Fullmetal Alchemist: At the very start of the series, when Edward and Alphonse are battling the fake priest Cornello, Edward is trapped but has a huge microphone hidden as Cornello explains how he is manipulating the populace and so on.
Cornello: I was once even the CEO of Fox Entertainment, and it was I who canceled such great shows as Arrested Development and Futurama! * evil laugh* Ah ha... I'm evil...
Patlabor: One of the people behind the terrorist attacks, Shigeki Arakawa, refuses to confess anything. Shigeki Arakawa is also Affably Evil. He went to Kiichi Goto when Yukihito Tsuge decided to alter the plan and start a limited war that would topple the Japanese government. Shigeki Arakawa’s original plan was a harsh political protest that used limited and controlled violence. Goto also agrees with Arakawa’s observations on the reality of peace, war, and political leaders exploit chaos instead of using a measured response.
Done in the last episode of Gunsmith Cats when Haints finds Radinov in his office and launches into a rant about her failures, only to discover that she's really Kate with a wig and a microphone.
This happens twice in Martian Successor Nadesico, transmitting some things Nergal would rather have remained hidden to the entire ship. The second time, in fact, Mr. Prospector seems to have some sort of "reveal bad guys' secret" button (designed to look like Ruri's face for some reason) on his shirt that he casually brushes as their captor gets rolling.
Infinite Ryvius: Captain Airs Blue at one point considers betraying and abandoning the crew of the Ryvius, unaware that a treacherous subordinate has turned on the ship's intercom. Needless to say, he isn't Captain for much longer.
A non-villainous (sorta-kinda) happened in Get Backers.Makubex finally explains that stealing the implosion lens wasn't just a plot to ransom the gods of Mugenjou and return things to how they before Ginji left; it was all prophesied in the Archive, and he was just doing his best to play his part and see if he could find a way to break the gods' control. He even revealed that his public persona as the "demon king" was largely a product of his virtual reality systems. Ren runs in after he finishes talking, reveals that she used his computer to broadcast it all over Lower Town, and that they're all waiting outside, cheering wildly and yelling things like "Long live Makubex!"
One Piece had one during the Enies Lobby arc where Spandam, after accidentally activating the Buster Call, is gloating to Nico Robin about his future plans and how all the Marines under him are sheep. The kicker to this is that HE was the one who left the radio on for all to hear. Then he weakly tries to cover it up by trying to imitate Luffy when he finally notices this. No one is fooled, of course.
Sket Dance plays this completely straight when a teacher caught framing a pupil for his own misdeeds confesses all with the immortal lines: 'No matter what you say, nobody will believe you!' Unfortunately for him, he was being broadcast over the school intercom system at that very moment, and the Sket-dan had fiddled with their classroom's speaker so that he wouldn't notice it.
In Yu-Gi-Oh! 5Ds, during his fight with Yusei, Divine reveals that he was the one who murdered Misty's brother (Misty was under the impression that Aki had, and had become a Dark Signer to seek revenge - acquiring the use of Jibakushin (Earthbound God/Immortal) Ccarayhua).He discovers too late that Yusei's Duel Disk had a microphone in it, which he had activated beforehand, and becomes Ccarayhua's dinner. Though it certainly doesn't help that when Misty angrily speaks to him a few moments after Yusei reveals his trick, he responds withEvil Gloating.
Peach Girl evil mastermind Sae is tricked by Kairi into expounding on her patented Wounded Gazelle Gambit routine, and how she has repeatedly made Momo look like a monster before the class. Unknown to her Touji is right around the corner, and hearing her bragging finally wakes him up, and he in turn makes damn sure the class knows who and what Sae really is. The worst part was, they kind of already did, but admitted falling for an act they themselves had been victimized by before—and sadly, would again before all was done.
In Ouran High School Host Club, the school's newspaper editor tries to engineer the downfall of the Host Club, only to have his plans thwarted by a recording machine disguised as a first aid kit which Kyouya placed into the newspaper room.
20th Century Boys: An incredible inversion. For the entire series, Friend's Villain with Good Publicity status was his greatest advantage over the heroes. And just before the endgame, he throws it away willingly, casually telling the entire world the atrocities he's done on live television. At that point, he's so crazy and his plan so close to fruition that it doesn't really matter anymore.
Largely how Near manages to expose Light as Kira in Death Note, sans the tech equipment but Light's god complex ego is more then enough.
In an episode of Busou Renkin, homunculi were attacking the protagonists' high school, and the main heroes were fighting them off. One student was a collaborator with the villains, and so used the intercom to convince the other students that the heroes were also enemies so they would attack them. The hero's friends call-out the student over the intercom and get him to reveal his treachery.
Pokémon: Zoroark: Master of Illusions has Grings Kodai's plan curving for a meteoric downward spiral after Zorua nicked his forearm. This had the side effect of breaking his illusion canceller, but he was too absorbed in both his own ego - as he gloats to Ash about his Dark Secret - and Zoroark's illusion to tell the difference as he drew power from a fake Time Ripple projected a few feet closer to Kodai than the real one, allowing Ash's friends to record his gloating on video. Then time rewinds in front of him, revealing the truth; he loses full functionality for his device shortly thereafter frying Zoroark, who fries it back, and stumbles into another illusion, whereupon he falls unconscious after falling off a podium in the Boccer arena, believing the railing for his "airship" was a few feet further ahead. This trope kicks in the next morning, where he wakes up to hear aforementioned gloating broadcast to everyone in Crown City via his own TV network. That roar from Zoroark? A rough translation is "enjoy your ride on the Party Van, asshole!"
In Tiger & Bunny, Agnes and her crew combine this with Hoist by His Own Petard when they expose Maverick by broadcasting his monologue live on Hero TV, a program of his own media company which he was using up to that point to further his schemes.
One memorable episode of Detective Conan had Conan cornering the killer-of-the-week in a parking lot and spouting off the details of the crime. The killer is at first taken aback at being found out, but calmly confesses to the murder when he realizes the police would never believe anything a little kid like Conan says. Conan admits this to be true — which is why he taped the whole conversation.
The girls are singing for an animal preservation charity. After the rival boy band's leader sets them up by way of a fur coat, the girls pretend to be groupie journalists to get the guys back. They do, of course, and the boy band is thrown out and the Cats welcomed back with open arms.
Valerie, where she pretends to be helping a con man so she can get him to tell her about the scam and what suckers people are — she is wearing a wire and broadcasting this to the entire school.
The post-Zero Hour incarnation of the Legion of Super-Heroes spent an entire arc building up to one of these, complete with the Legion's leader becoming Not Himself to ingratiate himself to the target, several Legionnaires faking their deaths, and one of the presumed-dead Legionnaires then impersonating a third party to take credit for the villain's schemes in order to prompt the Just Between You and Me moment, which was of course broadcast on live TV - all without cluing the reader in until The Reveal.
For a while Lex Luthor was President of the US (really!), and genuinely tried to protect the country (and Earth) from several of the cataclysms that occurred during his term. Then his hatred of Superman got the better of him and he tried, through a heavily convoluted and highly illegal scheme, to frame Superman for attempting to destroy the Earth by drawing an asteroid to Earth. It almost worked, until he ranted to Superman that he truly thought he was guilty, repeatedly admitting to playing the public like a flute and that he intended to teleport off planet (using Illegal Alien Technology from Darkseid) before the asteroid hit, leaving everyone else to die. Luckily, he didn't know Batman was taping the whole thing (in addition to, as Bruce Wayne, buying up all his assets so that he couldn't start over, or at least for a while).
Lex may be completely crazy, but he's not completely wrong The asteroid IS headed for Earth because of Superman; it contains his cousin, Supergirl. Supergirl's escape ship was following Superman's journey, but unfortunately came with a giant chunk of the planet Krypton attached. Luthor's crime here wasn't framing Superman, but leading a manhunt for the hero instead of simply asking for his help in destroying it.
Lex gets this a lot. In an Elseworld story, he gives the villain speech in front of Supergirl while Batgirl was broadcasting it live on network TV, destroying his reputation.
The first arc of Scott McCloud's Zot! ends with the titular hero interrupting the Evil Chancellor as he gives a live planet-wide broadcast about how their world's Holy War against Earth is going. The villain makes sure to turn off all the cameras before admitting to Zot that, yes, he killed the king, the queen, and his rivals, and engineered the war as a way of consolidating power—but then Zot reveals the tiny robot that's been following him around, which has video cameras for eyes and a built-in broadcast antenna. Guess what the robot's been doing?
Spider Jerusalem uses this against the President in Transmetropolitan. He purposely gets seen using a real gun (something that's out of character for him) earlier in the day, so that the increasingly unstable President will make very sure he's not armed, instead of making a cursory check guns and then checking for bugs.
Subverted in Y: The Last Man, when ex-cop turned brothel owner You confronts Epiphany, a Canadian pop star who's using her influence among teenage Japanese girls to recreate the Yakuza, and broadcasts her comment ("Those retarded Japanese fangirls worship me like a god!") to the guards outside. When informed of this Epiphany simply retorts: "Oh please! Those groupies already know I couldn't give two shits about them!"
In the Donald Duck comic "Outlanders" Donald, Scrooge, Huey-Dewey-Louie are teleported to a steampunk world, where Beagle Boys got the Money Bin, and sent alternate Scrooge to work in coal mine. He then takes his revenge by tricking them to confess how they did it, which was in fact broadcasted on a giant sheet.
The 'Crazy Eights' storyline in the Marvel Comics "Wonder Man" book. Eight newly superpowered friends of Wonder Man manage to record L.A's top security firm as really being a bunch of murderous thugs for hire. A violent chase ensues all over town, ending with a Hail Mary pass to a reporter acquaintance. Ironically, the reporter's view of costumed people tussling with the security firm just increases her curiosity to view the tape.
Raana Tey from Knights of the Old Republic falls victim to this when she gloats about the murder she participated in and framed the protagonist for in front of the sister of one her victims (who Raana had been manipulating). It doesn't end well for her. Subverted in that Zayne didn't really plan it to happen.
Used in an issue of Doctor Strange, with Clea activating the crystal that Umar the Unrelenting used to make announcements to the public. It might have gone better if Umar hadn't drained the barrier that prevented the Mindless Ones from rampaging across the Dark Dimension; part of her power was drawn from popular support.
Action Comics #556: Vandal Savage, then an immigrant from Earth-2, decided that being a Villain with Good Publicity wasn't enough, and began videotaping all his meetings with Superman as part of his plan to make Supes a Hero with Bad Publicity. Superman secretly places a transmitter on Savage's recording device which then feeds to local TV station WGBS, then goads the villain into revealing his plan and sneering at the "sheep" of Metropolis. Superman consulted Batman beforehand to make sure the plan was viable.
In the last issue of Six Gun Gorilla, Blue manages to trick one of the people involved in a plot to prolong the civil war in the Blister so Bluetech can make a fortune broadcasting it to the masses into admitting the whole conspiracy when they think the transmitter in Blue's head is being jammed by psi-blockers.
Blue: Them psi-blockers? They been down since you pulled the trigger.
Blackjack engineers a public confession in Fallout: Equestria - Project Horizons in order to expose Ahuizotl as a traitor to the rest of Meatlocker. Ahuizotl, however, is Genre Savvy enough to realize what's going on, and activates the rooms's hidden booby traps.
Ahuizotl: What? You don't seriously think I'd believe you'd want to do business with me? You're the saint of the Wasteland. I'm sure you're just here to chat up some evidence to take back to those morons. Probably got that PipBuck recording this whole conversation, don't you?
In Time Enough, Harry makes a man confess his crimes to him in a pub. The guy gloats that "No one will ever believe you. You've got a room full of drunks as witnesses." Alas, Harry was prepared for such an occasion... That is, an Auror and a reporter (Ron and Luna) were sitting nearby, both perfectly sober.
May the Best Friend Win, the first sequel to Rainbooms and Royalty, has this pop up during the climax: Twilight casts a spell that swaps one of her eyes with Rainbow Dash's, allowing her to see Twilight confront Trixie and Trixie admitting to acting like a total Jerkass to all of Dash's friends behind her back.

