But even if the guy will die to steal it that doesn't mean he will live long enough to accomplish anything. And note that he's trying to tote around a gamma source--that's something that can be detected from some distance away. As soon as said terrorist gets it out from behind whatever shields it normally lives behind the alarms start blaring. I remember reading about one, anti-nuke guy kept showing up at meetings at a nuclear facility. Then one day the alarms go off--traced to the old radium-dial watch he was wearing. Rather silenced him.
