Hand-held Lie Detector For U.S. Military
A hand-held lie detector is being deployed by the U.S. Department of Defense according to a report in 2008 by investigative reporter Bill Dedman of msnbc.com. The Preliminary Credibility Assessment Screening System, or PCASS, captures less physiological information than a polygraph, and uses an algorithm, not the judgment of a polygraph examiner, to render a decision whether it believes the person is being deceptive or not. The device will be used first in Afghanistan by U.S. Army troops. The Department of Defense ordered to limit its use to non-U.S. persons, in overseas locations only.

Famous quotes containing the words lie and/or military:
“Some collaboration has to take place in the mind between the woman and the man before the art of creation can be accomplished. Some marriage of opposites has to be consummated. The whole of the mind must lie wide open if we are to get the sense that the writer is communicating his experience with perfect fullness.”
—Virginia Woolf (1882–1941)
“Personal prudence, even when dictated by quite other than selfish considerations, surely is no special virtue in a military man; while an excessive love of glory, impassioning a less burning impulse, the honest sense of duty, is the first.”
—Herman Melville (1819–1891)