Forrest Gump: Inverted: During Forrest's stump speech during an anti-Vietnam rally that he somehow got convinced to go to, a large percentage of the speech involving things he was going to admit to the people about his experiences in Vietnam during the speech actually ended up missed because a Pro-Vietnam police officer pulled the plug on the mike, and the mike's sound output was only restored right when Forrest finishes up the statements. Of course, that didn't stop Abby Hoffman (who apparently heard the whole thing) from expressing sympathy about what happened in his experiences.
Hollywood Homicide: K. C. Calden gets Wasley to confess to murder, then reveals that he has recorded it.
The Saint: used in reverse. Simon Templar convinces the Russian president to confess to a fraudulent cold fusion project. After the president confesses in response to Ivan Tretiak’s accusations, the cold fusion machine works and destroy’s Tretiak’s credibility. 
The definitive example is in A Face in the Crowd. Political demagogue Andy Griffith has an official agenda for his adoring public but a more sinister agenda in private. When he starts to rave about this during a private conversation, Patricia Neal switches on the microphone so that Griffith's ravings are broadcasted.
Similarly, in Batman & Robin, Batman shows Mr Freeze that he didn't kill his wife by playing-back a video of Poison Ivy mouthing off about "As I said to Lady Freeze when I pulled her plug, this is a one-woman show!!" Hilarity Ensues (unfortunately off-screen) when Mr. Freeze later becomes Poison Ivy's cellmate at Arkham Asylum, as he (presumably) beats the living hell out of her.
In Home Alone 2: Lost In New York, Kevin recorded the "Sticky Bandits"' confessions with his toy tape recorder.

