I agree that the parents share a large responsibility, with ANYTHING their child does... They can't however teach their child to be more intelligent -- perhaps a little -- or correct every single bad habit they have. The child could have hopped on their older siblings xbox 360 in the middle of the night, who knows... I do know for sure that it's unlikely any 10 year old would want their parents to know about them taking nude pictures of themselves, let alone sending them over the internet. I'm certain that part was done in secret, and perhaps it was the parents who busted the criminals and got the police on the culprit in the end.
Though regardless of responsibility, we all know the real bad guy here is the dude with the child porn.
