parading prisoners through main square - a great example of a country you all russophiles would love to live in 
You'd prefer them to be executed like Ukrainian "oligarch battalions" usually do with their POWs?
Anyway. It was just a convenient reminiscence to Moscow event in 1944, and a message to Kiev. No one was hurt or beaten: few insults, hurdled eggs and rotten tomatoes can be hardly compared to hundreds of civilians killed or crippled by indiscriminative shelling of cities by Ukrainian forces. Yeah, let's start a drama about this harmless parade, while pretending that we're not seeing war crimes and huge humanitarian catastrophy caused by Kiev
P.S. updated map of situation in ATO region: http://img.pravda.com.ua/files/d/d/dd1ad30-25-08.jpg
That map is just ridiculous. It is showing situation as it was like a month or two ago, and even then it was way too optimistic for Ukrainian side. If you want to know what is really going on instead of reading propaganda bullshit, check: http://militarymaps.info/
