US Deploys and Recalls 'Pain Ray'

As reported in this article by Al Jazeera, check out this $120 million 'pain ray' deployed to Afghanistan, and then immediately recalled as, not surprisingly, a PR disaster.  I'm not arguing that pain rays are evil while water cannons, flash-bangs and tear gas are good, but people are very easily frightened by things they don't understand.  I can see how a pain ray, packaged in an camouflaged truck with a big satellite-dishy thing on top, would be super juicy low-hanging fruit for Taliban propagandists to make America look like an even greater Satan.
