and would be interested in some of the statistics behind some of it, I don't quite get the same numbers as you do from my research, albeit still quite high.

Homicides don't necessarily equate to all crime, and it could be in other areas, where issues around reporting of crime, investigations etc could lend to a skew, whereas homicide is generally more cut and dry.

I could be conflating racism vs bigotry myself, and if power is part of racism, then i might be thinking more of bigotry, but to your point around class vs race being the issue, as long as there is a reasonable amount of bigotry, then I think there could be issues in trying to get more blacks out of the poorer classes. I think that as they have to try harder to overcome the bigotry, when other races don't, this does put them on the back foot making it harder to succeed.

Regarding the crime stuff, what I had seen, albeit haven't seen the stuff behind it to back it up, suggests that for the same crime, black people tended to serve more time than white people.

I do think that looting / burning shouldn't be tolerated, but just because there are criminals hiding behind the protesters doesn't mean to my mind that the protests should stop as such. And there have been a lot of peaceful protesters and media that seem to have been treated as criminals unnecessarily, but this point to racism as much as a presence of police brutality.
