Except Strelkov and his stooges already admitted to shooting it down, albeit they thought it was a Ukrainian transport carrier. Strelkov also admitted that the recordings from the Ukrainian SBU are real, he just claims he was "taken out of context" when talking to his Russkie handler.
Maybe Strelkov, a Russian GRU, is a double agent working for NATO?
...or maybe you're just regurgitating talking points from the Clinton/Kerry State Dept. with whom you share an agenda.
