TIME: Your book Just Mercy is about getting legal help for poor people in Alabama. What are the biggest impediments? BRYAN STEVENSON (Lawyer and founder of the Equal Justice Initiative): We have a criminal-justice system that treats you better if you're rich and guilty than if you're poor and innocent. I don't believe that America's system is shaped by culpability. I think it's shaped by wealth. TIME: 1 in 3 black men in the U.S. under 30 is in jail, on probation or on parole. Is this the scariest stat? STEVENSON: That 1 in 3 black males born in 2001 is expected to go to jail or prison during their lifetimes is more astonishing because it's about the future. And 1 in 6 Latino boys. That wasn't true in the 20th century. TIME: What do you say to people who say, It's easy to not go to jail-don't commit a crime"? STEVENSON: In this country we have a presumption of guilt that follows young kids of color. I've represented 10-year-olds being prosecuted as adults. They are put in an adult jail. It's so unnecessary-we have juvenile facilities. No one defends it, and yet we still have 10,000 children in an adult jail or prison. TIME: What's the role of the corporations that build prisons? STEVENSON: Corporations have really corrupted American criminal justice by creating these perverse incentives where they actually pay legislators to create new crimes so that we can maintain these record-high-level rates of imprisonment. These companies spend millions of dollars a year on lobbying. Prison spending has gone from $6 billion in 1980 to $80 billion today.
