Juvenile justice in the United States has predominantly been the province of the states and their localities. The first juvenile court in America was founded in 1899 in Cook County, Illinois, and, by 1925, all but two states had established juvenile court systems. The mission of these early juvenile courts was to rehabilitate young delinquents instead of just punishing them for their crimes; in practice, this led to marked procedural and substantive differences between the adult and juvenile court systems in the states, including a focus on the offenders and not the offences, and rehabilitation instead of punishment. This book concentrates on legislation, rights, funding and grant programs.
