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.

That said: it's increasingly evident that they're very poorly trained. You see the same strongman tactics in every city. They gang up on a single person, sometimes 4 or 5 of them, all hitting, all kicking, and continue to do this once you're on the ground. If you've ever watched Live PD, you see a ton of this same behavior, all the time, all across the country.
At the same time, there are some really bad cops out there (and the cynic in me tells me they're more common than we're lead on to believe), and also lots that just don't have the mental fortitude to do the work, but are still doing it anyway. Those people need to be weeded out, and we need to better equip them with tools that are not weapons.
