I've always issued the challenge to anti-nook kooks and others here on FR and elsewhere who say how vulnerable nuclear plants are to armed attacks and how supposedly weak their security forces are to do the following: try a raid yourself if its so easy. If these places are so poorly protected, surely smart and resourceful (to hear them tell it) anti-nuclear kooks can pull it off. Go ahead and try to break into the vital areas of one of these facilities. See how long they live.
You'll be shocked and chagrined, I'm sure, to hear that there have been no takers.
