U.S. Marshal Samuel Gerard (Tommy Lee Jones) replies - with his own gun pointed at him - that he doesn't care that Dr. Richard Kimble claims he's innocent of killing his wife. A defining scene in a very good movie.
Deputy Marshal Samuel Gerard: Oh. Wow. Gee Whiz. Looky here. You know we're always fascinated when we find leg irons with no legs in them. Who held the keys sir? Old Guard: Me. Deputy Marshal Samuel Gerard: Where those keys at? Old Guard: I don't know. Marshal Poole: Care to revise your statement, sir? Old Guard: What? Deputy Marshal Samuel Gerard: Do you want to change you bullshit story, sir? Old Guard: [pauses] He might have got out.
