Drones barely mentioned in debates. We may think of them as overgrown model airplanes, but they come in different sizes. Planned are drones as small as humming birds, or as tiny as a bee that can fly through a window or through building ducts. They'd be released as individuals or in swarms. Fancy going to bed at night wondering if a horde of armed mechanical insects might fill your immediate sky and perhaps home in for a photo-op or something more lethal.
