That this example proves anything
A report comes out saying that government spending is out of control. Everyone gets their panties in a twist.
A followup comes out saying no, the previous report was incomplete. Now you're saying both spending
and auditing "can't be trusted".
An auditor's role is to find things that seem wrong and ask about them. Sometimes there are good reasons for things to be exactly as they are. This was one of those cases.
Both procurement and auditing worked exactly as they're supposed to. Well ... except that someone took a line from an audit and turned it into a manufactured scandal. This incident doesn't prove
anything about procurement or auditing practices.
PS:
The bottom line: A mountain of treats can get pricey. In 2008-2009, the Justice Dept. alone held 1,832 conferences costing a total of $121 million.
That's not the bottom line. The bottom line is that we just spent a few days arguing about a manufactured scandal relating to 0.000000000011% of the federal budget.
