Today most Americans seem to have forgotten the ancient evils which forced their ancestors to flee to this new country and to form a government stripped of old powers used to oppress them. But the Americans who supported the Revolution and the adoption of our Constitution knew firsthand the dangers of tyrannical governments. They were familiar with the long existing practice of English persecutions of people wholly because of their religious or political beliefs. They knew that many accused of such offenses had stood, helpless to defend themselves, before biased legislators and judges.
