History teaches that grave threats to liberty often come in times of urgency, when constitutional rights seem too extravagant to endure. The World Wa… - Thurgood Marshall

The legal system can force open doors, and sometimes-even knock down walls, but it cannot build bridges. That job belongs to you and me. The country can't do it. Afro and White, rich and poor, educated and illiterate, our fates are bound together. We can run from each other, but we cannot escape each other. We will only attain freedom if we learn to appreciate what is different, and muster the courage to discover what is fundamentally the same. America's diversity offers so much richness and opportunity. Take a chance, won't you? Knock down the fences, which divide. Tear apart the walls that imprison you. Reach out. Freedom lies just on the other side. We shall have liberty for all.

At a time in our history when the streets of the Nation's cities inspire fear and despair, rather than pride and hope, it is difficult to maintain objectivity and concern for our fellow citizens. But, the measure of a country's greatness is its ability to retain compassion in time of crisis. No nation in the recorded history of man has a greater tradition of revering justice and fair treatment for all its citizens in times of turmoil, confusion, and tension than ours. This is a country which stands tallest in troubled times, a country that clings to fundamental principles, cherishes its constitutional heritage, and rejects simple solutions that compromise the values that lie at the roots of our democratic system.

The central problem with Chicago's ordinance is that it describes permissible picketing in terms of its subject matter. Peaceful picketing on the subject of a school's labor-management dispute is permitted, but all other peaceful picketing is prohibited. The operative distinction is the message on a picket sign. But, above all else, the First Amendment means that government has no power to restrict expression because of its message, its ideas, its subject matter, or its content. [Citations.] To permit the continued building of our politics and culture, and to assure self-fulfillment for each individual, our people are guaranteed the right to express any thought, free from government censorship. The essence of this forbidden censorship is content control. Any restriction on expressive activity because of its content would completely undercut the '"profound national commitment to the principle that debate on public issues should be uninhibited, robust, and wide-open."
