For black on black crime or police assassinations, in what ways do they make you feel the same or different?
Since I cannot reply and you flagged because your world view now has internal doubts and you need time to settle down and contemplate these new thoughts...
A police officer killing a black person, is a smaller subset of the racial injustices. For example, why does black on black crime happen, why is it strongly geographically correlated to poverty and police brutality, why do we not talk about it when it accounts for more homicides than the police against minorities, how are retaliatory killings for police brutality not related to the discussion?
In what way is asking these questions changing the subject? Is it rather an attempt to enrich the conversation's context to move away from biased and blanket statements?
The answers highly depend on your willingness to open your mind.
