I think if there were any significant evidence that the USG under BUSH/CHENEY helped orchestrate, or even intentionally allowed 9/11, Obama would pounce on it. What better way to show he is truly about change, then to have a president and his VP impeached and charged with war crimes.
Obama, part of the US governing elite, is backing the biggest looting operation of our age. What makes you think he'd be interested in bringing rich and powerful criminals and friends to justice and possibly getting them executed?
