During the night scene in L.A Confidential (1997), Officer Bud White and Dick Stensland are stationed in a car outside a residence, observing as a man inside physically assaults his spouse:
Dick Stensland: You're like Santa Claus with that list, Bud, except everyone on it's been naughty.
Bud White: Guy's been out of Q two weeks.
Dick Stensland: Leave it for later.
What does "Q" mean ?
