This week, we’re asking experts to give Mayor Rahm Emanuel grades in four key areas that he outlined as priorities during his tenure. Wednesday we’re tackling public safety. How has he battled violence in the city, and what’s his role been in police and community relations? Our panel includes Loyola University Chicago professor Art Lurigio, Chicago Justice Project’s Tracy Siska and Logan Square Organization of Neighbors co-founder Eric Hudson.
