They should all be forthcoming with the kind of surveillance they're using. They obviously can't announce every operation the drones are used for, otherwise that kind of defeats the purpose. Drones should not be used as surveillance, like swoop down and look through windows or even in back yards. That kind of surveillance should require a warrant. I don't know what they're doing with drones in the US, specifically and with what kinds of warrants, so that is a good civil rights question.
