The Mayor: Callahan...I don't want any more trouble like you had last year in the Fillmore District. You understand? That's my policy.
Harry Callahan: Yeah, well, when an adult male is chasing a female with the intent to commit rape, I shoot the bastard...that's my policy.
The Mayor: Intent? How'd you establish that?
Harry Callahan: When a naked man is chasing a woman through a dark alley with a butcher knife and a hard on, I figure he isn't out collecting for the Red Cross. [leaves]
The Mayor: I think he has a point.
