In Nigeria and the Congo, the torturing and murder of child witches is on the rise. All it takes is for someone to accuse and a child can be driven from his home, have nails driven into his head or be set afire to drive out the evil spirits. It seems incredible but there have been recent cases in ther States as well involving immigrants from the Caribbean.
Unusual birthmarks, misbehaving, epilepsy - all proof of witchcraft.
