I read this story in teh Guardian a few months ago.
Do you know what made me even more angry? The police did actually pursue 14 people involved in this crime, but those 14 actually included the wife of the rapist. Scapegoating her because apparently, according to the authorities, she had wanted the girl beaten.
Now, it was the village elders , a group of men, who decided that a raped girl should be beaten. Surely they're your first port of call? I bet those bastards get let off and they prosecute random scapegoats instead.
It does sound like it's the kind of thing that can be helped by education. I remember reading that the mother and father of the girl didn't realise that the sentencing by the village elders was against Bangladeshi law. They had no idea they could invoke the law to stop her being lashed. So awareness raising might help.
