"The Latin American drug cartels have stretched their tentacles much deeper into our lives than most people believe. It's possible they are calling the shots at all levels of government." - William Colby, former CIA Director, 1995

WHO MURDERED THE CIA CHIEF?William E. Colby: A Highly Suspicious Death

Still, the fact was that Colby had more enemies than friends. In the period between September 1973 and his dismissal in November 1975 as CIA director, Colby testified before congressional committees 56 times. When Congress asked him a question, he gave a straight answer. The Intel guys hated him for it. They thought it was his duty to lie. So did Gerald Ford and Henry Kissinger who fired him as CIA chief for revealing what were called “the family jewels”—assassination plots and other dirty deeds.
Colby had got rid of a lot of guys in the clandestine service at CIA. I'd talked to ex-CIA officers who hated his guts. Even Lou Conein, one of the best-known CIA operatives in Vietnam, told me he believed Colby had destroyed the agency. And Conein, who knew Colby for many years, liked him. Colby had enemies coming from the Right and the Left.
