SEATTLE (AP) — The Seattle City Council says police and other departments must obtain the council’s approval before using certain cameras and drones for surveillance.

The council passed an ordinance Monday in response to concerns over 34 cameras that were installed across the city without public notice. The council says it will review camera operations and data management to protect the public’ privacy and civil liberties.

An exemption in the new law allows police to use surveillance technology under a search warrant.
