Counterterrorism is most effective when it doesn't make arbitrary assumptions about the terrorists' plans.

Countermeasures that defend against particular targets, or assume particular tactics, or cause the terrorists to make insignificant modifications in their plans, or that surveil the entire population looking for the few terrorists, are largely not worth it.
