The whole point of the Fourth Amendment is not to completely stop the police, because the amendment can be waived if an officer has a warrant, or a person’s consent. The Fourth Amendment states that generally a search or seizure is illegal unless there is a warrant, or special circumstances. Technically stating that a citizen is protected by the Fourth Amendment, until a government employee gets a warrant, and then they can invade a citizen’s privacy. Also people state that the FISA Court’s warrants are constitutional, but the NSA’s surveillance is unconstitutional. Even though people do not like the NSA’s surveillance, the NSA is legal because the FISA Court that the people did not mind makes it legal. Next a search warrant is not needed
