Obama did the same thing, taking a blind eye when the Black  Gorillas( re-branded Black Panthers),  patroled and stood guard at polling booths in the south , or failed to make comments about Black Lives Matter movent calling for "pigs in the blanket call". Yeah, blame Trump and his support base, but it started before him. Obama did the same thing. White people see an opportunity to get even and most us didn't care enough to vote. Couple that with police afraid of over-reacting (Post Ferguson policing), expect more events like this. I think Chicago is ready to explode, blacks moving violence out of the housing areas into the city,  their way of getting even.
