1. Moffitt focuses on the importance of the developmental histories of different types of delinquents. Thinking about her work and what it says about the nature of delinquency, answer the following questions:

(a) What are the difficulties in distinguishing between her two groups and how is this tied into what the juvenile justice system knows when it encounters delinquent youth?

(b) Are there other important implications for juvenile justice policy and practice embedded in our understanding of her taxonomy? For example, what role can be played by risk assessment (as relates to the developmental taxonomy) in the juvenile justice system?
