and seizures.
