Pretty sure that the uprising envisioned against a tyrannical government isn't just one crazy dude. Indeed, if a political interest could not gather a much larger force to fight this tyranny then that would be considered overwhelming evidence that its grievances were not valid.
Right, so what constitutes a justifiable uprising? Ten people? One thousand people?
There will never be an uprising of a thousand people. An uprising will only occur if it is certain of widespread support.
And that is the point. If you have real grievances that can only be addressed by the violent overthrow of the government, you should be able to assure a broad base of support. A revolt on the order of a thousand people or less would likely constitute either a gross overreaction to a lesser problem or the ravings of a small fringe element.
