who became the Superintendent of its newly established Women's Protective Division, especially noted for helping women during a time that PPB's officers focused on enforcement and patrol of people who could pay them under the table. Unattached women had arrived en masse for the 1905 Lewis and Clark Centennial Exposition. In 1915, the "Metropolitan Police Force" changed its name to the Bureau of Police. Four years later, the bureau became the first, in the United States, to use a police radio. Sybil Plumlee, also considered to be a pioneer in the field, served in the Women's Protective Division from 1947 to 1967. PPB's "Red Squad" was formed in the 1910s to fight a rise of communism, the labor movement, and other left-wing efforts. Its membership was documented to overlap with Oregon's branch of Ku Klux Klan in the 1920s and the pro-Nazi antisemitic Silver Shirts in the 1930s; Red Squad Captain Walter Odale was part of American Defenders, a spinoff of the Silver Shirts. In one of Red Squad's "Weekly Report of Communist Activities", Odale stated Portland was the third-largest center of Nazi activity in the country. The Squad interrogated a student leader at Lincoln High School, and within days of this becoming public in 1937, the Red Squad was disbanded. Still, by 1940, the Silver Shirts were confident that police would side with their organization "if any trouble starts in Portland". By 1923 it was estimated over half of the PPB were also members of the Klan. In 1964, Black Albina resident Cleotis Rhodes was shot during a traffic stop, which led to his death. The use-of-force guidelines were amended by the new police chief to note firearms should only be used related to felonies. In a 1968 City Club of Portland Report on Law Enforcement, PPB were described as having "the right to stop and frisk someone because his skin is black and he is in the black part of town." Albina, the majority-Black area of Portland, was deliberately neglected, as police and Mayor Terry Schrunk confirmed. This was intensified by the ghettoization (through redlining and other means), concentrating Portland's Black population in Albina. Portland police were disproportionately white (1% were Black) even compared to the low percentage of Blacks in Portland (7%). Attitudes were reflected in a 1966 survey, where 86% of officers thought the civil rights movement was happening "moving too fast". Youth in the Albina
