A CrimeTimeSoap and DetectiveDrama trope.

A detective (rarely a [[GreatDetective great one]], though), angered by a possible or actual perp being smug, lunges for them and has to be restrained by fellow officers. Not usually part of GoodCopBadCop, more sheer hatred on the part of the detective (often when [[ItsPersonal It's Personal]]). Particularly vulnerable to stuff like IfYouKillHimYouWillBeJustLikeHim when there is actual murderous intent (this is quite rare in police show, though).

* In ''Disney/TheLionKingIISimbasPride'', Timon tells Pumbaa to hold him back, and Pumbaa does so. He then yells "Let me at him, let me at him!" and Pumbaa does so.
--> ''Pumbaa, I think you're missing the basic point here.''
* Gus in ''Disney/{{Cinderella}}'' does this when the stepsisters tear up Cinderella's dress and later when the stepmother locks Cinderella in her room. Jaq has to hold him by his tail both times.
* In ''Disney/LiloAndStitch 2: Stitch Has a Glitch'', Stitch has to hold Lilo back when [[AlphaBitch Myrtle]] taunts her, but when the latter tells her she won't be as good a dancer as her deceased mother, Stitch lets her go and photographs the ensuing smack down.

* The movie ''Film/{{Se7en}}''.
* Parodied in ''Film/TheresSomethingAboutMary''. Ted is suspected of being a twisted SerialKiller by a pair of detectives, but it's in fact a huge mix-up and Ted only ran into the real culprit without even knowing. This starts a MistakenConfession where Ted casually admits his habit of "picking up hitchhikers". When he says that he might have had up to fifty hitchhikers in his life and makes light of this fact, the more unnerved of the two cops bashes Ted's head into the table in rage.
* Played straight in ''Film/MadMax'' when one of the bikers is let go on a "No Contest" plea.
* ''Film/LethalWeapon'', where they let Riggs fight with Mr. Joshua at the end.
* ''Film/DirtyHarry'', although it is more of a statement than done in anger.
* Sgt. Kelloway from the movie version of ''Film/TheMask''. Granted, it had definitely become personal at that point, what with them finding a picture of Kelloway's wife in Stanley's pants.
* In ''Film/LAConfidential'', Bud White's BerserkButton is triggered as he listens to a black suspect confessing to the incidental crime of kidnapping and raping a Mexican woman. He shatters the back of the chair he is leaning on, storms into the interrogation room, violently pushes the suspect against the wall, and places the barrel of his gun into his mouth. Go 50's!
* One of the methods of dealing with bullies that ''Film/DrillbitTaylor'' teaches the boys is the Holdback Technique, which is faking this trope to make the other party think you want to fight, ideally making them back off. When the boys try it at school, the one being held back is punched. Drillbit is surprised they actually tried it.

* When Literature/HonorHarrington learns, in ''The Honor of the Queen'', that a P.O.W. prison guard has been [[MoralEventHorizon ordering prisoners raped and beaten]], she goes after him with murderous intent. Only the intervention of one of her subordinates, who shoves her arm aside as she's pulling the trigger, keeps her from killing him. Rather than an IfYouKillHimYouWillBeJustLikeHim speech, though, she's told that there's no need to commit career suicide by killing him without a trial, when there's plenty of evidence to convict him and hang him after a full court-martial.
* Inverted, subverted, and played straight to different degrees in J.D. Robb's ''Literature/InDeath'' series. Most of the time Eve, the [[GoodCopBadCop Bad Cop]] in almost every interview, intentionally provokes this reaction, sometimes even letting them land a blow to justify EpicBattleBoredom. At the same time, some of the series' villains and their {{Sympathetic Murderer}}s will elicit this reaction from HotBlooded cops if [[ItsPersonal it's personal.]] Sometimes it looks like one party or the other will snap and lunge... only to [[GenreSavvy cool down and call a lawyer]] or [[INeverSaidItWasPoison point out a flaw in the suspect's story.]]
* In ''Homicide: A Year On The Killing Streets'', one of the detectives, having brought in a suspect who raped and beat to death his toddler stepson, contemplates giving him a serious station-house beating with the knowledge that no one in the building would blame or implicate him in any way. He doesn't do it, but not out of compassion: he realizes that, tomorrow, somebody just as bad or worse will be in the same interview room and in the end it doesn't accomplish anything. He convinces another detective to conduct the interview instead while he regains his composure.
* An Exbrayat story has this: the inspector in in the interrogation room with the smug little drug dealer, along with a [[TheBigGuy huge]], [[CoolOldGuy middle-aged cop]] whose only daughter died of an overdose. When the dealer starts taunting the inspector, he starts to look as though he's going to punch the smartass... only to turn around and deck the other cop in the face. As both stare dumbfounded, he delivers this awesome line: "You disappoint me, Gunther. A two-bit drug dealer lays a hand on you and you just sit there?" [[NoHoldsBarredBeatdown Understanding dawns in the cop's face eyes just before fear does in the dealer's.]] Later we're told that the official version was that the cop saved the inspector from a violent criminal.

