Chicago was not alone. During that weekend in particular, which came after the death of George Floyd after being forcibly detained by Minneapolis police, cities across the United States witnessed spasms of violence.

The year ended in Detroit, Washington, D.C., New York, Milwaukee and other cities with more killings than the year before. The same held true in smaller cities, including Grand Rapids, Michigan, and Rockford, Illinois. Chicago, the nation’s third-largest city, saw hundreds more homicides than either New York or Los Angeles.
