Nothing like relying on a law from 1934 to hammer home the fact that government agencies can stomp freedom in to the dirt.
AFAIK, 1919 is when the Supreme Court decided the constitution wasn't binding:
We admit that, in many places and in ordinary times, the defendants, in saying all that was said in the circular, would have been within their constitutional rights. […] It is a question of proximity and degree. When a nation is at war, many things that might be said in time of peace are such a hindrance to its effort that their utterance will not be endured so long as men fight, and that no Court could regard them as protected by any constitutional right.This, despite the constitution clearly saying:
— from Schenck v. United States
Amendment I
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
