Let me just briefly go over why this is stupid.
They would know this guy Khashoggi was going to be filmed ENTERING THE BUILDING.
The guy was supposed to disappear in THEIR building and never be seen again, which would point the finger right at...who?
Let me tell you how a real hit is done. It's done in a NON-secure location, no cameras, no witnesses.
Despite all the blather about 'audio'! and 'video'! of the supposed killing, nothing has been release. It's all rumor and much of it is likley disinformation.
