In DC, there was a suspicious spate of random attacks supposedly committed by violent, highly coordinated Black youths. I don’t think all of the victims were targets of the knock out game, which is obviously a racist myth (there’s no confirmed evidence of the game’s existence beyond accusations from police and prosecutors) but rather the government/corporations. Maybe some fell victim to random street violence, though. But I wouldn’t be surprised if corporate and defense interests paid poor kids from juvie to rough up whistle blowers.
