• A black immigrant fatally shoots churchgoing white natives.
• He is from Sudan, one of the countries included in Trump’s initial travel ban. That ban, propitiously enough, expired today, on the very day of the shooting. The new ban added Chad, North Korea, and Venezuela but dropped Sudan. Maybe we put Sudan (both of them) back on the list, Mr. President?
• His Facebook cover photo shows a black man taking a knee. The man turns out to be the shooter himself in the gym, but it was presumably cropped to show support for the kneelers (his feed is full of pictures of himself striking muscular poses, so it’s not implausible that steroids or some other enhancers played a role).
• Samson’s murder spree is cut short by someone running to his vehicle to grab his gun and then exercise his Second Amendment right to hold Samson down until police arrived.
• He refers to Africa as "the Mother Land" (imagine if Roof had referred to Germany as "The Fatherland").
• He shared this colorful clip exhorting blacks to raise young warriors to prepare for the coming fight for independence.
• He supports all white-owned land in South Africa being seized reclaimed from whites and given returned to blacks.
You get the idea.
Who? Whom? dictates that, far from spurring any sort of national movement against black-on-white violence, this incident will be flushed down the memory hole by week’s end.
