Most drones don't kill. Instead, they like to watch. We usually think of the small, unmanned aerial vehicles in terms of grainy overhead shots of desert explosions, but less than five percent of the U.S. overseas drone arsenal consists of those lethal Predators and Reapers. As Shane Harris details, the remainder are mostly Peeping Toms engaged in overhead reconnaissance and surveillance. For a variety of uses, drones will become increasingly common at home and abroad, with increasing autonomy.
