'Posted on this years ago - it seemed a slam dunk and had too many coincidences to be an accident.
I mean come on...the president of a nation which broke away from Russia, who openly opposes the current Russian leader vigorously and that ruthless Russian Mafia-affiliated oligarch used to run the Komitet Gosudrarstvennoy Bezopeznasti (KGB)!?!
Then the Russian government does the post-crash investigation, vigorously exclude any other entities from doing the same and then (surprise surprise) give themselves the "thumbs up" on any involvement !?! Sure. Fine. Right.
It's ridiculously easy to force people to do things like kill someone else if you have the money, the motive and the means. The Russian Mafia is among the most effective organizations in the world for compelling people to do just that for them - and in such a way that there will be little or no evidence of the true motivation or players behind the scenes.
Just offhand I can think of at least four or five ways that someone with the power to crash that plane could be compelled to do so in such a way that no evidence remained of their action or why they did it, even if they were caught or blabbed to the international press about it.
