Under the Fourth Amendment to the US Constitution, the police are prohibited from conducting a search and seizure without "probable cause." 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 prohibits the United States government from conducting "unreasonable searches and seizures. Fourth Amendment found easy acceptance in the Supreme Court30 and that acceptance controlled decision in numerous cases. The Fourth Amendment protects us from unreasonable search and seizures of our person, our house, our papers, and our effects. The Fourth Amendment of the United States Constitution protects us all from illegal searches and seizures. But cracks in the Fourth Amendment have weakened our personal security. It also prevents unlawfully seized items from being used as evidence against them in criminal cases. The Fourth Amendment establishes that the government cannot search citizens without reason. Terms of Service have little or no effect on Fourth Amendment rights.
