The Pentagon seems mighty uneasy about going after some of its private contractors for the money they've skimmed over the years.
The Pentagon has done little to collect at least $100 million in overcharges paid in deals arranged by corrupt former officials of Kellogg Brown & Root, the defense contractor, even though the officials admitted much of the wrongdoing years ago, two senators have complained in a letter to Defense Secretary Robert M. Gates. ... Their letter is likely to revive allegations that the Pentagon has
become so close to KBR, and relies so heavily on it, that there is
little inclination or incentive to discipline the company, in response
to either Congress or critics outside the government.
In some cases, the overage paid by the taxpayer to corrupt subcontractors was as much as 76%.
