'On the Saudi Trail of 9/11' (1/4). Omar al-Bayoumi denied being an extremist and a spy. Yet the jovial Saudi civil servant, who lived in the US before the attacks, was ever-present in the American journey of two of the terrorists. He even sometimes played paintball with a future leader of Al-Qaeda.
