Getting back to taping the poly:

My poly was taped, but I assume the gov.  isn't just going to turn over my video/audio tape on which the polygrapher explicitly states that I passed the test.  The tape would only prove that I had in fact passed the poly, however, having quota's for underrepresented people is more important than fairness.  Taping poly's (or allowing tapes to be released) would only show the true absurdity of the "lie detector."
