"The Founders didn’t want guns for duck hunting; they wanted a deterrent against a government which could tax them, search their homes, seize their property ... "

I'd like to be present when that second amendment defense as "the right to overthrow duly elected governments you disagree with" is argued before the US Supreme Court.
