““Hitler, Stalin, and Pol Pot all employed mass imprisonment, each presiding over a process that arrested and incarcerated millions. Such systems are often part of massive programs of slave labor or forced resettlement, in which high death rates are a typical by-product. And some examples of mass incarceration are explicitly part of a program of ethnic cleansing or genocide—a tool of policy that intends the extermination of entire populations. But now, for the first time, we see mass incarceration in a democratic society.””
