Court Rejects Strict Gun Law as Unconstitutional
The majority in yesterday’s decision pointed to a 1998 dissent in which “at least three current members (and one former member) of the Supreme Court have read ‘bear arms’ in the Second Amendment to have meaning beyond mere soldiering.” They were former Chief Justice William H. Rehnquist, who died in 2005, and Justices Ruth Bader Ginsburg, Antonin Scalia and David H. Souter.
Read the decision. It's rather comprehensive and airtight, IMHO.
...take the musket from the shoulders of our brave black soldiers, deny them the constitutional right to keep and bear arms...
