Black lives matter. Blacks are far more often subjected to severe police misconduct. But not just blacks. That fact gets lost. As also the fact that the black community is primed to respond, as other communities are not.
Whites, too, can be cut down, without provocation, by cop, as this NY Times piece suggests:
And I'd like to refer back — since I'd prefer we not forget — to Gary Busch, nice Jewish guy in Boro Park Brooklyn, slaughtered by police in broad daylight. Some of the eyewitnesses said it was police execution. The officers surrounded this helpless man, counted down, fired.
Mostly, but not just blacks.
