"We are not impressed by the argument that law enforcement methods such as those under review are necessary to uphold our laws. The Constitution proscribes such lawless means irrespective of the end. And this argument flouts the basic principle that all people must stand on an equality before the bar of justice in every American court. Today, as in ages past, we are not without tragic proof that the exalted power of some governments to punish manufactured crime dictatorially is the handmaid of tyranny...."

"The Constitution of the United States stands as a bar against the conviction of any individual in an American court by means of a coerced confession. There have been, and are now, certain foreign nations with governments dedicated to an opposite policy: governments which convict individuals with testimony obtained by police organizations possessed of an unrestrained power to seize persons suspected of crimes against the state, hold them in secret custody, and wring from them confessions by physical or mental torture. So long as the Constitution remains the basic law of our Republic, America will not have that kind of government."
