The first part of the study summarizes recent crime trends observable in statistical data, particularly those for 1981, and recidivism is analyzed through the use of computerized criminal records. Offense statistics are broken down by penal code offenses and special law offenses (traffic violations included in the latter category). In examining trends affecting various crimes, attention is given to crimes committed by violent gangster groups, public officials, extremist groups, foreigners, and nationals. Pollution and traffic offenses are also considered. Special types of crimes noted to be problematic in recent years are bank robbery, stranger-to-stranger crime in public places, murder and arson for insurance money, and computer crimes. Part two of the study describes the processing of offenders in the phases of prosecution, adjudication, correctional administration, and rehabilitation (probation, parole, and aftercare). Part three covers trends in juvenile criminality and delinquency and modes of treating juvenile offenders. The concluding part addresses the trend in drug offenses, which are on the increase, and countermeasures which have been taken. The countermeasures identified are the strengthening of control agencies, increased sanctions, and a nationwide educational campaign to eradicate stimulant drug abuse. Drug offenses are also reviewed for the United States, the United Kingdom, West Germany, Thailand, and Hong Kong. Tabular and graphic data are provided throughout the report.
