McDonald v. Chicago, 561 U. S. 742 (2010).
McDonald v. City of Chicago, case in which on June 28, 2010, the U.S. Supreme Court ruled (54) that the Second Amendment to the U.S. Constitution, which guarantees the right of the people to keep and bear Arms, applies to state and local governments as well as to the federal government.
District of Columbia v. Heller, 554 U. S. 570 (2008)
It is settled that the Second Amendment protects an
individual right to keep and bear arms that applies
against both the Federal Government and the States.
If Heller tells us anything, it is that firearms cannot be
categorically prohibited just because they are dangerous.
Just as the First Amendment protects modern forms of communications, and the Fourth Amendment applies to modern forms of search, the Second Amendment extends, prima facie, to all instruments that constitute bearable arms, even those that were not in existence at the time of the founding.
Heller defined the Arms covered by the Second Amendment to include any thing that a man wears for his defence, or takes into his hands, or useth in wrath to cast at or strike another.
Has either case helped the gun owners of CA, MA, CT, HI or soon to be VA from illegal infringements?
