Good point. That was the biggest issue really, But as I recall the 9/11 commission concluded that the communications failures (aka withholding info) between FBI and NSA and FAA allowed the terrorist to board. This ultimately resulted in the creation of DHS and TSA to ensure a cohesive intelligence structure. Predictably, it has resulted in even more inter-agency competition and information hoarding. BTW, Lisa deserves the credit for making that piece readable. She did 90% of the work.
