The lines between lawman and outlaw blur. In Good Guy, Bad Guy, Lavigne investigates the rise of drug‑fueled organized crime, from the streets of North America to the jungles of South America. He explores how narcotics trafficking transformed criminal empires, corrupted institutions, and challenged law enforcement. The book paints a vivid picture of a world where yesterday’s “bad guys” adapt faster than the “good guys” sworn to stop them.
