Jury and Witness Tampering

Go To

The prosecution's case depends on certain key witnesses' testimony in order to get a successful conviction. Or, all the evidence is already in place and all that's left is for the jury to say that the person is guilty. But — out of nowhere, a witness changes his/her testimony or refuses to testify at all, or the jury either gives an unexpected verdict or becomes deadlocked on what's supposed to be an Open-and-Shut Case. What just happened?!?

Turns out the witness was approached outside the courtroom by the defendant, or a representative of the defendant, and was coerced into changing their story or not showing up to testify, either through monetary offerings or threats to the witness or their loved ones. In the case of the jury, it may be that at least one member was similarly approached and "persuaded" to sway their fellow jurors in a direction more favorable to the defendant.

What we have here, then, is Jury and Witness Tampering, a convention that's common in many a Police Procedural and Law Procedural show, with subsequent investigation by the police involved in the case revealing that this trope was in effect outside their (and the viewer's) knowledge till well after the fact.

A Common Nonsense Jury may be created because of this. A Rogue Juror may have this as their reason for going against the grain (not all the time, though). If this trope results in a witness testimony being changed or is part of a larger Frameup plot, that may result in an innocent person going to jail.

In real life, witness tampering is a criminal offense that falls under obstruction of justice; plus, when witnesses lie about crucial details or outright change their testimony while on the stand, in legal terms that's called committing perjury, and can likewise result in jail time regardless of the reason. Where juries are concerned, this trope is why prospective jurors are warned not to discuss the case outside the courtroom for the case's duration, why their identities are kept secret, and why they're warned not to utilize any information other than what's presented to them in court for the purpose of deliberation. (If outside information is given to a juror to help influence a verdict, the case will result in a mistrial.) This is a particularly huge problem in domestic violence cases; witnesses suddenly recanting or turning uncooperative after previously being highly consistent and cooperative is a very regular phenomenon there, and the usual assumption when it happens is that the accused called, messaged, or otherwise found a way to contact the witness and cajoled or threatened them into silence.

Compare He Knows Too Much, when the defendants or their associates take the direct route and kill the witnesses as opposed to merely bribing or intimidating them. Contrast Kangaroo Court, where everything about the case — including the witnesses and the jury — is deliberately geared toward convicting a defendant regardless of his/her innocence or guilt, and Joker Jury, where the jurors deliberately consist of the hero's enemies. For regular old jury service, see Jury Duty.

Note: witnesses perjuring themselves or backing out of testifying, or jurors initiating the swaying of their fellow jurors, for any reason other than previous outside provocation, is NOT this trope.

  • Diabolik: This happens with depressing regularity. In "The Witness", the mob boss Diego Parker has intimidated a witness and is about to walk away again when our titular Villain Protagonist walks in disguised as a witness against Parker in a previous trial for a robbery ended in a massacre, a witness dismissed because Parker's attempt to kill him before that trial had blinded him, declares he reacquired his sight and accuses him of that robbery. That was because Parker had decided to get the witness killed just in case... except that the guy had recently befriended Diabolik, who decided to take revenge for the (failed) attack on his friend.
  • L'Enquête Corse (The Corsican case): All jury members in a trial have received threatening letters from one side or the other. One of them claims he's still impartial because he received threats from both.
  • The Flash: One story features the ghost of a convicted murderer going after the jurors who convicted him. He turns out to be innocent and the real killer bribed the jury. The ghost is a juror who eventually came to regret the deal.
  • Judge Dredd: As revealed in the Origins story, this trope is what led to the Judge system being implemented; crime rates in the United States had spiraled completely out of control by the mid-2020s, culminating in an army of gang members led by the P Street Posse storming the White House, with the President just narrowly being rescued in time. Because of witness and jury intimidation, not a single conviction was made against the criminals. This was the last straw, and Congress passed an initiative created by Eustace Fargo that would get rid of due process entirely, and give law enforcement the authority to decide guilt and pass sentences themselves.
  • Rubine has a company on trial for poisoning a town kidnap the jury's children under the pretense of sending them to a vacation camp guarded by armed mercenaries. The title protagonist rescues the kids and bursts into the courtroom just as the forewoman is about to declare their verdict. The company is declared guilty, but the last panel shows they'd actually gone with "not guilty" out of fear for their kids.

