The article discussed shows that dis-proportionality might be explained by wealth. Poor people are more likely to experience a police violence. And black person are more likely to be poor. As I understand, if you controlled for wealth, when calculating rates, you'd get the same rates for black and white. In contrast, articles linked by you are examples of "journalistic research" where people who cannot into statistics just mechanically use some primitive statistic tools, get some numbers, and jumped to a causal explanations without a second thought about validity of their conclusions. But correlation is not causation. Children with bigger feet could read better. It is correlation, but there is no causation, big feet do not help to read. I repeat, I do not entirely convinced by that correlation with wealth, but it seems as a plausible explanation. While pointing to some correlation and jumping to conclusions do not seems like a good way to find roots of a social problem.
