"In the era of colorblindness," Ms. Alexander writes, "it is no longer socially permissible to use race, explicitly, as a justification for discrimination, exclusion and social contempt. So we don't. Rather than rely on race, we use our criminal justice system to label people of color 'criminals' and then engage in all the practices we supposedly left behind. Today it is perfectly legal to discriminate against criminals in nearly all the ways that it was once legal to discriminate against African-Americans. Once you're labeled a felon, the old forms of discrimination — employment discrimination, housing discrimination, denial of the right to vote, denial of educational opportunity, denial of food stamps and other public benefits, and exclusion from jury service — are suddenly legal."
