Here's what I was referring to. "
The Choirboys, a novel, is a controversial 1975 work of fiction written by Los Angeles Police Department officer-turned-novelist
Joseph Wambaugh."
One of the lead character's in this book was Rosco Rules. I think, as if anyone cares what I think,

that it is "controversial" because it includes a lot of scenarios that are everyday real to police that the majority of citizens never even dream about!
He wrote a number of darn good police story based books.
