My observation is that the government tendency to keep secrets apparently does not (or at least in this case did not) extend to keeping the secrets from those who have enough information to detect that there IS a secret. Kodak&#x27;s scientists could tell that nuclear radiation bursts were occurring, and so the US government told them the details of the nuclear testing.<p>This has implications on the kinds of systems that we want to set up to protect against governments keeping secrets that they shouldn&#x27;t. If we make sure that certain groups can tell THAT there are secrets (without knowing what the secrets are) perhaps that provides an effective check on government abuses.
