Amendment gives prosecutors rather than the courts the discretion to charge a juvenile alleged to have committed certain serious felonies as an adult or as a juvenile; makes fines and supervised release available for adjudicated delinquents in addition to probation and detention; provides that the records of juvenile proceedings are public records to the same extent that the records of adult criminal proceedings will be public; increases the penalty that may be imposed on juveniles who possess a firearm; and limits the distribution of information concerning explosives.
