....in the wake of the incredibly stupid photo op flyover Lower Manhattan, Obama accepted the resignation of Louis Caldera, WH Military Office director (former secy of the Army). As government foul-ups go, this one was pretty monumental. ....the incident cost taxpayers $357,00 and panicked 1000's of New Yorkers haunted by 9/11.......but who came up with the nutty idea? The Pentagon is undertaking a review -- Deputy White House COS Jim Messina says he didn't know until the flyover had taken place......where should the buck stop? Alas, that remains a mystery.
