In Cold Blood (1967)

Dick: I don't know gold dust from diarrhea.

Reporter: I see, the hangman's ready. What's his name?
Alvin Dewey: We the People.

Alvin Dewey: Someday, somebody will explain to me the motive of a newspaper. First, you scream, "Find the bastards." Till we find them, you want to get us fired. When we find them, you accuse us of brutality. Before we go into court, you give them a trial by newspaper. When we finally get a conviction, you want to save them by proving they were crazy in the first place.

Perry: I despise people who can't control themselves.

Dick: There's two kinds of laws, honey. One for the rich and one for the poor.

Perry: That was stupid - stealin' a lousy pack of razor blades! To prove what?
Dick: It's the national pastime, baby, stealin' and cheatin'. If they ever count every cheatin' wife and tax chiseler, the whole country would be behind prison walls.

Dick: Did you see those guys? They coulda robbed us.
Perry: What of?

Perry: It's true! Really true! We're on our way and never coming back. Never! And no regrets.
Dick: For you. You're leaving nothing. What about my old man... and my mother? They'll still be there when my checks start bouncing.
Perry: It's nice the way you think about your folks.
Dick: Yeah! I'm a real thoughtful bastard.
