What’s your obsession with Orange County hatred? The county doesn’t hire cops — individual towns do, and it varies by town. Some may hire thugs and incompetents, others may vet their applicants better.
And I’m sure that there are many places with brutal cops outside of Orange County, CA. BTW – I don’t think the problem is anything new in California. LAPD had a reputation for nastiness and corruption likely well before you were born — 20s through 60s.
I know a few people who grew up in various parts of OC — they seem like decent people to me, not trashy or whatever you think of them.
