Why No Talk on Arab Slave Trade of Blacks?

According to a Human Rights Watch/Africa report, routine punishments for slaves in Mauritania – for the slightest fault – include beatings, denial of food and prolonged exposure to the sun, with hands and feet tied together. More serious infringement of the master’s rule (in American slave-owning parlance, “getting uppity”) can lead to prolonged tortures known as “the camel treatment,” in which the slave’s body is slowly torn apart; the“insect treatment,” in which tiny desert insects are inserted and sealed into the ear canal until the slave is driven mad; and“burning coals,” a torture not fit to describe in a family newspaper.

There's no shortage of the whites doing wrong to blacks, but why aren't these stories getting the same sort of headlines, for slavery going on, today!?
