One of our editors wanted to know how the American criminal justice system actually resolves cases. The answer is simpler and more unsettling than most people expect: plea bargainingAn agreement between a prosecutor and defendant where the defendant pleads guilty—usually to a lesser charge or in exchange for a lighter sentence—rather than going to trial. has replaced trials almost entirely.
Plea bargaining accounts for nearly 98 percent of criminal convictions in the United States, according to a 2023 American Bar Association task force report. In the federal system specifically, only 2 to 3 percent of convictions result from trials. The courtroom drama that dominates American television, film, and public imagination is, statistically, almost entirely fictional.
The system that replaced it receives remarkably little public scrutiny for something that determines the freedom of millions of people every year.
How Plea Bargaining Works
A plea bargain is an agreement between a prosecutor and a defendant in which the defendant pleads guilty, usually to a lesser charge or in exchange for a lighter sentence recommendation, rather than going to trial. The practice takes two primary forms: charge bargainingA form of plea negotiation where the prosecutor agrees to drop or reduce charges in exchange for a guilty plea., where the prosecutor drops or reduces charges, and sentence bargainingA form of plea negotiation where the prosecutor recommends a specific sentence to the judge in exchange for a guilty plea., where the prosecutor recommends a specific sentence to the judge.
The process typically unfolds in private. There is no jury, no cross-examination, no public presentation of evidence. A defendant meets with their attorney, reviews the offer, and decides whether to accept. If they do, a judge confirms the plea in a brief hearing and enters a conviction. The entire process can take minutes.
This is not new. Plea bargaining has been a feature of American criminal law since at least the mid-nineteenth century. But its dominance is relatively recent. In the 1970s, roughly 20 percent of federal cases went to trial. By 2022, that figure had fallen below 3 percent.
The Structural Power Imbalance
The central tension in plea bargaining is that the two parties negotiating are not equal. Prosecutors hold almost every structural advantage.
Prosecutors decide what charges to file. In most jurisdictions, they can stack multiple charges for a single alleged act, each carrying its own potential sentence. They control the timing of the case. They have access to investigative resources that most defense attorneys, particularly public defenders handling hundreds of cases simultaneously, cannot match.
Most critically, prosecutors control the gap between what they offer in a plea deal and what a defendant faces if convicted at trial. This gap has a name.
The Trial PenaltyThe difference between the sentence offered in a plea bargain and the sentence imposed after a trial conviction. Defendants choosing trial risk dramatically harsher punishment.
The trial penalty is the difference between the sentence offered in a plea bargain and the sentence imposed after a trial conviction. At the federal level, trial sentences are roughly three times higher than plea sentences for the same offense, according to the National Association of Criminal Defense Lawyers. In some cases, the disparity reaches eight to ten times higher.
The Supreme Court has ruled this is constitutional. In Bordenkircher v. Hayes (1978), a Kentucky prosecutor offered Paul Lewis Hayes a five-year sentence for forging an $88.30 check. When Hayes refused the deal, the prosecutor filed additional charges under Kentucky’s habitual criminal statuteA law that imposes significantly enhanced penalties when a defendant has been convicted of multiple felonies, allowing prosecutors to leverage prior convictions to pressure guilty pleas.. Hayes was convicted and sentenced to life in prison. The Supreme Court upheld the sentence, ruling that the threat of more severe charges is a legitimate part of plea negotiations as long as the defendant is “free to accept or reject” the offer.
The word “free” is doing considerable work in that sentence. A defendant choosing between five years and life imprisonment is technically free to reject the offer. Whether that choice is meaningfully voluntary is a different question.
How Innocent People Plead Guilty
The trial penalty creates a specific problem: it gives innocent defendants a rational reason to plead guilty.
Consider a defendant who is factually innocent but faces serious charges. Their attorney explains the evidence, the risks, and the math. A plea deal offers two years. A trial conviction could mean twenty. Even if the defendant believes they would likely be acquitted, “likely” is not “certainly.” The rational calculation, for many people, points toward accepting the deal.
