Well it is simple, if there were real facts and true evidence in those conspiracy theories then there would be people arrested and prosecuted for the murder of those thousands of people in the towers. Politics is one thing but if politicians intentionally murdered 3 thousand of our own people they would never get away with it and would be prosecuted for it. A crime of that magnitude could not be covered up because too many people would know about it and they would have clear evidence of the act. There is no clear evidence of any crime on the administration's part so there is no trial and never will be becasue it just did not happen. That is how conspiracy theories work. All they need is inuendo and unsubstantiated statements. I used to beleive the conspiracy theories back in the day when it was believed that the government was watching us in our living rooms though the TV and tapping every phone. "Big brother" is not after you and really couldn't care less about you and your mundane lives.
