The Raw Story | PBS: NSA could have prevented 9/11 hijackings Author James Bamford looked into the performance of the NSA in his 2008 book, The Shadow Factory, and found that it had been closely monitoring the 9/11 hijackers as they moved freely around the United States and communicated with Osama bin Laden's operations center in Yemen. The NSA had even tapped bin Laden's satellite phone, starting in 1996. "The NSA never alerted any other agency that the terrorists were in the United States and moving across the country towards Washington," Bamford told PBS. so much for the "Nobody could've forseen th eevents of 9-11" BS military running excersices of hijacked airliners that day NSA had tabs on the hijackers Bin Laden's Phone tapped since 1996 PDB 'Bin Laden determined to strike within the US' Bush kept us safe????? what a joke.
