Have a reaction. Write, mope, or construct an argument here at the consent decree portal before the end of the day Friday, August 17. A longer version of this shortened draft available here. Data to support this at bottom of post and tabulated on my own spreadsheet based on these sources, which anyone is welcome to comment on or question. Occasionally, I’ll make small updates for greater accuracy.

MY OPEN LETTER TO CHICAGO:
Stripping Context from Media & Government Reports on Police Abuse a Likely Cause of More American and Chicago Bloodshed

Statistical-Based Evidence Undermines Consent Decree Logic that Throws Chicago Police Under the Bus

How Does That Work? Just Check These Charts:

Go to page 19 of the PDF for the Center for Policing Equity’s conclusions on use of force disparities. Blacks receive slightly more use of force in all but one category: Lethal force.
Combined, the rate of all force (lethal and non-lethal) per arrest in 12 major municipalities is 3.6 per 100 (white) vs. 4.6 per 100 (black).
Full math at the bottom of this posting. But here are the basics. For Chicago, I divided the average annual instances of use of force over a 5-year period (3,693 for blacks, 383 for whites) with the arrests for the same period (92,328 for blacks, 11,541 for whites). The arrest percentage in 2009 and 2010 for blacks and whites are the same, 9% and 72% respectively. With those computations, the rate of all force (lethal and non-lethal) per arrest in Chicago is 3.3 per 100 (white) vs. 4.0 per 100 (black).

What Can Explain That Difference?

Chicago source data & national source data.

CPD Are “Average”

Source data (USA is average of Washington Post and Guardian data).
Accurate Chicago police and crime data, with healthy dose of cynicism, here on HeyJackass.com

The Death Count

Chicago Police Superintendent Eddie Johnson, Mayor Rahm Emanuel and Illinois Attorney General Lisa Madigan at a news conference July 27, 2018, announcing the release of the draft consent decree.
