RIP Joseph Wambaugh, 88, ex-cop and writer, who wrote brilliant police procedurals and true crime, including "The Onion Field."

I loved his books. His cops were sometimes heroic, sometimes bad and dirty, sometimes both at once. He wrote lovingly about them and about cold-blooded murderers.

He had a remarkable life, continuing to work as a policeman years after his writing career took off, quitting only when he became too famous for police work.

“I’m very interested in the concept of the sociopath, very interested, because my conscience has bothered me all my life,” he told The Los Angeles Times in 1989. “Talk about regrets – I have about 20 every day. I was educated in Catholic schools, and they did that to me. So I have to cope with a conscience all the time. And I’m interested in a creature who has none of that.”
