When is a person considered an adult? That’s at the heart of one proposal Massachusetts lawmakers are considering to reform the state’s criminal justice system. It would raise the age of most offenders are sent to juvenile court from 18 to 21. Massachusetts would be the first state in the country to do so.

New England Public Radio’s Kari Njiiri talked about this proposal with Springfield Republican political reporter Shira Schoenberg. She told Kari that this bill comes four years after lamakers raised the juvenile court age from 17 to 18, but advocates claim that didn’t go far enough.
