I think the author has been watching too many Dragnet reruns. Not that I mean to knock Dragnet -it was before my time, but I've watched reruns on and off for years- but although the stories were based on real incidents, the characters were fictional.
I have trouble with affirmative action myself, but the LAPD was infamous for racially-motivated brutality long before this article claims the whole mess started. I do not know exactly when, how, or why it began, but it is older than this article says. Affirmative action may have caused many problems, but this isn't one of them.
