The document discusses social defence, which refers to protecting society from crime and deviance through both prevention and rehabilitation efforts. Major areas of social defence include preventing juvenile delinquency, beggary, alcoholism and drug dependence, and supporting prisoner welfare. The Ministry of Home Affairs oversees police and criminal legislation while the Ministry of Welfare addresses programs for at-risk youth, probation, prisons, suppression of human trafficking, and rehabilitation. The National Institute of Social Defence was established to review and develop policies around social defence areas like juvenile justice, prisons, probation, and addiction treatment.
