On the one hand, Lance's book presents us with useful information, he has revealed more about Ali Mohamed than anybody else. Other books on 9/11 tend to skip Mohamed, or give him a quick bio, excluding his links to the FBI, the CIA, and the US Army.. But Lance actively encourages us to believe that despite the fact that Mohamed had far more provable links to the US intelligence and defence establishments than he did to the establishment version of "al Qaeda"; he wants us to believe that Mohamed was a crypto-agent for Osama bin Laden, that "al Qaeda" is a "top down" crack team of efficient terrorists, in spite of flagrant violations of the "top down" scenario, like, for example, Laui Sakra.

So I wouldn't dismiss out of hand the idea that Lance's book has proportionate amounts of bullshit mixed in with the good stuff. And of course, reading Lance's work, (as well Wright, Coll, et al.), it's impossible to say that these books are written objectively. They are written with the a priori assumption that the establishment version of "al Qaeda" did 9/11, with no critical reflections on the truth of the matter.

Let's see what Peter Dale Scott says of Fitz;

The 9/11 Report mentioned [Mohamed], and said that the plotters against the U.S. Embassy in Kenya were “led” (their word) by Ali Mohamed. That’s the Report’s only reference to him, though it’s not all they heard.

Patrick Fitzgerald, U.S. Attorney who negotiated a plea bargain and confession from Ali Mohamed, said this in testimony to the Commission

Ali Mohamed. …. trained most of al Qaeda’s top leadership – including Bin Laden and Zawahiri – and most of al Qaeda’s top trainers. He gave some training to persons who would later carry out the 1993 World Trade Center bombing…. From 1994 until his arrest in 1998, he lived as an American citizen in California, applying for jobs as an FBI translator.

Patrick Fitzgerald knew Ali Mohamed well. In 1994 he had named him as an unindicted co-conspirator in the New York landmarks case, yet allowed him to remain free. This was because, as Fitzgerald knew, Ali Mohamed was an FBI informant, from at least 1993 and maybe 1989. Thus, from 1994 “until his arrest in 1998 [by which time the 9/11 plot was well under way], Mohamed shuttled between California, Afghanistan, Kenya, Somalia and at least a dozen other countries.” ...

...Let me say this again: one of al-Qaeda’s top trainers in terrorism and how to hijack airplanes was an operative for FBI, CIA, and the Army.

I can see why "the establishment" would want Lance's book(s) to go away.

Was the connection between Ali Mohamed and Khalid al-Mihdhar the reason that the CIA working with FBI HQ units that they had subjugated, the reason CIA deputy chief of the Bin Laden unit, Tom Wilshire blocked FBI Agent Doug Miller's cable on Mihdhar from going to the FBI criminal investigators on January 5, 2000? Both Mohamed and Mihdhar and worked closely together on the east Africa bombing attacks, and exposing Mihdhar would have ultimately exposed Mohamed to unwanted publicity.

Was this also the reason that the CIA and the FBI HQ units with held all information on the Kuala Lumpur meeting with Nawaf al-Hazmi and Walid Bin Attash from these same FBI investigators on the Cole bombing even though they all knew the planning of this bombing had actually taken place at this meeting. This was the speculation the author of “Prior Knowledge of 9/11”, now the most complete book on the events prior to 9/11, had reached for the possible explanation why both the CIA and FBI HQ had hidden all of this information from these FBI investigators, even when they knew by doing this thousands of Americans were going to perish in a huge al Qaeda attack as a result of their actions.
