ORS 837.320: Authorized use upon issuance of warrant; exigent circumstances.

(1) A law enforcement agency may operate an unmanned aircraft system, acquire information through the operation of an unmanned aircraft system, or disclose information acquired through the operation of an unmanned aircraft system, if: (a) A warrant is issued authorizing use of an unmanned aircraft system; or (b) The law enforcement agency has probable cause to believe that a person has committed a crime, is committing a crime or is about to commit a crime, and exigent circumstances exist that make it unreasonable for the law enforcement agency to obtain a warrant authorizing use of an unmanned aircraft system. (2) A warrant authorizing the use of an unmanned aircraft system must specify the period for which operation of the unmanned aircraft system is authorized. In no event may a warrant provide for the operation of an unmanned aircraft system for a period of more than 30 days. Upon motion and good cause shown, a court may renew a warrant after the expiration of the 30-day period. [2013 c.686 §3; 2015 c.315 §3]
