You can’t really look at crimes committed by Black people in isolation because it’s so greatly affected by how society treats Black people general. It would be surprising if they didn’t commit more crimes. It seems like any group which is systematically oppressed, segregated, ostracized, and denied access to most resources would engage in more criminal activity. It has nothing to do with any trait inherent to Black people. Rather, it has everything to do with how white society has treated Black people.
Imagine if there was a stereotype that white dogs were more aggressive. People would then react as if white dogs were more aggressive and be more fearful of them, reject them more often, throw things at them, etc. And then–surprise, surprise–white dogs would actually act more aggressively. But it would have nothing to do with any inherent aggressiveness of white dogs. White dogs are born just as friendly as any other dog. But because of the way people treat white dogs, it creates an environment where white dogs are treated in a way which fosters and amplifies aggressiveness. In this scenario, there would be all kinds of stats where white dogs are more likely to be strays, get into trouble, bite people more often than other dogs, etc. While all that may be true, none of it is inherently due to the whiteness of the dog. Rather, it’s all due to the way that the society treats dogs with white fur. If the society treated white dogs like all other dogs, the behavior of white dogs would not be any different than any other dog.
