‘There is an oddly prophetic little scene in the science fiction movie They Live, filmed more than 20 years ago. In it, an alien disguised as a businessman radios in the location of the film’s main character to police. Within seconds a little camera-sporting flying saucer buzzes in overhead to start video surveillance.
Aerial surveillance drones are no longer the stuff of science fiction. In fact, in coming years they could be all over the US. That disturbs me.’
