I've been lurking for a long time on this board and decided to finally post here because because there is a lot of misinformation in the media about this subject. For anyone who really cares, I suggest the book "Why America Slept" by Gerald Posner. It came out in Oct. '03, months before male private part Clarke's. Posner is completely impartial in his investigation and has nothing to gain politically. There was tremendous incompetence on many levels of the govt.(INS,FBI,CIA,) dating back to the Reagan Adminisrtation. There were also many other political and social aspects aspects that contributed to 9/11. Posner also has an excellent book about the JFK assassination called "Case Closed" which is fascinating. He's also a UC Hastings law grad.
