Just went and heard it.
Wow...so he was already dead when the 911 call was made, then? They paramedics must've been able somehow to get his heart beating again when they got there...hence reports of him being in a coma at the hospital. Imma take a wild guess and say the last thing that doctor wanted to do was make that 911 call and say MJ was dead...which is why the caller simply said Michael wasn't responding to anything. No heartbeat and no breathing = deceased, but he didnt' want to say it.
I think the idea that paramedics got there possibly got his heart started again could mean Michael was trying to fight his way back...just couldn't hold on, maybe.
I know this is sad, but the more I know I feel more closure. It's the not knowing what the hell happened here that's hardest.
