Brain research has proven that children are developmentally different from adults and that their brains, not just their bodies, are not yet fully mature. The U.S. Supreme Court has ruled on multiple occasions that this difference must be acknowledged and considered in the context of sentencing. This requires that we hold young people convicted of serious crimes accountable for the harm they have caused in ways that acknowledge their unique status as children and focus on their capacity for rehabilitation and reintegration into society. Therefore, we believe that youth under the age of 18 should never be sentenced to prison for the rest of their lives without hope of release.
