Conduct warrant less searches and seizures
The Fourth Amendment protects from illegal searches and seizures. It requires law officials to have a warrant in order to conduct a search. It is part of the Bill of Rights and was adopted in 1792.

Less privacy
The 4th Amendment prohibits unreasonable searches and seizures by law enforcement, which means that police cannot conduct searches or take property from individuals without a warrant or probable cause. This includes entering homes without permission or conducting searches without a valid reason.
Civil liberties include numerous provisions, many of them listed in the Bill of Rights, that protect person who are suspected of criminal activity. Among these are limits on how the police as agents of the government can conduct searches and seizures
Wrist of assistance
The Fourth Amendment requires searches and seizures to be "reasonable", which generally means that police must get a search warrant if they want to conduct a legal search or seizure, although there are exceptions to this general rule. If a search or seizure is "unreasonable" and thus illegal, then police cannot use the evidence obtained through that search or seizure in a criminal trial. This is called the exclusionary rule and it is the primary incentive against government agents violating your Fourth Amendment rights.
