As a result of such accounts, a number of Japanese prison-camp officers and guards were convicted of torture that clearly violated the laws of war. They were not the only defendants convicted in such cases. As far back as the U.S. occupation of the Philippines after the 1898 Spanish-American War, U.S. soldiers were court-martialed for using the "water cure" to question Filipino guerrillas.
More recently, waterboarding cases have appeared in U.S. district courts. One was a civil action brought by several Filipinos seeking damages against the estate of former Philippine president Ferdinand Marcos. The plaintiffs claimed they had been subjected to torture, including water torture. The court awarded $766 million in damages, noting in its findings that "the plaintiffs experienced human rights violations including, but not limited to . . . the water cure, where a cloth was placed over the detainee's mouth and nose, and water producing a drowning sensation."
In 1983, federal prosecutors charged a Texas sheriff and three of his deputies with violating prisoners' civil rights by forcing confessions. The complaint alleged that the officers conspired to "subject prisoners to a suffocating water torture ordeal in order to coerce confessions. This generally included the placement of a towel over the nose and mouth of the prisoner and the pouring of water in the towel until the prisoner began to move, jerk, or otherwise indicate that he was suffocating and/or drowning."
The four defendants were convicted, and the sheriff was sentenced to 10 years in prison.
