The only problem with that is, the general public will eventually get tired of it and begin to fight back. This is why we have not been attacked here since 9/11.
Up to now, the terrorists are targeting innocent vulnerable people who they know, won't fight back or who may litteraly hunt them down like dogs.
The Terrorists really do not have any solid plan that will be able to penetrate our security. They are still too primitive and they stand out like a sore thumb
