This document summarizes key points from Michelle Alexander's book "The New Jim Crow: Mass Incarceration in the Age of Colorblindness". It notes that incarceration rates in the U.S. increased dramatically from 1980 to 2009, and that African Americans are incarcerated at six times the rate of whites. It then provides brief biographical information about Alexander and outlines some of the challenges and criticisms to her argument that the U.S. criminal justice system functions as a "new Jim Crow" system of racial control similar to the old Jim Crow laws.
