Its intention is to enable the reader to understand the basic thoughts and fundamental facts and problems of criminology without getting bogged down in statistics and temporary theories. The book is divided into two sections, the nature of crime and the control of crime. The former covers such areas as the concept and extent of crime and the development of the crime problem as we know it today. The book includes complete discussions on the topics of forms of criminal expression and sociologic orientations. There is a chapter on collective criminology and political crimes. The second section of the work includes coverage of punishments, the death penalty, and imprisonment. The final chapter describes the status of flexible institutions of sentencing and punishment. A twelve-page list of suggested readings and an alphabetical index are appended. (Author abstract)
