One detail of the original video that disturbed me was the "guard" in the yellow vest who was just looking at his phone and pointed at the 3rd body. News interview with his brother today reveals he is a mentally-challenged employee. At least here in Boulder, our groceries are good at hiring folks with disabilities for menial jobs like bagging and moving shopping carts; we have several at my local store. This poor guy was described as severe dyslexic and just had no clue what was going on around him.
