I assure you, at the very least, the crowd of people that were fired upon randomly in the middle of the day are outraged. As are those who know them, others nearby, and I didn't detect glee from the authors of that article either.
Outrage at intra-racial violence and outrage at police violence are not mutually exclusive. Black people can, and do, care about both and need not choose one or the other.
If we're talking about the sum of black on black crime, somewhere around 50% of the people involved are victims. Those people care, and all of those people are black. That alone should be enough to stop people from making the absurd statement that black people do not care about black violence.
Yet despite that, and being demonstrably false, the idea continues. That kind of deflection happens whenever race is brought up. Bring up minority poverty, someone else brings up welfare fraud. Bring up educational inequality someone else brings up how unfair affirmative action is.
