I've seen F911 and her observations are accurate, she may be 17 or 70 but she wrote a very good, well referenced and straight forward article - which is much more than you can say about f911.
Let me ask you this, is it reasonable to think that CNN changed their story just because FoxNews says something? Because thats exactl what Moore suggests in the movie. In other words thats what he expects his audience to believe after the movie.
