Glad you mentioned this case, and the tragedy is great indeed, and their stories need to be heard. But it seems you miss the point.
I doubt it's a big story in africa, where millions are dying of starvation, but thats another topic... this is not unique. 18 years, okay, that's a long time.
Why do you think that news media all over the world are gripped by this case, whether it's the BBC, Australian media, Africa etc? Is it perhaps because of the uniqueness of the Girl turning up alive after so long? We hardly ever hear of children kidnapped by strangers, (much less by a criminal) being found alive after 18 years.
I may not get what? Again, I was merely stating that this case isn't as unique as you think, bringing another example. I don't see where I show a lack of understanding for the situation.
You may not get it Zidane, but it seems many many other people do. This story is going to grip the public imagination for weeks to come, and prompt for more action to protect these children.
