The majority in yesterdays 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.
Here's Ginsburg's dissent. Could you point me to anything in it that would be cause for celebration?
