I originally took a polygraph exam to get on a state police department.  I went in not knowing anything about polygraphs.  I told this clown everything!!  Then, afterwards he asks me "did any of these questions bother you?"  I told him know and he then grilled me and told me I "showed something" on the question "other than what you've told me, have you ever committed a crime?"  I answered "no" with a clear conscious.  He then asked me if I would be willing to take it later with someone else "if they want you back".   

So I just took the "re-test" a couple of hours ago.  Only this time, armed with the knowledge of THE LIE BEHIND THE LIE DETECTOR.  I asked the new detective why I would "pass" questions like "are you delibertly lying to me" and "have you lied or ommitted anything about crimes you've been involved in?" but I "failed" the question "other than what you've told me, have you ever committed a crime"?  I didn't really get a clean response.  More dancing than at a wedding.

Anyway, I felt really confident this time after reading up on this website and passed with no problem.  I suggest anyone going in for a polygraph read THE LIE BEHIND THE LIE DETECTOR.  I clearly was incharge, not the examiner.  Knowing how they work put my mind at ease.  I wasn't trying to lie on this exam, just pass..  Beware of trickery and deception by the EXAMINER!

thanks a million
