Ray,

You make reference to the Westerfield exam and the examination of (I believe) six others.  The one link I see to tapes begins with the poly question review with Westerfield (does not contain the other prior portions of the pre-test interview) and continues throughout his in-test phase and interrogation.  This (although better than many polygraphers do) is not a complete recording of all that took place with Westerfield and contains no information from the other six you claim to know something about.  If you can provide complete information, I will take the time to review the material.  Until then, my assessment remains as previously stated...
