SAN JOSE -- City leaders Tuesday shot down a proposed ballot measure that would have asked voters to guarantee a minimum share of the budget for the police force, arguing it would decimate other public services.

Ten of the 11 City Council members wound up against placing the measure on the June 3 ballot. Mayor Chuck Reed, leading the charge against it, said the measure would be "a horrible mistake" that would force the city to close libraries, community centers and fire stations.

Councilman and mayoral hopeful Pierluigi Oliverio last month proposed the initiative to increase police department spending from 30 percent of the city budget to 40 percent. He argued the most important city function should be funded accordingly, especially as arrests have dropped and crime has increased.

But critics including the police union had written off the Willow Glen councilman's plan as a political stunt. City budget officials said they would have to cut all other departments by about 30 percent to make the new spending plan work.

Councilman Ash Kalra joked that Oliverio had "brought the council together" -- against the plan, even when Oliverio offered to drop his proposed police funding minimum to 35 percent during Tuesday's meeting.

The defeat is a blow to Oliverio's mayoral credentials as polls suggest public safety will be the top concern of voters. Vice Mayor Madison Nguyen, council members Rose Herrera and Sam Liccardo, and Santa Clara County Supervisor Dave Cortese are also largely running on public safety platforms in the race to replace the termed-out mayor.
