they have pretty much narrowed down the area where the missile was fired from; absolutely a separatist controlled area. So that is that.
Now the real question is was it a captured Ukraine system or one the Russians supplied recently.
And who was operating it. Separatists or Russian 'volunteers'
with reports already showing that the accident scene has been disturbed, and the separatists interfering, there is no way this will ever be considered a clean investigation.
But I think more than enough will be shown to point the finger right at them and Putin as being responsible.
Sadly I do not see the leadership or iron in the spine in the west to really make Russia and above all Putin pay.
