Chicago Mayor Rahm Emanuel rolled out a couple of new strategies yesterday in response to growing criticism over the city's homicide rate. The mayor said that the Chicago Police Department will work with the Buildings Department on securing, and maybe demolishing, 200 vacant buildings. Some of these vacant buildings, Emanuel said, are a haven for gangs. Also, Emanuel identified 37 "problem businesses" the city identified as fostering criminal and gang activity: Some of businesses may get a warning; others might close down.

While overall crime is down in the city this year compared to last, murders are up 37.8 percent.
