White folks brandishing guns in the faces of black folks marching for their rights: Indeed, this looks kiiiiiiinda racist and makes for easy dunking material.
The McCloskeys lived on a so-called private street. I assume this lawyer power couple imagined they'd purchased freedom from the world and its problems. Too bad they happened to live on the same street as the St. Louis mayor who took it upon herself to release identifying details of police reform activists at a press conference 2 days prior, which is what touched off this protest.
They'd probably also imbibed propaganda priming them to view any BLM protest as a Molotov cocktail-party waiting to happen.
They were wrong. As it turns out, the vast majority of BLM protests are peaceful and this one was as well: save for their own gun-wielding activities that threw gasoline all over this situation.
Worth noting as well that no other neighbors reacted this way, and indeed 38 of them signed an open letter condemning the McCloskeys for this conduct.
