Do you not think that the black community itself doesn't have real problems that go beyond the police? Because it's pretty obvious that they do. Almost every black child is raised in a single parent household. The results are disasterous. Criminality, teen pregnancy, school drop out rates, poverty, STI rates, rates of risky behavior in general, low empathy... all very highly correlated to single parenthood.
Most black people are killed by other black people. Most white people are killed by other white people. Most hispanics are killed by other hispanics. Asians tend to have ridiculously low rates of violence and crime in general, but as far as murder is concerned it's the same situation. Also tend to be more successful in general (higher average income, more likely to attend post secondary etc.). They're not white, what advantage do they have? They also dealt with some pretty serious persecution as well.
