A cellphone video of a group of men raping a 17-year-old mentally ill girl has brought to light an often unreported issue in South Africa. The recording spread until it made its way to a tabloid that helped identify the perpetrators. These cases are rampant in South Africa, activists say. Of the 600,000 estimated rapes every year, only one in nine is reported, research shows. According to the director of a sexual violence organization, social attitudes toward women, early sexualization of children, an overloaded criminal-justice system, and low conviction rates for rape can be blamed for the epidemic.
