Chicago Police Department

Suspects told horrifying stories about being beaten, electro-shocked or suffocated by Jon Burge and his men to elicit confessions.

On the city's South Side, residents and activists converged to protest the deadly shooting of a man Saturday. On Sunday police released a 30-second clip of the incident that set off the protests.

The Cook County grand jury indictment alleges that the three police officers were at the scene of the killing and worked together to conceal crucial facts in order to protect a fellow officer.

An investigation by the Justice Department found that Chicago police are poorly trained in use of force, can easily collude to conceal acts of brutality and are rarely punished for violations.

The investigation found widespread evidence of unconstitutional use of force. It was launched more than a year ago after a black teenager was shot and killed by a white Chicago police officer.

The city's inspector general recommended that 10 officers be fired in connection with the 2014 killing of 17-year-old McDonald. Several of those officers have since retired or resigned.

A report commissioned by Mayor Rahm Emanuel blames racial bias and a "code of silence" for the city's "broken" police system.

The city's police force has come under new scrutiny in recent days, after two more people — a 19-year-old man and a 55-year-old woman — were shot and killed by police.
