I think Hersh was trying to give you a true story. I think he had genuine sources whom he trusted. Bin Laden's compound, was just a short distance from a Pakistani military base. Something that large and that protected would be noticed by them and it appears they must have let it be. Because of the human ability to lie about things, it is hard to imagine we can divine the truth and be sure of any facts in this matter except:
From the beginning, the U.S. has treated this part of the world in the same way. Our actions in these locations could be stabilizing if they were only humane and a genuine effort to help these people cope with their lives. Instead, Pakistan, etc. etc. etc. are all political footballs for any chauvanistic politician in our country, and while politicians may pretend to be peace doves, if you give them their head, they act like the creatures in the above photo.
What Hersh is trying to do is irrelevant to the facts. Pierre Salinger thought a missile shot down TWA Flight 800. It didn't make it any more plausible.
I won't deny that humans lie and therein lies the problem. How do you get so many people to tell the same lie, and then stick to the story?
Bin Laden could be living in a condo in Fort Lauderdale. Why not? There are many possible scenarios which show this to be possible.
If this story is true, there will be a thousand details which will confirm it, things far beyond the control of the most powerful conspirators. Of course, Bin Laden may have been shot by a gunman on the grassy knoll.
