Every single one of those kids is just as important as Elizabeth Smart, that they all don't get the same coverage is reprehensible, but lets not forget this is still some kid who was kidnapped by a sicko, no matter if her parents are rich or not.
Don't lose sight of that, and remember it when something like this happens in your neck of the woods.
If it were my child, I would get in front of every camera I could find and say simply "98% of kidnappers get caught, when you are caught I will make sure it is by someone who works for me, and you and ytour entire family will die slow, painful deaths, unless you return my child immediately, in which case, you will be let go by my people". When they returned my child, they would live for a year in my basement, well, I guess you could call it live...
