This book is an attempt to bring into focus the significance of the term `Social Defence` and to dispel some prevalent misconceptions arising basically out of ignorance or a lack of information. In fact, the idea of social defence is not new. It retains its origin in the dim past. In course of time, it has acquired a new dimension. It encompasses within its ambit all the components of the criminal justice system like judiciary, police, prison and other institutional and non-institutional services for treatment, training and ultimate rehabilitation and reassimilation of offenders into society. This book contains seven chapters with nineteen articles lucidly delineating different areas of social defence. The author has a long personal experience and practical insight into the problems in implementing the social defence programmes in the country. His discussions on various aspects of the subject are deeply penetrating, thought-provoking and interesting. The importance of this book lies in the fact that the contents are mainly based on indigenous material. The students of criminology and correctional administration, social scientists, social workers, psychologists and those associated with the criminal justice system will be immensely benefited by reading this book.
