An outspoken author and journalist, Boston’s police commissioner and a former prison psychologist will take on the issue of guns and violence in a panel discussion. UMass Lowell’s “A Day Without Violence” will feature keynote speaker Craig Whitney, author of “Living with Guns: A Liberal’s Case for the Second Amendment”; Boston Police Commissioner Ed Davis; and Cathy Levey, a member of UMass Lowell’s criminal justice faculty who has more than 20 years of experience working as a Connecticut prison system psychologist.

Each year, college and university campuses nationwide observe “A Day Without Violence” in honor of Rev. Martin Luther King Jr.’s quest for social justice and equality. UMass Lowell’s observance is presented by the university’s Peace and Conflict Studies Institute, the Greeley Scholar for Peace Studies Program and the Center for Arts and Ideas. The program is free and open to the public.
