"Every year Chicago Police recover more illegal guns than officers in any other city, and as more and more illegal guns continue to find their way into our neighborhoods it is clear we need stronger state and federal gun laws," Guglielmi said in the statement. "So far this year, the majority of the gun violence we've seen are a result of chronic gang conflicts driven in part by social media commentary and petty disputes among rival factions. Despite an overall lack of cooperation from gang members, detectives are working aggressively and making optimistic progress in several cases."
