Over the past weekend, at least 72 people were shot in Chicago, with 12 being fatal, but police didn’t record a single arrest, the Chicago Tribune reported.

Mayor Rahm Emanuel and police superintendent Eddie Johnson called on residents to speak up and cooperate with police in an emotional response to the media.

Chicago recorded more than 1,400 homicides and 6,200 shooting incidences in 2016 and 2017. So far, the city has marked 325 murders this year, a 2% drop from the same time in 2017.

But it also comes as Chicago officials solve fewer murders compared to other major departments. The national homicide clearance rate was 59% in 2016, the FBI have estimated. The Chicago homicide clearance rate in 2017 was 17.5%, with only a 5% clearance rate for nonfatal injuries in 2016.

The shootings come after protesters shut down a bridge to protest violence in the city. Some of the shootings over the weekend in Chicago happened at block parties, and of the twelve confirmed victims, three were teenagers, and one was a baby. Chicago is again on track to have the most homicides in any U.S. city.

Mayor Emanuel is facing his own reelection this November, squaring off against republican Garry McCarthy, his former Police Superintendent, who was forced to resign after the poor handling of a dash-cam video that showed Chicago police officers shoot a young black man in 2015.

Last week’s Stateline reported that since the February shooting at Marjory Stoneman Douglass High School, state legislators across the country have begun instating legislation to implement stronger gun control, a reversal from standing trends.

Fifty new laws have restricted access to guns, ranging from the banning of bump stocks, to new court order systems that allows officials to disarm violent people with so called “red-flag” laws.

Stateline noted that in the six years since the Sandy Hook School shooting “hundreds of state gun laws enacted in that time have expanded, rather than restricted, access to firearms,” but that the recent successes at gun control are, according to Mr. Aborn, President of the Citizens Crime Commission of New York City, “the cumulative effect of all of the shootings” since Sandy Hook.

States such as Texas, however, are looking for alternatives to restrictive gun measures, opting instead to increase police presence at schools, arming school staff, and developing mental health screen programs, in the face of their own mass shootings, said Stateline. This may not address a larger gun issue in the state, according to Texas Gun Sense, Texas has the highest child gun homicide rate in the nation.

Voters recently told a Pew Study that second amendment rights were one of their top issues on their minds going into this November election.

McCarthy has the backing of Rudy Giuliani, a member of Trump’s legal counsel and former Republican Mayor of New York City.

McCarthy recently told Fox News that “political manipulation of the police department and the political landscape” created by Rahm Emanuel were “the cause of the violence.”

USA today reported that Pastor Acree, of the west side of Chicago, seemed to state otherwise, saying it was “no coincidence the neighborhoods with the city’s highest poverty rates have the highest homicide rates.”

Stateline noted that some advocates agree that federal legislation is the more definitive tool to address gun violence, but that many advocating for more gun control have believe the most effective route is through state legislation in the face of the stonewalling in Washington. All sides may be looking to the November election to see how much gun violence weighs on voters’ choices.
