The characters of Harris and Carillo had not yet been named when this episode first aired. Kent Staines and Kevin Hare were only credited as "IA Investigator #1" and "IA Investigator #2."
As Frank and Tommy each raise a beer to toast their friend who had just died, they were drinking "Stolman" beer -- a fictitious brand.
The slogan on the doors of the police cruisers read "Excolo Es Optimus" -- Honor is Highest
The license plates on the various vehicles do not indicate which American state or Canadian province the show is based in.
Tommy: On this side here you got the poor, lying and cheating and stealing to pay the rent. And over this little bridge we go, you got the rich, lying and cheating and stealing...
Frank: ...to collect the rent.
Harbin: Hector Arundez was under an IA investigation for taking a payoff.
Frank: Payoff from who?
Harbin: Supposedly, Hector caught some pedophile judge trying to pick up a ten year-old boy in the mall -- gave him money to look the other way.
Frank: Aw, that's total crap! Who initiated the complaint?
Harbin: Rookie riding with him. It was all a box job. Rookie was put up to it by a couple of command officers at headquarters. It wasn't the first time they tried it either.
Frank: Why the hell did they do that?
Harbin: It's personal. Pick a reason.
Frank: So the brass can just initiate an IA investigation just to do that?
Harbin: Oh, man! Where you been?
Frank: Not paying close enough attention, obviously.
(after Frank tried to force the hand of the Deputy Chief Landy)
Tommy: She's pissed.
Frank: So am I.
Frank: Don't run over your rookie.
Hector: Don't give me any ideas.
Hector: How's your dad since the heart attack?
Frank: Heart attack? What heart attack? You know him. He's back on the job in two weeks.
Frank: (indicating to Sgt. Stackley's police cruiser) Check out the licence plate.
(A cardboard sign with "I suck. Call 555-0100" written on it is covering the plate)
Frank: Tryin' to bring a little sunshine into his life. Been on there for two days -- he still hasn't noticed.
Hector: I'm breaking in a rookie. Heard the call...what the hell.
Tommy: Is that him?
Hector: Yeah. He's got a college degree, but a total lack of common sense.
Frank: Well, if there's anybody who can teach him the ways of the police force, it's you, my friend.
Hector: I wouldn't know about that. Just look how you turned out.
Frank: You told me this a thousand times. You call "Tommy's Theory of Irrelativity".
Tommy: I mean, look -- you've got this here: the projects. Addicts; hookers; Tamils; MS-13; Bloods; Cryps; more stuff than we can handle, okay?
Frank: Yeah, but there's a couple nice restaurants just down there.
