It sounds to me as if two soldiers in their bunkers, should think about
eating a little crow and apologizing to Terry Hallinan. The critics of the
media even use the world cruel, but since cruel is an adjective, hoax may be
implied. The hoax was not from the researchers, but from the media...a
deliberate attempt to deceive. Ron
