Does gun control work?
There are exactly zero firearms dealers and public shooting ranges in Chicago but that didn't stop dozens of people from getting shot last weekend.
Almost 100 people were shot in the Windy City over the weekend, according to the latest reports, and those numbers will probably be higher by the time you read this (sometimes it takes each police precinct a few hours to update these numbers).
The long holiday weekend is officially over, and ABC 7 Chicago found nearly 100 people were shot in Chicago since Friday night.
Chicago Police Superintendent David Brown will address the violence and face questions about the department's safety plan Tuesday afternoon.
A 15-year-old boy is one of the latest victims.
There were at least 17 killed.
This year's CPD safety plan going into the weekend included targeted protection for commercial districts across the city.
Officers also had days off canceled, and worked 12-hour shifts, as the strategy included focusing on 15 violence-prone areas in Chicago.
Chicago Police Superintendent David Brown praised the work of his officers on Twitter, writing that they, "continue to work tirelessly to keep our city safe."
CHICAGO, IL - JANUARY 02: A rosary and gang symbols are part of a memorial created in an alley near the spot where 20-year-old Octavius Dontrell Lamb was shot yesterday and killed, on January 2, 2013 in Chicago, Illinois. At 3:45 a.m., less than four hours into the new year, Lamb became the first murder victim of 2013 in Chicago, a city which saw more that 500 murders in 2012. Fifteen people were shot in Chicago on the first day of the year, three fatally. Aurora, Illinois' second largest city, had no murders in 2012. (Photo by Scott Olson/Getty Images)
