Many people in the criminal justice reform movement believe people should not be held fully responsible for their criminal actions, and it is continuing to push that idea forward in several states.

The Massachusetts Supreme Judicial Court ruled on Thursday that anyone under the age of 21 cannot be sentenced to life in prison without parole. This was in response to the case of Sheldon Mattis, a gang member who, along with Nyasani Watt, gunned down a 16-year-old in cold blood. They had also tried to kill a 14-year-old in that same shooting.
