I actually think the issues with cops and violence are likely not race specific. I believe there are other factors it just so happens Blacks are more likely to live in places where those factors exist. Neighborhoods that cops perceive as dangerous. They have meetings warn each other to be careful and then they go out on patrol and are jumpy and paranoid. Black on black violence in some of those neighborhoods doesn't help. However, I do not think it has to do with RACE but purely the violence OR perhaps hyped up violence in those areas that make people more paranoid. That would explain why black and latino cops have the statistics you are referring to.
