Are you aware of the chemical complexity of the so-called "peroxide bomb"? The (very precise!) solution would have needed to be mixed continuously for at least three hours at or below freezing, then allowed to warm up to room temperature, then filtered and washed in an alcohol bath, etc... The point is that while I have no doubt of those dudes' bad intentions, it's highly unlikely anybody could have pulled that off, much less by using juice boxes to smuggle the ingredients on board. Banning juice boxes is what the rest of us call "grasping at straws"... which is what most of the Fed's antiterrorism tactics have been. I think America is (very slowly) starting to realize that in this arena, the cure might be worse than the disease.
