Law & Order: Special Victims Unit, Season 3

[Hawk has chased the killer to the roof of a building; when Stabler catches up, the suspect is clinging to the ledge as Hawk watches, ready to let him fall]

Stabler:
Hawk? Hawk, don't do this.

Hawk:
Don't do what, partner?.

Stabler:
We both know this isn't right.

Hawk:
We both know the system sucks. This way it's just natural selection. [steps on the suspect's hand]

Stabler:
Hawk, you do this, you're no better than he is.

Hawk:
He sure as hell won't kill anybody else.

Stabler:
This is no way to end it. Come on.

Hawk:
He's an evil man, Elliot.

Stabler:
And all it takes for evil to triumph is for good men to do nothing.

Hawk:
You gonna let an old drunk do all the work? Gimme a hand.

[Stabler walks up to him, and the two help the suspect onto the roof and cuff him]
