How do you decide what to prepare for if you don't know what the threats are and what works to stop them? That info comes from statistics. How do you know what training works, and what tactics work? That information comes from statistics.
I don't know about you but I don't prepare for trouble based on the statistical probability of what might happen to me. I take into account the general categories of bad things that happen (regardless of the "odds" of them actually happening) and try to work with broad spectrum tools and techniques that stand a chance of working under the widest variety of conditions.
I will agree that finding effective countermeasures is enhanced by a study of the statistics regarding success.
