If the county were to stand up a department that handled parking enforcement, the work could be done by non-sworn employees who would be paid less but probably in the role longer because there would be a career path that led to managerial roles.
An upside for law enforcement is that officers would be able to do more of the work they want to do than the work they don't want to do.
The bowdlerized version of "defund the police" can very easily get in the way of a serious conversation about "what's the best way to spend public funds." There's a website
Transparent California that allows one to look at how much public employees earn. And budget information for municipalities and counties are readily available, as are job descriptions.
Officers are not paid as much as they should and their job descriptions include tasks that may not be the best use of their time. If boxes were moved around on organizational charts and money were reallocated, you could get more bang for the buck without necessarily firing anyone or cutting anyone's pay. (You get rid of a couple of bad apple officers, fill their roles with officers who were previously doing parking.)
