So, it turns out that General McChrystal did nothing wrong after all. At least according to a Defense Department investigation. Rolling Stone magazine apparently refused to speak with the investigators.
From CNN.com:
Gen. Stanley McChrystal lost his job when Rolling Stone magazine ran an article in which some of his aides made disparaging remarks about the vice president and others. But a newly released investigation by the Department of Defense inspector general finds neither McChrystal nor any of his aides did anything wrong.
