This link is to an organisation trying to save the life of a woman in Iran who was sentenced to death by stoning. Rather than spam everyone with the info, I simply post the link here. I have little faith that a "culture" which will do such a thing will respond to a western-style online campaign and there is way too much information involved here which is impossible to verify. But one does what one can, even if that is only, "Here. See this. Remember this."
