Maybe NP, maybe not: an inquiry

[Keith McMullen]

" The Sedition Act of May 16, 1918, that made political prisoners of anyone
who criticized the criminal war machine passed off as a "government," or its
symbols, or the war effort itself. During the war, they censored the media,
all printed materials, and even the constitution itself. Robert Higgs
reported(3) that in "California the police arrested Upton Sinclair for
reading the Bill of Rights at a rally. In New Jersey the police arrested
Roger Baldwin for publicly reading the Constitution."
