And how does the Militia Act treat "well regulated"?
C&P me an example please.
From what I understand back then "well regulated" meant well equipped, or well running like a clock that is well oiled and keeping time. That the "militia", i.e. us were to be well equipped with weapons that were well maintained and functioning when needed. So that if called the farmer or other person didn't have a rusty weapon and no ammunition and would be useless.
Treat? I don't understand your question.
The Militia Act, written one year after the Bill of Rights was ratified, detailed what was expected of state militias -- organization, armament, training, etc. That is what was meant by a well regulated militia.
