And neither can you......
It was a MAJOR intelligence failure inside the US.
During the time PRIOR to 9/11, someone in Washington was giving the FBI orders to IGNORE all Al Queda members who were trying to fly planes at flight schools here in the US. The top FBI official in Washington who denied frequent requests to monitor Mousssi'a computer, was given a raise and PROMOTED after 9/11, while Bush & Co. still block the investigation and remove pertinent, well known facts from the investigation.