  • In Blind Faith, Eddie, a defense attorney, privately interviews a witness who says she saw a black boy being chased through the park by a group of white boys. Her testimony is crucial to his argument that the defendant was acting in self-defense, but there's one problem: she says the boy was wearing a blue shirt, not a red shirt, which the defendant was wearing when he was arrested. During a break in the trial, Eddie tries to convince her to say the boy was wearing a red shirt, not a blue shirt. She's very hesitant about it, but she reluctantly goes along with it. It turns out she technically wasn't lying: those white boys were chasing two people, one in a red shirt, one in a blue shirt, who is revealed to be the defendant's gay lover.
  • The Juror: The mob boss Louie Boffano tries to sway Annie Laird, a juror in his trial, through his enforcer pretending to be her suitor.
  • The Phenix City Story: Implied. After the jury acquits the mobster Clem Wilson of the murder of Fred Gage by ruling the death accidental, John snarls that they're scared to death, to which Al replies that one can hardly blame them.
  • Runaway Jury: Rankin Fitch is a jury consultant who specializes in getting his clients their desired verdict through any means necessary, even resorting to blackmail and violence. It's eventually revealed that a third party is also attempting to influence the jury's decision through less devious means.
  • Suspect: Judge Helms correctly suspects that Kathleen and Eddie are illegally in contact, but can't prove it. They avoid being caught by him in the law library, but he sequesters the jury to prevent anything further, which forces Eddie to sneak out of the hotel. If this came out, they could be charged, and Kathleen might be disbarred or sanctioned. However, as Judge Helms is the murderer, no one's likely to really care that much, as they're small fry in comparison.
  • The Untouchables (1987): At the end, Al Capone bribes all the jurors in his tax-dodging trial to acquit him — Elliot Ness smells something fishy with the trial and asks the judge to switch the juries. He even puts some pressure on the judge, on a hunch that he's also been bribed, and the plan pays off, but only because of Artistic License – Law. A judge can't simply switch juries with another courtroom, as the new jury wouldn't know the facts of the case. The likeliest outcome would be a mistrial, and the judge may even be disrobed. In addition, Capone's attorney changes his client's plea to "guilty" without even consulting him, which is likely to get the lawyer disbarred and has no legal standing since the defendant would have to confirm the plea. Artistic License – Law indeed. In real life, what happened is that Judge Wilkerson switched the jury POOL last minute before Voir Dire (jury selection) had begun, because of suspicion some members of the pool had been bribed. This was legal because the trial itself hadn't started yet.

  • The Brass Verdict: One of the jurors is an impostor, paid by the accused to assume the identity of a juror in order to have at least one guaranteed Not Guilty vote.
  • Honor Harrington: In Field of Dishonor, three of the six officers serving as panel judges (the military equivalent of a jury) during Captain Pavel Young's Court Martial are either invested in his father's political faction or present in said father's voluminous blackmail files. This results in Admiral Hemphill offering a deal where Young is convicted of every charge that doesn't carry a death sentence, with the judges saying they were unable to reach a verdict on the others, resulting in Young being dishonorably discharged from the Navy but walking free to continue to cause trouble for the protagonists.
  • In Let Me Call You Sweetheart, mobster Jimmy Weeks has a history of bribing jurors to help get himself acquitted, such as paying one juror's medical bills for her sick relative. His lawyers, Anthony Bartlett and Bob Kinellen, are suspicious about this, but take the 'don't ask, don't tell' approach because he's their best client.
  • The No. 1 Ladies' Detective Agency: One book has Fanwell get framed for a crime and saddled with a phenomenally incompetent lawyer. Charlie gets the main witness (and the actual criminal) to rescind his evidence by doctoring a newspaper to present Mma Ramotswe as a Professional Killer who's in the courtroom to make sure Fanwell goes free. After it works, the unimpressed Mma Ramotswe has to spell out that it was a bad idea, even if done with the best of intentions.

