If you look at the history of massacres of protestors, specifically in the continent of Africa, often times the people doing the shooting are not fellow country men, a lot less people are killed, or not by small arms fire, by comparison this is a real bad one, which is why I responded such.

If you consider the psychological impacts of having to shoot people in front of you, specifically your members of your own “tribe”, although I know there are long standing imperial divisions in countries like Tanzania.
