I was in the UK at the time of the 'riots' a few years back, I went out into the street to have look and most of them were black. The mood among the crowds was more like a party mood, no slogans or messages, like a night out. I overheard a young black woman walking past me with male friends saying they should go to a jewelry store next, forgot the name but it's a popular local UK franchise.
Not matter what the media or propaganda says, I saw it for myself, people starting fires, smashing windows, burning cars, robbing and crashing a bus and then setting it on fire. 90% of them were black, the 'riots' were just an excuse to steal stuff and damage property.
