Jolie adopted the child from an orphanage - so it was an orphan. She didn't go to these people and ask them to select a child for her, she did it herself when she visited the orphanage in cambodia. She simply looked for their help in bringing the child over and adopting it, but they weren't involved in finding the child (and thus "acquiring" one that wasn't an orphan).
- also were the babies actually stolen, or was it a case that they were "just" misrepresented as orphans?
