Selected Case Law
Commonwealth v. Fettes, 64 Mass.App.Ct. 917 (2005). A dog can be a dangerous weapon. "A dangerous weapon is 'any instrument or instrumentality so constructed or so used as to be likely to produce death or great bodily harm.' Commonwealth v. Farrell, 322 Mass. 606, 614-615 (1948). See also Anderson, Wharton's Criminal Law and Procedure, § 361. There can be little doubt that a dog . . . used for the purpose of intimidation or attack falls within this definition." Commonwealth v. Tarrant, 2 Mass. App. Ct. 483, 486 (1974)."
Commonwealth v. Runyan, 456 Mass. 230 (2010). Trigger locks or locked containers can be required. The Second Amendment is not incorporated under the Fourteenth Amendment's guarantee of substantive due process and therefore does not apply to the States. Further, the General Laws c. 140, § 131L (a) can be distinguished from the law ruled unconstitutional in Heller, because "an individual with a valid firearms identification card issued under G. L. c. 140, § 129C, is not obliged to secure or render inoperable a firearm while the individual carries it or while it remains otherwise under the individual's control...; the statute therefore does not make it impossible for those persons licensed to possess firearms to rely on them for lawful self-defense."
District of Columbia v. Heller, 554 US 570, 128 S.Ct. 2783 (June 26, 2008). "The Second Amendment protects an individual right to possess a firearm unconnected with service in a militia, and to use that arm for traditionally lawful purposes, such as self-defense within the home."
McDonald v. City of Chicago, __ US __, 130 S.Ct. 3020 (2010). In clearly stating that "the Due Process Clause of the Fourteenth Amendment makes the Second Amendment right binding on the States," the court also reiterated its statement from Heller that "the right to keep and bear arms is not 'a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose.'”
