I guess I was just objecting to the idea that "racism" is the cause for these statistical imbalances, especially since you see the same kind of thing happening in Europe which would seem, at least on the surface, to have less racism issues, no? But perhaps I'm wrong since a lot of good people think the opposite, but it's hard to tell since it's so politicized and sensitive, just like anything about race.
A reasonable reader might suspect that you reached, for whatever reason, the conclusion that capital punishment couldn't be racist (perhaps because, as you've stated in other comments on HN, you feel the term "racism" is used too often), and are now intent on working your way backwards from that conclusion.
I think you should take a beat and reconsider how you're approaching the topic. It's an odd experience discussing this with you and watching you do little dances after each response to reorient yourself towards your preferred conclusion.
Edited extensively from the one-liner I originally wrote, sorry.
Do you have any suggestions on straight, fact-based reading on the subject, sources that aren't trying to appear sensitive? It's hard - even admitting races and may have differences upsets people.
On Norway, I'm just saying they don't have the same levels of racism baggage as the US regarding "Africans" (quotes cause it seems weird that many of them have families in the US longer than mine, but I would get no qualifiers as an American) yet still Norway sees overrepresentation.
There's a scale from accident, via involuntary manslaugher to murder. There may well be bias in judging what to prosecute.
Also, laws such "three strikes you are out" may lead to more murders. If, say, you're a burglar with two strikes, and a house owner wakes up and recognizes you, hitting him hard out of fear for that third strike becomes more likely. Similarly, racial bias by the police may make people so wary of "he said, she said" situations that they will 'snap' and kill someone instead (IMO, many people convicted for murder aren't cold-blooded killers, but mentally not the most stable persons who have been dealt a socially unfavorable card in life)
