Pfft. It's Europe. Riots are nothing more than a beloved sport over there.
I shit you not, Europe's love of rioting is one of the most common things I hear from conservatives in America who hate liberal ideas where I live. I'm neither so I end up playing all fences and see everyone's different views, and I hear way more details about European rioting than I see on TV. Usually links to YouTube and Twitter feeds and crap and it drives me up the wall.
I have never heard of something like that! It's true we have hooligans who occasionally riot for fun / as an outlet for aggression, but regular riots are hardly a European thing. I think it's more true that the US has few riots. But you guys have more mass shootings in a month than Europe has (not-soccer-related) riots in a year.
2011, when people made off with mad swag and certainly didn't implicate themselves on social media for later arrest.
