"Wouldn't it be up to the defendant and plaintiff to provide expert witnesses? I would think any number would be suitable - military historians, for example."

Would you expect all state militias to equip themselves with the same weapons? As a state, would you accept some military historian telling you what you may have in the way of weaponry?

You keep mentioning "the state militia". Where are these state militia's. I have never heard of one.
Where are they and what does the so called "state militia" have to do with private ownership of firearms?
Are you implying that the state is supposed to determine what we can own and do with private property?
You keep ignoring free individuals. Why?

Sure, if he were my expert witness.

state militias

The 2nd doesn't say "state militias". It says "militia", and that from a federal perspective, including the President's ability to "call out" and Congress' ability to "train and equip" it.
