Drones over the USA are coming, most likely in 2015 or 2016.
I've been following the development of the FAA's study into allowing drones (also called UAS) to operate in the USA's air traffic control system for the past few years.
Six zones were to be specified as UAS testing areas by the end of 2012, but that has been put on hold over concerns of anti-privacy issues. But once that is sorted out, the project will be back in operation. Commercial, civil, and military drones will be in operation in the USA's airspace pretty soon. Personally I've been waiting for commercial operations to be allowed because I'll be in business as soon as it gets the green light... but knowing that the FBI, DHS, state & municipal police agencies, and the US military forces will also be operating drones to "better protect the citizens" is quite a bit scary to me.
