* FairForItsDay: Among the recurring characters were a local gay couple, Marty and Darryl. While Marty (introduced first) was portrayed with the usual CampGay stereotypes of the era, when Darryl was later added the Camp was barely present. Barney always treated them with dignity and occasionally made a point of calling Wojo out on his homophobia. Uniformed officer Zatelli wasn't camp at all, and was only revealed to be a closeted homosexual after he'd already been a recurring character for some time; later episodes dealt with his fear of the effect being outed would have on his career, and [[spoiler:his later coming out himself in support of other gays on the force]].
* GeniusBonus: One episode featured a tall, balding curly headed, eccentric man who wore a long striped scarf and claimed to be a time traveller. Typical American viewers would probably not have noticed at the time, but those in the know would have saw a resemblance to the fourth (then current) incarnation of ''Series/DoctorWho''.
* HarsherInHindsight: The second season's opening features a view of the New York skyline with the World Trade Center prominently featured. The first episode of that season is entitled "Doomsday" and centers around a suicide bomber attempting to destroy the 12th Pencinct. Not harsh enough? The aforementioned episode aired on ''September 11'', 1975.
** The second storyline in "[[TheDollEpisode The Doll]]" (1981) concerns an optician who wants to be one of the first [[UsefulNotes/{{NASA}} space shuttle passengers]]. A NASA official tells him that his occupation qualifies him to be considered as a mission specialist. In a buoyant mood, he prepares to leave, only to have Dietrich tell him not to worry about the heat shielding tiles falling off and causing a possible re-entry disaster.
*** The optician's name is Eugene Corbett, a possible ShoutOut to ''Tom Corbett, SpaceCadet.''
* HilariousInHindsight:
** In one episode, a crime victim tells Fish that he looks like Creator/BorisKarloff. ('''Fish''': That's because we're both dead.) In 1986, Creator/AbeVigoda would star in a Broadway production of ''Theatre/ArsenicAndOldLace'' as Jonathan Brewster, a part originally played by Karloff. The line "He said I looked like Boris Karloff" had been kept in TheMovie when Raymond Massey played Jonathan.
** In the second episode, a bomber is on the loose and Barney is looking through records. One suspect is [[Series/TheBigBangTheory Sheldon Hoffsteder]].
* SugarWiki/MomentOfAwesome: When Wentworth saves a union leader from assassination, Scanlon (then a lieutenant at Manhattan South) steals her collar and then files a complaint against her when she protests. Barney is unable to convince him to give her proper credit, but Harris makes Wentworth's actions the focus of his column in his department newsletter... which, as it directly contradicts the official version, would cause quite a few questions downtown. Scanlon is forced to back down after Harris reads it out for the squad and Barney refuses to censor it.
* RetroactiveRecognition:

** Sam Simon also wrote an episode. Simon is best known as co-developer and co-executive producer of ''WesternAnimation/TheSimpsons''.
* TheScrappy: Levitt. Ron Carey was a good comedy actor, but Levitt's sycophantic comments and shamelessly passive-aggressive behavior towards Barney, and acting like ItsAllAboutMe while there was an obvious situation (even crisis) that Barney ''had'' to interrupt him for, made him very grating on some viewers. It made it hard to understand why Barney would bend over backwards dissuading him from a request to transfer rather than instantly accepting it.
* ValuesDissonance:
** [[http://www.hulu.com/watch/9225/barney-miller-rape The rape episode.]] Although the female DA treats the case seriously and laments that there ''will'' be other opportunities to test it in court, it's presented as a comedy storyline and the man is treated not so much as abusive (although he willingly admits that he forced his wife) but as someone who needs to learn how to have a candlelit dinner, and his wife as someone who should probably put out more.
** Additionally, instances of [[DomesticAbuse battered wives]] were PlayedForLaughs in a few episodes.
** The second season episode "Heat Wave" combined the two for extra helpings of dissonance. The A-plot involves Wojo [[DoubleStandardRapeMaleOnMale almost being raped]] while disguised as a woman to catch muggers, and Detective Wentworth being [[ArentYouGoingToRavishMe offended that the would-be rapist didn't pick her]]. The B-plot involves a battered wife with a huge, ghastly bruise over most of her face deciding whether to press charges against her husband. Lots of laughs (from a live audience, not a laugh track) all around, and the applause she got for deciding not to sign the complaint ("He once made love to me in a field of daisies!") was much bigger and more enthusiastic than the applause she got for coming back a couple of minutes later and signing it.
** In "Dog Days", Wojo and Yemana break up a dog-fighting ring and bring in a suspect. Barney gives him a ration for pitting helpless animals against each other, but his treatment of dog-fighting as an ordinary sport and talking as if he were a boxing trainer seems kind of PlayedForLaughs. Or maybe he's just AffablyEvil.
* ValuesResonance: "The Harris Incident." Black detective Harris is shot at by white cops while he's trying to make an arrest. This still happens today, often with tragic results.
* TheWoobie: Levitt can be one. Even if he's sometimes obnoxious, he longs for respect (and a promotion) and is constantly denied it. Also, Wojo, despite his intimidating appearance, has a child-like need for reassurance that turns him into a Woobie quite often.
