While the machinery of law enforcement and indeed the nature of crime itself have changed dramatically since the Fourth Amendment became part of the Nation's fundamental law in 1791, what the Framers understood then remains true today - that the task of combating crime and convicting the guilty will in every era seem of such critical and pressing concern that we may be lured by the temptations of expediency into forsaking our commitment to protecting individual liberty and privacy.

We current justices read the Constitution in the only way that we can: as 20th-century Americans.

Lawyers, before any other group, must continue to point out how the system is really working-how it actually affects real people. They must constantly demonstrate to courts and legislatures alike the tragic results of legal nonintervention. They must highlight how legal doctrines no longer bear any relation to reality, whether in landlord and tenant law, holder in due course law, or any other law. In sum, lawyers must bring real morality into the legal consciousness

The framers knew that liberty is a fragile thing, and so should we.

If our free society is to endure, those who govern must recognize human dignity and accept the enforcement of constitutional limitations on their power conceived by the Framers . . . . Such recognition will not come from a technical understanding of the organs of government, or the new forms of wealth they administer. It requires something different, something deeper-a personal confrontation with the wellsprings of our society.

The genius of the Constitution rests not in any static meaning it might have had in a world that is dead and gone, but in the adaptability of its great principles to cope with current problems and current needs.

The calculated killing of a human being by the state involves, by its very nature, an absolute denial of the executed person's humanity. The most vile murder does not, in my view, release the state from constitutional restraint on the destruction of human dignity.
