The Missouri House has approved legislation intended to restrict use of aircraft for surveillance of people, farms and homes.
Law enforcement officials could use manned aircraft or unmanned aerial drones to gather evidence if they have a warrant or to prevent immediate danger. Journalists and news organizations would be barred from using unmanned aircraft for surveillance unless they have permission from the property owner.
Thursday's 87-66 House vote sends the bill to the Senate.
Supporters say the legislation seeks to protect privacy rights and prevent unwanted surveillance. Opponents said Thursday that the measure could hamper law enforcement.
