At 24, Jarrell Daniels was released from prison after six years behind bars. It was a Thursday. The following Tuesday, he came back to the same facility in street clothes to attend the college class he’d started on the inside. He’s now a sophomore at Columbia University. The class that so inspired him was a novel experiment in an already unconventional setting: half of the students were people incarcerated in the facility, and half were local prosecutors. Their subject was the criminal justice system. Hear more about the experience, now being replicated by other district attorney’s offices, from Daniels, and from Lucy Lang, who conceived of the idea. A former Manhattan assistant district attorney, Lang is now the executive director of the Institute for Innovation in Prosecution.