Colin Farrell's character in The Recruit uses his "Spartacus" program to transmit the gloating revelationAl Pacino's corrupt CIA agent to his superiors. Al Pacino emerges to find dozens of agents surrounding the building. However, in a subversion it turns out that Farrell was just bluffing, as the program wasn't able to get a signal. The agents still thought that he was the mole, and had arrived to capture him, not Pacino. However, Pacino believing they were here for him, delivers a rousing You Can't Handle the Truth speech and as a result is Hoist by His Own Petard. As the dozens of laser sights move from Farrell to him, he is given a moment to realize his error before committing Suicide by Cop.
One of the greatest examples of the Alpha Bitch, Courtney from Jawbreaker, spent the entire movie covering up her responsibility for a prank that got her friend killed. While holding a recordable greeting card, she says, "I killed the teen dream. Deal with it." Forgetting she had a finger on the recording button. One of her former pals discovers the card as she prepares to turn in for the night. Off she goes to deliver the goods. In the end, Courtney's recorded confession was spliced into the microphone as she gave her prom queen acceptance speech. And the Humiliation Conga begins.
In Star Trek VI: The Undiscovered Country, during Kirk's trial, an excerpt of his log entry saying "I have never trusted Klingons, and I never will. I've never been able to forgive them for the death of my boy." is shown as apparent proof of his motive behind Chancellor Gorkon's assassination. This fact is used later to implicate Lt. Valeris as a conspirator trying to sabotage Federation/Klingon peace talks.
Brilliant subversion (or perhaps Double Subversion) in the Eddie Murphy political comedy The Distinguished Gentleman. Murphy's conman-turned-congressman is secretly trying to prove that a more senior congressman is taking kickbacks from a lobbyist in return for blocking an investigation into the relationship between power lines and cancer. He claims in a committee hearing to have videotaped a meeting between himself, the senior member, and the lobbyist. When they grab him and pull him into the meeting and demand to watch the tape, they discover its a bluff- it was just an ad for the phone sex business he used to own. Secure that they've dodged the bullet, they launch into discussing their Evil Plan-as he surreptitiously tapes the whole thing and then plays it for the media as soon as they go back into the hearing.
In the "Weird Al" Yankovic film UHF, an evil network executive goes on a tirade about how little the community means to him and how stupid he thinks its inhabitants are. Eventually this gets broadcast to the entire community in question in place of the important message that the executive intended to make. Odd in that the opening line of the confession that we see earlier in the film (the rest is saved to be revealed later) and the full confession that we see later on are obviously from two different takes, since the line is delivered differently, the character is seated instead of standing, etc.
Waternoose:I'll kidnap a thousand children before I let this company die!
In Enemy of the State (1998), after the protagonists (Will Smith, Gene Hackman) have lost the original video record of a congressman's assassination ordered and overseen by the corrupt politician named Thomas Reynolds, senior advisor to the National Security Agency, they decide to bluff and try to trick him into incriminating himself during a meeting. Unfortunately, their plan of catching it on tape via a hidden mic fails, and they are captured by his goons. However, thinking he has won Reynolds then launches into a villain speech, confessing to the murder. Unbeknownst to Reynolds, one of his own NSA technical people gets cold feet and records the whole speech in their surveillance van, which is later used by the FBI as proof for the conspiracy to murder the congressman. Not that Reynolds cares anymore, because he's already dead at that point.

