This book offers a holistic and broad discussion of vulnerable victims, what constitutes victimisation, and how different groups within society are supported through, impacted by, and protected by different agencies and actors within the criminal justice system, society, voluntary organisations, and research. The victims covered in this book include children, domestic abuse survivors, to those becoming victimised through the state, or those not recognised as having "victimhood" status. This book includes chapters and discussions from both practitioners and academics. The authors reflect on practice and policy implications, empirical research, and policy guidance. It includes suggestions for both practice and research for working with vulnerable victims, marginalised groups, and difficult-to-access communities.
