My cousin is out there this week testing for them.  I work for a department in Utah and have tried to help my him prepare for our testing process, but he wants to be with a department with a little more action. One of our friends was dq'ed by them a little over a year ago because of his polygraph.  He has lived a very clean life and has never been in any trouble with the law.  He was very upset when it happened.                   He has since been picked up by a medium sized department in Arizona, and he is doing well.   Its really nuts how lie detector tests mess up so many peoples' lives.  I know that LVMPD does their polygraphs before any sort of background check.  I think it should be the other way around.  Better yet, take away the polygraph altogether.
