The first Red Scare continues/the Palmer Raids begin: While the army and navy of the United States are in Russia making “the world safe for democracy,” (Federal) Bureau of Investigation agents (acting under color-of-law) begin arresting over 5,000 alien residents—without warrants or evidence of a conspiracy to overthrow the Federal government.  The basis for the arrests is membership in a labor union or an alternative (Farmer-Labor, Prohibition, Socialist, et cetera) political party, or being a foreigner working in a building that housed an organization deemed to be “subversive.”

       NOTE: A. Mitchell Palmer, attorney general of the United states, chose this date as it was the second anniversary of the beginning of the Russian Civil War.
