On June 22, 1918, an organizer for the Industrial Workers of the World (IWW) named Walker Smith was arrested at his home in Seattle. Two Scottish sisters, Janet and Margaret Roy, were arrested with him, and unlike Smith and the many others he consorted with, they were not American citizens. As foreigners, the sisters’ experience in the American legal system, the newspaper coverage devoted to them, and their attempts to thwart the immigration laws that targeted them provide an example of how American immigration law and practice sought to ideologically sort and control new arrivals to the United States.
