The Chicago Police Department, often shortened CPD, is the organization responsible for law enforcement in the city of Chicago.
The Chicago Police Department immediately dispatched officers across the city when Glenn Talbot attacked Chicago in search for Gravitonium, in order to evacuate the civilians and get them to safety. Zbyszewski even went to confront Talbot and got ready to engage him, however, the police received a call from Alphonso Mackenzie who instructed them not to and instead asked them for help in the coordination of the city's evacuation. The officers then led the civilians to the Zephyr One so S.H.I.E.L.D. could take them to a safe place.
