[[caption-width-right:350:[[TheCityHunter Here's how to dispose most incriminating evidence. By burning.]]]]

Our hero, or another good character, has come into possession of some evidence relating to a crime. However, instead of turning this evidence over to the proper authorities, the hero destroys (or withholds/hides) the evidence.

Why? Well, there's a number of reasons. For instance:

* The evidence could incriminate someone else who the hero likes and doesn't want to see punished.
* The evidence, if made public, will ruin the victim's life (or the life of someone involved in the crime).
* The hero is being blackmailed by the BigBad or an associate.
* The hero would be incriminated by the evidence.
* The evidence contains information which would exonerate another villain who is on trial for another crime.
* The evidence, if involving a dead person, might [[NeverSpeakIllOfTheDead cast a bad light on their memory]] -- and the hero was a good friend/relative/lover of the dead person.
* The evidence is entirely worthless -- it's too late to act.
* The hero wants to [[VigilanteMan punish the bad guy himself]].
* While the evidence could get the bad guy put away or otherwise punished, it would cause scandals and create chaos for a lot of people, some who may be entirely innocent.
* The evidence would reveal [[DirtyBusiness an ugly truth]] about a past event that the public perceives as a good thing, and the hero wants the event to stay a good thing.
* The criminal committed the crime for a [[IDidWhatIHadToDo good]] [[ScrewTheRulesImDoingWhatsRight reason]], and in retrospect the hero agrees that the act was justified.
* The crime involved the murder of someone who was [[AssholeVictim a truly terrible person]], and the hero doesn't want the evidence revealed, since it would result in someone going to prison for something he doesn't think of as a crime.
* The hero is currently [[{{Frameup}} on the run]] or at least [[HeroWithBadPublicity not on good terms with the local authorities]], so he can't give the evidence to them without being captured/killed/arrested.
* The hero is actually [[TheReveal the villain]].
* The hero believes that the criminal is genuinely repentant and [[GoAndSinNoMore need not be punished further]].

Whatever good intentions the hero may have had, destroying the evidence will probably have bad results -- a villain could walk free, for instance. May result in a WhatTheHellHero.

[[folder:Comics]]
* The ''ComicBook/SinCity'' story ''The Big Fat Kill'' involves destroying a [[ItMakesSenseInContext decapited head]] in order to avoid a MobWar between the mafia and cops with the local prostitutes caught in the middle. The ending goes one step further by [[spoiler:killing every possible witness to the murder of said head's owner]].

[[folder: Fan Works]]
* In ''FanFic/DirtySympathy'' Apollo disposes his gun and the bullets from LeTouse's murder into the sewer to hide that [[spoiler: Machi]] killed him.
* ''FanFic/GraduateMeetingOfMutualKilling'': Mishio Matsukaze had managed to write in a notebook everything he had found about the Mastermind behind the game, in case he died. [[spoiler:However, what he didn't expect was that the person who killed him would find the notebook by chance AND would be aligned with the Mastermind. The notebook was destroyed due to its incriminating nature towards the Mastermind.]]

