I've grown curious regarding the use of the polygraph in the case of convicted cop killer Mumia Abu Jamal. He has been the subject of a tremendous amount of misleading propaganda, including an incident in which a self-described professional hit man came forward, many years after the conviction, with an obviously fabricated confession claiming he did the crime, not the convicted who was seen by many highly credible witnesses and who was arrested at the scene with the murder weapon registered to him. 

Various news reports claim that the person making the confession "passed a lie detector test." Supporters of the convicted killer now claim that test exonerates their man.  The "confession" was rejected out of hand, even by the original defense lawyers and eventually by the courts.  Yet there is this claim, that I can't substantiate or refute, that a polygraph test supports the confession. 

Can anyone either provide me with detailed factual evidence of that such a  test event actually did take place (a transcript, a polygraph operator's report of the event, etc.)?   I've written to the man (Charles Hont) who suposedly administered the test but I have not yet had a reply. 

I'd also welcome guidance on the subject of admissability of polygraphs in capital cases in the State of Pennsylvania where the murder took place. 

Thanks, curiousjoe
