Read bits and pieces. Contradicting positions taken by the author. First, it is suggested that the US might attack itself. Then it is suggested that Al Qaeda was "allowed" to attack the US. Then there seems to be complaint that everyone was ignoring the warning signs. If they knew Al Qaeda was going to attack, wouldn't they have wanted to at least present the appearance of anti-terror vigilance? Like I said, scanned it briefly, maybe I missed the point.
