If any other 40-year-old slept with a boy, I'd assume sexual molestation. Michael Jackson, however, is so weird that you can't assume anything. I think he was innocent.
I also think his trial was so unfair it made me sick. The judge allowed (because of a California law that should be ruled unconstitutional) unproven allegations about past alleged behavior to be heard. You can't do that to a murderer, or any other criminal, just a suspected child molester. The judge consistently ruled against Jackson. This trial was a travesty, but sanity won out in the jury room.
He was charged by a DA who has been after him for years. A DA who is conducting a vendetta against someone should not be allowed anywhere near the case.
Allegations about Jackson have been rampant for years. It is not possible that the boy's mother was unaware of them. The fact that she allowed her child to sleep with him shows clearly that her intention from the beginning was to have her son be molested, and then sue Jackson for millions. If it happened, I bet the boy threw himself at Jackson, hoping (per his mother's instructions) that he would be molested.
