The United States Constitution has proposed exclusive amendments to promote the rights of its citizens. One of them is the Fourth Amendment. The Fourth Amendment emphasizes that the right of the people to be secure in their persons, houses, and effects, against unreasonable searches and seizures, shall not be violated, and no warrant shall be issued, except for probable cause , supported by an oath or solemn affirmation, and in particular describing the location of the searches and the people or things to be seized (Worral, 2012).
