A major deceit?

So claims Seymour M. Hersh, regarding the assassination of Osama bin Laden. Writing for the London Review of Books (paywall):

This spring I contacted [Asad] Durrani [former head of ISI] and told him in detail what I had learned about the bin Laden assault from American sources: that bin Laden had been a prisoner of the ISI at the Abbottabad compound since 2006; that Kayani and Pasha knew of the raid in advance and had made sure that the two helicopters delivering the Seals to Abbottabad could cross Pakistani airspace without triggering any alarms; that the CIA did not learn of bin Laden’s whereabouts by tracking his couriers, as the White House has claimed since May 2011, but from a former senior Pakistani intelligence officer who betrayed the secret in return for much of the $25 million reward offered by the US, and that, while Obama did order the raid and the Seal team did carry it out, many other aspects of the administration’s account were false.

Durrani’s reply:

There will be some negative political comment and some anger, but people like to be told the truth, and what you’ve told me is essentially what I have heard from former colleagues who have been on a fact-finding mission since this episode.

Vox‘s Max Fisher begs to differ with Hersh.
