This is an important point: corroboration.
CSIS has been collecting a lot of information, as you know, for 30 years. We were even blamed for keeping it too long. They often use corroboration to know whether information is right or wrong. Having information that is not right is a problem in the first place.
You have mechanisms in any organization to make sure that information is correct. Sometimes corroboration, or having many sources regarding the same information, is a good practice, and improving practices would probably help any of those organizations. It exists at CSIS. It exists for us as well, but as was mentioned—
we are not immune
of a mistake. Everybody makes mistakes. It happens from time to time.
