Whitney's dead!!! Who did it?????

Ok. They need to stop bashing Whitney...Yeah she was on drugs and drinking, but if you pay attention to all the info coming out you can see they are not questioning who they really need to...Ray J was with her while in CA. going out and partying...Why not question him??? And what about Brandy and that secret note??? She was looking so strange when she read it and you notice Whitney really didnt have any words for her...Get them they are guilty...And what about Clive Davis???
