It doesn't much matter what you can "buy", the facts are the facts and until Kiev ordered the Ukrainian Army to break up Ukrainian civilian protesters in East Ukraine using deadly force as they saw fit people in Eastern Ukraine were doing exactly what the Kiev Kiddies did in Kiev (other than burning cops alive, that is).
If they armed themselves at that point they had every bit as much right to do so as did the civilians who confronted the BLM in this country. That is, they have the right to use lethal force to defend themselves from a government intent on imposing it's will by the use of lethal force.
What's good for the goose is good for the gander.
I don’t buy the premise that the men in the green uniforms with the weapons are local Ukrainian citizens.
