This is dramatic proof of why it is so important to train to stay in the fight until the threat is neutralized. This shooter was mortally wounded yet continued to manipulate his weapon, move to cover, retreat to his vehicle while covering his movement, then drive the vehicle half a mile before succumbing to his wounds. Fortunately the officer recovered from his injuries.
