CONTROLLING SCIENTIFIC INFORMATION: This guy isn't happy about it. I tend to agree. I don't mind classifying particular bits of information (e.g., "This cable is crucial, and if you cut it the whole grid goes down.") but classifying science seems more dangerous than me. We're so much stronger than our enemies because of open scientific research; closing things down beyond the level of very specific threats is dangerous.
UPDATE: Justin Katz weighs in. I think there's a certain amount of talking past each other on this subject, though. Hmm. Maybe I should make this a column . . . .
