I know it isn’t the main thrust of the post but I still see that no one has cited Russia actually acknowledging (even through an unnamed source) pulling the trigger on Litvinenko, or even making the Polonium. This doesn’t mean they didn’t do it; it means they are probably stonefacing / stonewalling. This is far more typical as these sorts of things go, and that’s why I was surprised Wretchard claimed otherwise. I suspect Wretchard misread the attribution and thought an unnamed UK source was a Russian one.
