Pentagon shows off new ray gun "Washington- The US military has tested a heat ray gun that produces an intolerable heating sensation on the skin designed to repel enemies or disperse hostile crowds without using lethal force, the Pentagon said Thursday. The device, called the Active Denial System, sits on top of a military vehicle and unleashes an invisible beam at the speed of light that penetrates the skin by less than a millimetre but enough to cause pain sensors to react."

Far fetched, well some of the police I've seen around here are more outfitted with (unnecessary) weapons than troops in Iraq. You'd think the street war was starting tomorrow and most of these folks probably have IQ's less than 90.
