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.

Why was Floyd pinned to the ground until he suffocated when all he supposedly did was use a fake $20 bill? (supposedly because innocent until proven guilty). Why did none of the other officers present step in? All of them are guilty IMO.
As a police officer, you need to keep your colleagues in check. The problem right now is that there's vast groups of policemen who have no qualms with using excessive violence, especially against PoC, and they protect each other. I suspect that goes up the chain of command all the way up. For one, the US President himself hasn't condemned the actions of the police, not in the Floyd case, not in any other case of police violence. And that makes them complicit.
