The need for nursing to focus its attention on particularly vulnerable groups within our society is more urgent and vital than ever. A decent society should be measured by how well it cares for people who often do not have a voice. This is particularly true of people with health and nursing care needs who come into contact with our justice system. This book identifies the challenges facing nurses in the criminal justice services. Importantly, it also pinpoints many of the practical solutions and opportunities that high-quality nursing care and delivery can offer. In the past decade there have been extensive changes as well as progress in the way our health and justice systems work together. It is not at all unusual to see service innovation, new creative partnerships and stronger frontline practice delivered by nurses in prisons, in police custody, in our courts, probation services and immigration centres. I am particularly pleased to recommend this book to you as an important reminder that nursing can and does operate well in many settings and services and provides a much-needed voice for people who otherwise remain unnoticed and whose citizenship is denied. It is increasingly apparent that good health in the justice system also means good public health and I am delighted to see that, through nursing and partnerships, both can be achieved.
