I read a lot of places that a high percentage of people in the US believe that President Bush was somehow responsible for the 911 attacks. I saw one fellow on TV who was identified as some sort of college prof who said he was certain that Bush did it, but he didn't know how it was done. There are always a lot of conpiracy theorists after an event like 911. I've read that perhaps 15-20% of Americans don't believe that men have gone to the moon. A few years ago many people thought an errant missile from a US Navy ship brought down a commercial airliner. There are still many who don't believe that Oswald shot President Kennedy. I saw one fellow on TV who thught hundreds of people were involved in the Kennedy assasination. That is one of the flaws in most conspiracy theories. As the event is investigated in a rational manner more and more people have to be involved to support the theory. But experience shows that it is difficult to keep a secret, and the more people that are involved, the more difficult it is to keep something secret.
