Every dirty trick prosecutors and law enforcement use to secure convictions in California — and how to fight back
A Brady violation occurs when prosecutors hide or fail to disclose evidence that is favorable to the defendant. This includes anything that could prove innocence, impeach a prosecution witness, or reduce the sentence. It is one of the most common and devastating forms of prosecutorial misconduct. The prosecution has a constitutional obligation to turn over all favorable evidence — and they routinely break this rule.
This does not just mean evidence that proves you did not do it. It includes evidence that a witness lied, that a cop had a history of misconduct, that another suspect was investigated, or that forensic results were inconclusive. Prosecutors bury this material in massive file dumps, "forget" to disclose it, or claim it was not material. People go to prison for decades because of it.
John Hill spent decades in a California prison after prosecutors failed to disclose critical exculpatory evidence. The withheld material would have fundamentally changed the trial outcome. The court eventually found a Brady violation and ordered relief, but only after Hill lost most of his life behind bars.
A documented pattern of Brady violations emerged from the San Francisco District Attorney's office, where multiple cases revealed systematic failures to disclose favorable evidence to defendants. The pattern was so pervasive it pointed to an institutional culture of suppression rather than isolated mistakes.
In this case, the prosecution not only withheld favorable evidence but also presented false testimony, combining a Napue violation (knowingly using perjured testimony) with a Brady violation. The court found the prosecution suppressed evidence that would have impeached key witnesses.
Charge stacking is when prosecutors file every possible criminal charge arising from a single incident, even when many of those charges are duplicative or a stretch. A bar fight becomes assault, battery, assault with a deadly weapon, criminal threats, and disturbing the peace — all from one punch. The goal is not to win on every count. The goal is to make the total potential prison time so terrifying that the defendant gives up the right to trial and takes a plea deal.
This is how the system processes 95%+ of criminal cases without trials. Prosecutors overcharge massively, then "generously" offer to drop most counts if you plead guilty. It is a coercive system dressed up as negotiation. In California, where consecutive sentencing can multiply penalties, the threat of stacked charges can mean the difference between probation and decades in prison.
In a case that broke new ground, a property owner was hit with multiple criminal charges for removing squatters from his own property. Prosecutors stacked charges including assault and burglary for what the defense argued was a lawful property recovery. The case exemplifies how DAs use charge stacking to criminalize conduct that has never been prosecuted before.
A juvenile defendant received a 79-year sentence through aggressive charge stacking and consecutive sentencing. The case demonstrates how prosecutors can turn youthful offenses into virtual life-without-parole sentences by piling on every possible count and enhancement.
Kevin Epps was acquitted of the primary murder charge but still convicted on lesser stacked charges. Even when a jury rejects the prosecution's main theory, charge stacking ensures some conviction sticks. Epps faced severe punishment despite the jury finding him not guilty of the most serious allegation.
California has one of the most complex enhancement systems in the country. Enhancements are additional years added on top of the base sentence for things like gang affiliation, firearm use, prior strikes, or great bodily injury. Prosecutors abuse these by alleging gang enhancements based on flimsy evidence (wearing certain colors, living in a neighborhood, having friends who are gang members), stacking firearm enhancements on top of assault charges, and using prior convictions from decades ago as "strikes."
A simple assault that might carry 2-4 years can balloon to 25-to-life with a gang enhancement and a prior strike. This system disproportionately impacts Black and Latino communities in California. Prosecutors use enhancement allegations as leverage — they offer to drop the enhancement in exchange for a guilty plea to the base charge.
Enhancements turned what would have been a significant but survivable sentence into a virtual life sentence of 79 years for a juvenile offender. Stacked gang and firearm enhancements multiplied the punishment far beyond what the base crimes alone would have produced.
The California Racial Justice Act (AB 2542/AB 256) was enacted in part because of documented racial disparities in how gang enhancements are applied. Studies showed Black and Latino defendants were far more likely to face gang enhancements than white defendants committing similar crimes. The RJA allows defendants to challenge enhancements applied in a racially discriminatory manner.
The prosecution leveraged enhancement allegations to dramatically increase sentencing exposure, using the threat of enhanced penalties as leverage during plea negotiations. The case illustrates how enhancements function more as bargaining chips than as proportional justice.
