Society's attitude towards those who commit crime is undergoing a fundamental change. Interest in criminals has changed from the moral and legal to the psychological and sociological aspects, with the result that the criminal to-day has acquired a new importance. In the old days the community set out to punish the criminal and did so with considerable severity. The Law still continues to keep as its first consideration the protection of the community, and the claims of society are considered greater than those of the individual. Nevertheless, intensive study of individual offenders is essential if we hope to be able to advise society as to the best methods of dealing with those members who will not or cannot obey its rules.
