I agree with Marie's take on this, but I'm linking Jeremy's version because its not a PDF. Its well understood that this information was available before 9/11. Drastic changes to the makeup of institutions we not called for. Existing security mechanisms had worked prior to that point. The biggest red herring was the 1993 WTC bombing. Did they make organizational changes then to address the fact that they didn't predict that. Also, the embassy bombings and the U.S.S. Cole. Why didn't they foresee these things. Were they repairing that problem?

These, of course, are questions for the Clinton Administration... Also, there are questions that we should have been asking then, and not now, when we were busy fussing about interns.