[[folder:Literature]]
* In the WhateleyUniverse, Kodiak destroys tapes of [[spoiler: the Don (and probably more of the Alphas) abusing and raping Skybolt and Cavalier, who were MindRaped into being obedient slaves]] because he knows that should the tapes get out, sooner or later the entire school would see them- and any chance of [[spoiler: Skybolt and Cavalier]] having a normal life once they get released from the psych ward would be ruined.
* There's an accidental case in ''[[Literature/PhryneFisher Dead Man's Chest]]'' by Kerry Greenwood. At a wake held for a dead woman, Phryne steals a pillowcase dropped by a maid that she finds to be suspicious- it [[spoiler: has teeth imprints and a stiff patch, indicating that the old woman was murdered by being smothered with the pillow.]] At the end of the novel, Phryne's maid Dot washes the pillowcase and returns it, not realising that it was important.
* In one of the ''Literature/LordPeterWimsey'' stories, he discovers the identity of the murderer, who was a SympatheticMurderer, and tells his friend, a policeman, a hypothetical story of who he thinks is the murderer and how it happened (he's actually telling him the real story) but since another has confessed and later killed himself, the policeman tells him to let it drop. Wimsey later reflects that he could, if he wanted, prove the case, though he doesn't want to.
* In ''[[Literature/{{Gor}} Players of Gor]]'', Cabot learns of a plot by Cos, Tyros, Brundisium and [[SixthRangerTraitor certain factions in Ar]] to attack Ar. He gets the evidence, then learns that it's actually happening right now. The evidence is now worthless so he burns it. Plus he plans to exact his own revenge.
* The ''Literature/HoratioHornblower'' short story ''[[http://en.wikipedia.org/wiki/Hornblower_and_the_Widow_McCool Hornblower and the Widow McCool]]''. The British occupying forces and Irish rebels have recently achieved a fragile peace in Ireland. Hornblower discovers letters to rebels not known to the authorities. If he turns the letters over to the authorities, they'll go after the rebels and cause another outbreak of violence. He decides to throw the letters overboard instead.
* In the ''Literature/{{Discworld}}'' novel ''Discworld/MenAtArms'', Captain Carrot destroys the evidence that [[spoiler: he's the rightful king of Ankh-Morpork,]] because he doesn't think it needs a king anymore.

[[folder:LiveActionTV]]
* In ''Series/VeronicaMars'', Logan comes into possession of [[spoiler: the sex tapes of his girlfriend and his father]], and he destroys them so [[spoiler: they wouldn't be seen in court and ruin Lilly's memory.]]
* In one episode of ''Series/{{NCIS}}'', Gibbs [[spoiler: switches tissue samples so that it will appear that a body they're trying to identify was that of a dead Marine- the Marine (who is dead) had had a kidney transplant from a friend, who was still alive. Because you can't be a Marine if at some point in your life you donated an organ]], the Marine, if this became known, would have to quit- which he ''really'' didn't want to do.
** Another ''Series/{{NCIS}}'' example. In the end of one episode Gibbs realizes that a bad guy was killed with the prayer beads of a man the bad guy himself murdered, a marine and the son of a local Imam. Gibbs knows that this means the marine's father killed the bad guy to avenge his son's death, and the Imam should be arrested for murder himself. But when Ziva mentions that the prayer beads belong to the original victim Gibbs denies it, and she let's it pass.
* In a season of ''Series/TheDukesOfHazzard'', the phrase "The boys got off, because there wasn't any evidence" is about guaranteed to occur in at least a third of the episodes. Frequently the lack of evidence is a result of it being sunk in a pond, set on fire, blown up or in some other fashion destroyed. Sometimes the destruction is even intentional.
** Riffing on the ''Dukes of Hazzard'' one, one time they were being chased for having made moonshine but got off because they used it as fuel for [[CoolCar the General Lee]] and had run out of "gas." (Which I guess would be another EatTheEvidence example, for a given definition of "eat.")
* At the end of at least one episode of ''Series/JonathanCreek'', ("[[spoiler: The Scented Room]]" is the one I'm thinking of, although it ''may'' also have happened in "[[spoiler: Devil's Chimney]]") the title character lets the culprit go, on the grounds that they're not really that bad.
* ''Series/{{Dexter}}'' has been known to mess with or destroy evidence to en*sure that particularly bad criminals go free... so he can hunt them down and kill them instead of letting them have a government-sponsored vacation at prison.
* In the season one finale of ''Series/InPlainSight'', Mary hides cocaine from the police and Marshall Service to protect her little sister. The final shot of the episode is of the back of a line-painting machine on a football field, implying that this is how she got rid of the evidence.
** Actually she fully believed that the drugs were in those cases. It was her boyfriend (who was a baseball player) that got rid of it that way.
* ''Series/{{CSI NY}}'': "The Fall." Don Flack's mentor, Moran, finds out that his son was involved in the robbery of a bodega. He subsequently disposes of the incriminating pop can he finds to keep the boy out of jail. This results in BrokenPedestal and Mac and Flack having to arrest him.
* ''Franchise/{{Dragnet}}'' had it once or twice. One episode involved a bookmaker destroying his paper trail, which was written on flash paper, a quick burning type of paper. Friday luckily stopped him before it all went up in flames.
* ''Series/AllMyChildren'': After getting [[RapeIsASpecialKindOfEvil raped]] by Michael Cambias, Bianca is severely traumatized and burns all the physical evidence. Unfortunately, when he is later taken to court for it, Bianca's destruction of the evidence only ensures that Michael gets OffOnATechnicality long enough for Bianca herself to confront him and shoot him dead in self-defense.
* In the infamous episode "In The Pale Moonlight" of ''Series/StarTrekDeepSpaceNine'', Captain Sisko basically confesses to his personal log that he was an accessory to a murderous conspiracy to drag the Romulan Empire into the war against the Dominion that the Federation and Klingon Empire weren't doing too well in. The most self-damning thing to him is that [[ICanLiveWithThat he thinks he can live with it.]] He then tells the computer to delete the entire log entry.

