This document here gives a detailed log of how things unfolded in 2001 resulting in the supposed escape of Osama Bin Laden.
Are they true? Is Osama not dead? Was he not buried on the afghan mountains after the american carpet bombing? Don't ask me.
It has all the charactaristics like the eternal Netaji Subhash Chandra Bose type mystery. The only difference probably being that while Netaji is held in high esteem as a national hero and as one who cared for the people , the other is a dreaded islamic fundementalist who burns down buildings full of people without even blinking, in the name of religion.