Cop cars show up at the dirty cop's house, he starts sweating and takes the brother hostage. The cops end up shooting him.
In the 2002 version of The Count of Monte Cristo, Dantes meets Villefort in a bath house and turns up the steam, obscuring much of the room. He then gets Villefort to confess to his crimes, at which point the steam clears away revealing the authorities who have been standing there the whole time.
Played straight in RoboCop (1987), when Corrupt Corporate Executive, Dick Jones, boasts of his many crimes in front of the eponymous hero. Of course, being part robot, Robocop visually records Jones' confession and plays it back for his bosses. Oops.
Jason Bourne pulled one on Ward Abbott in The Bourne Supremacy instead of killing him, which led to his suicide.
Parodied in Johnny English, where the protagonist accidentally switches the vital confession recording with candid footage of himself lipsynching to Abba in front of the bathroom mirror. In his underwear.
Happens in the finale of Gamer, right before he gets knifed in the gut.
In Max Keeble's Big Move, Max is called into the principal's office. The guy rants about he doesn't care about the school because he's using 97 percent of the money to build a big football stadium and about 1 percent for the school (2 percent is on breath spray). Max turns on the camera that the principal uses to make the morning announcements and the entire school is shown just how much of a slimeball their principal is. Needless to say, he gets fired.
Conventionally executed at the end of the Neill Marshall film Doomsday. The villain Canaris believes he's gotten away with everything, and explains his plan to heroine Eden Sinclair, and then returns to the control center and discovers that Sinclair recorded his confession and is having it broadcast to the world. We even see her setting her wrist device as she approaches the conversation with him.

Safety Patrol had the main characters expose that Scout Bozell was framed, and that it was the entire Safety Patrol and the lunchlady who were the true instigators of the fire by arranging for Weird Al Yankovic to sing the revelation with the tape being played throughout his concert. As soon as this was exposed, pretty much the entire Safety Patrol was fired, and Scout was reinstated with a new safety patrol team, and the Lunchlady was arrested partially for this reason.
In Mission Impossible II, Vlad infects John McCloy with the Chimera virus, and will only give him the antidote if he confesses to leaking it. However, it's all a trick, and Vlad was really Ethan in disguise with a tape recorder hidden under his coat
Used to in the live action Yogi Bear movie when the corrupt Mayor Brown's attempt to dispose of an endangered turtle that's existence would stop his attempts to close Jellystone park. Turns out Boo Boo's bowtie camera (which previously in the film had been put on him for a nature documentary about him and Yogi) recorded Brown stating both this and how he doesn't care about Jellystone at all. The heroes then play it during his election promo, revealing what a slime ball he is to the entire city. To make matters worse, said turtle gets on stage at that very moment, confirming the confession. He and his Chief of Staff are arrested on the spot.
In The Dark Knight Rises, Bane reads out Gordon's speech where he reveals the conspiracy to protect Harvey Dent's good name. (Inverted, as here it's the villain enforcing the hero's confession than the other way round.)

In Artemis Fowl: The Arctic Incident Briar Cugeon gloats about his plan to kill Opal Koboi as Foaly records the conversation on Artemis' computer. Notable in that the whole thing doesn't get played at once. Select snippets of it are sent to the various people involved, one at a time, in various ways.
"The Dying Detective", in which a concealed Watson overhears the gloating of a villain who thinks he's given Holmes a fatal disease.
"The Adventure of the Mazarin Stone", with a minor twist: Holmes didn't need the thieves to confess to stealing the missing diamond, as he had collected all the evidence he needed to convict before the story started. What he needed was to trick the thieves into saying where they had hidden it.
During Timothy Zahn's Thrawn Trilogy in the Star Wars Expanded Universe, Princess Leia gets to do this to Smug Snake Borsk Fey'lya - the ship they were in went to arrest Han, Luke, and Rogue Squadron, and when an Imperial Star Destroyer showed up and the Rogues started flying cover, Fey'lya's ship and escorts started to abandon them and flee, nominally to get back and warn the Republic. Leia goaded him into admitting that the only use soldiers could have to a politician was political power, and his political enemies were his enemies in truth - the people on his ship and flying as his escort were his most ardent supporters, fleeing and letting his 'enemies' die could only benefit him. His supporters promptly mutiny and turn back to save the others.
In The Sea of Monsters, the second book in the Percy Jackson and the Olympians series, Percy tricks Luke into confessing his crime of poisoning Thalia's tree to the entirety of Camp Half-Blood through an Iris-message, also proving Chiron's innocence.
In "Gone Too Far", a Transformers: TransTech text story, our heroes manage to use this to their advantage. It's unwise to admit you framed someone for murder when they're a communications 'bot who records everything they hear.
And in the Transformers: Shattered Glass story "Blitzwing Bop", Soundwave tricks Blaster into confessing a crime in front of a Cybertronian officer.
At the end of the Alina Adams mystery Death Drop, the heroine engineers a situation for the murderer to make a confession to a certain acquaintance of his with a reality TV show in a storeroom full of cameras; he didn't check to make sure none of them were on.

