CHICAGO -- Video released Thursday shows a 2013 fatal shooting of a 17-year-old black carjacking suspect by a white Chicago police officer, although footage of the moment the teenager is shot doesn't answer clearly whether the teen turned toward the pursuing officers or was holding anything, as the officer who opened fire has said.

A federal judge lifted a protective order on the video of Cedrick Chatman's last seconds after the city -- in a surprise about-face -- dropped its longstanding opposition to making it public. Since the November release of video in a separate case showing a white officer shooting a black teenager 16 times in 2014, city leaders and the police department have come under scrutiny over cases of alleged misconduct amid calls for greater transparency.

The video released Thursday was shot by several surveillance cameras and from various angles. It captured at least parts of the Jan. 7, 2013, shooting in a South Shore neighborhood during daylight hours.

Overhead video from a blue-light police camera city attorneys consider to be the primary footage shows Chatman bolt out of a car and across a street with officer Lou Toth on his heels. Chatman scoots through parked cars and then toward a nearby intersection.

Less than 10 seconds elapses from the time Chatman jumps out of the car to the fatal shots.

Toth's partner, officer Kevin Fry, can be seen trailing farther back, aiming his gun at Chatman from a crosswalk and firing as the teen begins rounding the corner in front of a bodega. One video from a camera that pans back and forth is grainy and doesn't show Chatman fall; another is clearer and shows Chatman fall, but it is taken from farther away and doesn't show definitively whether Chatman turned.

Fry said in a 2014 deposition he opened fire out of fear for his own life and his partner's after Chatman "makes a slight turn" holding an object.

"It was a small, black object, which I believed to be a handgun," Fry said.

Investigators later said the object was an iPhone box.

Chatman's mother filed a wrongful-death suit against the city and the two police officers. Her attorney, Brian Coffman, said the teen never turned toward the officers and posed no threat.

Questions about the Chatman video follow the Nov. 24 release of another video showing white officer Jason Van Dyke fatally shooting black teenager Laquan McDonald 16 times in 2014.

The city fought its release for more than a year, making it public only after a state court ordered it to do so. The video and the delay in releasing it led to protests, calls for Mayor Rahm Emanuel to resign and a federal civil-rights investigation of the Chicago Police Department.

In his deposition, Toth said the officers had stopped the car Chatman was in after a radio report of a carjacking in progress, saying both officers drew their weapons immediately because they suspected the car of involvement in a serious crime.

Toth describes nearing the car before Chatman fled, shouting, "Police! Police! Put your hands up."

Chatman's family had asked the video be made public, arguing it would counter the city's narrative Chatman posed a danger to police.

City attorneys until Wednesday fought to keep it under seal on the grounds its release could taint any jury pool, should the civil case go to trial.

They said in a Wednesday court filing the city was dropping its opposition in an effort to be more transparent while it waits for a recently created special task force to review policies regarding the release of videos showing disputed police shootings.

City attorney Jonathan Green told U.S. District Judge Robert Gettleman on Thursday the legal basis for withholding videos remains sound. But he also said calculations about when to release footage have changed in the era of cellphone and security cameras.

"The city recognizes ... that we are in a new world," he said. "We are making a policy change on behalf of the people of Chicago."

After Green spoke, Gettleman criticized the city attorneys for suddenly changing their position on the video's release on policy, not legal grounds after spending weeks trying to prevent it.

"I went to a lot of trouble to decide this issue, and then I get this motion last night (Wednesday) saying that this is the Age of Enlightenment with the city and we're going to be transparent," Gettleman said. "I think it's irresponsible."

The Independent Police Review Authority, which investigates police shootings, cleared the officer who shot Chatman of any wrongdoing. But court filings allege the agency cleared the officer only after an investigator who opposed that finding, Lorenzo Davis, was fired. Davis has filed a separate lawsuit about his dismissal.

Coffman said Chatman's mother, whom he represents, wanted the public at large to see the video. But he said she wouldn't watch it.
