DOJ Raids Communist Meeting in Bridgman, Michigan
U.S. Justice Department officials, aided by local police, raided a secret meeting of the Communist Party of America being held in Bridgman, Michigan. The Communists were apparently tipped off, however, and the top leaders managed to escape. Several were subsequently prosecuted under the Michigan Criminal Syndicalism law. One of the problems with the raid was that there was no federal law that applied to the people attending the meeting. (The Smith Act, which made it a crime to advocate the overthrow of the government, was not passed until June 29, 1940.) The ACLU subsequently issued a report condemning the raid and other violations of civil liberties by the U.S. Justice Department: The Nationwide Spy System Centering in the Department of Justice (1924).