Averted in Seven Days in May — even with insurmountable evidence laid out before him, the antagonist never makes any explicit admission of guilt.
In the Andrew Vachss Burke book Dead and Gone, Burke manages to get the Big Bad to admit his planned duplicity while a gadget is transmitting his words to the mercenaries supposed to be guarding him.
In the Doctor Who New Adventures novel The Dying Days the Doctor pulls off one of these on the alien warlord who has taken over Britain and declared himself King. After tricking him into breathing in helium the Doctor then displays the whole conversation as a giant hologram in the sky with the villain's (squeaky) rant broadcast all over the world.
The Doctor: I think you've just made your abdication speech Your Majesty.'
At the end of Embedded, Lex Falk is able to talk Tedders into admitting everything about the alien artifact on the colony planet Eighty-Six, which is what the Bloc and SOMD armies are fighting over. Tedders admits this because Falk is in control of the body of Nestor Bloom, a SOMD soldier, and she feels that "Bloom" needs the whole story, even while the SOMD is trying to cover up the whole thing. She doesn't realize that Falk is there until he openly admits that everything that Bloom is seeing and hearing is being transmitted live to the various news agencies.
In one Star Trek: New Frontier novel, Captain Mackenzie Calhoun defeats an evil alien leader this way.

However, knowing that such a confession would be thrown out for being made under duress, Emily instead reveals the truth to Charlotte about her father's crimes, plants a hidden camera on her jacket and releases her (all while concealing her identity). Charlotte then returns home and immediately confronts Conrad about framing her biological father. Conrad flips out, declares Charlotte an ungrateful bastard and threatens her to remain silent, confessing to everything in the process. As a final gesture, Nolan turns on the TV at Grayson manor just in time for Conrad to see that his confession has been broadcast on live TV for everyone to see- thus clearing David Clarke's name and sending Conrad to prison.

Martha and Jack had planned this the entire time.

Coronation Street: Subversion: Roy and Haley are trying to adopt an unhappy child but his abusive father won't let them take him without lots of cash exchanging hands. They try to trick him into confessing, but don't quite manage it. They hide the recorder under a newspaper and sit him next to it, then try to get him to remind them what the plot of the arc is. After a few hours he's fairly pissed off and wants them to get to the point of why they asked him to come over. Roy tries to pay him a meager sum in exchange for his signature on the papers. The guy freaks out, barking at them that he wants lots more money or they'll never see the kid, and how he'll get violent if they ever waste his time like this again. It's at this point that the recorder runs out of tape and makes a whirring noise. He finds it, smashes it, threatens them some more, and demands yet more money.
One episode combines this tactic hilariously with Gaslighting: the team engineer the villain of the episode to break down and admit to her boss (and, unknowingly, also through her store's speaker system) that she's been covering up a toxic waste spill (which never actually existed) - after which she goes on to detail the various other evil things she's also done.

In Primeval, when Christine has taken over the ARC, she's exposed when her rude remarks about the Minister are taped, and sent to him by Beckett, saving everyone's bacon, although earlier, Beckett had seemed to be Christine's loyal minion. It's hilarious!
Episode "Enemies," when Faith believes Buffy is tied up and Angel is his evil alter ego Angelus, she tells them about the Mayor's plans — only, Buffy isn't tied and Angel is still his soulful self.
In "Intervention" Spike tells his Buffy Sex Bot that he'd die before giving up Dawn to Glory, unaware that it's actually Buffy pretending to be the bot. Realising that Spike's Heel-Face Turn is genuine earns him a kiss and Buffy's trust from then on.
In the season 4 finale, Michael Garibaldi (and the other main characters) are recreated as illusions 500 years in the future to blacken their characters. Garibaldi's illusion then proceeds to hack into the system, broadcasting the discussion between him and the scientist who created the illusions into the aether, while convincing the scientist to explain their side's plans on the virtue of being an illusion. It was awesome.
Much earlier, in the season 1 episode "Eyes", Sinclair executes the psychic version of this trope by taunting EarthForce agent Ari ben-Zayn until his hatred and resentment of Sinclair (that was the motivation behind his investigation and attempted coup) was revealed to the telepath he brought with him, who then helped Sinclair, Ivanova and Garibaldi to take him down.

Happens frequently on Law & Order. David Cross famously got in hot water for badmouthing his own guest role on L&O and the somewhat lazy writing — leading to severely constrained opportunities for acting — of having the villain just break down and confess everything to the cops after a few prods.
Vanessa does this to Blair on Gossip Girl in Enough About Eve. In season 6 Chuck attempts to do this to his father,unfortunately Bart sees right through it.
In Torchwood: Children of Earth, Torchwood record a meeting of the British cabinet in which they decide to give the 456 ten percent of the children and agree on the way to select the ten percent.