  • The Runaway Jury has this as part of its main plot, to coerce or incapacitate the jurors in a lawsuit against tobacco companies for the plaintiff's husband's death from lung cancer (in The Film of the Book, it's a lawsuit against a gun manufacturer for gross negligence leading to the plaintiff's husband's death from an office shooting).

  • Better Call Saul: A variant in season 5. With Lalo Salamanca threatening to cause major problems for Gus Fring, Gus decides that Lalo needs to be locked up, so he has Mike lean on a witness to a murder that Lalo committed to indirectly get the police to link Lalo's car to the crime scene and thus arrest him.

    • "Working Girls": A Russian mob boss threatens the children of the man whose wife he's on trial for murdering in cold blood, scaring him into attempting to leave the city so that the guy's henchmen can gun him down. He tries a similar trick on a surviving witness after Danny and Jackie Curatola get her to court in one piece, except it doesn't work.
    • "Town Without Pity": Erin attempts to prosecute a doctor who went on the run after being accused of killing his wife. Her efforts are hindered by an attorney named Kathy Elliot, who hides his location in order to exclusively reveal his story on her podcast.

Elliot coughs up a piece of evidence making it seem like the murder victim is alive, but this is later disproved and she is forced to cooperate for the sake of her career.
  • Boardwalk Empire: Nucky Thompson sabotages his legal proceedings in the season 2 finale for election rigging through a variety of antics dropped at the very start of the trial, from one witness suddenly "committing suicide"note , another on the run for murder, and one suddenly getting married to the defendant.
  • Bones: A man who is about to testify against a big military contractor ends up with his wife dead and son kidnapped in order to keep him from testifying.
  • Castle has an example where this is done both ways by two people, to the same person, during the same trial. The first one (witness tampering) is the DA/prosecutor refusing to listen to testimony from a witness claiming that the defendant was innocent because, unbeknownst to the witness — actually the brother of someone involved in the accidental death of a rich girl — the DA was working to hide the victim's true cause of death (killed by her brother in an accident on a drug run). The second example (jury tampering) is the witness himself, desperate to keep an innocent man out of prison (he's a reformed convict, so he knows what it's like in prison), so he bought his way onto the jury in hopes of swinging the case for the defendant. This got the witness/juror murdered and became the episode's case.
  • Continuum: Julian is found not guilty at his trial for Roland's death because of witness perjury and jury tampering and a corrupt judge.
  • Daredevil (2015):
    • "Rabbit in a Snowstorm": James Wesley hires Nelson & Murdock to defend John Healy, an assassin arrested for bashing a gangster's head in with a bowling ball on the order of his boss, Wilson Fisk. Despite Foggy's reservations, Matt insists on taking the case, suspicious as to why an investment firm is paying the bill for a murder suspect's defense. Though he knows Healy is guilty as sin, Matt is committed to playing his part in a fair trial, so when he discovers that Fisk's men are coercing one of the jurors, he forces the thug who's blackmailing her to tell her to get herself excused. The jury hangs anyway, with strong implications that Fisk found other jurors to coerce, and more strings are pulled behind the scenes to get Healy off without a retrial. Matt hunts down Healy after he is released, gets him to admit that Fisk is his boss, and then promptly impales his head on a fence spike in fear of Fisk's retaliation.
    • Unintentionally happens during Frank Castle's trial in season 2 when Elektra, trying to help Matt out, intimidates the coroner who covered up the deaths of Frank's family into admitting the truth. His testimony gets thrown out due to having been made under duress, a wedge is driven between Matt and Foggy, and Matt is furious at Elektra for ruining his best chance at getting a mistrial for Frank.
    • Upon Wilson Fisk's release from prison in season 3, Matt, Karen, and Foggy each separately try different tactics to send him back to prison. After several attempts that fail or backfire with disastrous results, they finally get Ray Nadeem to testify before a grand jury about how Fisk blackmailed him and other FBI agents into being his glorified muscle in an extortion racket. Unfortunately, Fisk finds out from his connections what they're trying to do, and directs his street boss Felix Manning to ensure that he doesn't get indicted. He first attempts to have Nadeem killed by gunmen who ambush the police van escorting Nadeem (with Matt as his bodyguard) from Fogwell's Gym to the courthouse. Matt and Nadeem defeat Fisk's assassins and make it to the courthouse. Nadeem gives his testimony, but just as they think they're in the clear, a henchman sent by Fisk to the courtroom begins rattling off the names and addresses of the jurors, intimidating them into declining to indict Fisk. Nadeem, with nowhere to run, knocks Foggy out in the bathroom, returns home, films a dying confession (which is admissible evidence thanks to several loopholes), then resigns himself to his fate when Dex is sent to his house on Vanessa's orders to kill him.
  • The Good Wife: Kalinda threatens to get child services to take drug kingpin Lemond Bishop's son to force him to allow one of his dealers to testify to Cary's innocence in his drug trial.

