Here is a section from Part I of the 2004 Citizens' Complaint and Petition to Attorney General Spitzer citing probable cause for convening a grand jury or starting a criminal investigation into unsolved crimes relating to the events of Sept. 11th.
http://justicefor911.org/Part_I_Complaint_111904.phpI was the head writer on this, though not the final editorial authority. This passage describes the assumptions of the official story. It continues through other points that either need updating or are not as likely to have consensus here as accurate descriptions of the official story. One I find ill-advised today, as really it's a sarcastic editorial comment on my part: "No reports from foreign governments, agencies or news services alleging facts directly contradicting those set forth by official US sources need be examined or explored."
THE OFFICIAL STORY
5. All official investigations took for granted a certain set of a priori and unquestioned assumptions, which are summarized for your examination in the list below. These items constitute what has come to be called the "official story" of 9/11 as it was portrayed to the press and the people immediately after the attacks. But evidence presented elsewhere in this Complaint and Petition casts serious doubt on the veracity of the assumptions set forth in this list in the minds of many:
a. The 9/11 plotters intended to hijack no more than four planes, which were commandeered and flown by 19 Middle Eastern hijackers. Their identities were resolved conclusively in the hours and days immediately after the attacks and have never since been in doubt.<6>
b. The 9/11 plot was set into motion and financed by a network surrounding Osama bin Ladin, without direct financial backing from his wealthy family or other Saudi agents, and without the participation, involvement, accessorial conduct or knowledge of any states or state agents, either foreign or domestic, prior to or during the plot's execution.<7>
c. No US officials could possibly have had actionable foreknowledge of the plot, for if they did they "would have moved heaven and earth" to intervene.
d. Investigation into the actions and behavior of US government agents and Bush Administration officials could not possibly uncover any greater level of culpability than unintentional failures of intelligence, communication or surveillance, or at worst individual incompetence or negligence. And further, since any questions of foreknowledge, acquiescence, or accessorial criminality were never to be contemplated by the Kean Commission, its investigations could without difficulty be supervised by a former high-level adviser to the present Bush Administration—despite the obvious conflicts of interest of Executive Director Philip Zelikow, and virtually every other member of the Kean Commission (see, Appendix 6).
e. Suppression of relevant facts regarding 9/11 has been an undeniable necessity of national security; no elements within the US government or Administration would exercise pressure or influence<8> to avoid certain avenues of investigation or bodies of evidence in the probes carried out by the Justice Department, Congress, the National Institute for Standards and Technology ("NIST"), the Federal Emergency Management Agency ("FEMA"), the General Accounting Office, the CIA, and the Kean Commission.
