It is part of the established tradition in the use of juries as instruments of public justice that the jury be a body truly representative of the community. For racial discrimination to result in the exclusion from Jury service of otherwise qualified groups not only violates our Constitution and the laws enacted under it, but is at war with our basic concepts of a democratic society and a representative government. We must consider this record in the light of these important principles. The fact that the written words of a state's laws hold out a promise that no such discrimination will be practiced is not enough. The Fourteenth Amendment requires that equal protection to all must be given — not merely promised.

Our Founders were no more willing to let the content of their prayers and their privilege of praying whenever they pleased be influenced by the ballot box than they were to let these vital matters of personal conscience depend upon the succession of monarchs. The First Amendment was added to the Constitution to stand as a guarantee that neither the power nor the prestige of the Federal Government would be used to control, support or influence the kinds of prayer the American people can say -- that the people's religions must not be subjected to the pressures of government for change each time a new political administration is elected to office. Under that Amendment's prohibition against governmental establishment of religion, as reinforced by the provisions of the Fourteenth Amendment, government in this country, be it state or federal, is without power to prescribe by law any particular form of prayer which is to be used as an official prayer in carrying on any program of governmentally sponsored religious activity.

The liberty of every American citizen freely to come and to go must frequently, in the face of sudden danger, be temporarily limited or suspended. The civil authorities must often resort to the expedient of excluding citizens temporarily from a locality.
