The problem is that few recognize the time course of terrorism. There is a long, protracted time period of planning, followed by a short execution phase and short diagnosis phase.

For example, if a nuclear devise were to be detonated, death would arise within seconds. We want to be able to intervene to prevent children and adults from experiencing a terrorist attack, and death.
