For several years, well-intentioned and good hearted schoolkids and some Christian groups have been raising money to buy the freedom of slaves in Sudan. According to the article, it costs $50 to buy a slave's freedom. However, it appears that at least some of these groups are the victims of a scam. Whenever the representatives from these groups showed up in a village, scores of "slaves" would be paraded before them so they can be purchased. These "slaves" were local villagers taking part in the scam. One Christian missionary reported to see some of his congregation among the "slaves."

I've read in the past that these slave purchases were actually increasing the market for slaves in the Sudan. It appears this story last week is a variation on the theme. It's sad that people with the best of intentions are being ripped off so flagrantly.
