Check out this map, via Business Insider, which sheds light on the extent of Chicago's violent crime wave:
Illinois has the most restrictive carry laws in the country, and Chicago has one of the toughest gun-control regulations among cities. Yet, the murder rate for Illinois is above the national average, according to the FBI (5.5 per 100,000 in 2010, compared to 4.8 murders for the rest of the country), as is the state’s violent crime rate (435.2 incidents per 100,000 compared to 403.6 nationally). Chicago recently lost a gun-control case at the Supreme Court (McDonald v. Chicago), but the city lost the gun-control argument years ago — considering that its murder rate is 18th among large American cities at 15.2 per 100,000, more than three times the national average. Washington D.C., which in 2008 lost its own Supreme Court gun control case, ranked seventh in 2010 with a 21.9 rate. For the record, Aurora’s murder rate was 7.1 per 100,000 in 2010, while other Colorado cities were significantly lower: 5.0 for Colorado Springs and 3.6 for Denver.
