Discrimination in the criminal justice system refers to the unequal treatment people receive based on race, ethnicity, or wealth as they move through policing, prosecution, trial, sentencing, and life after a conviction. The Fourteenth Amendment promises every person “equal protection of the laws,” but research shows that outcomes diverge sharply at every stage, and the legal doctrines meant to police those disparities set a high bar for proving them.1Congress.gov. U.S. Constitution – Fourteenth Amendment This article walks through where bias enters the system, what the numbers look like, and what a person can actually do about it.
Where It Starts: Stops, Searches, and Discretion
Most people’s first contact with the system is a police officer, and the governing legal standards give officers wide latitude. Under Terry v. Ohio (1968), an officer who “reasonably suspects” criminal activity can stop and pat someone down for weapons without probable cause for an arrest.2Justia U.S. Supreme Court Center. Terry v. Ohio, 392 U.S. 1 (1968) Reasonable suspicion is a subjective bar, and critics argue it leaves room for stops driven by racial stereotypes rather than evidence.
Traffic stops work the same way. In Whren v. United States (1996), the Supreme Court unanimously held that a stop is constitutional as long as the officer has probable cause for any traffic violation, regardless of the officer’s actual motive.3Justia U.S. Supreme Court Center. Whren v. United States, 517 U.S. 806 (1996) Because almost every driver eventually commits a minor infraction, the ruling effectively lets officers choose whom to pull over. Studies consistently show drivers of color are stopped, searched, and ticketed at higher rates even after accounting for driving behavior.
Stop-and-frisk programs have drawn the sharpest judicial pushback. In Floyd v. City of New York (2013), a federal court found that the city’s program violated the Fourth and Fourteenth Amendments and amounted to “a policy of indirect racial profiling by targeting racially defined groups” for stops.4Justia Law. Floyd v. City of New York, No. 13-3088 (2d Cir. 2014) The underlying national framework that permits brief suspicion-based stops is still intact.
Bail and Pretrial Jail
After arrest, bail decides whether a defendant waits for trial at home or in a cell. One study found that Black defendants are about 3.6 percentage points more likely than white defendants to be assigned cash bail, and when bail is set, the amounts average nearly $10,000 higher. These gaps hold up even after controlling for similar charges.5National Center for Biotechnology Information. Examining Racial and Ethnic Disparity in Prosecutors Bail Requests and Downstream Decision-making
The downstream effects compound. People who cannot post bail lose jobs, housing, and sometimes custody while they sit in jail. They also face enormous pressure to accept plea deals as the fastest route out, and research shows pretrial detention correlates with harsher sentences for identical charges. Because wealth is unevenly distributed by race, a bail system that punishes poverty amplifies racial disparities in everything that follows.
Reform has been uneven. Illinois became the first state to fully abolish cash bail in 2023, and Washington D.C., New Jersey, and New Mexico have scaled back its use. Other states have moved the opposite direction and expanded the offenses that require cash bail.
Prosecutors and Plea Deals
Prosecutors decide whether to file charges, which charges to bring, and what plea deals to offer, and that discretion is largely insulated from review. In United States v. Armstrong (1996), the Supreme Court required a defendant alleging selective prosecution based on race to first show that similarly situated people of other races were not prosecuted. The Court acknowledged that burden is extraordinarily hard to meet.
Because over 95 percent of criminal cases end in plea bargains rather than trials, these charging choices effectively set sentences for nearly everyone in the system. Two people arrested for the same conduct can face very different charges depending on who handles the file, and the race of the victim can shift aggressiveness as well, with cases involving white victims drawing harsher prosecution in violent crime.
The Quality of Your Defense Depends on What You Can Pay
Since Gideon v. Wainwright (1963), the government must provide a lawyer to defendants who cannot afford one. The quality of that representation varies enormously. Public defender offices are chronically underfunded, and when a single lawyer carries hundreds of open cases, investigation, motion practice, and trial preparation suffer.
Challenging bad representation after the fact is nearly as hard. Under Strickland v. Washington (1984), a defendant must prove both that the lawyer’s performance was objectively unreasonable and that the errors likely changed the outcome.6Justia U.S. Supreme Court Center. Strickland v. Washington, 466 U.S. 668 (1984) Courts rarely second-guess trial strategy, so even plainly overworked attorneys usually clear the constitutional floor. Wealthy defendants hire private counsel; indigent defendants, who are disproportionately people of color, get whatever their overburdened public defender can manage.
Jury Selection
Each side in a criminal case can use peremptory challenges to remove potential jurors without stating a reason. Federal rules allow between 3 and 20 strikes per side depending on the severity of the charge.7Legal Information Institute. Federal Rules of Criminal Procedure Rule 24 – Trial Jurors Batson v. Kentucky (1986) bars prosecutors from striking jurors solely because of race, and defendants can raise a Batson challenge when they suspect it.8Justia U.S. Supreme Court Center. Batson v. Kentucky, 476 U.S. 79 (1986)
In practice, these challenges rarely succeed. Prosecutors can offer almost any race-neutral reason, from a juror seeming disinterested to living in a particular neighborhood, and trial judges routinely accept those explanations. Several states have begun shifting the test from intent to impact, asking whether a strike disproportionately removes jurors of a particular race regardless of the stated justification.
Sentencing
Even after conviction for comparable crimes, sentences diverge by race. The U.S. Sentencing Commission has found that Black men receive federal prison sentences about 4.7 percent longer than white men convicted of comparable offenses, and the gap grows when the analysis includes cases where probation rather than prison was imposed.9United States Sentencing Commission. November 14, 2023 Press Release
Crack Versus Powder Cocaine
The clearest example of a racially skewed sentencing rule is the treatment of crack versus powder cocaine. The Anti-Drug Abuse Act of 1986 set a 100-to-1 ratio: 5 grams of crack triggered the same five-year mandatory minimum as 500 grams of powder. Crack was more prevalent in Black communities while powder was associated with wealthier, mostly white users, so the policy sent Black defendants to prison for far longer terms for the same drug.
