I don' t think "everyone had that information". I assumed that Saudis would kill political enemies who at least committed certain acts with consequences beforehand, not that they would kill and wrap the body of a prominent person into pieces within hours. I thought the russians had monopoly on remotely killing political enemies like that. What was plausible as a hypothesis, but unproven, is now very real, and it has now placed saudi in the same bucket as putin's russia in the mind of "public opinion".
