An interesting thing about "well regulated militia" is if you put that 2nd Amendment in the context of Article III, Section 3: "Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort."

Put the context in a proposition for debate: Resolved, that any citizen who uses his or her weapons against the United States commits treason.
