“This is now the twelfth day of rioting in France. They have been rioting for almost two weeks. And France has still not surrendered. That's like a record.”

On the Mindless Menace of Violence (1968)
Context: What has violence ever accomplished? What has it ever created? No martyr's cause has ever been stilled by an assassin's bullet. No wrongs have ever been righted by riots and civil disorders. A sniper is only a coward, not a hero; and an uncontrolled, uncontrollable mob is only the voice of madness, not the voice of reason. Whenever any American's life is taken by another American unnecessarily — whether it is done in the name of the law or in the defiance of the law, by one man or a gang, in cold blood or in passion, in an attack of violence or in response to violence — whenever we tear at the fabric of the life which another man has painfully and clumsily woven for himself and his children, the whole nation is degraded.
