which answers the question of what Scalia thought the founders meant and what Scalia thought was permitted under the English Bill of Rights (1689).
It doesn't address what the founders actually thought, nor how they'd respond to modern weapons in the hands of mass shooters.
These were educated men. They had an idea about how technology could improve and, more specifically, that technological development would first be applied to war.
I’m not trying to start an argument on the legitimacy or lack thereof of decisions; I’m pointing out that if you want to play the originalist game, there are plenty of other examples that you may not like.
America had no standing army, and many of the founders did not want one. Hence, the need for a militia.
It’s a prefatory clause and an operative clause. The first explains the purpose, the second gives the rule. So you can certainly argue that the rule must be considered in the context of the purpose.
But that still doesn’t get you where you’re going. Because personal firearms ownership certainly facilitates raising a militia if you need one.
I wonder if that means the lack in the US of official citizen militias dependent on private firearm ownership could be considered unconstitutional.
IIRC, the National Guard is reckoned to be the militia, but that seems a little like BS to me. It seems pretty much to be a de-facto component of the federal military, complete with rotations to fight foreign wars, etc.
