From the fourth season premier "Cure" as the assistant chief confronts a rookie cop over him shooting a dog (obviously in itself not funny, but the aftermath).
Assistant Chief: Where's the triggerman? Vic: The kid's just a rookie, sir. Assistant Chief: Too young to read mandates from the Chief's office? Vic: There's nothing else he could have done. Assistant Chief: Is he the shooter? Vic: Sir, I'm telling you, the kid had no choice, the dog was reaching. [cut to the dog with a pistol between its paws] Vic: It was kill or be killed.