The government do as they're told, but later yet, it is implied that further damning information will indeed be made public.
In the Doctor Who episode "Day of the Moon", the Doctor and friends pull a variety of this on the Silence. "You tend to my wounds. You are foolish. You should kill us all on sight!" rants a wounded Silent. The last sentence is later replayed as one of these during the live footage of Neil Armstrong's first step on the moon, all around the world, reinterpreted as a hypnotic command. The humans do as they're told. Even better, since the confession was spliced into one of humanity's biggest historical milestones, the Doctor ensured that humans will continue to see the message for a looooong time.
A variation takes place in The Twilight Zone episode "The Obsolete Man". When Romney Wordsworth (Burgess Meredith) was sentenced to death by the totalitarian State for "obsolescence" (i.e. collecting books and professing his belief in God in a world where both books and religion are outlawed), he requested that his death be administered by a time bomb and that his death be televised. When the judge who sentenced him visited him before his execution to gloat, Wordsworth secretly locked him inside with him, so the judge would be executed with him. Seconds before the bomb went off, the judge cracked:
Judge: In God's name, let me out!
Wordsworth: Yes. In God's name, I will let you out. (The judge survived, but was now brought up on charges of obsolescence for begging for his life "in God's Name")
Parodied in The Thin Blue Line, where the chief admits to Raymond Fowler that he faked some evidence. Raymond the triumphantly pulls out a rather large tape recorder from his pocket. But when he tries to play the confession, the tape just runs the workout-training that used to be on the tape. Another policeman then shows that you have to press both record and play at the same time to start recording, "I don't know why either". As an added bonus, the recorder is turned on during that demonstration, resulting in it recording some fierce Innocent Innuendo between Raymond and his ex-girlfriend. And the tape belonged to Raymond's wife, and she uses it for her workout at the end of the episode....
On Desperate Housewives, Tom's evil love child Kayla gets Lynette arrested by burning herself and calling Children's Protective Services, saying that Lynette did it.

While he's bragging to Mama in his office about how he "bagged every good-looking checker in the Tri-State Area," Mama turns on the store's PA system, letting his confession be heard by all the employees and customers. (And when he lunges at her/the microphone, beats him up with her purse while screaming into the mic.)
On Chuck, Magnificent Bastard Daniel Shaw is a good way toward taking over the CIA and has already made all the heroes look insane or murderous. Chuck sneaks into his private office during a meeting of agencies from all over the world, and makes Shaw think his big plan was tricking Shaw into alerting the leaders of the evil organization The Ring, getting them to leave the conference and thus reveal themselves. Shaw points out that they're still considered outlaws who no one will listen to, and Chuck goads him into gloating about being a Ring agent, plus murdering Chuck's father. Then Chuck reveals that their whole conversation has been broadcast to everyone at the conference.
On NCIS, Ziva gets a suspect to confess that she is Iranian intelligence by letting her think she is beating Ziva up. Ziva was wearing a mic and got the confession on tape.
Subverted in the episode "Mr. Monk Meets the Godfather", where Monk attempted to extract a confession out of the killer (a man who stole five double headed pennies from the U.S. Mint) for the FBI to hear (he was wearing a tie that contained a bug), but the confession did not come through due to the bug being damaged (Monk had the tie drycleaned due to a stain he accidentally got on the tie during an attempted sting on the Mafiosos for attempting to attack a gang earlier).
A Double Subversion occurs during the episode "Mr. Monk Is On the Run Part 2". Natalie attempts to record Dale the Whale's confession on tape, but he knew long before she attempted to do so that she was going to try that, and did not confirm that he was attempting to frame Monk. However, he did tell her to record his message to Monk about switching places with him... and invoked the trope on himself anyways by having her record while his computer was on a weather map on Riverton, causing Monk to deduce exactly what Dale was planning.
In an episode of Andromeda, Dylan Hunt is accused of murder. He finds out he was framed by people he has never met before. He then tracks down the last one, who laments losing his friends but brags about framing Hunt. Hunt, of course, is keeping his Comm Links channel open for Rommie to record and broadcast to the authorities.
Episode "The Curse of the King Kamehameha Club", Thomas Magnum does this to an unscrupulous TV reporter with her video camera.

Starsky and Hutch force two FBI agents to confess that they've been trying to unofficially intimidate S&H into backing off of a case. When the door swings open to reveal their boss has been listening in, he is not best pleased.
Episode "Demons" plays this entirely straight: Castle and Beckett confront the Murderer of the Week by themselves in a spooky old mansion, the murderer gets the upper hand, tells them everything because he's going to kill them anyway, and then they tell him they set up a recording device in the room and cops were waiting right outside the whole time.
This is (at least) the second time Castle has employed this trope. The previous was only two episodes prior. Ryan wired up the youngest kid in a crime family and had him try to get a confession out of his brother for killing his tutor. He gets it, with his brother pointing a gun at him. Cops bust in, and the kid gets shot. He's not quite dead. The shooting was a ruse to get the kid into protective custody.
Used by Patrick Jane in The Mentalist against another 'psychic' to get him to leave a woman alone.
JAG: In "Killer Instinct" (season 6), the defendant is a petty officer on an Aircraft Carrier suspected of murdering a subordinate (by throwing overboard at night), because they were incompetent at their jobs. One crucial piece of evidence is not admissible in court because the ship's CO did not have probable cause for issuing a search warrant, and this necessitates a different strategy from the prosecution. Harm does the standard Perry Mason Method, knowing beforehand that the defendant will not fall into the trap and make him overconfident. And when Bud later has his turn to question him, he begins by asking the defendant several questions that Harm had asked earlier, then proceeds to make several other basic errors before dropping his notes in mid-question, and finally drives the pedantic defendant into a rage, before revealing that he was Obfuscating Stupidity and it was all part of a plan.

