A mainstream news story about the CIA deciding not to pursue the 9/11 hijackers despite serious warning from the FBI. While shrugging off deeper skepticism, this story does promote interest in the facts surrounding the attacks. 9/11 truth advocates may view this as limited hangout journalism that is intended to cover more disturbing facts, however any mainstream coverage for the facts serves to promote an acceptance of curiosity into the event.
The NSA failed to pass on information about the hijackers, perhaps deliberately to aid CIA machinations, and has not even stated publicly whether and how it investigated this failure, let alone what the conclusions of such inquiry might be. Nevertheless, with remarkable speed it used its failure as a justification for massive new powers. This is just one of the legacies of 9/11.
