DIA Polygraph Countermeasure Case Files Leaked

George Maschke writes AntiPolygraph.org (of which I am a co-founder) has published a set of leaked Defense Intelligence Agency polygraph countermeasure case files along with a case-by-case analysis. The case files, which include polygraph charts and the exact questions used, suggest that the only people being "caught" trying to beat the polygraph are those using crude, unsophisticated methods that anyone who actually understood polygraph procedure and effective countermeasures (like, say, a real spy, saboteur, or terrorist) would ever use. AntiPolygraph.org has previously published polygraph community training materials on countermeasures that indicate they lack the ability to detect countermeasures like those described in our free book, The Lie Behind the Lie Detector (PDF) or in former police polygraph examiner Doug Williams' manual, How to Sting the Polygraph. Williams, who was indicted last year after teaching undercover federal agents how to pass a polygraph, is scheduled to stand trial on May 12 in Oklahoma City.

If Polygraphs are infallible

Then why is someone on trial for teaching how to beat them? Makes no sense, unless they are beatable, in which case they are only security by obscurity - aka useless against a real threat.
