According to CBS News, in the afternoon before the attack, “alarm bells were sounding over unusual trading in the US stock options market.” It has been documented that the CIA, the Mossad and many other intelligence agencies monitor stock trading in real time using highly advanced programs such as Promis. Both the FBI and the Justice Department have confirmed the use of such programs for US intelligence gathering through at least this summer. This would confirm that CIA should have had additional advance warning of imminent attacks against American and United Airlines planes. [CBS, 9/19/01] There are even allegations that bin Laden was able to get a copy of Promis. [Fox News, 10/16/01] [FTW]
