SampanViking, you may confront your theory with what's here: (google-translate should work; a Czech eye-witness (somebody who was in Odessa on May 2) confirms the pictures are authentic, he's taken similar by himself -- this discomforted some people on a Czech leftist server heheh). You may even tell us if you still think that firearms were used by the members of a protective detail of a local politician ...
Unfortunately Google Translate tells me that your site is a secure site and that translation is not available. This is a shame as the translation would no doubt explained a lot of what I was seeing.
Overall though, the pictures simply reinforced the impression of a sectarian march passing through the community of the other side. Many of those pictures could have been from the Bogside in 69.
I realise you are no doubt trying to call my attention to the few pictures that seem to show men (presumably Russian) bearing what look like semi automatic pistols during the march. Again all we saw were men posing away from the trouble and not even a picture of the weapons being fired, so we cannot even be sure if they are real or replica's.
By contrast there is well publicised footage of Pro Kiev protesters shooting in to the burning Trade Union Building.
As AFB mentions, there are some people wearing some fairly strange archaic gear and the vast majority of the weapons seemed to be sticks, stones and even a few brooms.
Rather more interesting is Mr Putin's announcement today regarding the Donbass Referendum and the May 25th Elections.
This is clearly a plan drawn up with the OSCE for de-escalation and no doubt Mr Putin is looking to use it get back on the front foot in the propaganda war, where he was forced onto the back foot after Geneva.
The reason for that is simple. Despite the continued occupation of Maidan and the continued presence of armed Far Right Militia, none of which Kiev made any effort to disarm or clear, there were far less visible than the Pro Federalisation Gunman and so the West was able to point at their non-compliance and ignore those of the Kiev side.
This time is different as the first step of physical de-escalation will be the withdrawal of the Ukrainian armed forces from the Donetsk region.
It only took 48 hours to kill Geneva, that leaves enough time to put the blame for this round on Kiev and still hold the referendum on Sunday.
