The US Department of Homeland Security is developing a system designed to detect "hostile thoughts" in people walking through border posts, airports and public places. The DHS says recent tests prove it works.
'Pre-crime' detector shows promiseA 2005 DARPA report... proposes to "image through multiple walls and even penetrate whole buildings using distributed sensors on or around buildings," with UAVs assisting ground forces. A 2007 Army Research Lab study explores the ability of ground sensors, working with UAVs, to capture "images from different angles," thereby providing "intelligence on the configuration, content, and human presence inside enclosed areas (buildings)."

The device – dubbed MEDUSA (Mob Excess Deterrent Using Silent Audio) – exploits the microwave audio effect, in which short microwave pulses rapidly heat tissue, causing a shockwave inside the skull that can be detected by the ears. A series of pulses can be transmitted to produce recognisable sounds...
MEDUSA involves a microwave auditory effect "loud" enough to cause discomfort or even incapacitation. Sadovnik says that normal audio safety limits do not apply since the sound does not enter through the eardrums.

The blood was dribbling out of the corner of my mouth. "The artery's gone," I thought. I wondered how long you last when your carotid artery is cut; not many minutes, presumably. Everything was very blurry. There must have been about two minutes during which I assumed I was killed. And that too was interesting
