"More than 5,000 walkers – many of them families who have lost loved ones to violence – will participate on Sunday in the 17th Annual Mother's Day Walk for Peace in Dorchester to pledge their commitment to peace and shine a light on the ongoing problem of gun violence in our communities. ""For more than 17 years, the Louis D. Brown Peace Institute has been an ally to the City of Boston, working hard to make Boston's neighborhoods safer,"" says Mayor Thomas Menino. ""Today, a commitment to peace is needed now more than ever."" A special section on the Walk is enclosed in today's issue of the Reporter. Photo: Louis D. Brown Peace Institute"