He really was guilty, and later dumped the juror after being acquitted...and she was later forced to kill him in self-defense.
    • Law & Order: Special Victims Unit: In one episode, a couple sues their dead daughter's lesbian partner for custody of their granddaughter, saying that she's molesting her, and the little girl's testimony apparently confirms their suspicions. It turns out that they were convinced to sue, and that the girl was fed lines, by the homophobic prosecutor as part of his plot to "prove" that gay people are unfit to be parents.
  • Leverage: "The Juror #6 Job" becomes a battle behind the scenes over control of the outcome of a pharmaceutical lawsuit. To keep a Corrupt Corporate Executive from buying the jury, they decide to steal it instead.
  • The Listener: In one episode, the key witness in a mobster's murder trial is shot and seriously wounded. The cops think that the mobster could not intimidate the witness into not testifying and hired an assassin instead. However, they later discover that while there was indeed witness tampering, it was done by the prosecutor. The mobster was innocent of the murder and the witness was coerced into perjuring himself. The assassin was hired not to silence the witness, but to actually get him to tell the truth in court.
  • Matlock: Subverted in one episode. Defense attorney Ben Matlock interviews a potential witness and gets her story, then calls her to the witness stand to repeat it in front of the jury — where she tells a completely different story. Ben thinks that she's been tampered with, but according to her, this is the real story and she had been tampered with before when she had talked to him previously (and she wasn't under oath then).
  • The Mick: When Chip gets caught with naked pictures on his phone he must stand before the school's Honor Board, which his sister Sabrina is a member of.

