Criminal fiction GNS model

I was reading a book about writing criminal fiction, (as in fiction detailing criminals, not rogue fictional characters...), and came across this in the foreword. If you can't see the G/N/S parallel, you're a lost cause.

"Should the writer present the whole affair as an intellectual exercise, a game of chess between the criminal and the law? Should he concentrate on the violent aspects of crime and pursuit, aiming to excite rather to puzzle his reader? Or should he look at the "why" of a crime rather than at the "who" or the "how", and seek, with careful scalpel, to dig down into the case-history of the criminal and his victim?"

The rest of the book is horribly out of date. For example, amongst the causes of crimes, it lists various drugs and their effects.
