Great article, thanks for sharing.  It is obvious that the polygraphist Kevin was failing as many people as possible to lessen the chance of having another embarrassment like the Aldrich Ames case.  The game is to flunk as many as possible.  If it turns out the individuals were not lying, the polygraphist can blame the tested people for attempting to use counter measures, such as fast or slow breathing, muscle tightening, etc.
One problem we have in the law enforcement community in general is the shortage of operatives.  The lie community is putting public safety at risk with their pseudo-science careerism and game playing.  We need boots on the ground and keeping capable people out of public service careers is already having serious repercussions on public safety. Again, polygraphists and voice stress analysts must stop putting their careerism ahead of the safety of America.