  • Sherlock: Moriarty blackmails several jury members in a court case by hacking into their hotel television systems to threaten their families. He's so confident in this approach that he instructs his lawyer to offer no defense, which ought to result in an all-but-automatic guilty verdict, especially given that he was caught red-handed (all part of his plan). He's acquitted.
  • The Sopranos: Corrado Soprano Jr. persuades a juror not to deliver a guilty verdict against him by having his assistant Bobby threaten the safety of the juror's family.
  • Suits: Several examples show up.
    • In one episode, Harvey tells his Corrupt Corporate Executive client that there are witnesses who can link her to six murders. She insists that they bribe the witnesses to not testify. Harvey points out that this is legally, ethically, and strategically a bad idea, but she refuses to listen to him. In the end, they use Loophole Abuse to have the witnesses sue the corporation for civil damages, and thus any settlement money they are given cannot be legally considered a bribe.
    • In another episode, Harvey fears that the opposing lawyer in a sexual harassment trial will try to tamper with a key witness, but at the last minute, he realizes that the witness has been tampered with from the beginning. She is a fake and was never sexually harassed by the defendant, as she had told Harvey. The opposing lawyer hired her to tell Harvey a bunch of lies, and then on the stand, she would tell the truth, embarrass Harvey, and torpedo his case.
    • On yet another occasion, Harvey suspects that a prosecutor in a murder trial is tampering with witnesses and encouraging them to perjure themselves. He has good reason for his suspicions, as the prosecutor has a long history of tampering with witnesses and evidence. However, when Harvey confronts one of the witnesses, he realizes that the witness is actually telling the truth and (in a case of Poor Communication Kills) really thought that Harvey's client ordered the murders. When Harvey investigates the other witness, he discovers that the witness was tampered with, but the tampering was done by another lawyer in Harvey's firm who is trying to hide the fact that he is the one who ordered the murders.
  • Walker, Texas Ranger has had this happen all too often:
    • Season 5's "Texas vs. Cahill" had a mob boss killing his own defense attorney and framing Alex for it, but it was all Caught on Tape, thereby exonerating her.
    • Season 7's "Special Witness" had Trent being stabbed by a federally-wanted assassin (played by Gary Busey) so he couldn't testify against the mob boss who hired said assassin in court (his dislike for guns following an incident as a little boy proved to be his undoing this way), with the only witness to that attack being a Special Olympian he was escorting to running practice, to which the Rangers needed her help catching the assassin. Trent luckily pulls through in time to testify, because Walker arrested the assassin beforehand.
    • "Jacob's Ladder", also in Season 7, had a street gang known as the Firebloods threatening to burn down the houses of people in a neighborhood under their control after they witnessed one of their own kill a man who didn't want to join the gang so they don't testify against him after Walker and Trivette arrested him, and it soon escalates to wanting to kill a firefighter (played by John Schneider) that responded to the emergency, whose young son was grounded and ordered to do community service at the H.O.P.E. Center for spray-painting cars. Luckily, after Walker and Trivette capture all of the gang members, it's not long before all the residents of the entire neighborhood decide to testify and put all of them away for good. Likewise, the firefighter the gang tried to murder survived his injuries.
  • The Wire: In the pilot episode, drug lieutenant D'Angelo Barksdale is acquitted on a murder charge thanks to this. One witness is clearly scared by a number of men in suits (bosses or enforcers for the Barksdale drug gang, at the time the most powerful drug empire in Baltimore), giving him cold looks, but identifies D'Angelo as the man who shot another man during a fight. The second witness, on the other hand, surprises the prosecution when she contradicts what she told the police during the investigation, claiming that after she first spoke with the detective who investigated the case she "realized" she had a case of mistaken identity, and it wasn't actually D'Angelo but another man who did the shooting. Furthermore, she says that she tried but was unable to get ahold of the detective to tell him about this and point him to the "real killer". Due to the witnesses disagreeing D'Angelo is acquitted, and the furious judge demands an investigation of the group who engaged in witness tampering in his court, something which only becomes a bigger issue when the witness who did testify against D'Angelo turns up dead by the end of the episode. From that point forward in the series, both getting witnesses to cooperate against the drug gangs and protecting the lives of witnesses (or solving the murders of slain witnesses), becomes a serious recurring issue for the police and the justice system.

