Once more, in an attempt to sensationalize a case for TV, the media has attempted to use a polygraph test for the show Inside Justice to investigate the conviction of Glyn Razzell. It seems his refusal to take a test has been taken as evidence of guilt. It should be noted that The U.K. prison service has banned the use of Polygraph within any of its facilities since 2015.
The Glyn Razzell case was examined by the BBC show, which apparently the convicted murderer had originally hoped would help him win an appeal.
The test was refused by Razzell on grounds that the tests were not reliable or had many false positives. In a last minute refusal of the polygraph test he called it “pseudo-science”. “I’m worried about a false positive. I don’t think it’s reliable. I just can’t see the benefit”, he said. What a shame.
We may never know now, but a polygraph test is extremely reliable and there is almost no possibility of a false positive. Of course, having an independent test by a well-known experienced examiner would help.
We would like to extend an invitation to Glyn Razzel to take an independent test in our offices. The results are highly accurate and we have no bias…or ratings to achieve. The majority of people we test are very nervous but a good examiner will work hard to relax the examinee in the pre-test interview, that can last up-to 2 hours. Fortunately a person’s nerves and anxiety on taking a test have no effect on the results…if it did everyone would fail a polygraph test.
