Questions were not about Maidan, which indeed got ugly. Rather - can you see the same ugliness happening in ... Paris? London? Riot control forced stripping and killing protesters? Using live ammo?
A protest isnt a riot, and a riot isnt a revolt. Where we draw the line is totally up to interpretation : trust the demo to deem themselves peaceful protesters whatever happens, while the government will treat them as dangerous rebels day 1.
But a siege with violence and destruction where the people numbers by the tens of thousands and took control of parts/totality of one or more cities, is a revolt to me.
You can bet your ass that whether you're in Paris or in London or wherever, the government will defend itself tooth and nail.
Live ammo taboo works only until a point, thinking western countries are never going to use force in the same context is naive at best, at worst propagandist.
