Witness where? Jeremy took the test after his conviction and this guy hasn't been a witness. However, it's a FACT that the test measures STRESS levels and is incorrectly referred to as a 'Lie Detector Test' so I am not incorrect in stating that HE is incorrect if he is claiming it PROVES Jeremy isn't lying.
Yes, you are incorrect...
It is irrelevant that he took the polygraph test after he was convicted, and the person who asked the questions and who recorded Jeremy's answers was and is an expert in his own right. He is what they call 'an expert witness', who can testify in criminal proceedings of his findings which arose out of the testing of Jeremy Bamber. His findings are admissible, and as a matter of law, must be accepted, unless a different expert who specialises in that field of expertise provides a conflicting interpretation from the same set of questions, answers and recording captured on various equipment. There is nothing to stop someone who is due to stand trial, from taking a polygraph test before the trial begins, and the results being tendered in as part of the defendants case. In much the same way that the results of a breatholiser or a drugs test can be tended and relied upon...
