[UPDATED] Either terrorists are dumb, or they aren't very committed to their causes.

I've been saying this, somewhat jokingly, for years.

But apparently the TSA actually thinks it's the former. Or, at least, they've set up security procedures on the assumption of terrorists' inferior intellects.

Not entirely certain that's the right tack, guys.

UPDATE: By the way, Jeffrey Goldberg's Atlantic article about TSA "security theater" is hilarious and-- I almost wrote "frightening," but actually it's really not. And that's sorta the point.
