I dunno, Boston effectively shut down for a few days, estimates are billions in lost economic activity, scores of people with lifelong injuries, four dead. And it cost them a couple of thousand bucks worth of materials and only two young inexperienced men (so far at least).
Frankly, I'm appalled by the bang they got for their buck. We have to do better. The clues were there, the Russians warned us about the older brother. We were asleep.
