2009 Pulitzer Prize Non-Fiction winner " Slavery by Another Name: The Reenslavement of Black Americans from the Civil War to World War Two" by Douglas A. Blackmon is banned reading by Montgomery Alabama Kilby Correctional Facility staff. It's considered a "security threat" because it describes how prisoners were leased to what amounted to slave labor. The authorities in question claim that the book breaks a rule which bans material that "incites violence based on race, religion, sex, creed, or nationality or incites disobedience toward law enforcement officials or correctional staff."
