Oakland officials are acknowledging that Mayor Jean Quan’s “one-hundred block” crime-fighting plan miscalculated where most violent crime in the city takes place.

Quan has been saying that 90 percent of the crime in Oakland takes place in 100 blocks, and that the city is focusing police and other city services on those blocks.

On Wednesday her chief of staff disavowed those numbers. “I don’t know where the 90 percent number came from,” said Campbell Washington, who joined Quan’s staff after the release of the 100 Blocks plan, according to the Oakland Tribune.

Earlier this month, the Urban Strategies Council analyzed crime data, and reported that violence was much more spread out geographically.

In an interview with KQED’s Andrew Stelzer Thursday, Junious William, the group’s CEO, said Quan’s crime-fighting strategy includes many praise-worthy aspects which should now be adjusted. But he said the larger lesson is that data about the Mayor’s plan and its effectiveness should have been made public.

“It’s really I think a safeguard for all of us to have the data openly available and the ability for people to look at it and drill down,” he said. “It’s really a sort of self-correcting mechanism.”

Quan’s office says the mayor didn’t know her data was incorrect until last week.

    They never disavowed that crime (actually violence) was taking place in those neighborhoods but that the area is larger than that and that the concentration which has always been in those neighborhoods is not the entire area where violence occurs but a very significant percentage does occur there. That’s a whole different argument than the one you just made.
