Chris Wallace is making the common mistake...profiling the objects and worrying about THEM rather than profiling people. Wallace also makes the mistake of thinking that throwing money at a problem is the answer. I hope listeners understand Chertoff's very good answer which focuses on the real problem, which is human ingenuity. If they want to kill you, and they are willing to die to do it, they are very hard to stop.
To me it is so fundamentally simple but so many people do not grasp it or want to grasp it. For to grasp it means you have to deal with it and many people IMHO are burying their heads in the sand hoping it goes away. It will not!!!
I'll second your thought...just a few posts downstream from your original.
This is why MAD will never work with these fascists, and God help us when they have NUKES!
