Inside Chicago trauma unit

On Monday, July 9, 2012, Mayor Rahm Emanuel announced a new attack on gangs. He told CBS News' Scott Pelley that, while other classifications of crime (i.e., burglary, armed robbery) are down in Chicago by ten percent, "We have a gun violence issue specifically tied to gangs. So we have readjusted the strategy" addressing such violence.

Among the tactics: Closing liquor stores in communities "that are a magnet and a cancer on a community, for gangs and narcotics"; boarding up or tearing down abandoned buildings used by gangs for their operations; and holding police commanders and district leaders accountable for results.

"You have be very aggressive in making sure that the gangbangers know that the police force and the community run those streets, they don't," Emanuel said.
