I have to agree. That's the way to handle it!
Terrorists aren't used to it being dealt back the way it came. Disappearing into the bowels of Quantico never to be seen again just isn't much of a deterrant apparently. Executing them like dogs in public should be more of one.
Bravo! We've been needing a Dirty Harry kind of attitude for a while now. Thought that would happen in the US first. A bit surprised but delighted it's happened in England first.
