True crime stories dominate our screens and feeds. But John J. Lennon wants us to question how much truth they're telling – and whose. He reflects on those ideas in his book The Tragedy of True Crime: Four Guilty Men and the Stories That Define Us. And one of the guilty men he writes about is himself. Lennon is serving a 28-years-to-life sentence in New York state for murder, drug sales and gun possession, and has become a professional writer while in prison. He joins Piya Chattopadhyay to talk about his approach to telling crime stories, and the search for meaning, growth and identity inside the system.
