but I thought you were "moving on."
They mention the total number of killings since 1993 without saying "of black people," seemingly as a way of framing what's to come in the video. Tangential, but not incorrect. You saw it that way though, and clearly had a bone to pick with overzealous protesting youth, so carry on.
If that counts as incorrect outright, then consider editing your initial post:
since that's misinformation. Again, I assumed you weren't making up/misinterpreting info with your posts, and I was genuinely interested in what your point was.
Now that your point is more clear: consider avoiding propping up prison statistics in lieu of data of people killed by police when you don't have it
And consider that the UK Black Lives Matter movement isn't just an imitation of the US Black Lives Matter movement, meaning it isn't solely about killings by police. Not that understanding that would change your mind overall, but it'd be a start. Cheers.
