him to co-author Impounded Peoples in 1946. While at Tule Lake, he kept careful records of daily camp life. Opler documented instances of abuse at the camp and worked with lawyer Wayne M. Collins on behalf of the internees. His records included an account of "The November Incident," a protest by the residents of the camp which resulted in the takeover of Tule Lake by the US Army. Author Barney Shallit remembered Marvin Opler at Tule Lake both fondly and vividly: "with his heavy red beard and his slow, deliberate movements, he looked ... like a benign, giant panda." Marvin's wife, Charlotte Opler, enrolled their son Ricky in the Japanese nursery camp at the center, making him the only Caucasian enrolled there. Marvin Opler noted the parallels between the revival of traditional Japanese culture among the largely acculturated internees at Tule Lake and the spread of the Ghost Dance religion among Plains Indian tribes in the 19th century. Opler pointed out that both were attempts by the colonized to reassert their dignity. Historian Peter Suzuki writes that most of the anthropologists who worked for the War Relocation Authority (WRA) accepted the government's action of interning the Japanese Americans as morally justified. Suzuki believes, however, that Marvin Opler's work was a model of the positive role that these anthropologists could have played. Suzuki suggests that Opler's acknowledgment of a wider social and political field as part of his analysis, Opler's criticism of the segregation of so-called "loyal" versus "disloyal" internees, and the respect that Opler paid to Japanese culture made his work such a model. At Tule Lake, Marvin Opler befriended several well-known Japanese American internees. One of these was Yamato Ichihashi, one of the first academics of Asian ancestry in the United States. Ichihashi wrote a comprehensive account of his experiences as an internee. Opler was impressed by the work of George Tamura, a Japanese American artist who spent his teenage years imprisoned at Tule Lake. Marvin Opler also co-authored an article on Senryū folk poetry with another internee, F. Obayashi, which was published in the Journal of American Folklore in 1945. In his book Threatening Anthropology anthropologist David H. Price discusses FBI documents from 1945 in which FBI Director J. Edgar Hoover ordered an FBI investigation of Marvin Opler after the discovery of a letter bearing the initial "M" in a Portland trash can. Marvin Opler was questioned by
