[America’s intelligence gathering] capability at any time could be turned around on the American people and no American would have any privacy left. Such is the capability to monitor everything: telephone conversations, telegrams, it doesn’t matter. There would be no place to hide.
If this government ever became a tyrant, if a dictator ever took charge in this country, the technological capacity that the intelligence community has given the government could enable it to impose total tyranny, and there would be no way to fight back because the most careful effort to combine together in resistance to the government, no matter how privately it was done, is within the reach of the government to know. Such is the capability of this technology.
I don’t want to see this country ever go across the bridge. I know the capacity that is there to make tyranny total in America, and we must see to it that [the NSA] and all agencies that possess this technology operate within the law and under proper supervision so that we never cross over that abyss. That is the abyss from which there is no return.
Senator Frank Church on Meet The Press, 17 August 1975
"The more power a government has the more it can act arbitrarily according to the whims and desires of the elite, and the more it will make war on others and murder its foreign and domestic subjects. Power will achieve its murderous potential. It simply waits for an excuse, an event of some sort, an assassination, a massacre in a neighboring country, an attempted coup, a famine, or a natural disaster, to justify the beginning of murder en masse."
R. J. Rummel, Mass Murder and Genocide, 1994
