Most if not all law enforcement in south Orange County, including my city of Mission Viejo, is contracted to the Orange County Sheriff Dept. Older cities in the north part of the county, inclufing Anaheim, Fullerton, Santa Ana, Huntington Beach, Buena Park, etc have a local police department.
I assume that is why the Mission Viejo city council passed a resolution instead of an ordinance. MV can’t do anything effectively otherwise.
