Speaking at a press conference Tuesday, he said in a week the city has seen 20 shootings, five of them homicides, and so far this year, there have been 14 homicides, two more than at this time last year.
Jordan blamed much of the violence on disputes between two rival groups in West Oakland and two other groups in East Oakland.
Most of the killings are committed by people who are involved in other types of illegal activity, he said.
“Quite simply, that is unacceptable. I want to make Oakland one of the safer large cities in California,” he said. “The department cannot do it alone.”
