People with power, known to EVERYONE and in the public eye!  Why?  Because they are EASY to blame and you can tell yourself it is all about MONEY and NOT because someone you can't control in bent on destroying you way of life!  When did Bush take office?  7 months prior to 9/11?  If the CIA did plan it...  That stuff would take YEARS.  If anyone KNEW about it, I'd say it was Clinton, not Bush.  He wasn't there long enough to be able to know about a plan.
