Quote from the article:

Again, among the most prominent high end purchasers within the international child sex industry are Saudi princes. Saudi princes will also "special order" children through a picture of the child in a media or give a description of a desired child. In these cases the child is "snatched" from in front of their house, coming from school or at a store while with a parent. The child is in Saudi Arabia before the local police develop a search procedure.

Yet another reason NOT to ever post pictures of your kids online. I've read plenty of odd stories of someone targeting a specific kid in a store while mom is not looking. Maybe that was a "special order kid." How disgusting. :/
