Well, I was thinking about that. If it is coordinated by some shit like KKK, well, I dare to say that this is good in a sense, because it would be dumb as it gets, and it means that those motherfuckers are going down -- there is no way in today's world that they would get away with that. Simply no way. (so, to be clear, the "good" part is that I think that, if this is true, this leads to those guys going down, the "going down" is the good part, not the death of a person).
What I disagree is that this is coordinated on a police scale, or in a larger political extent. That is the position that I find counter productive. Look, I live in a country where this kind of thing happens too. Just last week a 14 year old boy was shot by the police inside his home, by an assault weapon. The whole group were all surrendered already, smaller children were close, his mother was close. He was shot in the back (where did that happen? In Rio obviously). You guessed right the skin color.
But what do you think that happens if you let a heavily armed, underpayed, untrained and corrupt police force acting in a heavily populated area, with a insane crime rate, and a huge racial social-economical disparity? You don't need coordinated efforts for shit to happen. Actually, you need a miracle everyday for shit not to happen.
