Read the excerpt from Just Mercy by Bryan Stevenson. The collateral consequences of mass incarceration have been equally profound. We ban poor women and, inevitably, their children from receiving food stamps and public housing if they have prior drug convictions. We have created a new caste system that forces thousands of people into homelessness, bans them from living with their families and in their communities, and renders them virtually unemployable. Some states permanently strip people with criminal convictions of the right to vote; as a result, in several Southern states disenfranchisement among African American men has reached levels unseen since before the Voting Rights Act of 1965.

We also make terrible mistakes. Scores of innocent people have been exonerated [cleared] after being sentenced to death and nearly executed. Hundreds more have been released after being proved innocent of noncapital crimes through DNA testing. Presumptions of guilt, poverty, racial bias, and a host of other social, structural, and political dynamics have created a system that is defined by error, a system in which thousands of innocent people now suffer in prison.
