For many officers, the stories they collect on the job remain within squad room walls. San Francisco Police Sergeant Adam Plantinga has turned his into the foundation of a second career, using two decades in patrol, investigations and specialized units to fuel both nonfiction accounts and gritty crime novels.

In this episode of the Policing Matters podcast, host Jim Dudley talks with Plantinga about his journey from Milwaukee patrol officer to SFPD sergeant, his acclaimed nonfiction titles “400 Things Cops Know” and “Police Craft,” and his crime series featuring a former Detroit officer. Plantinga explains how real-world policing — from bizarre street encounters to high-stakes cases — shapes his stories, why he moved from nonfiction to fiction, and the strategies he uses to carve out writing time alongside a demanding law enforcement career.
