If you're looking for a reason to lash out at the government, but are hesitant to visit WikiLeaks for fear of Joe Lieberman's wrath, check out the Commission on Wartime Contracting in Iraq and Afghanistan webpage. This bipartisan legislative commission released a report in June of 2009 which is chock-full of sickening information.
There are $13 billion dollars in "questioned" or "unsupported" costs, but don't be too concerned. The vast majority of these costs are linked to the former Halliburton subsidiary KBR. I'm sure they are honest mistakes.
If you want to help the government help Halliburton you can make a contribution to the National Debt which is currently $13, 843, 457, 556, 754. 48. Don't worry, your part of the tab is only $44,710.34.
