George,

[code]Perhaps this block of instruction is so short (and included almost as an afterthought) because DoDPI has no reliable methodology for the detection of countermeasures.  [/code]

Perhaps you should tell the entire story and not put a Spin on the training.  I found this on the same DoDPI site you found the four hours of training on the last day of classes:

COUNTERMEASURES (40 CEH)
This 40-hour course prepares the PDD examiner to deter, detect, and prevent employment of polygraph countermeasures in criminal and intelligence testing environments. The course presents background information as a foundation, concepts, theories, and research data related to polygraph countermeasures. Laboratory exercises are included to enhance skills and provide hands-on experience. Detailed discussions of numerous case studies involving examples of confirmed countermeasures efforts targeting law enforcement and intelligence polygraph examinations are used to demonstrate methods of detecting and defeating this threat to law enforcement and intelligence polygraph operations. Information provided includes discussion of threats posed by foreign intelligence services, terrorist organizations, and other criminal elements attempting to defeat law enforcement and or intelligence polygraph examinations. This course is intended as the primary polygraph countermeasures course for criminal and security screening PDD examiners or as a periodic refresher course for examiners supporting intelligence operations. The course includes daily directed reading assignments followed by classroom discussions and quizzes.  Prerequisite: The student must be employed or contracted as a polygraph examiner by a federal law enforcement or counterintelligence agency.

I have said it before, I’ll say it again.... I may not be a big fan of the polygraph, but lets stop spinning the issues before you start to sound like a politician!
