Alexander Hamilton -

If the representatives of the people betray their constituents, there is then no resource left but in the exertion of that original right of self-defense which is paramount to all positive forms of government, and which against the usurpations of the national rulers, may be exerted with infinitely better prospect of success than against those of the rulers of an individual state. In a single state, if the persons intrusted with supreme power become usurpers, the different parcels, subdivisions, or districts of which it consists, having no distinct government in each, can take no regular measures for defense. The citizens must rush tumultuously to arms, without concert, without system, without resource; except in their courage and despair.

Alexander Solzhenitsyn -

Oh how we burned in the prison camps, later thinking: what would things have been like if every police operative, when he went out at night to make an arrest, had been uncertain whether he would return alive? If, during periods of mass arrests, people had not simply sat there in their lairs, paling with terror at every bang of the downstairs door and at every step on the staircase, but had understood that they had nothing to lose and had boldly set up in the downstairs hall an ambush of half a dozen people with axes, hammers, pokers or whatever was at hand? The organs would very quickly have suffered a shortage of officers and transport and, notwithstanding all of Stalin's thirst, the cursed machine would have ground to a halt.
