Well, whatever the case, I agree with Jeri that this is an issue of torture and murder, not religion and not witchcraft. Instead of pointing the finger of blame at one group or another, people of good will need to unite in opposition to the injustice that occurred.
Time and time again in discussions here, groups are blamed for things they would never, ever approve. Nobody in his right mind approves or condones torture, murder, abuse, or any sort of crime. In almost every situation, it's foolhardy to blame a group for the crimes of a few members.
