I supported the emergence of that new understanding and the Supreme Court made it the law of the land in the Helen Mcdonald decisions. In 2008 and 2010. Of that pair of decisions demolishes the slippery slope theory of those who oppose basically all firearms regulation on the view that once we permit any new firearms regulation at all, we will be inviting the government stepbystep to come ever closer to disarm the people. Leaving only the police and military with firearms. With heller and mcdonald on the books, Supreme Court in its own words took certain policy choices off the table. Thereby cleared the path a reasonable regulations to be enacted without fear that those policy choices would either open the door to unlimited government control, or be imperiled by exaggerated interpretation of the Second Amendment. As Justice Alito put in mcdonald, theres no longer any basis for such doomsday proclamations. Justice scalia speaking for the court and heller said at the end of his opinion.
