Disproportionate rates of police violence against blacks: Racism? The difference between white immigrants and black people in the USA is that most white people came here voluntarily (more or less) while black people came here as products. This difference created a very, very deep cultural, economic, and social rift.
Yes, Americans are hypocritical (as is the entire human species--it's what we do, it's what we are). Very little was done to undo the racial rift until roughly a century after slavery ended. Since Brown Vs. Board of Education in 1954, a great deal of effort and money has gone into compensatory programs. There are programs in education (like Head Start), health (like Medicaid, food aid), welfare, housing (like HUD), employment (like EEO programs), civil rights legislation, and so on. Many, many billions of dollars have been spent on these programs. But the rift still exists.
Parts of these programs were unsuccessful. Everyone who knows about endemic racism knows how the programs failed (and at the same time ignore the ways in which the programs succeeded).
Police have always had a repressive role with respect to all groups the ruling classes have not liked. Blacks are one of the groups the ruling classes are least fond of, and much of working classes aren't either. Hence, continued discrimination. Some of the discrimination is subtle, some gratuitous, and some egregious.
The hard part about finding solutions is that the black community itself is largely not in a position to do much about it's own situation. They are trapped just as many other communities are or have been trapped. Is this just blaming the victim? As Jesse Jackson once said, if somebody knocks you down, that's their fault. If two weeks later you haven't got up yet, that's your fault. Sometimes that's the problem. At other times a general rejection of white culture closes avenues of advancement. Developing a subculture of strong difference doesn't help either. There's always the problem of insufficient resources, the missing input from previously successful generations, and so on.
None of this is a new crisis, it's an old one which has been addressed again and again for around 65 years. I don't see any new thinking in the current criticisms that suggests the outcomes will be different now than in the past. Sorry deeply sensitive, consciousness raised, anti-racist, anti-sexist, anti-imperialist, etc. thinkers: you're not saying anything new, insightful, or likely to succeed.
