From the Electronic Frontier Foundation:
San Francisco - The Electronic Frontier Foundation (EFF) filed suit [Jan. 10] against the U.S. Department of Transportation (DOT), demanding data on certifications and authorizations the agency has issued for the operation of unmanned aircraft, also known as drones.
... Traditionally, drones have been used almost exclusively by military and security organizations. However, the U.S. Customs and Border Protection uses drones inside the United States to patrol the U.S. borders, and state and local law enforcement are increasingly using unmanned aircraft for investigations into things like cattle rustling, drug dealing, and the search for missing persons.
