I remember being horrified at the videos on Twitter before the England Russia game, was absolute carnage.
So one video that was horrific where a black Frenchman was stood with his shopping bags watching the carnage unfold on a side street with the England fans in the background further up the street, and this stocky Russian who was nearby walked past him then walked back and knocked him spark out in a punch and seeing his body unconscious with his legs twitching, took almost a minute before some locals went to his aid.