Unfortunately Hanna doesn't realize until it's too late that "someone"(Mona acting as "A") had turned on the intercom so Kate,Kate's friends,and everyone else outside hear every word she said.
Kamen Rider Fourze presents an inverted version of the trope, in which a Monster of the Week is the one who exposes a good guy to the public. For more context, the Monster in question is the Chamaeleon Zodiarts, and as its name implies, is able to use camouflage. It uses this ability to film the school's Alpha Bitch, Miu, ripping the gifts that the students at the school made for her and showing just how much she doesn't care for them in the slightest. The Zodiarts then proceeds to show this film to everyone during a contest to see who would be the queen of their school. It's because of this that causes Miu to take a Heel-Face Turn.

Revolution: This is how the heroes finally take down the Patriots at the end of Season 2: after kidnapping President Davis, they're ambushed by Patriot soldiers. When Davis gets free, he flies into a rant about how he represents the true America, and how he's going to get Texas and California to wipe each other out for him. However, when he gives the order to have the heroes shot, it turns out that the "Patriots" are Texas Rangers, and the de facto leader of Texas is in the other room — this whole scenario was a setup to provide Texas with undeniable proof that the Patriots were playing them, and results in Davis' arrest and Texas declaring war on the outnumbered Patriots.

Ace Attorney - In the final case of Apollo Justice you put all of the clues together and they point to Kristoph Gavin. That person gloats because they don't believe the evidence to be strong enough to convict them, and they believes that's the only way you'll be able to save the defendant... then they're reminded that the trial is the first one in which a jury gets to determine the guilt or innocence of the defendant, and the defence believes that they've given the jury enough reasonable doubt. This cues the start of a Villainous Breakdown as the guilty party rants, raves, and insults the members of the jury...who are all watching, live.

I was called upon to serve the greater interests of humanity! Personal power was never my goal.

Harvey Bullock, and were waiting for Batman to give the signal to arrest them once Joker blabbed about where he was keep Catwoman hostage.
In "Riddler's Reform", Batman had just escaped a death trap set by Riddler, who's desperate to learn how he escaped. Desperate enough to offer to confess his crimes.

An episode has Timmy proving to the authorities that assign fairy godparents that Vicky (who had taken Cosmo and Wanda from him) was happy (and thus no longer needed the two) with a tape recorder. A manipulated tape recorder, at that. One side is her talking, the other is a faked voice. When she protests the fake voice, he reveals he recorded her protest. Probably counts as Karmic Death, as Vicky used the same trick earlier.
Another episode has Vicky and Timmy trying to frame each other over the use of a special voice-changing microphone and a pirate radio station. Timmy had been using the microphone to manipulate the town's parents into spending more time with their kids.

In a variation, an episode of Superman: The Animated Series had Lois tricking a crooked cop to confess to framing a man on death row for his murder... with Superman right outside, using his super-hearing to get every detail.

In the thirteenth season premiere of South Park, Kyle turns on the microphone backstage at a Jonas Brothers concert, causing a live world-broadcast of the confession of a long-term plan to exploit the purported myopia of devout Christians by secretly selling sex to girls under the guise of good, clean, family-friendly entertainment. And just for that extra South Park kick, the person he engineers this confession from is Mickey Mouse. Didn't quite work, as Mickey was so powerfully homicidal that the world just knuckled under to him, waiting until his rage was spent and he went back to sleep.
Spoofed in Drawn Together. Spanky Ham and Captain Hero were abusing a superhero-versus-villain gambling book, with Spanky Ham betting thousands of dollars for the monster and Captain Hero deliberately failing very miserably, when Captain Hero was overcome by greed and decided to do it himself.

Unfortunately for him, his son had other plans. His son engineered a media circus with complaints about his polluting his stationed country's water supply, getting his father angry enough to disintegrate the skin grafts used to contain his mutated form, Blight, on live TV, which meant they now know who the radioactive guy who was committing various crimes was, including Terry McGinnis.
Angelica Pickles, due to not liking Chinese food and wanting other things, used a prototype voice changer that her uncle invented to get several things, such as sweets, a Cynthia dollhouse (that her father promised to get if she was well behaved), and a faux surprise party for her. When Tommy's parents came home, they were about to take away the grampa's teeth (as they threatened to do so if he didn't supervise the kids), Angelica attempts to quell it, with Tommy activating the voice changer and placing it right near her mouth while she is speaking, causing them to realize just how Angelica managed to trick them big time. Needless to say, she has to eat the stuff she ordered as her punishment, and her uncle puts away the voice changer in a dark cupboard, stating that some things were better off not being invented.
In another episode, Angelica, while backstage at her favorite kids show, was nominated as one of the new on-stage kids, and she and the other nominees listened in on the show host's conversation with her second-in-command, about her audience, and she overheard her say the secret word, and was the only one who actually heard it. She then won, and she also thought she won due to hearing the secret word (which is implied to be a very, very dirty cussword, due to various placements of cutoffs with a person honking his horn or someone jackhammering, or in the case of her repeating the word to her mom, a very loud anguished scream being heard in the distance), her parents, after initially grounding her, eventually allow her to go to the backstage showing of the show, under the condition that she not say the word. In her usual manners, she manages to trick the show hostess by making her lose control of her temper to utter that exact swear word on the air, to the shock of all watching, and Angelica then states that she proved that she did actually say it. The show hostess was later fired, and replaced with her second in command.
Family Guy in the episode "One If By Clam, Two If By Sea". Lois tries to uncover insurance fraud by hiding her friends in the room and getting the villain to confess.