Witness coercion happens when prosecutors or police pressure witnesses into giving testimony favorable to the prosecution. This can take many forms: threatening a witness with prosecution if they do not cooperate, offering deals on the witness's own pending charges in exchange for testimony, threatening to involve immigration authorities, or even threatening to take away someone's children through CPS. Detectives also use prolonged interrogation, isolation, and psychological pressure to shape witness statements before trial.
The coercion does not have to be dramatic. Simply telling a witness "we know you were there and if you don't tell us what happened, you'll be charged as an accessory" is enough to manufacture testimony. Witnesses who recant later are often threatened with perjury charges, trapping them in the prosecution's version of events.
The conviction was reversed due to prosecutorial misconduct involving witness handling. The court found that the prosecution's conduct in relation to witness testimony crossed the line from legitimate advocacy into misconduct that denied the defendant a fair trial.
In this death penalty case, the prosecution relied on witness testimony that was later shown to be false. Witnesses were given incentives to testify, and the prosecution failed to disclose the full extent of deals and pressure applied to obtain the testimony that sent defendants to death row.
Jamal Trulove was wrongfully convicted of murder in San Francisco after police pressured a witness into identifying him. The sole eyewitness later revealed she was coerced by officers who threatened her and coached her identification. Trulove was exonerated after 6 years in prison and later won a $13.1 million civil rights settlement.
Jailhouse informants — "snitches" — are incarcerated people who claim a defendant confessed to them in jail. In exchange for this testimony, informants receive reduced sentences, dropped charges, money, special privileges, or early release. The informant has every reason to lie and no reason to tell the truth. They study case details from court documents, news reports, or other inmates, then claim the defendant personally confessed.
California has been ground zero for jailhouse informant scandals. The Orange County Jail Informant Scandal revealed that prosecutors and sheriff's deputies ran a secret, systematic informant program for decades, placing informants near defendants and then denying the program existed. Innocent people went to prison — and to death row — based on fabricated snitch testimony.
This case involved a "Perkins operation" where undercover officers posed as inmates to elicit statements from the defendant. The court found the operation violated Miranda protections. These operations are essentially state-run informant schemes where officers themselves play the snitch role.
An informant's testimony was central to the wrongful conviction, with the snitch receiving significant benefits in exchange for claiming the defendant had confessed. Post-conviction investigation revealed the informant had a long history of providing false testimony in exchange for deals across multiple cases.
In this Orange County death penalty case, prosecutors used jailhouse informants as part of a pattern of misconduct. The case became part of the broader Orange County jailhouse informant scandal that revealed systematic use of placed informants, undisclosed deals, and fabricated testimony across hundreds of cases.
It seems impossible that an innocent person would confess to a crime they did not commit. But it happens constantly. Police use psychologically coercive interrogation techniques — the Reid Technique being the most infamous — that involve hours of isolation, lies about evidence ("your DNA was at the scene"), minimization ("just tell us what happened and you can go home"), and threats ("if you don't cooperate, you'll get life"). Juveniles, people with intellectual disabilities, and those with mental illness are especially vulnerable.
False confessions are present in approximately 29% of DNA exoneration cases nationwide. Once a confession exists, it is almost impossible to overcome at trial — juries simply cannot believe someone would confess to something they did not do. The confession becomes the case, even when physical evidence points elsewhere.
14-year-old Michael Crowe was subjected to hours of psychologically coercive interrogation by Escondido police after his sister Stephanie was murdered in 1998. Detectives used the Reid Technique, told Crowe his hair was found in the victim's hand (a lie), and broke him down until he confessed. DNA evidence later proved a transient committed the murder. Crowe and his family won a civil rights lawsuit against the police.
The Crowe family's civil suit exposed the full extent of the coercive interrogation tactics used on a 14-year-old who was told he failed a lie detector test (a lie), that his hair was at the scene (also a lie), and that things would "go easier" if he just explained what happened. The case became a national example of how police can manufacture confessions from innocent children.
A wrongful conviction driven in part by a coerced or unreliable confession. The case demonstrates how once a confession enters the record — regardless of the circumstances under which it was obtained — it dominates the entire proceeding and makes acquittal nearly impossible.
Eyewitness misidentification is the single leading cause of wrongful convictions in the United States, contributing to approximately 69% of DNA exonerations. Human memory is not a video camera. It is reconstructive, malleable, and deeply influenced by suggestion. Police exploit this by conducting suggestive lineup procedures: showing the witness a photo array where the suspect's photo stands out, telling the witness "we think one of these people did it," giving confirming feedback after the witness picks someone ("good, you got him"), or conducting show-ups where a single suspect is presented.
