George, none of these polygraphers will ever rise to the challenge.  The main reason is that they KNOW they lack the ability to detect countermeasure use even a third of the time.  They have to remain with their song about how they can or they would quite possibly be out of a job.  Personally I cannot see why anybody would put any faith in this practice to begin with, and even more I find it repulsive that polygraphers are so unrealistic to believe this trash they practice really works.
