Those in Thursday's Town Hall meeting saw the video of Keita O'Neil being shot by a San Francisco police officer and expressed their horror.
Shock was quickly replaced by anger and even threats.
The community meeting was called after Friday's shooting on Fitzgerald Avenue. Police say O'Neil stole a white van owned by the California State Lottery.
Video shows police chasing O'Neil toward a housing development.
"Mr. O'Neil ran toward the marked SFPD vehicle while the van continued forward striking the fence," said San Francisco Police Chief William Scott.
The mother of Mario Woods, who was shot to death by San Francisco police two years ago, couldn't hold back.
"How can you do this," Gwen Woods said, fighting tears. "How can you?"
The officer has been placed on administrative leave.
Bayview's district captain is offering to hold weekly community meetings starting Monday.
