I see it this way, I know it is fake, but this is what the person who made it might be saying:
-if it's done by someone who believes in the hoax, then Janet is making Muray a hero for accepting this role and being bashed in the press and allowing MJ to be free.
-If MJ died, then I see this as Janet holding Murray as someone who set MJ free, free from his pain and suffering. Mentally and physically. Because of Murray's actions, MJ is now venerated once again, something that may never have happend if he had lived.
-If MJ died and someone else is behind this (Sony, AEG) and Murray is just an innocent fall guy, then janet is honoring him for taking the fall. She can't speak about it publicly, so this is her way of saying Murray is innocent.
-If this was made by someone who hated MJ...then I think we all know what this implies.....
