Albinos hunted for their limbs because they bring good luck

ABC News reports on the hunting and killing of albinos in Tanzania, Burundi and Ghana, because "witch doctors" are telling the local populations that potions made from the limbs of albino people bring good luck and wealth. Recent cases included that of a woman who was attacked in her home at night, and whose arms have been cut off, and that of a 7-year old kidnapped at gun point, and whose body was found headless and without a hand the following day. During the past two years alone 54 Tanzanian albinos have been murdered so that their limbs and genitals could be harvested. The response of the Tanzanian government has included the suspension of licenses to witch doctors. Witch doctors have licenses??
