After the U.S. Supreme Court struck down Chicago's nearly 30-year-old handgun ban, the city council passed an ordinance allowing residents to own a handgun if they meet certain requirements.
Residents must pass a criminal background check, take a four-hour class on firearms and spend an hour on a shooting range.
Police say in the past year, 3,500 city residents applied for handgun permits. The city approved 98 percent of those applications.
