"Chicago has spent more than half a billion dollars to settle claims of police misconduct since 2004. But in half of those cases, police did not conduct disciplinary investigations... The Justice Department criticized the city for failing to investigate anonymous complaints or those submitted without a supporting affidavit and for having a “pervasive coverup culture.” ...witnesses and accused officers were frequently never interviewed at all, that evidence went uncollected and that witnesses were routinely coached by union lawyers ..."

So much for the naive belief that the problem is a few "rogue" officers.  This is systemic.

Seems nothing's really changed since the 1968 Democratic convention...although, it might have actually gotten worse...