The Fair Sentencing Act of 2010 raised the five-year threshold from 5 grams to 28 grams of crack, cutting the ratio to roughly 18-to-1.10Congress.gov. Cocaine – Crack and Powder Sentencing Disparities The First Step Act of 2018 made those changes retroactive, letting people sentenced under the old ratio petition for reductions.11United States Sentencing Commission. First Step Act of 2018 Resentencing Provisions Retroactivity Data Current federal thresholds reflect those amendments: 28 grams of crack or 500 grams of powder for the five-year minimum, and 280 grams of crack or 5 kilograms of powder for the ten-year minimum.12Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts Bills to eliminate the remaining 18-to-1 gap have been introduced in Congress but have not passed as of 2026.
Mandatory Minimums
Mandatory minimums force judges to impose a fixed prison term regardless of the defendant’s role or history, which effectively transfers sentencing power from the judge to the prosecutor who chose the charge.13Federal Judicial Center. The Consequences of Mandatory Minimum Prison Terms Among those convicted of federal mandatory-minimum offenses, 38.1 percent are Hispanic, 29.5 percent are Black, and 28.5 percent are White.14United States Sentencing Commission. Mandatory Minimum Penalties
Why Statistics Alone Won’t Win a Case
In McCleskey v. Kemp (1987), the Supreme Court reviewed a study showing that Georgia defendants were far more likely to receive the death penalty when the victim was white. The Court accepted the statistical disparity but held it insufficient. A defendant must prove intentional discrimination in his own case, not just a pattern across the system.15Justia U.S. Supreme Court Center. McCleskey v. Kemp, 481 U.S. 279 (1987) That ruling closed the door on systemic challenges based on aggregate data and left defendants to fight bias one case at a time.
The Juvenile System
The juvenile system was built around rehabilitation, but racial disparities begin early. Zero-tolerance school discipline sends students into the justice system for conduct that once drew a visit to the principal, and students of color are disciplined and referred to law enforcement at rates well above their share of enrollment.
Inside the juvenile system, one of the most consequential decisions is whether to transfer a young person to adult court. Forty-six states give juvenile court judges discretion to waive jurisdiction and send minors into the adult system, where they face longer sentences, adult records, and incarceration with adults.16Office of Juvenile Justice and Delinquency Prevention. Trying Juveniles as Adults in Criminal Court – An Analysis of State Transfer Provisions Research indicates that minority youth are more likely to be transferred than white youth charged with similar conduct, and an adult conviction carries lifetime collateral penalties that make reentry far harder.
Life After Conviction
A conviction follows people out of prison through a web of restrictions on voting, housing, and work, and because convictions fall unevenly by race, these collateral consequences deepen existing inequalities.
Felony disenfranchisement bars an estimated 4.4 million Americans from voting, about 2 percent of the voting-age population. Roughly one in 19 Black adults is disenfranchised, a rate 3.5 times that of non-Black Americans. Rules vary by state, from automatic restoration on release to permanent bans absent gubernatorial clemency.
Federal law lets public housing authorities deny admission based on criminal history, and private landlords routinely screen for convictions. Audit studies have found landlords apply stricter screening and sometimes higher fees to Black applicants with the same record as white applicants. Employment follows the same pattern: a criminal record cuts callback rates for everyone, but the penalty for Black applicants with a record is roughly double that for white applicants with comparable histories. Many states also restrict professional licensing for people with felony convictions, closing off whole industries regardless of rehabilitation.
What You Can Actually Do
Several legal avenues exist for people who believe their rights were violated, each with real limits.
Sue Under Section 1983
42 U.S.C. ยง 1983 lets anyone whose constitutional rights were violated by someone acting under government authority sue for damages.17Office of the Law Revision Counsel. 42 USC 1983 – Civil Action for Deprivation of Rights Qualified immunity blocks most of these claims. An officer cannot be sued unless the conduct violated a right that was “clearly established” by prior cases with nearly identical facts, which shields even plainly unconstitutional behavior when there is no close precedent.
Suing a city or county is possible but narrow. Under the Monell standard, a municipality is liable only when an official policy or custom caused the violation. A single incident is usually not enough; the plaintiff has to show the municipality was deliberately indifferent to a known pattern.18U.S. Commission on Civil Rights. Revisiting Who Is Guarding the Guardians
File a Civil Rights Complaint
Individuals who believe their civil rights were violated by law enforcement can report the incident to the Department of Justice’s Civil Rights Division through its online portal. The Division handles complaints about police brutality, racial profiling, and denial of rights during arrest or incarceration.19U.S. Department of Justice, Civil Rights Division. Contact the Civil Rights Division For incidents involving potential criminal misconduct by officers, the DOJ directs complainants to the FBI. Filing does not guarantee an investigation, but aggregate complaint data can help build the record for a broader federal inquiry.
DOJ Pattern-or-Practice Investigations
Federal law authorizes the Attorney General to investigate law enforcement agencies suspected of a pattern of unconstitutional conduct.20Office of the Law Revision Counsel. 34 USC 12601 – Cause of Action When the DOJ confirms systemic problems, it can sue and obtain a consent decree requiring changes to policy, training, and oversight. These investigations have produced meaningful reforms in several departments, but they take years, consume significant resources, and depend heavily on the priorities of the sitting administration.
