Now putting myself in the shoes of the protesters: seeing the same destruction, destroying of properties, cars and businesses, I'll call it a day because this is no longer a protest. I'd go back home and wait for this to be taken care of and join a civilized protest once this has been taken care of. A civilized country should be able to hold a civilized protest. And having spent most of my life in eastern Europe, you can say I know a thing or two about protests. Last large protest I was a part of was in ~2013 irrc and the aftermath was very different. The night after each of those protests, everything was spotless clean, people thew all their garbage in the bins, nothing broken or destroyed. People were coming with their children and pets and being completely comfortable with it. There was a completely unrelated incident of a gas explosion at a Chinese restaurant, which burned a nearby shop. People gathered donations fo the shop owner to recover. Incidents with police? Practically none during ~3 months of daily protest. And we are talking eastern Europe - the police officers are anything but the nicest people on the planet.

On the first, I firmly believe that you should always deploy people who are accustomed to a more difficult or dangerous task. Managing large crowds of potentially violent people is far beyond the typical danger police face (usually peaceful, or one or two dangerous people). On the other hand, this is one of the scenarios the National Guard is trained for. And the level of force is likely lower than what they have trained for. The current response is like handingba Sev1 incident to an intern. They're just as or more likely to cause more damage as they are to help.
On the second point, handing armored vehicles and body armor to a group that isn't well versed in their use and effects on the opposing force is a bad idea. The outcome is inevitably the "five foot drop". When you your electronics don't work and you don't know how to fix them, people tend to give it a hard smack to see if that works. Likewise when your day to day policing doesn't work, deploying your heaviest armaments probably seems like a good idea.
I do still hold the officers accountable to a degree. The degree of force is incredibly one sided. However, more than them, I blame the system that put them in a situation they are so unequipped to handle.
