From Dirty Harry:

Mayor: "Callaghan, I don't want any more trouble like you had in the Filmore district. Understand? That's my policy."

DH: "Yeah? Well when an adult male chases an adult female with intent to commit rape, I shoot the bastard. That's my policy."

Mayor: "Intent? How did you establish that?"

DH: "When a naked man chases a woman in an alley with a butcher knife, and a hard-on, I take it he's not collecting for the Red Cross."
