quickfix: you are confusing "entitlement" with "right." Yes, no one is entitled to a government job or a security clearance, but the applicant has the right to be rationally evaluated for the position. If you allow the use of junk science polygraphy, why not employ voice stress, astrology or palmistry?  The CVSA has been advertised as being 1/3 cheaper than the polygraph.  Maybe the positions of the planets and stars at the time of the applicant's birth to determine eligibility for employment and clearance.  Just think of all the potential savings of money if background investigations were to be eliminated.

In my own experiences, at least, there was certainly no such rational decision-making.  Getting through the BI appears to me to be entirely a matter of chance and luck (which in my case was lacking), not at all related to the applicant's qualifications or abilities! >:(
