Iron Mike’s Kalashnikov lipped flame as he swept a stream of shells across bike and rider. The gas tank ignited immediately, boosting the immolated cop into a cartwheeling trajectory up and over into the alley. The bike itself did a nosedive. The front wheel bit into the dirt, then the whole machine somersaulted into the fence. Metal screamed and snapped like breaking bones, pushing a whole twelve-meter section of the fencing into a sag outward.
