Homicide: Life on the Street, Season 5

Lewis:
[after beating up Luther] I'm a good cop, Luther. I'm an honest cop. That means I got standards.

Luther Mahoney:
I'm not armed.

Lewis:
Never beat on a man half your size. People won't think it's a fair fight.

Luther Mahoney:
I'm surrendering.

Lewis:
Never put an ass-whooping on a man unless you're damn sure he got it coming to him. I'm going to be beating on you for a little while.

Luther:
You're crazy, Lewis.

Lewis:
I've been a cop for a long time. And drugs out there, we're never gonna win that. There's a hundred open-air drug markets in this city and 50,000 drug fiends out there. And we are taking on human desires with lawyers and jailhouses and lockups and you and I both know human desire is kicking us in the ass. So what I need to know, Luther, is why you couldn't be happy with just the package. If you were just slinging drugs maybe you and I wouldn't be here. But the bodies. What about the bodies? What is up with that?
