Dozens of Baltimore police officers trudged through a housing project yesterday afternoon, passing out fliers and hoping to turn up tips on recent shootings, the Baltimore Sun reports. Battered by 27 shootings that claimed nine lives over five days, police need help to make arrests and prevent additional violence. Deputy Police Commissioner John Skinner said crime-weary residents have been coming forward. “We have incredible leads on some of these incidents, and those are coming from the neighborhoods themselves,” Skinner said. “We’re hoping to hone in on those tips and hold people accountable.” A nonprofit that works with city youth called The Intersection launched a “listening campaign” to draw awareness to urban gun violence. Organizer Zeke Cohen, noted that more people were killed in Baltimore in 2012 than those in mass shootings in Aurora, Newtown, Columbine, and Virginia Tech combined.
