And, I guess I could google-up the story about the decades old mass murder of a town of blacks in Florida, or the over-hyped pickup truck chain dragging of a black man in Texas - but I won’t even though your cite was from 1974.
I don’t discount events like this haven’t happened, the racial divide climate Obama has perpetuated certainly has made it much easier. Similarly, the exact location where these atrocities occur can be a factor. I’m just a little more optimistic and probably reflecting on whether the instances in South Africa are much, much higher on a population basis than here in the US.
That said, I won’t sit here and tell you we don’t have a deep deep problem with race in this country and with an administration that fosters this divide every chance they get.
