Sam Fiaher- Knocking out a Guy who was Already Asleep

  I move into the room and stand behind the man. He’s burly and has a Saddam Hussein-style mustache. I gently put my left hand over his mouth and pinch his nose. The policeman wakes, startled beyond belief. As soon as he leans forward, I grasp him in a “sleeper hold,” which closes off the carotid arteries until he’s unconscious. He falls forward and slides off the chair onto the floor. I figure he’ll be out for about ten minutes if I’m lucky.
