context: The Supreme Court decided about the same time that a prison regulation that restricts prisoners' contact with the press is valid but only "[s]o long as this restriction operates in a neutral fashion, without regard to the content of the expression." And it has likewise been decided that a prison regulation that operates in the area of inmates' First Amendment rights must have some rational connection with a legitimate governmental interest, and that regulation must "operate[] in a neutral fashion, without regard to the content of the expression."
