A customer inspects a 9mm handgun at Rink's Gun and Sport in the Chicago, suburb of Lockport, Illinois in this June 26, 2008 file photograph. Thanks to a Supreme Court ruling on June 28, 2010 undermining Chicago's strict handgun ban, law-abiding residents will soon be able to legally own a handgun. A report last year by the University of Chicago's Crime Lab estimated that each gunshot wound victim costs the city $1 million in medical, law enforcement and other costs, and each murder caused the departure of 70 people from the city.
