I doubt Yanukovich expected these protests and what they would lead to.
So yes, the protests started suddenly.
"...A 100 protestors died. Shot mostly by police..." Many police died as well. Shot and burned alive with molotov cocktails. This is irrelevant. You're admitting the fact that there war violence.
So yes, violent.
"...Yep, the constituional issue created only came about because..." This is a justification of unlawful illegal actions, nothing more. Doesn't change the fact that Yanukovich's ousting was unconstitutional.
Unlawful.
Sudden, violent, unlawful seizure of power from a government. Definition of a coup. It was a coup.
