I dug out this old post by Bluecrab because Cleve Backster is mentioned in it. Backster is a famous polygraph expert. Does anyone know what ecaxtly Backster 'verified' here? Did he ask the Ramseys the same questions? Was he paid by them? And didn't the Ramseys refuse to take a polygraph test by the FBI? And didn't Patsy flunk a polygraph test (administered by Toriello) just prior to the test done by Gelb? Was it Gelb who agreed to test Patsy although she was full of tranquilizers which mute the body's response to stimuli? Isn't such a polygraph test totally worthless? I wonder if Backster knew that Patsy was full of sedatives.
