According to Judge Robert H. Bork and other authoritarians, the founders intended the 2nd Amendment to cover a States right to bear arms. According to the plain English of the various Founders and that found in the Bill of Rights itself, the Amendment was written to cover individual rights.
Their non-ruling simply means that less than 4 judges thought the matter important enough to hear the case. IOWs they're satisfied with the status quo.
Right, and someday it will be argued; “The founders intended the 1st Amendment to cover a State's right to free exercise of religion, freedom of speech and press the right of State sponsored organizations to peaceably assemble and to petition the government for a redress of grievances.”