Cross-racial identification is particularly unreliable — decades of research shows people are significantly worse at identifying faces of other races. Yet California courts routinely admit cross-racial identifications without expert testimony explaining this well-documented phenomenon. Once a witness makes an identification, their confidence becomes cemented through repetition and confirmation, even when the original identification was uncertain.
Maurice Hastings spent 38 years in prison for a murder he did not commit in Los Angeles. Eyewitness identification played a role in his conviction. DNA testing — which the prosecution resisted for decades — finally proved his innocence in 2022, making his one of the longest wrongful imprisonments in California history.
Trulove's wrongful murder conviction in San Francisco was built on a single eyewitness who was pressured by police into making the identification. The witness later revealed the identification was coerced. Trulove served 6 years before exoneration and won $13.1 million in his civil rights lawsuit.
Eyewitness misidentification contributed to a wrongful conviction that cost the state $12 million in settlement payments. The case highlighted failures in identification procedures and the devastating consequences of relying on unreliable eyewitness testimony without scientific safeguards.
For decades, prosecutors presented forensic "science" as infallible. Bite mark analysis. Hair comparison. Shaken baby syndrome. Arson indicators. Blood spatter interpretation. Bullet lead analysis. Much of this was never validated by rigorous science. A landmark 2009 National Academy of Sciences report found that most forensic disciplines — except DNA — lacked scientific foundation. People went to prison and death row based on an "expert" saying a bite mark matched or that a hair was "consistent with" the defendant's.
Beyond junk science, California has been plagued by crime lab scandals where technicians contaminated samples, fabricated results, or failed to follow protocols. When the lab is run by the same agency prosecuting the case, the incentive to produce prosecution-friendly results is baked into the system.
Regi Tanubagijo was convicted based on "shaken baby syndrome" diagnosis — a theory that has been increasingly discredited by the medical community. The symptoms attributed to shaking can have multiple natural causes. Tanubagijo's case represents one of many California convictions built on forensic science that the scientific community has moved away from.
In this extraordinary case, the federal government itself was caught committing fraud with forensic evidence. A federal judge found that government investigators fabricated and manipulated evidence in an arson case against Sierra Pacific Industries. The court imposed sanctions and a federal prosecutor was referred for discipline.
Wrongful murder convictions driven in part by questionable forensic evidence. The case demonstrates how prosecutors present forensic conclusions with far more certainty than the underlying science supports, and how defense attorneys are often unable to effectively challenge forensic evidence due to resource disparities.
Selective prosecution occurs when a DA singles out one person for prosecution while others who engaged in the same or similar conduct go uncharged. This becomes unconstitutional when the selection is based on race, religion, political activity, exercise of constitutional rights, or other impermissible factors. It is one of the hardest forms of misconduct to prove because defendants must show both discriminatory effect (similarly situated people were not prosecuted) and discriminatory intent (the DA had an impermissible motive).
In practice, DAs have nearly unchecked discretion to decide who gets charged. This discretion is wielded disproportionately against people of color, political dissidents, people who file complaints against police, and anyone the DA's office perceives as a problem. The California Racial Justice Act now provides a pathway to challenge racially selective prosecution.
James Jacobs was the first person in California history prosecuted for removing squatters from his own property. Despite widespread squatter removal activity by property owners across the state, only Jacobs was charged. The selective nature of this prosecution — targeting one individual for conduct that is universally practiced — raises fundamental questions about prosecutorial motives.
Former NFL player Dana Stubblefield's conviction was overturned using the California Racial Justice Act, with evidence showing racial bias influenced the prosecution's decisions. The case was one of the first successful RJA challenges and demonstrated that selective prosecution based on race can now be effectively challenged in California courts.
The full implementation of the California Racial Justice Act has begun revealing patterns of selective prosecution across multiple counties. Statistical analyses are showing significant racial disparities in who gets charged, what charges are filed, and what enhancements are alleged, creating the first data-driven framework for challenging selective prosecution in California.
Vindictive prosecution occurs when a prosecutor increases charges, adds enhancements, or takes harsher action against a defendant specifically because the defendant exercised a legal right — such as rejecting a plea deal, requesting a jury trial, filing a complaint, or appealing a conviction. It is the government punishing you for making them do their job.
