White on white mass shooting is a major crime with at least a weeks news cycle.
White on black mass shooting is a super duper major crime with added penalties for being a hate crime with a minimum of 2 plus weeks news cycle, plus a few riots.
Black on white mass shooting is a major crime with a one day news cycle.
Black on black shooting is just another Saturday Night in Houston. Or any other black controlled city.
Only #2 would get serious news attention. The others would not as they don’t fit a narrative.
If the shooter had been a “cracker supremacist” we would know everything there is to know about this incident including the victims’ shoe styles and sizes.
#2 never happens.
