This book reproduces the complete report from the U.S. Department of Justice (DOJ) Civil Rights Division about the practices of the Chicago Police Department (CPD), along with the agreement in principle between the DOJ and the city of Chicago, as released in January 2017. Introduction * 1. Investigation of the Chicago Police Department / United States Department of Justice Civil Rights Division and United States Attorney's Office Northern District of Illinois / January 13, 2017 * 2. Agreement in Principle Between The United States Department of Justice and the City of Chicago Regarding the Chicago Police Department * 3. Factsheet * 4. Police Reform and Accountability Accomplishments The city of Chicago and the Justice Department have signed an agreement in principle to work together, with community input, to create a federal court-enforceable consent decree addressing the deficiencies found during the investigation. "One of my highest priorities as Attorney General has been to ensure that every American enjoys police protection that is lawful, responsive, and transparent," said Attorney General Loretta E. Lynch. "Sadly, our thorough investigation into the Chicago Police Department found that far too many residents of this proud city have not received that kind of policing. The resulting deficit in trust and accountability is not just bad for residents - it's also bad for dedicated police officers trying to do their jobs safely and effectively. With this announcement, we are laying the groundwork for the difficult but necessary work of building a stronger, safer, and more united Chicago for all who call it home." "The failures we identified in our findings - that we heard about from residents and officers alike - have deeply eroded community trust," said Principal Deputy Assistant Attorney General Vanita Gupta, head of the Civil Rights Division. "But today is a moment of opportunity, where we begin to move from identifying problems to developing solutions. I know our findings can lead to reform and rebuild community-police trust because we've seen it happen in community after community around the country over the past 20 years." "The findings in our report, coupled with the City of Chicago and Police Department's commitment to work together with us, are an historic turning point and a major step toward sustained change," said U.S. Attorney Zachary T. Fardon of the Northern District of Illinois. "Implementing these findings is a necessary precursor to our long-term success in fighting violent crime in Chicago." On Dec. 7, 2015, Attorney General Lynch announced the investigation into the CPD and the city's Independent Police Review Authority (IPRA). The investigation focused on CPD's use of force, including racial, ethnic and other disparities in use of force, and its systems of accountability. In the course of its pattern or practice investigation, the department interviewed and met with city leaders, current and former police officials, and numerous officers throughout all ranks of CPD. The department also accompanied line officers on over 60 ride-alongs in every police district; heard from over 1,000 community members and more than 90 community organizations; reviewed thousands of pages of police documents, including all relevant policies, procedures, training and materials; and analyzed a randomized, representative sample of force reports and the investigative files for incidents that occurred between January 2011 and April 2016, including over 170 officer-involved shooting investigations and documents related to over 400 additional force incidents.
