If it wasn't for MJ high paid lawyers, he would have been hung out to dry. If the average person were to use the MJ defence from MJ own words "that it is only natural to sleep together", they would be found guilty with no questions. Technically you are right, there is nothing wrong with just sleeping with a minor child but in this day and age with all the freaks out there it is not acceptable behaviour.
I also agree with you that the children's parents should be held accountable for allowing their child to sleep in MJ room but you are opening up another can worms. By saying they endangered their child is admitting that there was a lot more going on there than just innocent sleep overs.
