OEMC FOIA: Updated Police C4S Data

CJP seeks to update our police C4S data (call for service) from the Office of Emergency Management and Communications. As they require we have filed another FOIA request with the agency to seek an update to our multi-year data set that we already have in house.

This C4S data is vital to understanding what we call inputs to the Chicago Police Department. These are can provide evidence of dispirit responses to calls for help to the Chicago Police Department. This C4S data is also vital to the police staffing and allocation reports that police departments all over the country do to determine how many officers the department needs and how those officers should be allocated throughout the department.
