Based on the memoir of Brian Stevenson, a defence attorney for poor people and minorities in the Southern States, this film gives us to understand a couple of things. One is that the African American holocaust is divided into three stages, the last of which is still in operation. First it was slavery, then lynchings, and then incarceration. A large number of the prison sentences, disproportionately given to black men, are from bad trials, and worse sentencing, leading up to decades of jail time, and, sometimes, placement on death row.
