Stefano, You are using the same tactic you accuse polygraph examiners of using.  If the CM did not work, you used them incorrectly.  (If you passed while using CM the examiner was not properly trained.)  Why not just admit CM's are detectable unless you have had EXTENSIVE training in their usage.

How about because the countermeasures as presented in The Lie Behind The Lie Detector ARE NOT detectable? I've read the book twice and employed the countermeasures (successfully) numerous times.

Why not just admit polygraphs don't work, have no scientific basis, and shouldn't be used at all?
