Among the numerous examples, Wallach cites one involving four Japanese defendants who were tried before a U.S. military commission at Yokohama, Japan, in 1947 for their treatment of American and Allied prisoners. Wallach writes, in the case of United States of America vs. Hideji Nakamura, Yukio Asano, Seitara Hata and Takeo Kita, "water torture was among the acts alleged in the specifications ... and it loomed large in the evidence presented against them."
Hata, the camp doctor, was charged with war crimes stemming from the brutal mistreatment and torture of Morris Killough "by beating and kicking him (and) by fastening him on a stretcher and pouring water up his nostrils." Other American prisoners, including Thomas Armitage, received similar treatment, according to the allegations.
Armitage described his ordeal: "They would lash me to a stretcher then prop me up against a table with my head down. They would then pour about 2 gallons of water from a pitcher into my nose and mouth until I lost consciousness."
Hata was sentenced to 25 years at hard labor, and the other defendants were convicted and given long stints at hard labor as well.
Wallach also found a 1983 case out of San Jacinto County, Texas, in which James Parker, the county sheriff, and three deputies were criminally charged for handcuffing suspects to chairs, draping towels over their faces and pouring water over the towel until a confession was elicited. One victim described the experience this way: "I thought I was going to be strangled to death. ... I couldn't breath."
The sheriff pleaded guilty and his deputies went to trial where they were convicted of civil rights violations.
All received long prison sentences. U.S. District Judge James DeAnda told the former sheriff at sentencing, "The operation down there would embarrass the dictator of a country."
