Castle Law States MA?

[bashiosan]

I have seen two different TV news versions of the 'Oklahoma' incident with the teenage mother of baby who shot and killed armed intruder. She called '911' and asked for advise or permission to shoot if intruder entered here home. He broke in and she shot him - dead (not sad). Story stated that her husband died of cancer on Christmas. (sad)
Here is my question. Two different TV news stations showed US states that have 'Castle Law'. In one video, MA was identified as having the 'Castle Law', the other did not.
Can anyone provide clarification or website to states with Castle Law in effect?
Thanks

Section 8A. In the prosecution of a person who is an occupant of a dwelling charged with killing or injuring one who was unlawfully in said dwelling, it shall be a defense that the occupant was in his dwelling at the time of the offense and that he acted in the reasonable belief that the person unlawfully in said dwelling was about to inflict great bodily injury or death upon said occupant or upon another person lawfully in said dwelling, and that said occupant used reasonable means to defend himself or such other person lawfully in said dwelling. There shall be no duty on said occupant to retreat from such person unlawfully in said dwelling.
General Laws: CHAPTER 278, Section 8A

So...yes, MA allows the Castle Doctrine, according to this.
