I recently had the misfortune to read Spying Blind: The CIA, the FBI, and the Origins of 9/11 by Amy Zegart. I have to say it is the very worst book I have ever read abut 9/11. It was even worse than this one, which, as you can appreciate, is difficult, and it was way, way worse than this one, this one and this FBI press release. I haven’t read this one yet, and I anticipate it will be a lot, lot worse even than Zegart’s attempt, but you never know.
Basically, Zegart takes the 9/11 Commission’s no-fault thesis to the nth degree by claiming the whole thing was systemic failure and holding no individual accountable for his or her failures.