Classic examples: you reject a plea offer and suddenly face new, more serious charges. You win an appeal and get retried, but now the DA files additional counts they did not charge the first time. You file a complaint against a police officer and suddenly get arrested for something that happened months ago. The message is clear: do not fight us, or we will make it worse.
The timeline of the Jacobs prosecution raises vindictive prosecution concerns, with the escalation of charges corresponding to the defendant's exercise of legal rights and public advocacy. When a prosecution intensifies in direct response to a defendant fighting back, it creates a pattern consistent with vindictive prosecution.
After a defendant sought resentencing under juvenile justice reforms, the DA took aggressive action to strip the resentencing opportunity. The case illustrates how prosecutors retaliate against defendants who exercise their rights to seek relief under new laws, treating the exercise of statutory rights as an affront to be punished.
While a civil case, Pechkis demonstrates the broader pattern of government retaliation against individuals who exercise their rights. When institutions punish people for speaking up or pursuing legal remedies, it chills the exercise of constitutional rights across the system.
Pretrial publicity misconduct occurs when prosecutors use the media to poison the jury pool before trial. DAs hold press conferences announcing charges with inflammatory language, release mugshots and details designed to make the defendant look guilty, leak evidence to reporters, and characterize defendants in ways that would never be allowed in court. Because most potential jurors consume local news, this effectively puts the prosecution's narrative in front of the jury before the defense has said a single word.
Elected DAs are especially prone to this because high-profile prosecutions generate media coverage that helps them get re-elected. They frame themselves as tough-on-crime heroes in press conferences where the defendant is not present and has no opportunity to respond. By the time trial arrives, every potential juror has already heard the DA's version of events presented as established fact.
The prosecution of James Jacobs was accompanied by significant media coverage driven in part by DA statements characterizing the case in prejudicial terms before trial. When prosecutors use the media to build their case in the court of public opinion, they effectively deny defendants the presumption of innocence.
A false murder prosecution that included public statements by law enforcement and prosecutors that prejudiced the case before it reached a courtroom. When Moore was ultimately vindicated, the damage from pretrial publicity had already been done to his reputation and life.
The misconduct in Mirabal extended beyond the courtroom, with the prosecution's conduct throughout the case contributing to an atmosphere that denied the defendant fair treatment. The appellate court reversed the conviction after finding pervasive prosecutorial misconduct.
Prosecutors systematically remove Black, Latino, and other jurors of color from juries using peremptory challenges — strikes that do not require a stated reason. Although the Supreme Court ruled in Batson v. Kentucky (1986) that race-based strikes are unconstitutional, prosecutors have perfected the art of providing pretextual "race-neutral" reasons: "She seemed inattentive," "He lives in a high-crime area," "She had a family member in the criminal justice system." These reasons are almost always accepted by judges.
The result is that in California, Black and Latino defendants are routinely tried by disproportionately white juries, even in diverse communities. Studies have shown that prosecutors strike Black jurors at 2-3 times the rate of white jurors. California's Racial Justice Act (AB 2542) and the Jury Selection Reform Act (AB 3070) were enacted specifically to combat this practice.
In People v. Alston, the court found that the prosecution engaged in discriminatory jury selection by using peremptory challenges to remove jurors of color. The case demonstrated the pattern of using facially neutral but pretextual reasons to exclude minority jurors and helped establish the evidentiary framework for challenging such practices in California.
People v. Aguilar addressed the standards for proving discriminatory jury selection in California courts. The case established important precedent about what evidence is sufficient to raise a Batson challenge and how courts should evaluate the prosecution's stated reasons for strikes against jurors of color.
One of the cases testing the California Racial Justice Act, In re Lynex involved a challenge to the conviction based on racial bias in jury selection. The case is helping to define how the RJA's provisions on jury discrimination will be applied in practice, setting standards that will affect thousands of future cases.
When police use excessive force — particularly deadly force — a cover-up system activates. Officers coordinate their stories before filing reports. Body camera footage "malfunctions" or is withheld. The DA's office, which depends on police cooperation to prosecute cases every day, investigates the incident and almost always clears the officer. Victims who survive are often charged with resisting arrest or assault on an officer to create a counter-narrative and discourage civil lawsuits.
In California, despite reforms like SB 1421 (opening police misconduct records) and AB 392 (tightening use-of-force standards), the fundamental conflict of interest remains: the DA who must decide whether to charge the officer is the same DA who works with that officer every day. Officers know the system protects them, which emboldens misconduct.
