(Armed, DIY drone video)
Video of a handgun fired from a hovering drone into a wooded area has been posted on YouTube -- where it has gone viral -- apparently by an 18-year-old Connecticut student whose father says his son created the drone for a college class.
No one was harmed, nor has the teenager been arrested or charged. Still, the video has stirred fresh debate about the use of, and dangers posed by, drones.
SF author Larry Niven talked about armed drones called "copsyes" in his 1972 story Cloak of Anarchy:
Someone at police headquarters had expected that. Twice the usual number of copseyes floated overhead, waiting. Gold dots against blue, basketball-sized, twelve feet up. Each a television eye and a sonic stunner, each a hookup to police headquarters, they were there to enforce the law of the Park.
