Mark J. Konkol and Frank Man are doing a remarkable job detailing the reasons behind the CPD’s difficulty in clearing homicides.

And I’d missed this earlier (via Second City Cop):

Police statistics suggest it’s getting increasingly dangerous on the street for officers. Nearly 3,160 officers reported they were victims of assault and battery in 2008, almost double the 1,583 officers who said they were attacked in 2003. About 35 percent of those officers in 2008 were injured, according to the department.
