This partially unscripted comedy brings viewers into the squad car as incompetent officers swing into action, answering 911 calls about everything from speeding violations and prostitution to staking out a drug den. Within each episode, viewers catch a "fly on the wall" glimpse of the cops' often politically incorrect opinions, ranging from their personal feelings to professional critiques of their colleagues.
