Young offender
Young persons who, in many states, are treated differently than adult criminals and are tried in special youth courts. In Canada, for example, criminal suspects between 12 and 17 inclusively are processed under the Young Offenders Act, which includes several provisions which reflect the rehabilitative nature of the legislation.
