Elahi's site is the perfect alibi. Or an audacious art project. Or both. The Bangladeshi-born American says the US government mistakenly listed him on its terrorist watch list — and once you're on, it's hard to get off. To convince the Feds of his innocence, Elahi has made his life an open book. Whenever they want, officials can go to his site and see where he is and what he's doing. Indeed, his server logs show hits from the Pentagon, the Secretary of Defense, and the Executive Office of the President, among others.
