Law & Order, Season 18

[Lupo is unhappy with Cutter for browbeating a young witness into testifying against her mother.]

Lupo:
You learn that in law school?

Cutter:
Right out of law school. Nothing but drug cases for five years. Would you feel better if I offered her a lollipop?

Lupo:
I'd feel better if you hadn't roughed her up.

Cutter:
How do you think her mother got her to lie? I'm playing to win, detective, and winning means Katherine Waxman in jail.

Lupo:
Is this some kind of sport to you?

Cutter:
[pause] Stick with your law books, detective. On the page, the law is a much purer thing.
