ANN ARBOR, Mich. (AP) — Exploring the role that the arts can play in overhauling the criminal justice system is the subject of a conference at the University of Michigan. The Michigan Art for Justice Forum , scheduled for Tuesday at the Michigan Union, is expected to draw lawmakers, artists, advocates and former prisoners. The free, public event is billed as the first in a series of a half-dozen national forums designed to explore what organizers call "the mass incarceration crisis" and identify solutions.
