Not trying to take things out on a tangent on purpose but it is not secret that Bush family and Bin Landen family did a lot of business together for years before 911. That has been well documented but couldn't track down the best sources at this moment.
Osama Bin Laden was treated at a American military hospital in Saudi Arabia, if I remember correctly it was kidneys and maybe dialysis, it seemed serious. This is why the theory of Osama being CIA asset surfaced since he was from the time of mujahedin in Taliban.
I was very surprised to hear he was raided and killed until I heard the news that he was expediently buried at sea and then the Navy Seal's Team 6 chinook helicopter goes down. Not much looks good in this story.
these are the quickest sources I could find

Canadian CBC The Fifth Estate did a great documentary on Bush and Bin Laden family before and after 911 involvement but it seems to be taken down now. Too bad, as not much from CBC is without biased these days.
I think I did find it.
