I've been thinking about it too but more on the cases in the States. Remembering the abductions where the victim is recovered it seems the young girl from Salt Lake City was a prisoner of just the kidnapper.
Remember the young boy who spent years with his abuser and had the courage to go to the police when he (abuser) brought another really little kid "home".
It's horrible enough to hear about those, but even more to think that some of the others who are missing may be forced to be prostitutes.
Which is why I would support torture as a last resort to obtain information in this case
