>If someone in disfavor was killed, everybody would still know that it wasn't some random "criminal organization" that did it.
If Skripal had been shot, it would be difficult to be sure that his death had been ordered by the Russian government. In that scenario, anyone with a grievance against him might have done it.
>There just wouldn't be direct "evidence".
Yes, that's the point!
>That's the problem with people watching too much movies like "The Dark Knight" where supervillains do anything just to provoke, and then apply this to states which have tons to lose, and don't just provoke for the sake of it (or to scare some third grade targets, as if they couldn't achieve it otherwise).
Nonsense. I'm just inferring from Russia's previous actions. In particular, the Litvinenko murder, which could equally well have been carried out using more conventional means.
