They make one mistake like this and they can't be parents? If this was a planned kidnapping, if it didn't happen then, it would have happened another time.
Sure they made a HUGE mistake by leaving them in the room alone. But why blame the parents!! The blame should be on the guy that kidnapped them in the first place. What kind of moron feels the need to kidnap a kid for any reasons!?! Plus it was in the security of a hotel?
Yes it could have been prevented, if they were under supervision. But they weren't. In response to the first thread, the blame should be on the idiot that kidnapped the girl in the first place, not the parents - it's not as if they asked for their child to be kidnapped - they simply made a stupid mistake by leaving their kids alone and as most people know at that age, it is a big no-no
