CIA museum: Inside the world’s most top secret museum

“This museum is not just a Museum for history’s sake. This is an operational museum. We are taking CIA officers [through it], exploring our history, both good and bad,” says Mr Byer. “We make sure that our officers understand their history, so that they can do a better job in the future. We have to learn from our successes, and our failures in order to be better in the future.”
