Justice Douglas's concurrence reflected the absolutist position that only he and Black, among Supreme Court justices, ever fully subscribed to, namely that the phrase "no law" in the First Amendment ought to be interpreted very literally, and that all speech is immune from prosecution, regardless of the governmental interests advanced in suppressing some particular instance of speech. He briefly traced the history of the "clear and present danger" test, illustrating how it had been used over the years since its debut in "Schenck" to dismiss dozens of what Douglas viewed as legitimate First Amendment claims.
