13th

The loophole in the amendment

13th is a 2016 documentary directed by Ava DuVernay, who wrote it with its editor, Spencer Averick. Its title points to the Thirteenth Amendment to the US Constitution, adopted in 1865. The amendment ends slavery and involuntary servitude, with one exception: "as a punishment for crime." DuVernay builds the whole documentary on that clause.

Her argument is simple to state. Slavery did not end in 1865. It changed its form. The exception let states turn Black Americans into "criminals" and then take their labor, their votes and their freedom by law. Each later era, the documentary argues, found a new tool for the same job.

The documentary opens with an audio clip of President Barack Obama, who says the United States has 5 percent of the world's population and 25 percent of its prisoners. From there, it moves through history in three broad chapters, with hip-hop songs as breaks between them. Interviews carry the argument. The speakers include the scholar and activist Angela Davis, the lawyer Bryan Stevenson, the legal scholar Michelle Alexander, the historian Henry Louis Gates Jr., the journalist Jelani Cobb, the commentator Van Jones, the political scientist Marie Gottschalk and the activist Malkia Cyril. DuVernay also interviews politicians from both parties, including Newt Gingrich and Cory Booker.

From convict leasing to Jim Crow

The first chapter covers the years after the Civil War. The documentary argues that the Southern economy lost its unpaid workforce and moved fast to replace it. States passed laws against minor acts such as loitering and vagrancy. Police arrested freed Black people under these laws. When they could not pay fines, the state leased them to plantations, mines and railroads. This system is convict leasing. DuVernay presents it as slavery under a new name, and she argues it gave the state a reason to criminalize more behavior.

The documentary then turns to images. It shows scenes from The Birth of a Nation (1915), which portrays Black men as a threat to white women and presents the Ku Klux Klan as heroes. Speakers argue that this image of the Black man as a dangerous criminal outlived the movie and still shapes how people see crime. The documentary links it to the wave of lynchings and to the Jim Crow laws that enforced segregation and kept Black citizens off voter rolls and juries.

The civil rights movement ended legal segregation in the 1960s. DuVernay shows activists being arrested for protest, and she argues that the arrest record became a new tool against the movement.

Law and order, and the war on drugs

The second chapter is about national politics. The documentary argues that as legal segregation ended, politicians found a coded language for race in "law and order." It shows Richard Nixon's campaign on crime and his declaration of a war on drugs, and it presents both as a strategy to win white voters in the South.

Under Ronald Reagan, the documentary says, the war on drugs grew into a war on drug users. It focuses on the gap in sentences for crack cocaine and powder cocaine, and argues that this gap fell hardest on Black neighborhoods. News images of "crack" and of young Black men in handcuffs fed public fear.

DuVernay does not let Democrats off the hook. The documentary shows Bill Clinton's 1994 crime law, with its "three strikes" rules, mandatory minimum sentences and money for more police and prisons. It notes Hillary Clinton's support for that agenda. Speakers describe a contest in which both parties tried to look tougher on crime. The documentary also shows some of the politicians who backed these policies expressing regret.

The documentary's charts show the number of people in prison climbing year after year from the 1970s. Speakers argue that prison numbers rose because of policy choices, not because of crime alone.

Who profits from prisons

The third chapter follows the money. The documentary argues that a large web of private interests now depends on keeping prisons full. It names the American Legislative Exchange Council (ALEC), a group in which corporations and state lawmakers draft model bills. The documentary argues that ALEC helped spread laws such as "truth in sentencing" and "stand your ground," and that member companies profited from them. It names the private prison company Corrections Corporation of America as one beneficiary.

DuVernay widens the view beyond private prisons. The documentary points to companies that sell prison phone calls, commissary goods and food, and to the bail system that keeps poor people in jail before trial. It describes plea bargains in which defendants, many of them innocent, the speakers say, accept guilt to avoid a much longer sentence at trial. It also looks at immigrant detention, which it presents as a new growth market for the same companies. Speakers warn that reforms such as electronic monitoring could simply move the profit from the cell to the ankle bracelet.

The term the documentary uses for the whole system is the prison industrial complex.

Faces, footage and the present

The documentary keeps returning to single lives. The most detailed is the story of Kalief Browder, a teenager from the Bronx who was held at Rikers Island for about three years without trial, much of it in solitary confinement, after an arrest for allegedly stealing a backpack. He died by suicide after his release. DuVernay uses his story to show what the bail and plea system can do to one person.

The final part brings the history to the present. DuVernay sets audio of Donald Trump's 2016 campaign rallies against archival footage of violence against Black protesters in the 1960s. She shows the names and images of Black people killed by police or vigilantes, including Trayvon Martin, Philando Castile and Sandra Bland. Speakers present the Black Lives Matter movement as part of a long struggle against criminalization.

The documentary ends with phone and dashboard videos of police killings. The New York Times critic Manohla Dargis called the documentary powerful and infuriating. DuVernay's closing point is that the system is the product of choices, and choices can change.

What the critics say

Most reviews were strongly positive, and the documentary was nominated for the Academy Award for Best Documentary Feature. The historian Dan Berger, writing for Black Perspectives, praised its account of Kalief Browder but argued that it uses outdated statistics and overstates the role of private prisons, prison labor and ALEC; he notes that private prisons hold a small share of US prisoners. Berger also argued that it dates mass incarceration too late and says little about women in prison. In Sight and Sound, Fanta Sylla made a similar point about the criminalization of Black women and girls and questioned whether showing footage of killings changes anything.

Who should watch it

Watch it if you want a clear, compact case for how race, politics and money shaped the American prison system. Pair it with a careful history or policy book to test its numbers, since some of its statistics have dated.
