This all can’t be happening; it really can’t.  So what’s the harm of knocking over one imaginary cop?  Nothing, right?  You barrel into the cop with your head down, catching him in the cup with your face.  He falls over backward with you on top of him, and he promptly starts beating your face with his nightstick.  After the first blow you cover your face with your hands; the second slams your right hand’s fingers flat and you roll off and bang your back on the concrete.  Two more cops come, one helps the fallen, sweaty guy up and the other kicks you in the ribs for good measure.  Your hands are tightly chained to your waist and they consider leg irons, but then just cart you into the station on a hand truck.
