Thanks for changing your earlier post, Al. My answer still fits.

Spying Blind by Amy B. Zegert:
Publisher Princeton Press said:In this pathbreaking book, Amy Zegart provides the first scholarly examination of the intelligence failures that preceded September 11. Until now, those failures have been attributed largely to individual mistakes. But Zegart shows how and why the intelligence system itself left us vulnerable.
Amy B. Zegart is associate professor of public policy at the University of California, Los Angeles. She is the author of Flawed by Design: The Evolution of the CIA, JCS, and NSC.
Christopher Dickey said:Ever since the end of the cold war, the Central Intelligence Agency, the Federal Bureau of Investigation, the National Security Agency, and more than a dozen other intelligence organizations that answer to the president had been struggling to adapt their sources and methods to the new menace. As Amy B. Zegart argues in Spying Blind, they just weren't up to the job.... Zegart, blaming institutional inertia more than individuals, counts more than 20 specific instances where the CIA or the FBI missed chances to stop the 9/11 attacks.
Thomas Kean said:There is no longer any doubt of the failure of our intelligence agencies in the years following the Cold War. Amy Zegart has examined the reasons for this failure in addition to the well-meaning but mistaken attempts to address the problem. An important book for all those interested in the nation's security.
Lee Hamilton said:Spying Blind is a timely and sweeping overview of the organizational challenges confronting our intelligence agencies in an age of terrorism. Amy Zegart has written a comprehensive and engaging book that will be of interest to anyone who seeks a better understanding of America's national-security agencies.
