Seems legit. After all, Chicago is the city that thought being a "gun free zone" WOULDN'T result in an average of 30 dead by gunshot a weekend (even California can't believe such idiocy)

and those are just the ones the COPS didn't commit:

Chicago Mayor Lori Lightfoot has released an inspector general's report that found that 16 officers took part in a massive cover-up after the 2014 police shooting of Laquan McDonald, an unarmed black teenager.

Officer Jason Van Dyke shot 17-year-old McDonald 16 times. Initial reports indicate that Van Dyke said McDonald lunged at him with a knife, but dashcam footage, released in 2015 after a court order, contradicts that narrative.  4 other officers turned off their dashcams to prevent their dashcams from recording the events, as CPD rules stipulate.

The report also recommended the removal of Lt. Anthony Wojcik, who destroyed evidence and reports with officers' notes from witness statements. Sgt. Stephen Franko who supervised officers handling the case, and 2 other supervisors approved Van Dyke's and other officers' description of events after the shooting, despite knowing the accounts were false, the report concludes.