[[folder:Theatre]]
* ''Theatre/LovesLaboursLost'': The King and three lords in his attendance take an oath not to woo any women for 3 years; then [[HilarityEnsues some women show up]]. The King and two of his lords are caught writing love notes by the fourth who berates them; then the love note that ''he'' wrote is brought forth by some rustics, so he tears it up before anyone else can read it. (In a production I was recently involved with he even tried to EatTheEvidence.)

[[folder:VideoGames]]
* ''VideoGame/HeavyRain'': [[spoiler: Scott Shelby burns the evidence he finds relating to the Origami Killer...because he ''is'' the Origami Killer]].
* ''VideoGame/{{Persona 4}}: [[spoiler: Adachi, who is both the murderer and a detective working on the case, admits to destroying certain bits of evidence.]]
** And in the EnhancedRemake the player character can choose not to pursue [[spoiler: Adachi, given his Social Link has been maxed out. If the player confronts him after it's too late, he can choose to destroy the remaining evidence and form an alliance with Adachi.]]
* In ''VideoGame/FinalFantasyX'', Tromell destroys the sphere revealing that [[spoiler:Seymour killed his father]] because "The Guado deal with Guado affairs".

[[folder:VisualNovels]]
* Done multiple times in the ''VisualNovel/AceAttorney'' series, usually by the defendants. Often they're trying to protect someone they care about from incrimination, even at the cost of their own freedom:
** In case 1-5, Lana Skye deliberately distorted evidence relating to the SL-9 incident partially in order to get Joe Darke convicted, but mainly to [[spoiler: prevent her sister from being charged with murder]]. Later, Phoenix doesn't want to present a certain piece of evidence for the same reason - it implicates someone he doesn't want to see get in trouble. [[spoiler:He does present it later when it becomes the key piece of evidence to implicate the guilty party, who is the only one who could have known about its significance and removed it]].
** [[spoiler: Phoenix Wright]] himself does this in 3-1 by [[spoiler: eating Dahlia's locket.]]
** Special mention to [[spoiler: Detective Badd]] in ''VisualNovel/AceAttorneyInvestigations'' who destroyed evidence relating to [[spoiler: the Yatagarasu. As head of the investigation he was in a perfect position no traces were ever found at the crime scene.]] Why? [[spoiler: He ''was'' a member of the Yatagarasu.]]
** Late in Case 1-4, [[spoiler:Manfred Von Karma]] destroys most of the critical evidence you have, but fails to get [[spoiler:the bullet from the Dl-6 Incident]], which leads to his undoing. He even says that his accomplice. [[spoiler:Yanni Yogi]], should have burned the letter he received.
