Probation was the most serious verdict in one-third of teen crime in the U.S. In 2007, 1.7 million delinquency cases were handled by courts with juvenile jurisdiction. This has increased 34% over the past three decades. Nearly 60% of the cases were ordered by the court while the remainder agreed to some form of voluntary probation. This is according to a report by the Office of Juvenile Justice and Delinquency Prevention.
