One thing that is easy to forget is, the USA is a very large place and social and moral norms vary to an incredible degree, perhaps more than any other country in the world. I live in a pretty conservative part of the nation and often hear people gasping with surprise at what happens in New York and California. Likewise, I have heard people from those places carrying on about what happens here. Unfortunately, what usually results is that we end up proclaiming each other to be ignorant/backwards/evil/barbarians and so on. Everyone thinks that only him/herself and similar folks occupy the moral high ground and everyone else is scum.
Yeah, I was a bit surprised how quickly and, should I say easily, that policemen who killed George Floyd was convicted and even his team mates who more or less did nothing. Court's proficiency was a bit out of kilter because courts in US routinely take side of police.
And then I found this:
After George Floyd’s death, pent-up frustrations, provocateurs and inexperienced leadership led to mayhem for three nights.

And that explained how heavily the whole court process was politicised. Basically minorities said "either put that policemen into a prison or we'll burn down the whole country, like we burn Minneapolis."
Essentially, US is going through a huge transition ( like the rest of the world ), where world is becoming significantly more multi-cultural and multi-racial. As far as I can see UK has gone much further down the same line, although much more peacefully.
