Obviously, the first and second paragraph of the Declaration of Independence clearly state that when a government fails to serve the people properly and abuses their power etc. that it is the right of the people, and their duty, to overthrow such a form of government. Let's say someone feels that the govt. has gone too far, has reach the point by which elections can not properly reforms it, and thinks that the only way to restore legitimacy to the govt. is to abolish it and start anew. So he goes, kills a bunch of government officials, and is of course arrested. Now, it seems, regardless of his reasoning, this guy would be sent to jail his whole life, or executed, depending on the state. However, by his reasoning, he was doing what is best for America, trying to bring down a corrupt system the only way he saw fit. It seems like it's pretty much up to the judge/jury whether or not the officials he killed were evil/corrupt/abusive enough to justify being killed by a vigilante/revolutionary, right?
