Claudette: I need your support. I’ve got my work cut out for me.
Dutch: You’ll do fine. Whoever sits up there has to have an active mistrust of everyone and everything in this place. I can’t imagine anyone better suited to the job.
Kavanaugh: Vic Mackey kills cops! He, he deals drugs! He beats suspects! You know what he did yesterday? He, he screwed my ex-wife with the sole purpose… of making this investigation seem like a personal vendetta. He may have assassinated a gang leader. And that’s just all in one day. I wonder what he’s gonna do today! I wonder what he’s gonna do tomorrow!
Vic: Let me remind you of a few things you seem to have forgotten. I didn’t kill Terry. You’ve lost your leverage with Lem. And you’re ex-wife’s pussy… tastes like sweet butter.
Kavanaugh: Pretty soon there is gonna be a lonely room filled with empty lockers, huh?
Lemonhead: You and me are the only ones on the way out. I just cut a deal with the D.A.
Kavanaugh: What deal’s that?
Lemonhead: Why don’t you ask the Chief? It’s sitting on his desk waiting for his signature.
Vic: He’ll be out on parole before the blood rushes back to your face.
When Tina hands over "the goods" to the paramedic, you never actually see it. We can't tell if there's something there or if it's just mimed, but whatever it is you can tell it's a fake handoff. Why? No blood on Tina's gloves after she gives it to him.
