*At a government workshop some time ago I head someone describe a new tool that was described as the “voice of Allah.” This was said to be a device that would operate at a distance and would deliver a message that only a single person could hear. The story was that it was tested in a conflict situation in Iraq and pointed at one insurgent in a group, who whipped around looking in all directions, and began a heated conversation with his compatriots, who did not hear the message. At the time I greeted this story with some skepticism. *
