It already has, repeatedly - but that's totally orthogonal. To imply that gun owners are worried about systematic government oppression that would necessitate an uprising is not an accurate portrayal of conventional wisdom, it's a half-assed attempt at interpreting the Constitution and extrapolating gun ownership rationale. But most gun owners in the US (that I know - and I know quite a few) possess them for hunting, collecting, and sport shooting, in that order.
