Years ago back in the 90's I took a polygraph to prove m innocence in a series of thefts I was involved in. I was involved and I was young and very stupid then. I didn't know the laws regarding it then, I had no attorney or anything. I took the test and was just as shocked as the poly test giver when he informed me that I passed. I lied through my teeth. I have no idea what I did to pass it. Other than blind luck. So if a know nothing little thief can pass while lying, and they arent even admissable, then why are they even used?
