[George is confronting PC Carr over his £180 gambling debt with bookmaker Maurie Weitzman whilst clearly maintaining an affluent lifestyle]
PC Tom Carr: I've been a fool, I know. Maybe I like to show off a bit, but I didn't mean any real harm.
PC George Dixon: Well, how much more can you raise?
PC Tom Carr: Ten or twenty quid.
[Carr crosses to his mantelpiece, then starts laughing]
PC Tom Carr: Oh, I get it! You're in with Maurie, are you? He looks after you?
PC George Dixon: [Incredulous] He what?
PC Tom Carr: [Chuckles] You don't want to worry about me, George! I know what it's like, trying to manage on police pay. If Maurie slips you a couple of quid now and then, who's to know?
PC George Dixon: Why you little rat!
[George grabs Carr and throws him onto his bed]
PC Tom Carr: [Protesting] You can't do that!
PC George Dixon: Can't I? I came here with the intention of helping you. You're young and you're a copper, and I don't like to see coppers in trouble. But you're not worth it, I can see that. You cheated Maurie and you'll cheat other people as well; you're nothing but a dirty, cheap little swindler. Now come on, get up off that bed and we'll go down and talk to the Inspector.
PC Tom Carr: [Scrambling to his feet] You can't make me go to the station. I've committed no crime. You're the criminal, busting in here accusing me of being a crook. I could arrest you.
PC George Dixon: Try it.
PC Tom Carr: I wouldn't soil my hands.
[He returns to the mantelpiece]
PC George Dixon: Now, come on son, let's go down and talk to the Inspector. He'll find out sooner or later and then it'll be curtains. This way, well, he - he might give you another chance if you own up.
PC Tom Carr: That bookie don't deserve his money. You can't claim for gambling debts.
PC George Dixon: Now come on.
[Carr pulls away, and stumbles against a table, knocking over a suitcase full of silverware. George inspects an inscribed cup]
PC George Dixon: "Alderman F. Mayhew - from his many friends on the Dock Green Council." The break-ins. You!
PC Tom Carr: Look, Mr Dixon, I can explain that ...
PC George Dixon: You used your uniform - for this!
PC Tom Carr: I had to have money, see? I did it first time just as a lark. Nobody suspected a copper, see.
PC George Dixon: Shut up! You can talk when you get to the station. There's nothing worse than a rotten copper. Nothing! It's the lowest thing that crawls on God's earth. Take off that uniform - take it off!
[Reluctantly Carr begins to unbutton his jacket]
PC George Dixon: And when you've got it off, put on something different. Then I'll arrest you. I'm taking you in, Carr. But not in that tunic.
