I think this may be a better link for the facts.
I don't believe in fortune tellers.
I do believe many in the Muslim community were warned in advance by fellow Muslims that knew there would be an attack and the adults remained silent. The silence of those that knew in advance now bonds them with those that wish to destroy us.
Is it possible that some Muslim knew in advance the attack were going to happen? Sure. But I think the search for those people would be helped if people actually had some concrete evidence instead of just posting variations on urban legends and things they heard on talk radio or from a "friend of a friend".
