Zev Yaroslavsky, director of the Los Angeles Initiative at UCLA Luskin, joined KPCC’s “AirTalk” to discuss tensions between the L.A. County Board of Supervisors and Sheriff Alex Villanueva. The supervisors have voted 3-2 to explore options to impeach or reduce the responsibilities of Villanueva. Yaroslavsky, a former L.A. County supervisor, said there is always some tension between the sheriff and the supervisors, but they’ve historically been able to work together to adhere to their constitutional responsibilities. However, he said, Villanueva has violated agreements on constitutional policing issues, including excessive use of force. Yaroslavsky agreed that it is important to raise the idea of changing the way that sheriffs are chosen but said he doesn’t think voters would approve the measure. “The resources and energies that would have to be brought to bear on a constitutional amendment or charter change should be brought to bear on removing him from office in the regularly scheduled election,” he said.
