Edward Terry Sanford,
Whitney v. California — Opinion of the Court
“ That such united and joint action involves even greater danger to the public peace and security than the isolated utterances and acts of individuals is clear. We cannot hold that, as here applied, the Act is an unreasonable or arbitrary exercise of the police power of the State, unwarrantably infringing any right of free speech, assembly or association, or that those persons are protected from punishment by the due process clause who abuse such rights by joining and furthering an organization thus menacing the peace and welfare of the State. ”
