Plausible deniability is the process by which a country, agency, or individual maintains the ability to deny involvement in an operation. For instance, if there is no record that you received a memo, you could read the memo but still profess ignorance. Compartmentalization of our government agencies allows secret project groups to set up exclusive lines of communication. In this way the most powerful people are able to coordinate the actions of many who have no knowledge of their role in a covert plan.
Former CIA officer, Tom Donohue, said the CIA doesn’t do anything unless it meets two criteria. The first criterion is “intelligence potential.” The program must benefit the CIA; maybe it tells them how to overthrow a government, or how to blackmail an official, or where a report is hidden, or how to get an agent across a border. The term “intelligence potential” means it has some use for the CIA. The second criterion is that it can be denied. If they can’t find a way to structure the program or operation so they can deny it, they won’t do it. Plausible denial can be as simple as providing an officer or asset with military cover. Then the CIA can say, “The army did it.”
Plausible denial is all about language. During Senate hearings into CIA assassination plots against Fidel Castro and other foreign leaders, the CIA’s erstwhile deputy director of operations Richard Bissell defined ‘plausible denial’ as “the use of circumlocution and euphemism in discussions where precise definitions would expose covert actions and bring them to an end.”
Everything the CIA does is deniable. It’s part of its Congressional mandate. Congress doesn’t want to be held accountable for the criminal things the CIA does. The only time something the CIA does become public knowledge – other than the rare accident or whistleblower – is when Congress or the President think it’s helpful for psychological warfare reasons to let the American people know the CIA is doing it. Torture is a good example. After 9/11, and up until and through the invasion of Iraq, the American people wanted revenge. They wanted to see Muslim blood flowing, so the Bush administration let it leak that they were torturing evil doers. They played it cute and called it “enhanced interrogation,” but everyone understood symbolically. Circumlocution and euphemism. Plausible denial.
