Modern technology has made it possible for police agencies to use unmanned aerial surveillance to search wide areas quickly. Drones are available to even private purchasers who can afford them, with no current state laws restricting their use. Sen. Joe Negron, R-Stuart, introduced a "Freedom from Unwarranted Surveillance Act" (SB 92) that forbids law-enforcement agencies to use drones to track suspects, without a search warrant. The bill would not apply to federal agencies or to state, county or city law enforcement officers who are working with the federal government in anti-terror investigations or other operations authorized by the Department of Homeland Security. Residents could obtain civil court orders to stop drone intrusion into their property and any evidence gathered by such surveillance without a warrant would be inadmissible in court.
