Query: in-depth knowledge of a man who worked with rodney king

I was generally glued to this book, although the technicalities of the workings of the LAPD left me lost or vacant, at times. I had the rare occasion to work with the author for six weeks during an Army public relations tour in Nicaragua, and his insights into life in the LAPD and life, as a cop, in general, furthered to set the stage for the book. Tom Owens is a well-read, knowledgeable man in workings of life as a private dectective and cop. I wouldn't want him investigating me!
