1) As the NYT reported Saturday, $300 million cash from Iraqi gov't coffers has gone AWOL. Iraqi officials say was shipped to Lebanon as payment for old tanks and such from arms dealers. (That should make you feel better.)
2) A U.S. contractor, and his Iraqi translator, were killed after the contractor complained about corruption in the Iraqi defense ministry.
3) As the Financial Times reported last month, the Iraqi gov't transfered $400 million of the food-ration budget to Lebanese banks, which happen to have generous secrecy provisions.
4) (bonus example): The current gas shortage crisis.
Last spring, the radio program did an excellent series on corruption in Iraq. Perhaps somebody would like to do a big followup?
