But now he's twisting in the wind.
From ABC Chicago:
The investigation portrayed a police force corroded by the use of unreasonable force - many times prompted by a factor of racism - and protected by a code of silence. The deadly force and racism issue went uncontrolled because of a lack of training, according to the DOJ report.
"We found CPD officers do not fully report their uses of force and that supervisors are not appropriately reviewing these uses of force. We found that Chicago's accountability systems are broken. Many complaints that should be investigated are not," said Principal Deputy Assistant Attorney General Vanita Gupta, head of the Civil Rights Division.
From officers falsifying reports, to lying in court testimony, to cover-ups of misconduct and crime data, the DOJ report summed up the city's thick blue curtain.
"For decades, Chicago has failed to develop a comprehensive, integrated system to track and make public basic information about its police force," the report said.
