What are the specific ual abuses allegedly carried out against the South African girls in Oprah's school?

Monday, Nov. 5: Oprah Winfrey held a widely publicized press conference today in answer to the allegations of ual ault carried out against at least 7 female students at the college she founded in South Africa for girls from disadvantaged homes. Various school personnel have been fired or suspended and more house cleaning will be soon at hand. The accusation of ual ault, however, is one that is often used by individuals with ulterior motives, e.g. the Duke University Soccer Team supposedly raping the stripper who was later proven to have completely fabricated her story. In this South African case, I personally give these girls the benefit of the doubt and do believe they were ually aulted...BUT...I have not heard any of the details. I'm wondering if there are truths, half-truths, and non-truths floating around in this story. Accusations of ual misconduct are HIGHLY emotional these days but I think it's important we get the facts before ping judgement.
