Do you think the kids parents have some responsibility for what may have occurred between Michael and their sons. What parent would allow their children to participate in frequent 'sleepovers' with a grown man who sometimes acted like a kid himself and had a questionable history.
The parents definitely have to take a lot of the blame. However, I can understand to an extent how Jackson was able to use his fame and status to manipulate even them.
You've got the most famous person on the planet and he wants you and your family to hang with him, he buys you expensive gifts, treats you like a family friend and takes you with him to luxury resorts.
I can imagine that many people would just be star struck and vulnerable to exploitation.
