SACRAMENTO -- Tuesday's city council meeting in Sacramento started about 15 minutes late and you could hear the reason why in Mayor Kevin Johnson's voice.
"Watching that video was very difficult for all of us..." he said, as council member comment was moved close to the top of the agenda.
He was reacting to watching Joseph Mann lose his life at the hands of his city's officers July 11.
The closed session council screening and briefing of the incident was done by the police department as part of an unprecedented video and audio tape release -- shared with the press two hours earlier -- all before the investigation of the case is complete.
With the Mann family filing of a federal civil rights lawsuit and the public demanding the video, Chief Sam Somers said he needed to take steps he never had before.
"I think this is a very important news conference, probably one of the most important ones I've had in my career," he said.
"I also want to wish condolences to the Mann family and the officers involved in this," he said.
The newly released tapes show it was just 11 minutes from the beginning of the end of Mann's life to when the 18 shots that killed him were fired.
Fourteen of them hit the 51-year-old former Department of Corrections employee.
Here's some of what the second 911-caller had to say:
"There's a man outside my apartment with a gun, and there's children all around (dispather: wh-) and he's mentally ill."
Responding to reports of a man waving a knife and gun, police video shows officers trying to get Mann to stop walking through the neighborhood.
Later you can see him throwing something at a patrol car.
The last thing he does before being killed is run across Del Paso Boulevard, away from pursuing officers.
The two who shot had just pulled up.
"There was no basis in fact for them to use deadly force and the video shows that pretty clearly. He was not charging them," Mann family attorney John Burris told FOX40 by phone from his office in Oakland.
At city council, there were "boos" in the audience as the mayor discussed what had happened to date in Mann's case.
"We -- now more than ever -- really need to come together as a community," he said as the meeting moved on.
Then he announced a new council sub-committee to look at creating new city protocols for informing and allowing council to weigh-in after an incident like Mann's.
It will also study if police have enough non-lethal options available to them and survey the level of satisfaction Sacramentans have with their police force.
On what many see as a black and white ... grey area in policing ... only the four black members of the council chose to comment on the Mann tapes or plans for new city policies in the wake of their release.
Despite the initial reports of Mann wielding a gun, officers never found one on him or one he discarded.
The mayor and Somers had hoped to show his family the videos released Tuesday before they were made public but weren't able to work that out.
The new subcommittee wants to create a city protocol for responding to families in these situations.
While Joseph Mann's relatives did not want to comment about the video release on Tuesday, their attorney announced late in the day that they would hold a press conference Wednesday morning.
