It's been a long time since I've researched anything on MJ, but I vaguely remember reading that they found the fingerprints of both MJ and some kid on porn mags that he had. Showing porn to kids is one of the main methods of grooming that child predators use, though I don't recall if they were adult magazines or CP magazines - not that either option would be good, really.

Edit: So after looking at this article on the fingerprints and this one on the CP they found, the story is a bit more complicated than that.

Do keep in mind that this blog is obviously very biased in favor of MJ, trying to downplay the fact that he kept magazines with nude photos of children, and speculating about what "real grooming" would look like and why MJs actions supposedly don't match what the author personally thinks a real attempt at grooming should be like.

If anyone wants to abide by the interpretations of this blog specifically be my guest, but I sure as hell still wouldn't let my kids near MJ.
