I watched an interesting NOVA two days ago about the NSA and 9/11. It described the NSA and their role in the events that led up to the tragedy. I urge anyone that is just curious to look it up on the NOVA site. It sheds some light on some information that you might not know. It made me angry when I saw the show, because there was knowledge about these terrorists - they were being monitored for three years prior to the disaster and up until the day before the tragedy occurred. They showed the record of phone calls back to OSB's terrorist HQ and a record of where they shopped, what they bought, what flight training they took, and even a speeding ticked they received on their way to NJ. They didn't even have aliases while they were in the US - they operated under their real names - received VISAs etc.etc. Now when the 9/11 commission questioned the head of NSA he cited that due to the laws of the time one could not infringe on the rights of a person legally here on US soil (like listening in on conversations, detaining at airports and the like) The sad thing is that in all honesty this could have been prevented had the govt agencies coordinated their info or just spoke up about bad guys being on our turf (as one FBI agent said).
