The genius of the current caste system, and what most distinguishes it from its predecessors, is that it appears voluntary. People choose to commit crimes, and that's why they are locked up or locked out, we are told. This feature makes the politics of responsibility particularly tempting, as it appears the system can be avoided with good behavior. But herein lies the trap. All people make mistakes. All of us are sinners. All of us are criminals. All of us violate the law at some point in our lives. In fact, if the worst thing you have ever done is speed ten miles over the speed limit on the freeway, you have put yourself and others at more risk of harm than someone smoking marijuana in the privacy of his or her living room. Yet there are people in the United States serving life sentences for first-time drug offenses, something virtually unheard of anywhere else in the world.

Vagrancy laws and other laws defining activities such as mischief and insulting gestures as crimes were enforced vigorously against blacks. The aggressive enforcement of these criminal offenses opened up an enormous market for convict leasing.

The rhetoric of ‘law and order’ was first mobilized in the late 1950s as Southern governors and law enforcement officials attempted to generate and mobilize white opposition to the Civil Rights Movement. In the years following Brown v. Board of Education, civil rights activists used direct-action tactics in an effort to force reluctant Southern States to desegregate public facilities. Southern governors and law enforcement officials often characterized these tactics as criminal and argued that the rise of the Civil Rights Movement was indicative of a breakdown of law and order. Support of civil rights legislation was derided by Southern conservatives as merely ‘rewarding lawbreakers.’ For more than a decade – from the mid 1950s until the late 1960s – conservatives systematically and strategically linked opposition to civil rights legislation to calls for law and order, arguing that Martin Luther King Jr.’s philosophy of civil disobedience was a leading cause of crime.

Arguably the most important parallel between mass incarceration and Jim Crow is that both have served to define the meaning and significance of race in America. Indeed, a primary function of any racial caste system is to define the meaning of race in its time. Slavery defined what it meant to be black (a slave), and Jim Crow defined what it meant to be black (a second-class citizen). Today mass incarceration defines the meaning of blackness in America: black people, especially black men, are criminals. That is what it means to be black.
