Is osama bin laden really dead?

i just had to ask this question. when i heard that the americans had killed him at first i believed it, but then within hours they claimed they had "disposed of his body deep down in the sea where no body could find him". plus isn't it strange that the hanging of saddam hussein took place on TV for everyone to see, but when it comes to bin laden they cant even give us picture/video evidence of his death. what do you think is he really dead? this is a open question to discuss this or any other celebrity deaths which you think are just not true.