  • Ace Attorney:
    • Manfred von Karma is strongly implied to be involved in witness tampering as a means of keeping up his spotless conviction rate as a prosecutor. He also seems to have passed on his methods to his daughter and his student; they both have moments where their witnesses admit to having been told to not talk about somethingnote .
    • Apollo Justice: Ace Attorney: This is actually used by the good guys. As part of his plan to expose Kristoph Gavin as the one responsible for commissioning and delivering unto Phoenix the forged evidence (which he didn't know was forged when he presented it) that led to his attorney's badge being revoked, as well as the murder of Drew Misham and attempted murder of Vera Misham, Phoenix volunteers to be the one who selects jury members for a test run of the new "jurist system", which would allow regular citizens to ultimately decide the guilt or innocence of a defendant rather than the power resting solely with the judge. In the trial against Vera for the murder of her father, Apollo manages to expose Kristoph as the poisoner of both Mishams, but Kristoph points out that since the poisons had been sitting around in their home for seven years prior and he didn't directly force either of them to ingest any of it, no one can definitively prove him guilty for anything. It's then that we cut to the jury room when Vera's fate in the case is about to be decided, and we see an unnamed person asking Phoenix to clarify the rule about no jurors who have personal ties to the case at hand being allowed to vote. Phoenix agrees and states that the juror doesn't have any such personal tie to this case. It's then that we realize that the juror is Thalassa Gramarye, who we've known until recently as Lamiroir, who's regained her memory and learned that the man whom Kristoph was convicted for killing in the first case was her husband. Again, there's no irrefutable physical evidence to prove that Kristoph is guilty, but since Thalassa knows what kind of man he is, she votes Vera "not guilty", which allows her to go free and prompts Kristoph to burst into a legendary fit of unhinged laughter.
    • Phoenix Wright: Ace Attorney – Dual Destinies shows that exposing years of corruption in the legal system has devastated public trust, leading to prosecutors getting even more creative in their manipulations, specifically because they're already in The Tyson Zone.
    • The Great Ace Attorney: It's not the prosecutor who gets in on this, but rather the defendant, of all people! The third case has Magnus McGilded, who in the final case turns out to have threatened a seventeen-year-old girl into testifying in his favor and tampering with evidence of his crimes during the third trial.
  • Chrono Trigger: In one of the sidequests, Marle's father, the king of Guardia, is put on trial for selling the kingdom's royal treasure for petty cash. During the trial, the player gets to see that the prosecution's star witness was in fact setting up the king on orders from the chancellor. And then it turns out it wasn't the real chancellor, but a disguised descendant of Yakra, the very first boss the heroes defeated to save Marle's ancestor, Queen Leene.
  • Daughter for Dessert: Inverted. Detective Mortelli tampers with his own testimony (and the evidence) because he doesn’t want to see the protagonist go to jail over something that he firmly believes is right.
  • Grand Theft Auto:
  • Knights of the Old Republic: During one of the courtroom segments, it's possible for the player character to use Force Persuade to make witnesses perjure themselves. This is considered a Dark Side action.

  • Homestuck: During Terezi's mock trial in her introduction, Lemonsout tries to assassinate the prosecution's key witness by means of a large knife — and, given that this is "discovered" right as Terezi turns to call the witness to stand, this implicitly happened right in the court.

  • The Trial Of Tim Heidecker: One of the prosecution's witnesses is Mark Proksch, who testifies that Tim repeatedly abused him physically and emotionally as his boss. During cross-examination, Tim intimidates Mark into recanting his claims of abuse, but when the prosecution objects, Tim gets belligerent and starts directly threatening to assault people. He's dragged out by the bailiff and gets a contempt of court charge as a result.

    Western Animation 
  • Animaniacs: A Slappy the Squirrel short has Slappy accused of cartoon violence against Walter Wolf. Slappy's defense consists of describing how she basically blasted Walter to smithereens, leading the jury to find her...not guilty, at which point it's revealed that Slappy rigged explosives under the jury's seats.
  • Futurama: Used as a gag. At one trial against the robot mafia that Bender is testifying in, his lawyer claims jury tampering, which is followed by a shot of a mobster rewiring members of the (robot) jury.
  • Robot Chicken: The skit "Bop It... or Else" has a "Bop It" toy issuing a series of "[verb] it!" commands that end in turning into a sniper rifle and bullying a kid into assassinating a politician, being arrested by police before he can, when told, "End it!", and a trial arriving at the question of if the mastermind is present, with the still-talking toy insisting, "Zip it!"; this effort fails.
  • The Simpsons: This turns up often to showcase how corrupt Springfield is, through incredibly blatant bribing and threatening, sometimes right in the middle of the court's session. "The Boy Who Knew Too Much" is a notable subversion because, even with all of the bribery Mayor Quimby had done behind the scenes, his nephew Freddy was still going to go to jail if not for Bart's testimony (the fact that Freddy went into a raging tirade and threatened to kill everybody in court, jury included right in the middle of declaring under oath that he didn't have a Hair-Trigger Temper pretty much did it).
