I recently took my poly for a local LE. It went exactly as I thought it would. He gave me the whole deal how it works and how it is impossible to be deceptive. I filled out a lengthy questionaire and he asked me about a few minor things that weren't to serious. He asked me 3 sets of questions twice. In between sets he asked me if I knew anyone who sold drugs. I gave him an honest answer and he seemed to accept it. When I was done he said I had "good charts" and to keep going to my local LE meetings. I didn't ask him if I passed, he said he would send my results to a review board and I would receive a letter in the mail in a few weeks. This would say either no thanks or you will be contacted by a background investigator. He was pleasant the entire time and shook my hand after the test was complete. There was no post interview. He said he hoped to see me in the future as well. Did I pass or what. I thought it went ok, but who knows. He told me I had good charts a few times.
It looks like you did pass your polygraph exam. If you failed it, the person that administered the exam would have confronted you on it. There are posts throughout this message board that can confirm what I said, look them up...
