Disclaimer: This diary will posit no alternative explanation for the events of September 11, 2001.
It does recognize the recent work of the NY Times reporter and his book on the 9/11 commission. This diary also recognizes that Kean and Hamilton have distanced themselves from the reliability of military testimony about which they considered pressing charges. Large redacted sections dealing with one country are enough of an indication that the results of the investigation are motivated by political considerations more than by the awful necessity of the full truth.
The most widely accepted narrative and analysis of the events of September 11, 2001 is a conspiracy theory that has never been adequate.
While extreme and unreasonable claims have been made by many hypothesists the most important and valuable reply to those hypothesists is a full and fair re-investigation of the events by irreproachable individuals free of "intelligence agency", foreign policy and international political attachements.
