Going to an anti-war demonstration? Be sure to wear Mylar.

The Pentagon's new "crowd control" microwave weapon, developed by the Defense Advanced Research Projects Agency (DARPA) was tested on January 24, 2007, as a pointed reminder -- and warning -- to would be participants in the anti-war demonstration in Washington, D.C. on January 27.

The weapon, nicknamed "Sheriff" and called Active Denial System (ADS), was mounted on a Humvee and shown to the media at Moody Air Force Base in Georgia.

The allegedly "non-lethal" weapon, developed by Raytheon, uses a directed energy beam emitting from a parabolic antenna and aimed at so-called "angry mob" or "rioters."

The weapon heats the skin of the targeted individuals to 130 degrees, giving them the perception that they are being burned alive.

The problem with the government/media promoted weapon, reports independent journalist Wayne Madsen, is that it can be defeated by using aluminum- or gold-coated Mylar to deflect the energy beam back to the Humvee from which it came.
