by the United States Court of Appeals for the Eighth Circuit, Finney v. Arkansas Board of Correction… (1974 | noyear)
“ A person does not forfeit his First Amendment rights simply because he acquires a bad reputation. In like manner, a prisoner does not lose the protection of the First Amendment simply because those with whom he wishes to communicate are "disreputable" in the eyes of the prison administrators. This is not to say that when questions of institutional security are involved, officials may not be justified in limiting correspondence on a particular basis. We simply find this excuse too broad to justify application of the mailing list system to all inmates. ”
