Today, like any other day, there are around 2.4 million people incarcerated in America’s federal, state, and local prisons and jails. Together, the nation’s inmates would constitute the fourth biggest city in the United States, knocking Houston down a notch. 

Attorney General Eric Holder this week called on states to do away with arcane laws that prohibit more than 6 million felons, most of whom are people of color, from voting in a speech at Georgetown University Law Center. "Those swept up in this system too often had their rights rescinded, their dignity diminished, and the full measure of their citizenship revoked for the rest of their lives," Holder said in the speech. "They could not vote."
