The most likely reason for the sudden demise of this Putin-slandering opportunity is that the Russians have a link between the assassins and some entities in or near Washington DC. The Russians are way too shrewd to publicize this, they prefer to keep it up their sleeve like an ace for use if the western mob oversteps its limits there in Russia´s back yard.
You are not wrong there. One hint that was slipped by the investigation committee is that they have evidence that the Ukrainian model took an active part in the murder, having a second mobile, which she dumped, and which contained a tracking device. I guess there is much more that was left unsaid.
I´m sure there is. Well, it was pretty blatant, whacking the guy right there next to the Kremlin. Maybe it was also supposed to be a message, watch out Vlad this is how close we can get, that sort of thing. When western neocons and Ukrainian neonazis plus the accompanying screwballs and spooks put their heads together expect all sorts of craziness, that´s for sure. Good luck, g
