Adolescence, Brain Development and Legal Culpability

“Should the State of Massachusetts raise the age of juvenile justice jurisdiction to age 20. making 21 the age at which a person must be tried as an adult? Why or why not?”
Your essay must use these three sources: 1) Elizabeth Cauffman, -How Developmental Science Influences Juvenile Justice Reform,’ 2) the Roper decision of the Supreme Court, and 3) Selen Siringil Perker, “Emerging Adults: A distinct population that calls for an age-appropriate approach by the justice system.” You may use the other articles as well, but you are not required to do so.
In developing your argument, incorporate ideas that support your position as well as ideas that disagree with your position. Your essay must quote and/or paraphrase and work directly with material from all four readings in this reading set. In addition, define and employ key terms that seem to be central to the arguments of your sources and, therefore, to your argument as well. Primary among these key terms is Culpability. Additional key terms: developmental science; psychosocial maturity; future orientation; executive function; desistance; penal proportionality; categorical; prophylactic; emerging adults.
