As soon as you call the problem "Black on white" crime, you're showing your true colours. The problem isn't "Blacks" or "Whites", it's those who discriminate between them.
In short, there is lots of black crime.
Why?
Because of the shitty socio-economic position they find themselves in due to centuries of subjugation, institutional and social mistreatment. And that happened because of their race. In that way it's a racial issue. White racism. Blacks were for a long time not even classed as human, which is a classic dehumanizing tactic used to view the other as an object to be used rather than respected.
Comparing black crime in the USA to the Israeli occupation of Palestinian territory or to the Belgian initiated ethnic violence in Rwanda is wrong-headed and very prejudicial thinking.
