In February I secured permission to enter Osama bin Laden's compound in the northern Pakistani city of Abbottabad, where he was killed and where he had lived for the last half-decade of his life; the first, and only, journalist to do so.

I stepped into the bedroom where he was killed and looked up at the ceiling, where you could still see the patterns of blood that had spurted from bin Laden's head when the bullet fired by a U.S. Navy SEAL tore through the terrorist leader's face.

Most Muslims don't want to live in some Taliban-style utopia, which is what bin Laden and allied groups are offering.

And in the end, bin Laden died in a squalid suburban compound surrounded by his wives and children and far from the front lines of his holy war.

Bin Laden comes out of a business background - he studied public administration and economics at university, and he worked for his family company, which was obviously a rather successful enterprise.
