Another thing to consider.
Actually the shooter was a member of a white nationalist group and attended at least one of their paramilitary training sessions.
& folks would push for ways to stop it (& tying it to black lives matter)
So "What does race have to do with this?"
It's like the national strain of genetic encoding that causes people to have something like Tourette's syndrome.
He was exposed to, received training from and was influenced by aspiring racial terrorists...how could that not influence his choice to lash out violently.
