Juvenile Justice System Metrics Interpretation
Despite the alarmingly high juvenile arrest and recidivism rates, especially among African American youth, the justice system's over-reliance on detention—often for non-violent status offenses—underscores that rather than addressing root causes like mental health and educational needs, many minors are caught in a cycle where justice is more punitive than rehabilitative.
