Bill Christison, 28-year career CIA man and former sceptic of alternative 9/11 explanations, says the 9/11 attacks were an inside job and the 3 WTC buildings were downed by controlled explosive demolition.
Bill Christison is a former senior official of the CIA, a National Intelligence Officer and the Director of the CIA's Office of Regional and Political Analysis; he retired in 1979 and has written extensively on US foreign policy.
Key quote: "I have since decided that....at least some elements in this US government had contributed in some way or other to causing 9/11 to happen or at least allowing it to happen."
A partial motive advanced by Christison was a cover-up of huge missing funds and criminal complicity in US Intelligence.
