Yeah, I just checked, when you read the bill of rights, the Second Amendment does not define what “the Militia” is. But the Fifth Amendment sort of does, and its definition of “the Militia” is in a sentence that also contains the phrase “the land or naval forces” and “in time of War or public danger”. When read in the context of the document and of the history of the US and its armed forces in 1798, “the Militia” was meant more as an federal army or state reserve fighting forces (like today’s National Guard), not as a government watchdog group looking out for tyranny and poised to revolt against it.
