I don't think that Bush will be killed. I think he could be shot, leading to a whole new batch of alarmist legislation and things like 'put saran wrap on your house to protect yourself!'
That said, I've looked into a lot of what CRXForum is saying, and honestly, the conspiracy theorists suspend my disbelief a lot better and factually than the official government line. That's saying something.
Allow me to play devil's advocate here and add another dimension to this conspiracy.
Behold - The future NWO Capital
Now THAT'S some messed up stuff.
