A profound judgment of today's riots was expressed by Victor Hugo a century ago. He said, 'If a soul is left in the darkness, sins will be committed. The guilty one is not he who commits the sin, but he who causes the darkness.' / The policymakers of the white society have caused the darkness; they create discrimination; they structured slums; and they perpetuate unemployment, ignorance and poverty. It is incontestable and deplorable that Negroes have committed crimes; but they are derivative crimes. They are born of the greater crimes of the white society. When we ask Negroes to abide by the law, let us also demand that the white man abide by law in the ghettos.
