If the quality of the 'evidence' revealed at the press conference, after two years of research, analysis and compilation, and not even incorporating primary material from Russia, was any indication of the 'JIT' investigation itself, then no one should have any confidence in it.
It appeared much more akin to a PR travesty or Kangaroo Court, that had decided on the judgement without the accused being represented or indeed guilt being established.
Any case that appeared to rest solely on claimed 'intercepted' conversations (that of course could have been faked), unidentified witnesses, modified photographs 'to prevent the locations being identified', mock-up 'reconstructions' and routes, unrevealed US satellite sources, pictures of geometrical scorched and partially ploughed fields, incomplete reconstruction of the plane itself, and many explanations left unresolved, is not worthy of the name of 'forensic investigation'.
To say that one hundred responsible persons had been identified, but be unable to provide a reliable indication of ultimate responsibility, only added insult to injury.
The whole thing was a sham - and a pretty amateurish one at that - that all the uniforms and flags and medals could only emphasise.
