The British criminologist Julian V. Roberts published Criminal Justice: A Very Short Introduction in 2015. The book is focused on the systems that are based on British common law such as the United States, Canada, or Australia. Roberts writes “Even within the common law world, criminal justice looks very different when comparing, for example, California and Cardiff '' in Wales (Roberts xv). I read the book on my Kindle. The book has illustrations. The book has a section on “further readings” (Roberts 130-132) and an index. The book has an appendix. The book has an appendix of a case where a mother who murdered her son in England or Wales after her son was injured in a car accident. The case had more details than that. Roberts is curious whether the reader agrees with the decision of the court in England or Wales to sentence her to life in prison. In England and Wales, life in prison is a mandatory sentence for murder (Roberts 80-81). Roberts is a personality in the book. As Roberts writes “scholarship on criminal justice is infused with ideology and opinion” (Roberts xv). I found more or less appreciated his opinion throughout his book. I thought Roberts’ introduction to Criminal Justice was a well-done introduction to the field.
