OEMC Missing Event Data Problems

MissingMissing data among the event types within the data from the Office of Emergency Management and Communications (OEMC) is nothing new to CJP. We have wages a quiet war for many years to get OEMC to rectify the missing data between the Event Types document (embedded below) they hand out through FOIA and what is found in the actual police call for service data.

Event Types: Are codes used by OEMC call takers to categorize the reasons people are calling 911 requesting police services. This data is used for all kinds of statistical analysis including determining staffing and resource allocation. It is also communicated to police officers so they know how quickly they need to respond to calls and what it is they should be expecting when they arrive on scene.

This document should contain all the information about all the event types that are present in the data OEMC maintains. Unfortunately there has always been missing data that they agency cannot be bothered to address. You would think an agency tasked with such important work would make sure there was no missing data in they data they produce. For over a decade every time we have FOIAed data from OEMC there has been missing event types that the agency just refuses to address.

CJP maintains a data warehouse of metadata on some 55 + million calls for police service – calls to 911 seeking police assistance. Once again we are in a position where OEMC has supplied us a document that lists all the event types according to OEMC but in actuality the data in our warehouse contains dozens of event types that are not found within the document.

This FOIA request is our attempt to get OEMC to fess up about why the discrepancies exist and what the event types stand for. We have tried this multiple times throughout the years without any success. This time we are committed to suing to force the agency to come clean.

This is just another example of the incompetence and corruption found within Chicago justice system. It will be interesting to see if the response we get back from OEMC is any different in the Lightfoot era. Somehow, we feel it will not be any different.
