FOIA: DC Office of Unified Communications

UnifiedThis request submitted to the Office of Unified Communications is part of our first set of requests in the District of Columbia (DC). This request is targeting meta data on calls to 911 within DC seeking police services.

As is CJP’s policy we are targeting data for as far back as the Office of Unified Communications maintains data and will use litigation if necessary to make sure this data is regularly updated.

While this data is often ignored by the stakeholders, policymakers, and the media it is in fact very powerful. This data is routinely used as the basis for staffing analyses conducted throughout the policing community in America. This is exactly what we will be using this data. There is no reason these analyses have to be done secretly within police departments. This is a perfect example of when science can make a meaningful contribution to a vital public issue.

DC has a completely unique justice system to engage because it is bifurcated. While DC does maintain their own police department, the Metropolitan Police Department (MPD), and their own 911 system, the Office of Unified Communications, the remaining pieces of the justice system are mostly on the federal level.

According to sources within DC government about 60% of the arrests that occur within DC are actually made by the MPD. The rest of the arrests are spread out between the US Park Police, US Capital Police, and the Metro Transit Police. The Metro Transit Police are actually funded by DC, Virginia, Maryland, and the federal government. We will be engaging each of those agencies to open their data as well in the near future.
