Regarding that story, two possibilities:
1. Svoboda are trying to show how tough they are and regain the standing the lost in these protests. (The protests are largely a ship that sailed without them, and they’ve even embarrassed themselves by getting caught in lies exaggerating their activity: http://romaninukraine.com/wounded-maidan-protesters-vs-svoboda-party/.)
2. These are Russian sponsored provocateurs.
I hadn’t heard of this guy or this incident before until an American colleague asked me about them, so I just checked with a friend (thanks, Andriy!). It seems nobody is giving it much attention b/c the guy was corrupted thief who would have eventually been fired anyway.
