I'm of two minds about this. We can certainly say that MJ was very odd, and suspect many things. And he would not be the first person to get away with outrageous behavior through a combination of money, litigiousness, bravado, lies and confusion. But one can also imagine variations. Imagine for example that you're MJ. You're surpassingly, flamboyantly peculiar, rich, so popular you can do almost anything you want, immature, emotionally needy, etc. etc. - definitely not an ordinary guy. You might even be a pedophile, in your inner self, and wish like anything that you could get away with having sex with boys. But you also might know you can''t, and know where the boundaries are, and figure that it's enough not to cross them even if you come close, and to be fairly open and public about what you're doing. Unfortunately for him, his situation makes things look different. I think it remains possible that the reason no charges stuck is that he did not actually cross the line, even though outside observers might easily be right in believing that he would have liked to.
It's not that far fetched. We judge much behavior by our assumptions. Often our fears are warranted, and our assumptions reasonable or at least forgiveable even if they turn out to be wrong.
It's a well trodden path, for example, in the literature of psychology, where the behavior of a person is seen entirely differently when that person is first presumed to be insane. Things we normally do are interpreted as symptomatic of abormality.
When a mother acts in a certain way with a child, it's seen differently from when a strange man does the very same thing, and we're well advised to be suspicious, but every once in a while it's not what it seems.
I still wouldn't let any kid of mine spend the night in Michael Jackson's bedroom, and I wouldn't be surprised if he turned out to be a just plain child molester and as awful as many believe. But I wouldn't rule out the possibility that he was not.
