There are murders. There are shootings. They happened after the protests, riots and lootings in Minneapolis following the killing of George Floyd. Paul Cassell calls it the “Minneapolis Effect.”
The homicide spikes began in late May. Before May 28, Chicago had almost the same number of homicides as in 2019. Then, on May 31, 18 people were murdered in Chicago—the city’s most violent day in six decades. Violence continued through the summer. July was Chicago’s most violent month in 28 years. As of Sept. 1, murder is up 52% for the year, according to Chicago Police Department data.
What changed in late May? The antipolice protests that began across the country around May 27 appear to have resulted in a decline in policing directed at gun violence, producing—perhaps unsurprisingly—an increase in shootings.
