"We know that our child protection system is in crisis," Supervisor Gloria Molina said. "We can’t wait any longer. We must act now."
Supervisor Mark Ridley-Thomas said, "This is worth the effort because I know that the status quo is untenable and costly — morally and financially."

"I think it's worth a shot," he said.
