Tenn. Code Ann. § 40-6-105: Issuance of search warrant - Issuance of "no knock" search warrant prohibited

(a) The magistrate, if satisfied of the existence of the grounds of the application, or that there is probable ground to believe their existence, shall issue a search warrant signed by the magistrate, directed to the sheriff, any constable, or any peace officer, commanding the sheriff, constable, or peace officer immediately to search the person or place named for the property specified, and to bring it before the magistrate.
