"This shows the heart of defensive tactics – not wrist locks and pig piles, but control. Control; first and foremost, of yourself, no matter how you feel about it – control of your slamming heartbeat, dry mouth, deadened ears, trembling hands that cause the front sight of your gun to disappear and the face of the man who may be about to die become huge, distorted into gargoyle-like ugliness. Control of your tactics, your partners, the perp, the environment; control of the outcome. This is very unlike, and infinately harder than the simplicity and single focus of combat (kill) and self-defense (escape). In defensive tactics, you have to exist outside yourself, be a witness to the action, in order to stay objective. You have to control your mind, body and spirit as if all three were tools, and still remain focused, and committed to, the mission, the outcome. Can this kind of objectivity be trained, be learned?"
