I'm surprised at the lack of discussion regarding the Westerfield polygraph.  That may be due to the fact that the case bodes well for polygraph.  According to what I've read, several "suspects" in the case were polygraphed.  Westerfield failed, everyone else passed.  This sounds like more than chance to me.  You can quote lab studies all that you want, but these seem like compelling real world results.  Also, in reviewing the tapes of the polygraph, I found the examiner to be very professional.  He didn't seem anything like the monsters you make examiners out to be.  George I'm curious to hear what you have to say about this.
