More than a dozen videos released by the Cook County Sheriff's Office this week show the commotion after Roberson was shot by a Midlothian, Illinois, police officer in front of Manny's Blue Room Lounge in November.
"Your man shot my man, the police shot him safely, that's what happened," a distraught security guard said at the bar to the police.
The videos, shot by police cameras, body cameras and cell phones, show only the consequences of the shooting, not the time when Roberson was shot to death. It is not clear if any shooting footage exists.
The 26-year-old security guard was on duty at the bar in Robbins, Ill., When a gunman started firing. Witnesses said Roberson stopped the shooter and pinned him to the ground. But shortly thereafter, the Midlothian officer shot and killed Roberson.
While witnesses said the guard was wearing clothes that clearly identified him as security, the Illinois State Police, the lead agency for the investigation, said Roberson was wearing "plain black unmarked clothing promptly identifying him as a security guard. safety".
In a statement, Cara Smith, policy director for the Cook County Sheriff's Office, said the agency released the videos in response to a request from the Freedom of Information Act and "in the interest of transparency."
Smith also declined to comment on the criminal investigation, saying the detectives "continue to work diligently to investigate the initial gunfire at Manny's in Robbins."
Several videos recorded outside the club show police and paramedics caring for Roberson and later driving him away from the parking lot on a stretcher.
A man dressed in a black vest, who said he was also a security guard, can be seen in a couple of videos talking to an officer.
"Someone opened the side door. He came in and fired like (inaudible) five shots," he says before telling the officer how Roberson was holding a suspected sniper on the ground.
"Everything was clear, everything was down, everything was down, bruh," he added.
The man describes the moment when the Midlothian officer opened fire.
"I'm telling him:" He's working with us. Cool yourself. He's working with us. " He shot him four or five times after we told him he's with us, "he said.
He continues, "I want his name. I want his badge number."
Illinois State Police described events differently in the days after the incident.
"According to witness statements, the Midlothian officer gave the armed man several verbal commands to drop the weapon and reach the ground before finally unloading his weapon and attacking" the security guard, police said in a statement.
Midlothian police chief Daniel Delaney described the shooting as "the equivalent of a friendly fire incident" blue-on-blue. ""
