Lecture on 9/11 by Christian Theologian David Ray Griffin

I attended a lecture tonight at the UW-Madison campus by Christian theologian David Ray Griffin. This is the author of "The New Pearl Harbor – Disturbing Questions about the Bush Administration and 9/11". His most recent book is "The 9/11 Commission Report: Omissions and Distortions". The title speaks for itself
The lecture this evening was reported to be the first of its kind - the first time a formal lecture has challenged the official 9/11 story. In addition, it was being recorded for broadcast on C-SPAN! The lecture was entitled "9/11 and the American Empire: How Should Religious People Respond?" He started off with some definitions of "religious people" (apparently Christianity isn't the only religion), and "American Empire" - the conservatives would have you believe America is the world's first "benign" empire, but I think the point is pretty debatable. Then he gets into the heart of the lecture with a discussion of 9/11. He categorizes people into 4 groups:
1. People who believe the official story that the 9/11 attacks were a surprise attack orchestrated by 19 Islamic Al-Qaeda terrorists.
2. People who believe 9/11 was used opportunistically by the Bush administration to advance an agenda
3. People who believe that the Bush administration had foreknowledge of the attacks but did not stop nor prevent them. No national polls have been taken, but one Zogby poll in New York City showed 50% of the people thought Bush knew.
