What is the function of a search warrant?

The function of a search warrant is fundamentally to provide law enforcement with legal authority to conduct a search of a specified location or property. A search warrant is issued by a judge or magistrate and is based on probable cause, meaning there is a reasonable belief that evidence of a crime will be found in the place to be searched. This legal requirement ensures that searches are conducted fairly and respects the constitutional rights of individuals, particularly the right to privacy. By requiring a search warrant, the legal system maintains a balance between the need for police to gather evidence and the protection of citizens' rights.

The other options do not accurately represent the specific role of a search warrant. A warrant does not allow for arrests without cause, authorize the use of force, or permit interrogation without evidence. Each of these actions requires different legal justifications and processes distinct from the issuance and execution of a search warrant.
