and possibly all of Dallas. Four officers are dead already. http://www.nbcnews.com/storyline/da...cross-u-s-over-police-shootings-black-n605686 I'm not surprised. Every black man I saw on TV today was obviously personally devastated by the events of the last couple of days; as if they have gone beyond anger to despair. It was striking and noticeable even in Obama. He looked so incredibly sad. But I saw this in everyone of color today. Some unstable person or someone on the edge was bound to lash out. Correction, five dead. Late edit: Another correction. I thought one of the suspects in custody had already indicated this is an attack in response to the killing of two black men by police, but we don't know that. I think they were referencing the protest march and I misunderstood.
