You scroll down and they have surveillance footage of Atta at Portland International Jetport. It's dated too. There's footage of him in Portland but not in Boston. Why would this be? If there was footage of him in Boston, you'd think they'd show us the footage. Of course they could fix a video tape. With modern technology you're in a no-win situation. In one of his books David Ray Griffin asked something like 60-80 questions. It's a lot more than just the lack of surveillance footage that I have issues with. It's many, many different issues rolled into one that lead me to believe there's a 99% chance it was an inside job.
If you're a society that openly debates history which shows you have nothing to hide, conspiracy theories are likely to be false. If you're a society that refuses to debate history and shows it has something to hide, conspiracy theories are much more likely to be true. [bold]The United States is obviously much more the latter. [/bold]There are obvious reasons why many Americans believe conspiracy theories and the reasons make sense.
