Just before the long Memorial Day weekend began, Chicago’s new mayor was joined by Police Superintendent Eddie Johnson and other community leaders as she detailed her plan for ensuring safety and preventing a surge in summer violence.
Lightfoot joined the Chicago Police Department and other agencies Friday to highlight the role authorities have in keeping the city safe.
“As my mother would say, if people are ‘acting a fool,’ there will be consequences,” Lightfoot said.
The plan includes an additional 1,200 officers on patrol and a special mass transit detail for trains and bus lines. Officers will also patrol high-traffic areas like beaches and popular downtown spots like Michigan Avenue as part of the city’s Summer Mobile Team.
34 shot, 5 fatally, so far in Chicago during Memorial Day weekend
By Sunday evening of Memorial Day weekend, Chicago police had responded to the shootings of 34 people, five of whom died of their injuries, officials said.
The grim tally grew as a shooting Sunday about 6 a.m. in the 1300 block of West Hastings Street left two dead and three injured. The shooting was possibly in retaliation for an earlier one in the same University Village neighborhood where large crowds had gathered, and which also left a man dead, investigators said.
