I had a chance to try out a similar device. There were problems with noise and false positives. Wearing it around the house I got a lot of false positives after my mom had gone to bed and my dad got ready to call it a night. I seemed to get threat readings even from the near subliminal sounds he made. It was quite distracting. She's much too good for him. Also, outdoors, flamboyantly dressed men displaying dramatic body language seemed to push threat reaction into the red zone.

A schism erupted between specific threats and more general, almost, archetypal threats. Generally I found if I just forcefully asserted my will most of the threats seem to disappear.

Of course with the DARPA stuff there are protocol issues when the soldiers network and the stuff seems not to scale well.

What would the computer pick up, if it could scan a soldier's mind? Especially if the soldier is not thinking about soldiering? Would the central command computer be filled with images of cigarettes, curry, purloined toilet paper, and naked women? We should be told.

So they are working on Helm huh? When will we see Bagman and Gunnar going into action...?
