Ha. And what did they expect? Rolling around with a flag of a country that invaded another country? These people with Russian and Soviet flags don't deserve any better treatment, separatists who only make the situation worse. We are at the borders of real war because of them, they're not any better than thieves or murderers, separatism is a crime as well, not only in Ukraine but in Russia as well. Everyone here knows what kind of people ride cars with these Russian flags. Maybe you in Russia don't know, but for my city I can tell you: people who really love Russia (i'm okay with that, but they're minority, I personally didn't meet a single one, because they're mostly very old people who still live in Soviet Union), people who got paid for that (well, the vast majority), simple separatists (bastards who hate everything Ukrainian and claim that everyone who likes are fascists), real citizens of Russian Federation (somehow there are a lot of such people in Ukraine who work for Russia here).
Also, these riders are from the other city (more than 100 km away) who got paid to ride there with Russian flags, it's not even a secret for anyone.
