Well, there’s just to much here to agree with, so instead, to expound on your theme, maybe it would have been better described as “This dark day is yet another white racist incident of violence in a long string of them perpetuated unfairly against black Americans just going about their business.” Some more direct quote by sheriffs or officials would be better to show the unbroken chain of continual events. I very much agree with your view of history here as a continuum of human interactions that are constantly reinforced, not some single incident as it framed to be.
Thanks again.
