but the fact remains that colonial America's farmers were up against a professional army (and were getting their butt's kicked all over the continent) and still eventually won, while you asserted that it couldn't happen.
Taking the sheer numbers of armed people in the US - most of whom are better planners and are able to organize better than Malvo and friend, and far more likley to have popular support in that they would not be random murderers as were the "snipers" - instead they would be fighting not merely on the physical front but also in the ideological front with the many resources available for communication including friends in high places and in the police forces and military, I would say that a corrupt government wouldn't stand a chance against angry citizens who were not only actively fighting but no longer formally working and producing income to tax. The government could be quickly exhausted, its resources curtailed, and its forces demoralized, yet would still have to watch its back lest another government intervene or take advantage.
