One of the sentences ("one of the members of the Saudi hit team made five calls from the consulate that day--four to the head of MbS's office and one to the United States") caught my attention. I haven't seen this report anywhere else, but if there was such a call to the US, who might have been the recipient? What did s/he know, and when did s/he know it?
JE comments: It would definitely be possible to find out who received the call. All that is needed is the political will to do so (a tall order).
Meanwhile, WAISer John Heelan forwards this on the Kingdom's "fall guy" for the murder: the (now former) royal adviser, Saud al-Qahtani. He allegedly directed the hit via Skype. Were they trying to save money on international phone calls?
