Illinois has established new rules regarding the use of drones by law enforcement agencies. The Drones as First Responders Act outlines the circumstances in which drones can be used, including counter-terrorism efforts, search and rescue operations, and crime and traffic scene photography. The act also requires agencies to destroy any information gathered by drones within a set timeframe unless there is reasonable suspicion that the information contains evidence of criminal activity or is relevant to an ongoing investigation or criminal trial. The act prohibits law enforcement from using facial recognition software that works in conjunction with drones and equipping drones with weapons.
