Justin,

This has got to be disinformation. If the FBI got it's hands on bin Laden's code books, that would be the most closely guarded national secret since the US cracked the Japanese codes. What their telegraphing to bin Laden's people through this disinformation is bin Laden's cells can't communicate by electronic means without us listening in. The truth is if bin Laden's mob had a brain cell (and for sure they do) then they are using the PGP (Pretty Good Privacy) encryption standard set with a 1024 bit key or better. Supposably not even the NSA can crack that (which is why the NSA did their best to suppress it).