This is not hypothetical. The National Registry of Exonerations has documented hundreds of cases where exonerees pleaded guilty to crimes they did not commit. In drug cases, the proportion is far higher: nearly all drug-crime exonerations in the registry involved guilty pleas, often in cases where laboratory testing later confirmed the seized substances were not illegal drugs.
The case of Kalief Browder illustrates what happens to those who refuse. In 2010, Browder, then sixteen years old, was arrested in the Bronx for allegedly stealing a backpack. Unable to post $3,000 bail, he was sent to Rikers Island. He was offered plea deals repeatedly and refused them all, insisting on his innocence. He spent three years in jail awaiting trial, including roughly 700 days in solitary confinement. In 2013, prosecutors dismissed the charges after their sole witness left the country. Two years after his release, Browder died by suicide. He was twenty-two.
Browder’s case is extreme. But its logic is not unusual. The system is designed so that refusing a plea bargain, even when innocent, carries enormous personal cost.
What the Supreme Court Has and Has Not Said
The Supreme Court has acknowledged the dominance of plea bargaining without meaningfully constraining it. In Missouri v. Frye (2012), Justice Anthony Kennedy wrote that the American criminal justice system “is for the most part a system of pleas, not a system of trials.” He cited statistics showing that 97 percent of federal convictions and 94 percent of state convictions resulted from guilty pleas.
Frye and its companion case, Lafler v. Cooper (2012), established that the Sixth Amendment right to effective counsel extends to the plea bargaining process. If a lawyer’s incompetent advice causes a defendant to reject a favorable plea deal, that constitutes a constitutional violation.
What the Court has not done is address the structural coercion built into the system itself. The trial penalty, charge stacking, and the power imbalance between prosecutors and defendants remain constitutionally permissible. The Court has treated plea bargaining as a voluntary transaction between consenting parties, even when one party controls the terms, the timeline, and the consequences of refusal.
The Transparency Problem
Trials are public proceedings. Plea bargains are not. This creates an accountability gap that the ABA’s 2023 task force report described as a threat to the integrity of the justice system itself.
When a case goes to trial, evidence is presented, witnesses are cross-examined, police conduct is scrutinized, and the outcome is recorded in detail. When a case resolves through a plea, none of that happens. Prosecutorial misconduct, police errors, and flawed evidence can pass through the system unchallenged because the adversarial process that would have exposed them never occurs.
The ABA task force found that Black defendants are less likely to receive favorable plea offers and less likely to see charges dropped entirely. More than 60 percent of exonerees who had pleaded guilty are people of color, according to the Innocence Project. Because plea negotiations happen in private, these disparities are difficult to measure systematically and even harder to challenge.
Why the System Persists
The honest answer is capacity. American courts do not have the resources to try every case. If even a modest fraction of defendants currently accepting plea deals demanded trials instead, the system would collapse. Plea bargaining is not a feature of the justice system; in functional terms, it is the justice system.
This creates a self-reinforcing dynamic. Because plea bargaining handles nearly all cases, courts are staffed and funded for that volume. Because courts are staffed and funded for that volume, they cannot absorb a significant increase in trials. Because they cannot absorb more trials, prosecutors have even more leverage to pressure defendants into plea deals.
The ABA task force proposed fourteen principles for reform, including eliminating the use of pretrial detention to coerce guilty pleas and prohibiting defendants from being required to waive their right to appeal. The recommendations were adopted as ABA policy in August 2023. Whether any jurisdiction implements them is a separate question.
The Gap Between Perception and Reality
American popular culture presents a criminal justice system built on trials. Twelve jurors deliberate. Attorneys deliver closing arguments. Justice, in one direction or another, is rendered through an adversarial process designed to test evidence and protect rights.
The actual system works differently. A prosecutor makes an offer. A defense attorney, often overworked and underfunded, advises their client on the odds. The client accepts or faces consequences that are, by design, dramatically worse. A judge confirms the result. The process is fast, efficient, and almost entirely invisible to the public.
Whether that system produces justice is a question the system itself is not designed to answer. Plea bargaining resolves cases. It clears dockets. It keeps an underfunded apparatus functioning. What it does not do, and has never claimed to do, is determine the truth.
