The story makes it clear Jonah did not deny access to the Zahau experts. Dina's experts obtained access. Time to stop blaming others for their failure to get it done.

Jonah could have required a private security of his choice, to be paid by the Zahau's. Instead he required something IMO that he knew was impossible. He could blame LE, but it is clear that he was the one doing the denying.
Just curious, does anyone know if Jonah required LE to accompany Dina's experts?. If so, and they complied, why wouldn't they also comply with the Zahau's request?
