Back then it might have been possible to overthrow the government with force, but today it is pretty much impossible. Citizens might have guns, but the government has the army, the navy, and the air force. It doesn't matter how many guns you have, they are useless against tanks and all the other goodies the military has. Not to mention that if you even plan to stir up trouble in Washington, the CIA, FBI, and the NSA would be on your ass. Yea good luck with that. In my opinion that amendment is outdated.
