But it's not just the lives of the innocent they must protect - they must also save the lives of the perpetrators they're confronting. One of the most difficult problems is avoiding lethal confrontations in "the kill zone" - those moments of truth when it's kill-or-be-killed. Fight Science will use a team of top physiologists, engineers, and weapons experts to reveal how Law Enforcement personnel utilize cutting-edge technology and weapons, as well as their knowledge of human physiology, to save lives.
