FP Editor-in-Chief Moisès Naím explains:

At first sight, the scandals that brought down Eliot Spitzer, the former governor of New York, and Klaus Zumwinkel, the former president of Deutsche Post (the German corporate behemoth), didn't seem to have much in common. Spitzer fell two weeks ago for hiring prostitutes; Zumwinkel, two weeks before that, for tax evasion. Yet there's a thread that binds them together: money laundering. Both men were brought down by a new system for tracking money that was created in reaction to the 9/11 terrorist attacks—but that has since spread its net far beyond jihadists.
