I totally agree with Luke hunter. He is correct about everything, as I had the same exact experience. I later found his poly graph results to be incorrect. We come to something like this as our last result, not to be lied to and mislead all over again. Stay away from this place. Save yourself grief.

You are asked to write down the questions you want asked. Be specific.
When he then wants to rewrite them say NO. Use your questions.
He says the quilt will set in and the questions do not need to be specific how wrong he is. Before going make sure you see his rewrites before meeting in the room. That way you have time to see what has been changed.
Fact the person was caught in the lie before the test. That person admitted they lied before the test. That question was part of my questions. He recommended his changes. To have a boarder type question because it did not need to be specific according to the tester. Well that person seemed to pass even though they where caught in the lie and that person admitted to it. When confronting the tester how is this possible to pass even though they admitted they lied. His response YOU NEVER ASKED THAT QUESTION. "Really" The tester also likes to give his advise on the situation. He should not be playing psychiatry since he is not licensed. In my opinion he is playing judge and jury and never shows the graphs. Be aware if you need this service. I would recommend using a different company that asks the questions you choose and does not want to change the wording or give you their opinion on what is right or wrong for your situation. Clearly he becomes bias. Find another service that keeps their personal views out of the situation.
