After studying the email exchanges between Doug Williams and Gordon Barland, I have been entertaining a particular wonderment...

Will any elder statesmen of polygraph ever muster the courage to tell the truth -- in a highly public way -- about the true-life risks, realities and limitations of the "test" before they shed their mortal coil?

Such insider revelations could go a long way in helping to right the wrongs that have long plagued polygraph.
