How one man’s life is reshaping criminological thinking

Through William ‘Billy’ Mahaffey's story, Bringing Criminological Theory to Life demonstrates why people engage in and leave crime behind.

鶹ý’s will officially launch next week, a powerful new book set to redefine how criminology is taught and understood. The book offers a fresh take on academic theory, told through the compelling story of William ‘Billy’ Mahaffey, a former soldier, prisoner, and now, community role model.  

Through Bringing Criminological Theory to Life, we’re taken on a journey that spans a troubled childhood, through addiction and incarceration, military service, to education, athletic achievement, and community leadership. A powerful mix of expert insight and real-life experience conveys the challenges of crime, the impact of punishment, and the potential for change.  

Each chapter explores a key turning point in Billy’s life to interrogate criminological concepts, including the long-term impact of childhood experiences, the military-to-prison pipeline, and the role of education, sport, and networks supporting journeys out of crime and identity transformation.  

“This book is a new kind of criminology,” said , Senior Lecturer in Criminology at 鶹ý. “It breaks down barriers between academic theory and human experience, and makes the case for a more compassionate, context-aware understanding of crime and change.” 

Hosted by the at 鶹ý, the launch event will continue these conversations, featuring contributions from Billy himself, co-editors Dr Emily Turner, , (University of 鶹ý) and (University of Liverpool), as well as chapter authors from leading institutions across the UK.  

Inspired by teaching methods that embed real-world experience into theory, this book is a call to rethink traditional approaches to education and criminal justice. Billy, now a father of two and active in his community, has rebuilt his life after years of instability, addiction, and imprisonment. His story is one of persistence and personal accountability, offering a powerful reminder that change is possible, even in the face of overwhelming adversity. 

“I never imagined that my life story would be used in this way,” said Billy. 

Some of it is painful to relive, but if sharing it helps someone better understand these issues, or feel less alone, then it’s worth every moment.
