Your argument is that unless we check everything, we shouldn't check anything? Interesting thinking.
That is not my argument. My argument is that it doesn't make sense to strip search some grandmother from Iowa when she wants to fly to her granddaughters wedding when there are far more ways for evil to be done.
You know damn well what my argument is.
So does it mean that we're all supposed to wait until a rail car entering San Diego or Galveston has a nuke on board before we complain that the government didn't check them?
