In the city of Chicago, where Barack Obama has a home, locals are deeply concerned about one issue that he and his Republican challenger Mitt Romney failed to talk about throughout the presidential campaign - gun control and gun violence.

The city's 438 homicides this year have already exceeded last year's total of 435. It's the first annual increase since 2008, and higher than both New York City and Los Angeles.

Many, such as Tio Hardiman, executive director of CeaseFire Illinois and the creator of the Violence Interrupter Initiative, thinks the homicide number may pass the 500 mark this year.
