It IS beside the point; they are totally unrelated. Police killing unarmed and helpless people no matter what their color is an atrocity and needs to stop. The relative number of people killing each other, again no matter what their color, is a non sequitur.
The police are an arm of the State (I do not mean Illinois) and are therefore required to treat people (once again, no matter what their color) with equanimity and restraint, not only for the sake of the people they encounter directly, but for the sake of those whom take exception to cases like what that arrogant bully of a cop did to George Floyd and for the sake of everyone else who gets caught up in the melee that follows.
No one wants to get rid of all the police; that's a straw man argument. Everyone should want the police to stop abusing their authority.
Sorry for the diversion; I've said my piece.
