How bin Laden emailed without being detected

Regardless of having no Internet access, Bin Ladin was a profilic email writer who built a painstaking system that kept him one step ahead of the U.S. government's best eavesdroppers. His methods, described in new detail to The Associated Press by a counter terrorism official and a second person briefed on the U.S. investigation, served him well for years and frustrated Western efforts to trace him through cyberspace. The arrangement allowed bin Laden to stay in touch worldwide without leaving any digital fingerprints behind. The people spoke to the AP on condition of anonymity to discuss the sensitive intelligence analysis.
Bin Laden's system was built on discipline and trust. But it also left behind an extensive archive of email exchanges for the U.S. to scour. The trove of electronic records pulled out of his compound after he was killed last week is revealing thousands of messages and potentially hundreds of email addresses, the AP has learned.Holed up in his walled compound in northeast Pakistan with no phone or Internet capabilities, bin Laden would type a message on his computer without an Internet connection, then save it using a thumb-sized flash drive. He then passed the flash drive to a trusted courier, who would head for a distant Internet cafe.At that location, the courier would plug the memory drive into a computer, copy bin Laden's message into an email and send it. Reversing the process, the courier would copy any incoming email to the flash drive and return to the compound, where bin Laden would read his messages offline.

My Opinion :

All i can say is wow! This completely amazes me in two ways. First I can't believe that Osama would come up with something like this which truly proves his true self and how he really is such a bad person. Secondly it reveals flaws in the U.S government and how they wouldn't think of this before him or be able to detect it. The process completely amazes me, and also Osama's desperation is quite disturbing. None the less, at least we found out what he was doing and in the future we will no better to detect it.
