Summary A routine stop for a broken taillight escalates into a frantic car chase and deadly shootout in Sioux City, Iowa. A call to a domestic dispute on a Sunday morning in a quiet Deltona, Florida suburb is usually just a marital disagreement settled with a few calming words. This time it spirals out of control as a shooter holds his family hostage and pins the officers down with heavy gauge gunfire. The pressure is on to save his wife and children and apprehend the suspect without triggering a tragic end. A rookie officer stops to check out a man walking along a busy highway in Ohio. The pedestrian has a dark secret, and suddenly lunges at the officer with a hunting knife, forcing him to back into the speeding traffic. The tense stand-off presents a severe dilemma to the officer - which will call for lethal measures if back-up doesn't arrive. In Body Cam: Behind the Badge former FBI Tactical Instructor, Greg Shaffer, unpacks how officers' training prepares them to assess and contain the deadliest threats.
