From an article titled "U.S. probing alleged rape of Sunni woman" by Oren Dorell in the USA Today:

Ahmed Abdullah, 29, a Sunni from Zaiona, had doubts [about whether or not a 20-year-old Iraqi was raped by members of the Iraqi police force]. "I don't believe that Iraqis will rape a woman. We don't have such a culture. We might kill, behead or do torture, but rape — I don't think so," he said.
