William O. Douglas,
Dennis v. United States — Dissenting Opinion
“ The wide difference between advocacy and incitement, between preparation and attempt, between assembling and conspiracy, must be borne in mind. In order to support a finding of clear and present danger, it must be shown either that immediate serious violence was to be expected or was advocated, or that the past conduct furnished reason to believe that such advocacy was then contemplated. Those who won our independence by revolution were not cowards. ”
