The CIA's influence is such that it can successfully forbid other agencies of government to conceal its crimes if they find out about them. Example: “The Drug Enforcement Administration(DEA) knew about and helped cover up the CIA's involvement in Guatemala's drug war murders, a former DEA agent said,” the AP reported on July 23, 1996. Although the DEA denied the allegations, Celerino Castillo, who was a special DEA agent assigned to Guatemala, said he and other DEA agents there “were aware of specific murders committed by the Guatemala military with CIA involvement and were ordered to lie to keep the crimes secret.” AP said the Intelligence Oversight Board issued a report stating CIA agents in Guatemala “were credibly alleged” to have ordered, planned or participated in human rights violations such as murder, torture and kidnapping.” (I.e., Castillo's charges were true.) So it has long since gotten to the point that officials of other U.S. agents cannot report the CIA's crimes either, as if they were under a Mafia oath of secrecy.
CIA employees themselves are forbidden by secrecy agreements (under the Intelligence Identities Protection Act passed under President Ronald Reagan) to write anything about the Agency without first clearing it with a CIA publications review board. Accordingly, the CIA recently cracked down on a former officer who wrote under the pseudonym “Ishmael Jones.” His “crime” was to publish two years ago “The Human Factor: Inside the CIA's Dysfunctional Intelligence Culture.” The Associated Press quotes Jones as saying, “CIA censors attack this book because it exposes the CIA as a place to get rich, with billions of taxpayer dollars wasted or stolen in espionage programs that produce nothing.” Denying the truth, however, is a long established CIA practice. John Stockwell, for 13 years a CIA station chief in Angola or a top man in Viet Nam, said in a lecture, “What I ran into...was a corruption in the CIA and the intelligence business...what I found was that the CIA, us, the case officers, were not permitted to report about the corruption in the South Vietnamese army.”
