Whoever is stating that there are no such laws
is misinformed. I could make a snotty remark about tupperware shooters, but will bite my tongue and refrain from the cheap (plastic) shot.
From the Massachusetts General Laws:
G.L.c. 278, § 8A. Killing or injuring a person unlawfully in a dwelling; defense.
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.
G.L.c. 231, § 85U. Death or injury to unlawful dwelling occupants; liability of lawful occupants.
Section 85U. No person who is a lawful occupant of a dwelling shall be liable in an action for damages for death or injuries to an unlawful occupant of said dwelling resulting from the acts of said lawful occupant; provided, however, that said lawful occupant was in the dwelling at the time of the occurrence and that he acted in the reasonable belief that the person unlawfully in said lawful dwelling was about to inflict great bodily injury or death upon said occupant or upon another person lawfully in said dwelling, and that said lawful occupant used reasonable means to defend himself or such other person lawfully in said dwelling. There shall not be a duty on said occupant to retreat from such person unlawfully in said dwelling.
Section 8A provides an affirmative defense in a criminal prosecution; Section 85U is the BAR to civil claims the Glock yakker claims does not exist.
