It is not necessarily done by the government. But government might be involved too.
Frankly, the Kremlin's ability to pull the wool over some people's eyes by splitting hairs between active and passive involvement is astounding. Then again, those people aren't very smart to begin with . . . .
You're stupid Russkie. How do non-government entities get massive amounts of military weapons and armor and pass them through Russian controlled border checkpoints?
From the AP, as mentioned on the Interpreter:
AP reporters say convoys of military weaponry and supplies have been coming from the direction of Russia into rebel-held Ukraine. Rebel fighters also described how Russian border guards did nothing to stop them.

Even the separatists admit they are getting aid and soldiers from Russia. They even said a week or so ago that they had received 1,200 soldiers fresh from Russia:
"Pro-Russian separatists announced 1,200 troops and 150 vehicles including tanks trained in Russia will join their increasingly desperate fight against the Ukrainian military. Separatist leader Alexander Zakharchenko, who made the announcement in a video, did not specify the origins of the troops or weapons."

I know Russia is economically somewhere on the level of Africa, but I don't think I can believe that they are such a lawless country that random citizens of Russia are able to conduct military training, get ahold of "150 armored vehicles," and then march them through Russia and into Ukraine, without the government having something to do with it.
You're denials are simply idiotic and slavish.
