Professor Peter Nwankwo argues based on this textbook volume I, that the world has been turned into a global village, and that we have no reason(s) to ignore the awareness of what is going on in other countries of the world. This textbook "Criminology and criminal Justice System of the world: A comparative perspective" is a unique text, not because of its title, but because it contains what will ever be needed for the undergraduate and graduate students in the field of Criminology and Criminal Justice, especially those taking a course in Comparative Criminal Justice. The text is prodigious and profusely descriptive, explored, and explained by researching the police, the court systems, corrections or prisons, including Juvenile Justice Systems and Crime Statistics in the following countries: United States of America, china, Saudi Arabia, Japan, The Netherlands, Bulgaria, Haiti, Botswana, Philippines, Uganda, and Israel. It is worthy to note that the United States of America had too much information, so it was necessary to split it into two chapters i.e. chapter one, and chapter two. Additionally, The Netherlands was also split into two chapters thus: Chapters 6 & 7: The overall Chapters in this Volume I are thirteen.
VOLUME II Volume two of this text contains twenty four chapters and over 24 countries were researched and included as follows, and will be published in a few in a few months .The countries are: Nigeria, Norway, Northern Ireland, England and Wales, Estonia, Ethiopia, Egypt, South America, Mauritania, Jamaica, Iraq, Dominican Republic, Turkey, South Africa, Russia, Kenya, Romania, Congo, Germany, France, Cameroon, Ghana and Denmark. No matter the adversities of the readers and purchasers, I do strongly advice that you order these two volumes together, when the later would be available on the internet or through the publishers.
