It could be AEG is a mayor spill in trying to get MJ down in the past, and MJ came to insight that they tried to get the doctor under pressure maybe he wants to learn them a lesson, a expensive lesson. if he didn't get out that day he certainly would have died..
AEG have to admit they were very responsable for the extortion.
Maybe it's a lesson for all the artists who had the same sort of conditions aswell.
but it's just my thought.
