If I'm wrong, I'll say so. Just point to the law that makes that clear.
And second...and far more important...your belief that *laws* mean a gosh darn thing to Marsha Coakley or any of this great Commonwealth's 13 District Attorneys betrays an unfortunate naivete regarding how things are done here.
Call it naivete if you like. I rather like to call it tenacity.
They've never met me in a court of law. And I have the law on my side. Nay...I shall not go quietly into that dark night.
MGL Part IV, Title II, Chapter 278, Section 8a:
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.
I know of cases in the Commonwealth which would give you the impression that we have DAs who seem to have an agenda...like the man who took a baseball bat to a perp out in the street in front of his house as his tool box was being swiped. But if you look at them carefully, these people did not have their lives in danger.
