Polygraph examiners can and in many circumstances do provide the conclusion to the examination.  My experience is proof of such a transgression.  If you grill someone for 15-20 minutes on a particular topic you will definately see a response to the topic.  Paul R. (I hope you are reading this) knows such is the case as he readily admits to conducting all his exams as he conducted mine by pre-determining the outcome (why don't you come clean and admit it to your contemporaries you liar).  My opinion is that your examiner took one look at you, decided that you didn't have "the right stuff" and made a decision for his agency...ridiculous.
