Tire burning is not really large scale destruction. From the livejournal entry:
1."They destroyed the whole city"
Not true. All of the action you see in the pictures are happening on a small square near the entrance to a Dinamo stadium. This is a government sector, there is no intereference in peaceful life outside of this area. If you make an analogy with Moscow, imagine that the barricades are someone in the area of Ilinka or Varvarka, near the president's administration. Sure, it's the center, but regular Moscovites wouldn't notice. There is dark smoke and fire on all pictures: those are mostly burning tires. There is not tangible damage to the buildings. Unfortunately one store burned down last night near the barricades, resulted from a poorly thrown molotov cocktail. Even the statue of Lobanovsky, located in the epicenter of fighting has been covered with cloth to prevent damage. Overall, the protesters are very careful regarding property. They've take apart fences and benches, but no windows are broken, noone is vandalizing, and all looters are caught and beaten. So the picture is pretty apocalyptic, but things are not so bad.
3. "The entire Kiev is paralyzed, there is no peaceful life for the regular people."
Kiev is living its own life. All stores and cafes are working, people are going to work, study in universities, get married, divorce and even die their own death. Most of the Kiev populace are not inconvenienced. Imagine if Navalny took over the Red Square and set up his camp there. What would change for you, Moscovites? Nothing. So the only people who are inconvenienced are toruists. A few stores and cafes had to close down in the very center. Also, those living in the center have troubles with logistics. But the entire Kiev is not paralyzed.
