Officer John Cooper is a seasoned patrol cop who most recently served as a training officer for Officer Ben Sherman. Suffering severe back pain from various work-related injuries, John became increasingly dependent on painkillers, making it almost impossible for him to function in his job. Recent surgery on his back should put him on the road to recovery, but the emotional wounds caused by his drug addiction may take longer to heal. Now that Ben has passed his training period, John is partnered with Jessica Tang (special guest star Lucy Liu), who brings her own set of emotional baggage to their patrol car. John is very guarded about his private life, but that may change when he uses his own experiences to help a suicidal teen.
