Yes, there really was hell in France for a while with billions worth of property destroyed and hundreds of serious injuries.
There were similar conditions in Gothenburg in Sweden a few years back too, one of the only Swedish protests that required police armed with live ammunition in a long while.
The biggest issue here in Norway are foreign "gangs" or mafia starting or continuing turf wars in the major cities. The most prominent being the "A gang" and the "B gang" which are tearing up the streets in Oslo and having shootouts on huge public arenas with big numbers of people on them.
There was also an incident with some Tamil invovling severed limbs, machine pistols and a genuine samurai sword (!).
As an American, I have to admit that I'm found some of the situations in Europe over the past decade comical in a rather morbid way. To hear Europeans up in arms over immigration troubles, to see the rioting, discontent, etc. just made me say "Well shit, now you know what it's like to be in America. People of different cultures just don't magically get along with each other. Took you guys long enough to realize that."
