As for the government's use of polygraph, it seems clear that their security-oriented "war footing" mentality trumps concerns over collateral damage. For example, we see the same justification in drone strikes targeting high-value targets. Innocents are often sacrificed in order to get the bad guy. Save for the blood and guts, the same overall dynamics are at play in the gummint polygraph suite.

You are right on the money Dan.  Collateral damage has always been a part of war.  What is incredible in this case is that the collateral damage includes almost exclusively our heroes.  Imagine being in the trenches, being wounded, offering your life for your country, surviving, and then coming home to lose a job with the government you protected because of an "inconclusive" on a polygraph.   The above described situation has occurred and I personally know at least one of the people to whom it happened.  It is unconscionable.  I can not think of any other time in history that such horrific betrayal has occurred.   I've only seen it in James Bond movies when the bad guy sacrifices his loyal henchmen while calmly petting his cat.
