I find the recent disclosures concerning U.S. Government testing of the effects of radiation on unknowing human subjects to be yet more evidence that you simply cannot trust the government with your own personal safety. Some people, given positions of power, will naturally abuse those positions, often even if such abuse could cause severe injury or death. I see little reason, therefore, to simply "trust" the U.S. government -- and given that the U.S. government is about as good as they get, its obvious that NO government deserves the blind trust of its citizens. "Trust us, we will protect you" rings quite hollow in the face of historical evidence. Citizens must protect and preserve their own privacy -- the government and its centralized cryptographic schemes emphatically cannot be trusted. Perry
