CHICAGO — A video released Friday shows a 2012 police shooting in Chicago Lawn where officers shoot and stun a hulking, shirtless man who attacked a CTA bus driver, passengers and passers-by.

The Independent Police Review Authority released video of the police shooting of Ismael Jamison, who survived the shooting.

The incident occurred the afternoon of Nov. 22, 2012, at 62nd Street and California Avenue, according to authorities. The shooting is seen in the video below. An officer appears to shoot at Jamison after he started charging at him.

The following video shows Jamison walking around the 6200 block of South California Avenue shirtless and at one point pulling at a pedestrian.

"The Offender battered the elderly CTA bus driver and other citizens on the street with his hands and fists," according to a police incident report. "The offender then attempted to commit a battery to the responding uniformed CPD officer in an attempt to defeat the arrest. The offender was subsequently shot by that officer who was acting in self defense."

The officer who shot Jamison told investigators that he was flagged down on California Avenue by someone who said there was a man on the bus beating people up.

Jamison got off the bus and walked toward the officer, who told him to get back. Jamison later lunged toward the officer, who then fired several times.

Jamison was charged with felony aggravated battery and taken to a hospital.

The video and details in the case were released as part of a massive data dump by IPRA on Friday, showing documents and videos in more than 100 Chicago police misconduct cases.

The release comes after Mayor Rahm Emanuel's appointed Police Accountability Task Force called on the Chicago Police Department to acknowledge racism and fight the "code of silence" that keeps officers from being held accountable.

That task force also called for videos to be more readily released to the public, within 60-90 days.

The massive release of videos includes many open cases, some of which are the subjects of lawsuits. At a news conference Friday, IPRA boss Sharon Fairley stressed that videos do not paint a complete picture of what happened in each incident, and many lack context.

“It's really important for you to keep in mind that these materials may not convey all of the facts and considerations that are relevant [to an officer's conduct," she said.
