Chicago police exchanged gunfire with looters and arrested more than 100 people after crowds swarmed Chicago's luxury commercial district early Monday, looting stores, smashing windows and clashing with officers for hours, police said. Police Superintendent David Brown called the outbreak "pure criminality," and Mayor Lori Lightfoot sought to distance the incident from the "righteous uprising" in response to the death of George Floyd at the hands of Minneapolis police on May 25. "This was not an organized protest. Rather this was an incident of pure criminality," Brown told a news conference.
