The Fourth Amendment to the US Constitution which is a part of Bill of Rights protects a citizen from unlawful searches and seizures.
It states that ' 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."
The prime goal of the amendment is to protect individual's right to privacy and liberty from unreasonable intervention from the state.
