One of the most controversial laws ever passed in the United States, the Espionage Act of 1917 (ch. 30, tit. I § 3, 40 Stat. 217, 219), and an amendment to it passed in 1918 sometimes referred to as the Sedition Act, were an attempt to deal with the climate created in the country by WORLD WAR I. While most of the Espionage Act was straightforward and non-controversial, parts of this legislation curtailed FREEDOM OF SPEECH in such a way as to draw an outcry from civil libertarians.

While more comprehensive, these passages were not much different than what had been in previous laws against spying and espionage.
But the Espionage Act went further. It deemed a criminal anyone who, "when the United States is at war, shall willfully make or convey false reports or false statements with intent to interfere with the operation or success of the military or naval forces of the United States or to...
