Several local social-action groups are teaming up to sponsor a panel discussion about incarceration and racial inequality next week. “Mass Incarceration & Racial Inequality: The New Jim Crow” will be held Nov. 7 from 6:30 p.m. to 8:30 p.m. in Hunneman Hall at the Public Library of Brookline, 361 Washington St. Speakers will include Lois Ahrens, founder of the Real Cost of Prisons Project; Carl Williams, a racial-justice lawyer for the American Civil Liberties Union of Massachusetts; and former Boston city councilor Chuck Turner, who was recently released from federal prison following a bribery conviction. MassOccupy/Brookline is presenting the panel, with cosponsors including the League of Women Voters of Brookline and Brookline PAX. Copies of Michelle Alexander’s book, “The New Jim Crow,” will be available for purchase at the event.