LA County Sheriff's deputies shot and paralyzed Isaias Cervantes, a deaf autistic man, in his own neighborhood. Despite the shocking facts, the DA's office took no action against the officers. The case represents the standard pattern: excessive force against a vulnerable person, no criminal accountability, and a civil lawsuit as the only path to any justice.
Anthony Lowe, a double amputee in a wheelchair, was shot and killed by Huntington Park Police officers. The circumstances of the shooting raised immediate questions about the necessity of deadly force against a man with no legs. The case drew national attention to the pattern of California police using lethal force against disabled individuals with impunity.
Keenan Anderson, a 31-year-old teacher and cousin of Black Lives Matter co-founder Patrisse Cullors, died after LAPD officers repeatedly tased him during a traffic stop. His death was caught on body camera, showing officers using prolonged taser deployment. The case illustrates how force that falls short of a firearm can still be lethal, and how the system protects officers even when video evidence contradicts their account.
Discovery abuse is the everyday cousin of Brady violations. While a Brady violation involves hiding clearly exculpatory evidence, discovery abuse encompasses a broader range of obstructive tactics: disclosing evidence at the last minute so the defense cannot prepare, burying important documents in thousands of pages of irrelevant material, providing incomplete police reports with key pages missing, claiming certain materials are "privileged" or "work product," and simply failing to respond to discovery requests until forced by a court order.
The practical effect is devastating. Public defenders with hundreds of cases cannot review a 10,000-page document dump received the night before trial. Private defense attorneys burn through their clients' funds just trying to get documents they are legally entitled to. Meanwhile, the prosecution has had all the evidence for months or years. It is a rigged system where the prosecution controls the information and parcels it out strategically.
The pattern of Brady violations documented in the San Francisco DA's office included systematic discovery failures where evidence was not disclosed in a timely manner, critical documents were omitted from discovery packages, and the defense was left in the dark about key evidence until it was too late to effectively use it.
The Nuno case established that Brady disclosure obligations extend to resentencing proceedings, not just original trials. Prosecutors had argued they had no obligation to disclose favorable evidence during resentencing hearings, effectively trying to limit defendants' discovery rights at the very proceeding designed to correct injustice.
The Hill case represents discovery abuse at its most extreme: exculpatory evidence that should have been disclosed before trial was not revealed for decades. The defendant spent most of his life in prison while prosecutors sat on evidence that would have changed the outcome. Late disclosure, when it involves exculpatory material, is not just a procedural violation — it is a human rights abuse.
Plea deal coercion is the engine that drives the American criminal justice system. Over 95% of criminal convictions in California come from plea bargains, not trials. The system works like this: prosecutors stack charges to create maximum sentencing exposure (see Tactic 2), then offer a "generous" plea deal that reduces the charges. The message is explicit — plead guilty and get 3 years, or go to trial and risk 25-to-life. Innocent people take plea deals every day because the risk of trial is too catastrophic to bear.
The coercion is multiplied when defendants are held in pretrial detention and cannot make bail. They face losing their jobs, homes, and custody of children while waiting months or years for trial. Taking a plea — even to a crime they did not commit — gets them out immediately. The system is designed to make the rational choice for innocent people be: plead guilty and go home, rather than fight and risk losing everything. The National Registry of Exonerations has documented hundreds of false guilty pleas.
The collapse of the public defender system directly feeds plea coercion. When public defenders carry caseloads of 400-600 cases, they cannot investigate, prepare for trial, or provide meaningful counsel. The only way to manage impossible caseloads is to push clients toward plea deals. Defendants represented by overwhelmed public defenders are essentially being processed, not defended.
Defendants were not properly advised about the immigration consequences of guilty pleas, making their pleas involuntary. For non-citizen defendants, a guilty plea can mean deportation, permanent inadmissibility, and separation from family. When these consequences are not disclosed, the plea cannot be considered knowing and voluntary.
Public defenders in Solano County went on strike over impossible caseloads that prevented them from providing adequate representation. The strike exposed how the system depends on defenders processing guilty pleas rather than advocating for their clients. When defenders cannot investigate or prepare for trial, plea coercion becomes the default outcome for every case.
If you or someone you know has been subjected to any of these tactics, you are not alone. Document everything, demand your rights, and hold the system accountable.