Spoofed in an episode of American Dad!, where school announcement readers getting Drunk with Power, tricked into making an Engineered Public Confession, and losing their position is apparently a regular occurrence. Each one lasts even less time than his predecessor: Steve goes through this in a few days, then his friend Snot goes through it in one day, then their friend Barry snaps the second he sits down at the desk.

Lamarr hears everything and subjects Roger to Doug's punishment instead.
Often, whenever a public figure or celebrity decides to confess to committing an action, it is only because someone else has discovered it and is about to release the details. A prime example is Tom MacMaster, who decided to reveal that his blog A Gay Girl in Damascus was a fraud only after his identity was uncovered by Electronic Intifada.
Roger Clemens tried to do this by secretly taping a phone conversation between former trainer Brian Mcnamee so that he would admit that Clemens did not take HGH; all it proved was that Mcnamee was either telling the truth, or not a complete idiot.
Former Hungarian prime minister Ferenc Gyurcsány held a private speech telling his own colleagues that they had lied to the people about the state of the country in order to win the elections, and how they "fucked up" and needed to get themselves together to make things work again.

A recording of (former) Illinois Governor Rod Blagojevich was leaked. In it, he discussed his plan to sell the Senate seat vacated by newly-elected President Obama to the highest bidder. Later, he would apologize for swearing so violently in the tape. He would eventually be convicted of (among many other things) misuse of power and corruption.
Note that of Illinois' ten governors between World War II and Blagojevich's term, five were tried for corruption and four were convicted. Of them, Blagojevich was the only one to be impeached and removed from office (the others had all resigned before things got that far).
Linda Tripp, as stated above, taped Lewinsky's confession. Though she caught a lot of flack for it, it should be noted that a previous Clinton mistress had confided in Tripp and when Tripp had to go public with it, she was smeared in the press, and poked fun at with regard to her weight as in the later example because it was her word against the president's. Call it Crazy-Prepared, but it's not that crazy under the circumstances.
WikiLeaks and Anonymous seek to be the Internet version of this. In fact, the HB Gary Federal leak is a fitting example. Edward Snowden has also ventured into this territory.
The "Teapot Tapes" in New Zealand. Ironically the politicians at the centre of it have accused the media of "News of the World"-style tactics. Initially it wasn't completely played straight - the tapes are in the hands of the police after the initial controversy, and the cameraman who made the original recording is fighting for his reputation and bank balance in the courts. In early 2012, however, it was subsequently inverted when the recording was leaked onto the Internet.
Still in New Zealand, investigative journalist Nicky Hager's 2014 book, Dirty Politics, was sourced from secret correspondence of a controversial blogger given to him by a suspected hacker. To Hager's supporters, this trope is played straight; to his detractors, he's a recipient of stolen property. On top of that, the hacker who supplied the documents to Hager leaked further dirt on Twitter.
Also, Tennessee radio talk show host Thaddeus Matthews made racist as well as rude comments towards one of his guests, all caught on tape.
The British Holocaust denier David Irving holds the unusual achievement of self-Engineering his confession. When the Jewish-American historian Deborah Lipstadt wrote in her book Denying the Holocaust that he was a Holocaust denier and had deliberately falsified historical evidence, he sued her for libel. Unfortunately, Lipstadt's lawyers asked Richard J. Evans, one of the finest historians in Britain (if not the whole world) and a team of experts to go through Irving's work with a fine-tooth comb and found that it was patently obvious that he had lied and cheated in order to show Nazism in a better light. At the end of a humiliating trial (ironic, because Irving had hoped to humiliate and financially ruin Lipstadt by suing her in the first place), he accidentally addressed the judge as "Mein Führer." Hilarity, and a well-deserved comeuppance, ensued.
Former British Prime-Minister Gordon Brown, after having a discussion with a Labour supporter named Gillian Duffy got into his limo, smiling and waving and then drove off, telling his driver in private: "That was a disaster. You should never have put me with that woman. Whose idea was that? Ridiculous. She was just a bigoted sort of woman. What's that noise?" Turns out, his microphone was still on the lapel of his jacket.
The infamous video of Mitt Romney saying 47 percent of US citizens don't pay taxes and he wouldn't bother trying to sway them to his side.
Attempted Defied by the Illinois Eavesdropping Act. Attempting to catch on recording corrupt officers is made a felony. Courts have responded in various ways to challenges to the law, ultimately resulting in the law being declared unconstitutional by the Illinois Supreme Court.
The "Mister Big" sting used by Canadian law enforcement (where it is legal, unlike in the US) creates this situation. If the police are confident they are know who the murderer is, but don't have enough evidence to be confident of a conviction, they set up an elaborate operation where an undercover officer will befriend the suspect and gradually convince the suspect that the undercover is a member of some organized crime group, eventually leading to the suspect witnessing supposed crimes and sometimes becoming a participant in them, all faked and staged by the authorities. If it works, they reach a point where the suspect wants in on the operation and is taken to meet the boss ("Mr. Big"). The suspect is told that the only way into the organization is to prove they won't lie to the Boss, and the way they can prove that is to reveal details about the murder, with the Boss insinuating that he already knows all about it and won't tolerate being lied to. Ideally, the suspect then confesses to the crime (while being secretly recorded) and reveals things only the real killer could know, and sometimes more evidence the police didn't know about.
