'The Black Lost and Found': African Americans now comprise more than half of all prisoners

Forty years ago, the Kerner Commission concluded in its landmark study of the causes of racial disturbances in the United States in the 1960s: "Our nation is moving toward two societies, one black, one white -- separate and unequal." Today we are still moving toward two societies: one incarcerated and one not. The Pew Center on the States released a study in February showing that for the first time in this country's history, more than one in every 100 adults is in jail or prison. According to the Justice Department, 7 million people -- or one in every 32 adults -- are either incarcerated, on parole or probation or under some other form of state or local supervision.

These figures understate the disproportionate impact that this bold and unprecedented social experiment has had on certain groups in U.S. society. Today one in nine young black men is behind bars. African Americans now comprise more than half of all prisoners, up from a third three decades ago.

Sen. James Webb (D-Va.) held a remarkable set of hearings last October on mass incarceration in the United States. In his opening statement, Webb noted that "the United States has embarked on one of the largest public policy experiments in our history, yet this experiment remains shockingly absent from public debate."

The leading presidential candidates have not identified mass imprisonment as a central issue, even though it is arguably the country's top civil rights concern. Many of today's crime control policies fundamentally impede the economic, political and social advancement of the most disadvantaged blacks and members of other minority groups. Prison leaves them less likely to find gainful employment, vote, participate in other civic activities and maintain ties with their families and communities.
