Q. State the clause from the Fourth Amendment that requires a warrant for searches and seizures. What does that mean?
According to the National Archives and Records Administration (NARA), the Constitution was created as a replacement for the Articles of Confederation in 1787. In 1789, the first congress of the United States created 12 amendments to the constitution that outlined the "immunities of individual citizens" (National Archives and Records Administration, Bill of rights, n.d.). Only 10 of the original 12 were ratified; these 10 amendments came to be known as the Bill of Rights.
The Fourth Amendment is the part of the Bill of Rights that guards citizens against unreasonable searches and seizures, as well as the requirement of a warrant to be judicially sanctioned and supported by probable cause.
From your question, it sounds like you are being asked to identify a section of the Fourth Amendment, a specific clause (or sentence), that talks about the requirement of a warrant for searches and seizures.
