in general he was not a big fan of dramatic arrests , but he knew from long experience what worked and what did n't with shocked and unpredictable subjects , so he screamed get out of the car get out of the car get out of the car as loud as he could , which was plenty loud , and the guy behind the wheel more or less tumbled out , and then reacher was on him , forcing him down , flipping him , jamming him face down into the blacktop , his knee in the small of the guy 's back , the glock 's muzzle hard in the back of the guy 's neck , all the time screaming stay down stay down stay down , all the while watching the sky over his shoulder for more lights .
