After Davis tells Karen it was him who fired his gun on a farm, after she told about a report of gunfire:
Karen: I know you're my senior officer, so I say this with all due respect: How stupid are you? You can't just fire your gun off willy-nilly!
Davis: It wasn't willy-nilly. It was at crows.
Davis: It wasn't willy-nilly. It was at crows.
