[Harry Callahan has to explain why he shot a man] 
Harry Callahan: Well, when an adult male is chasing a female with intent to
commit rape, I shoot the bastard. That's my policy. 
The Mayor: Intent? How did you establish that? 
Harry Callahan: When a man is chasing a woman through an alley with a
butcher's knife and a hard-on, I figure he isn't out collecting for the Red
Cross!
