• Detective’s burnout: Jack Taylor eventually leaves the force, haunted by the case's lack of closure:

  "I quit and I went on. I was young. I was inexperienced. I was ashamed of. Actually, I felt like I was running. It was my first homicide and I didn't solve it. That's not right. And that's what's haunted me." – Jack Taylor, [22:53]

  "Police officer killing another police officer. I mean that just hard to fathom." – Bruce Schock, [30:47]

  "Ruble had backed him up against the wall and had a hunting knife that he held to the ribs of Smith and advised Smith that, you know, if he ever said anything, that he knew how to kill a person by sticking this knife in between the ribs and twisting so that they wouldn't even make a sound." – Bruce Schock, [40:42]
