Not enough people have questioned the very poor quality images and videos that were force fed to the world at the beginning of this saga.
Debunk those images such as the Paris Match "photos" and there is no case against Russia or separatists but what is even more worrying is that if those images and videos are proved fake then due to the rapid timeframe of them appearing that begs the question of were they prepared in advance of a premeditated attack on a civilian airliner?
For instance Paris Match announced their journalists were on hand to capture the photograph of the BUK on it's way from Donetsk.
In my opinion the Paris Match photos are video grabs from a dash cam , probably of the Volvo pulling a digger or some other machine and then the BUK was badly photoshopped on hence the weird angle of the BUK, it appears to be perched up on it's front wheels whilst the tractor unit is flat to the road.
