Partly by fate: There is no way that such an event, held during an election year, can help but become hopelessly politicized.
Partly by design: instead of jurists, or law-enforcement people, or military types, or corporate-management gurus or specialists of any kind, it was formed exclusively of politicians.
Partly by stupidity: We now have found that one of the major problems was that the CIA and the FBI were not communicting as well as they could have. Of course, part of the reason that was so was because restricting was official policy as advocated by a member of the commission among others.
The end result is a public hearing in which the public is told to “stay out of our business” by the chairman.
The whole thing is a waste of time, sez I. We’ll know “the whole, true story of 9/11” in about 25 years.
