Anti-polygraph has some good stuff, but its written with an agenda. We can't use a poly results as the "matter of record". What it is used for, just like law enforcement, is to develop leads. I would never determine someone’s fate on the results of a poly. OJ Simpson had a poly and one of my former instructors sat in for the State of California. The poly was set up by the defense team. OJ was asked all of these "round about " questions that were never very direct. The whole point by the defense was to introduce the poly as a means to show non-conclusive results, which is not innocence. My former instructor was there so he could testify for the state. The polygrapher, paid by the defense, never once asked "Did you kill your wife" or "Did you kill Ron Goldman". Questions were framed as "were you involved in the conspiracy to kill these two people". No conspiracy and what two people? Results could get a inconclusive or negative response. Why you can't use them as prosecutorial evidence in most courts.....
