Criminal justice in the United States describes the institutions, laws, policies, and practices involved in preventing, investigating, prosecuting, adjudicating, and punishing crime across the United States. It encompasses federal, state, tribal, and local systems shaped by landmark events, statutes, and decisions from the Constitution of the United States era through modern reforms such as the Violent Crime Control and Law Enforcement Act and the First Step Act. The system interrelates agencies like the Federal Bureau of Investigation, the Department of Justice (United States), and state counterparts alongside courts such as the Supreme Court of the United States and numerous state supreme courts.
The development traces from colonial charters like the Mayflower Compact and the Articles of Confederation through codification in the Constitution of the United States and the Bill of Rights, with pivotal moments including the Civil War and Reconstruction, which produced amendments such as the Thirteenth Amendment and the Fourteenth Amendment. Progressive Era reforms influenced by figures like W. E. B. Du Bois and institutions such as the National Probation Association gave rise to probation and parole models mirrored in later programs like the Comprehensive Crime Control Act of 1984. The 20th century saw expansions in federal jurisdiction via statutes like the RICO Act and the creation of agencies including the Drug Enforcement Administration and the Bureau of Alcohol, Tobacco, Firearms and Explosives; post-9/11 changes involved the USA PATRIOT Act and the Department of Homeland Security.
The system comprises three principal components: law enforcement agencies (federal, state, and local), prosecutorial and defense functions centered in offices like the United States Attorney General and state attorneys general, and adjudicative bodies such as the United States District Courts and state trial courts. Correctional institutions range from local jails to federal facilities managed by the Federal Bureau of Prisons, and include community-based programs administered by entities like the Pew Charitable Trusts and the National Institute of Justice. Oversight and reform are influenced by landmark rulings from the Supreme Court of the United States and statutes like the Civil Rights Act that affect policing, sentencing, and incarceration.
Law enforcement is decentralized, spanning agencies such as the Federal Bureau of Investigation, the Drug Enforcement Administration, state patrols like the California Highway Patrol, and municipal departments like the New York City Police Department and the Chicago Police Department. Policing practices have been shaped by events like the Watts riots and the Ferguson unrest, and guided by doctrines adjudicated in cases such as Miranda v. Arizona and Terry v. Ohio. Standards-setting organizations and reforms involve groups such as the International Association of Chiefs of Police and legislation like the Posse Comitatus Act in relation to military involvement.
Adjudication occurs in a dual court system: federal courts culminating in the Supreme Court of the United States and state court hierarchies culminating in state supreme courts like the New York Court of Appeals and the Supreme Court of California. Key procedural protections derive from decisions such as Gideon v. Wainwright, Miranda v. Arizona, and Brown v. Board of Education in broader civil contexts. Prosecutors including United States Attorneys and state district attorneys exercise charging discretion, while defense counsels may be public defenders organized under entities like the Federal Public Defender offices or private bar associations including the American Bar Association.
Corrections encompass incarceration in facilities run by the Federal Bureau of Prisons, state departments of correction such as the Texas Department of Criminal Justice, and private operators like GEO Group and CoreCivic. Sentencing frameworks include determinate and indeterminate models and were shaped by statutes like the Sentencing Reform Act of 1984 and the federal Mandatory minimum sentencing regime. Reentry programs involve partnerships with organizations such as the Pew Charitable Trusts, the Urban Institute, and faith-based groups, while policy debates cite examples like the Three-strikes law and reforms under the First Step Act.
Juvenile systems evolved from reformatories influenced by figures like John Augustus and institutions including the Juvenile Court (Cook County); modern policy is shaped by rulings such as Roper v. Simmons and Miller v. Alabama. Juvenile courts, diversion programs, and detention centers interact with child welfare agencies like the Administration for Children and Families and advocacy groups such as the Annie E. Casey Foundation. Debates center on transfer laws, rehabilitation, and racial disparities illustrated by studies from the Sentencing Project and interventions funded by the Office of Juvenile Justice and Delinquency Prevention.
Critiques focus on mass incarceration trends exemplified by the high populations in systems like those of Louisiana and Texas and on racial disparities highlighted by activists such as Angela Davis and organizations like the ACLU. Other concerns include police misconduct cases involving departments such as the Los Angeles Police Department and outcomes analyzed in inquiries like the President's Task Force on 21st Century Policing. Sentencing disparities linked to laws like the Anti-Drug Abuse Act of 1986 and the impact of private prisons operated by firms such as CoreCivic drive reform movements including campaigns by The Sentencing Project and legislative efforts like the First Step Act and state ballot initiatives in places such as California and Florida.
