Wisconsin Statutes Police Regulations (Ch. 163 to 177) § 175.55. Use of drones restricted

(1) In this section:

(2) No Wisconsin law enforcement agency may use a drone to gather evidence or other information in a criminal investigation from or at a place or location where an individual has a reasonable expectation of privacy without first obtaining a search warrant under s. 968.12. This subsection does not apply to the use of a drone in a public place or to assist in an active search and rescue operation, to locate an escaped prisoner, to surveil a place or location for the purpose of executing an arrest warrant, or if a law enforcement officer has reasonable suspicion to believe that the use of a drone is necessary to prevent imminent danger to an individual or to prevent imminent destruction of evidence.
