The city of Chicago’s plan to deter violence this summer and prevent a repeat of the chaos experienced in the Loop several weekends ago while the city experienced unseasonably warm weather includes a heavier police presence in Millennium Park, at the lakefront beaches and on CTA trains and buses.  

Bag checks are also expected to be performed at the beaches and Millennium Park, and police plan to have an increased number of so-called “prisoner vans” in use.
