Again, how is that relevant? Are you saying that black people somehow deserve no protection by police because "they should get their house in order" first? (Whatever that should mean)
You bring up a good point: far more black people are killed by other black people than are killed by cops (white or black). But we don't hear about it, demonstrations are rare and news is non-existent.
It would be a significant improvement if black people quit killing their own. And it would save far, far more lives than were all police to never kill another black person. But it is completely the responsibility of blacks to quit killing other blacks.
It is worse than that: black people murder more than ten times more black people than all white people murder black people:
