Palmer Raids: Mass Deportations Without Due Process (1919-1920)
Attorney General A. Mitchell Palmer orchestrated raids targeting suspected communists and anarchists, arresting over 10,000 people—mostly immigrants—without warrants. Approximately 3,500 were held for deportation; 556 were ultimately deported. The raids were conducted without the Alien Enemies Act, using standard immigration law.
Acting Secretary of Labor Louis Post reviewed cases individually and canceled most deportation orders, finding insufficient evidence.
The raids discredited Palmer politically and strengthened support for civil liberties, contributing to the founding of the ACLU in 1920.
The Palmer Raids demonstrated what happens when the executive branch bypasses due process in the name of national security. The finding that 75% of the Venezuelan deportees had no criminal record echoes Louis Post's discovery that most Palmer raid detainees lacked evidence of wrongdoing.
