I guess the question still remains as to who decided she needed chloralhydrate rather than an emergency room visit. This does not answer why in the world she was taking that drug.
Do you really care why she was taking chloralhydrate? I sure don't.
Compared to other problems we have here in America today her death was nothing. Be concerned for the living not some dead idiot who trashed her marriage vows.
I can see how the threshold for an emergency room visit is a lot higher for a major celebrity. Causes commotion in the ER and media fall-out afterwards. Also, IIRC her bodyguard was a licensed EMT.
