Not all black folk like what some do in Baltimore. I don’t know where the video is, but below you find a link for hundreds of Baltimore riot photos. The ones at top are for the most recent ones, but further down, start looking for the black mother dressed in yellow, smacking her son and dragging him out of that mess and chasing him home. I believe this is the one you mean. I counted a dozen photos before I got to the bottom and had not pushed the spot for “show more.” On the other hand near the top there is the black guy throwing a fence section wearing a black shirt with “black lives matter.” What a bad advertisement he is.
I was speaking in nation wide terms. It's why I said Baltimore etc. See link in 43. She talks of Ferguson and basically everywhere this happens like Chicago etc.
