sosdd, if you truly don't believe any of these "success stories", you are an absolutely ignorant individual.  Any person with a shred of itellect and common sense would easily understand that the polygraph is so very unworthy of detecting lies.  Without instilling fear in an examinee's mind, which could lead to a confession, there is no way the polygraph could possiby be responsible for detecting deception. I find it ironic how the CVSA people and the polygraph people denounce one another, when in fact they are both a load of crap.  In fact these devices are no more than props used by interrogators.  However, if I spent a few weeks learning my "trade", I would defend it as well.  How many other careers that require so little to be certified are taken seriously.
