Bad men, like good men, are entitled to be tried and sentenced in accordance with law, and when it is shown to us that a person is serving an illegal… - Hugo Black

The Establishment Clause, unlike the Free Exercise Clause, does not depend upon any showing of direct governmental compulsion and is violated by the enactment of laws which establish an official religion whether those laws operate directly to coerce nonobserving individuals or not. This is not to say, of course, that laws officially prescribing a particular form of religious worship do not involve coercion of such individuals. When the power, prestige and financial support of government is placed behind a particular religious belief, the indirect coercive pressure upon religious minorities to conform to the prevailing officially approved religion is plain. But the purposes underlying the Establishment Clause go much further than that. Its first and most immediate purpose rested on the belief that a union of government and religion tends to destroy government and to degrade religion. The history of governmentally established religion, both in England and in this country, showed that whenever government had allied itself with one particular form of religion, the inevitable result had been that it had incurred the hatred, disrespect and even contempt of those who held contrary beliefs. That same history showed that many people had lost their respect for any religion that had relied upon the support of government to spread its faith. The Establishment Clause thus stands as an expression of principle on the part of the Founders of our Constitution that religion is too personal, too sacred, too holy, to permit its "unhallowed perversion" by a civil magistrate. Another purpose of the Establishment Clause rested upon an awareness of the historical fact that governmentally established religions and religious persecutions go hand in hand. The Founders knew that only a few years after the Book of Common Prayer became the only accepted form of religious services in the established Church of England, an Act of Uniformity was passed to compel all Englishmen to attend those services and to make it a criminal offense to conduct or attend religious gatherings of any other kind-- a law which was consistently flouted by dissenting religious groups in England and which contributed to widespread persecutions of people like John Bunyan who persisted in holding "unlawful [religious] meetings . . . to the great disturbance and distraction of the good subjects of this kingdom . . . ." And they knew that similar persecutions had received the sanction of law in several of the colonies in this country soon after the establishment of official religions in those colonies. It was in large part to get completely away from this sort of systematic religious persecution that the Founders brought into being our Nation, our Constitution, and our Bill of Rights with its prohibition against any governmental establishment of religion.

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.

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.