[[folder: Live Action TV ]]

* In the pilot episode of ''Series/{{Kojak}}'', "The Marcus-Nelson Murders", Kojak has to be restrained from clobbering the killer, Teddy Hopper, a man who he had been mentoring and defending, convinced of his innocence.
* Elliot Stabler of ''Series/LawAndOrderSpecialVictimsUnit'' has had trouble controlling himself before.
* Averted in ''Series/LawAndOrderCriminalIntent'': in Season 6, Det. Goren is interviewing convicted serial killer Mark Ford Brady in an effort to find more of his victims before he is executed, and when it becomes clear that Brady [[spoiler: raped Goren's mother and may well be his own father]], Goren snaps and goes for his throat. There's a prison guard right there in the room, but he doesn't interfere in any way; Goren just gets control of himself.
* ''Series/CriminalMinds'':
** Happened in an episode, but it was not one of the team who went across the table at the unsub; it was in fact the priest of the local church, who had helped organize a search for a missing woman in the community, and had been asked to talk to the suspect after they captured him as he was a parishioner and might talk to the priest. The priest -- who has remained calm and composed the entire episode -- finally loses it when the suspect reveals he [[spoiler: chopped up the woman and made her into a stew that he then fed to the search parties.]]
** Subverted by the episode "Masterpiece", where it's after Rossi's CrowningMomentOfAwesome that Jason Alexander's [=UnSub=] lunges across the table at Rossi - who promptly gains the upper hand, slams his head against a plate-glass window a couple times, and then calmly lets him go.
* Deconstructed in an episode of ''Series/{{CSI}}'' where the murderer was [[RabidCop a cop]] who ended up accidentally [[PoliceBrutality killing an innocent eighteen year old teenage suspect in interrogation who wouldn't confess]] by not so accidentally knocking him over onto the concrete floor and let him die of head trauma.
* In ''Series/TheXFiles'', Mulder faces a serial child murderer who claims Mulder's sister as a victim. Driven over the edge, Mulder smacks him out of the seat. When the perp yells, "He hit me!" the guard shrugs and says, [[BlatantLies "I didn't see it."]]
* Parodied in an episode of ''Series/TheLastDetective'', where the protagonist, who is as far from being a RabidCop as is possible does this against a criminal who beat up his best friend. It's a rather ineffectual lunge and Dangerous' boss, an OldFashionedCopper, finds it amusing.
* ''Series/ThePhilSilversShow'': A variation of this trope, where Bilko ordered his men to hold him back in a serious and threatening tone, then proceeded to struggle against them trying to get at the guy who pissed him off. As he starts to break free, he urges them with greater and greater urgency to hold him back better (so he doesn't have to actually fight).
* ''Series/{{CSI NY}}'':
** Danny after Aiden's death. He's wanting very badly to rough up the guy he thinks did it, but Mac is admant he can't because it has to go by the book. It was someone else who killed her anyway in the end.
** There was one that initially appeared similar to the CSI example above, but it turned into a subversion. Flack has the misfortune for a kid to die in custody, during interrogation. It appears he might have gotten overzealous with the kid, but it later turns out the death was drug induced.
* Often happens with Bill Oddie in ''Series/TheGoodies'', though there it's played for comic effect.

* Almost every time Spinelli tries starting a fight in ''WesternAnimation/{{Recess}}''
* A pretty weird one happens in ''WesternAnimation/ThePowerpuffGirls'' episode "Los Dos Mojos". When a knock on the head makes Bubbles think she's Mojo, Blossom is about to fight her, but Buttercup holds her back, reminding her that it's Bubbles. Then Bubbles insults Buttercup... And then ''Blossom'' has to hold ''Buttercup'' back.
* ''WesternAnimation/EdEddNEddy'':
** "Is There An Ed In The House" has Edd wanting to get at Sarah for giving him a cold. Ed has to hold him back.
** In "Cool Hand Ed", the Eds are trying to escape school and Jonny and Plank want to join them. When Eddy refuses, Plank threatens to snitch on them for revenge. Then Eddy tries to attack him but Ed holds him back. Eddy even yells "Let me at him!! I'llI'll"
** In the movie, Lee does this when [[spoiler:Eddy's Brother beats up her "boyfriend" Eddy in front of everyone]]. Her sisters have to hold her back.
