All of this 9/11 commission nonsense is pointless. They're asking the wrong questions. We know how it happened... intelligence failure and a lack of communication between different agencies.
The real question people should be asking is why it happened. Two and a half years of Bush's bullshit "they hate freedom" crap is getting old. Obviously people hate us, and there's a good chance it has to do with what we did or didn't do in terms of global affairs.
When will someone ask those questions?
