As for the CIA and the Delta Force, don't doubt anything as it was the CIA involved in the Mena Connection cocaine operation gone sour and two young teenage boys death which will remain a mystery during Clinton's time as Governor of Arkansas. The CIA is capable of anything. George Bush Sr., knows this very well as he was head of the CIA. (Not knocking him either).
As for the CIA knowing anything about the recent attack on the WTC, well I think this goes beyond the CIA! This was definitely planned by those of the blue blood types who want to further their agenda to bring chaos to establish their twisted New World Order. The CIA is just another paramilitary operation working in cohorts with FEMA.
I, for one, have never argued otherwise...MUD
