By James Forman, Jr. Locking Up Our Own: Crime and Punishment in Black America. In recent years, America’s criminal justice system has become the subject of an increasingly urgent debate. Critics have assailed the rise of mass incarceration, emphasizing its disproportionate impact on people of color. As James Forman, Jr., points out, however, the war on crime that began in the 1970s was supported by many African American leaders in the nation’s urban centers. In Locking Up Our Own, he seeks to understand why. Forman shows us that the first substantial cohort of black mayors, judges, and police chiefs took office amid a surge in crime and drug addiction. Many prominent black officials, including Washington, D.C. Mayor Marion Barry and federal prosecutor Eric Holder, feared that the gains of the civil rights movement were being undermined by lawlessness?and thus embraced tough-on-crime measures, including longer sentences and aggressive police tactics. In the face of skyrocketing murder rates and the proliferation of open-air drug markets, they believed they had no choice. But the policies they adopted would have devastating consequences for residents of poor black neighborhoods. Farrar, Straus and Giroux (2017), English, 320 pages.
