I dont understand how losing a game can move people to this. As prophet said: "The IQ of a mob is the IQ of its dumbest member divided by the number of mobsters." I mean, there must be a lot better and more justified reasons to start rioting than this! Its just so roman empire like. Panem et Circenses.
Even though the pictures look quite brutal reading the reports I would assume that this wasnt such a big mess. It could be because police where well prepared, but I have a pathologic distrust for order forces effectiveness. So im guessing that there where just a few hundred of violent guys there and a few thousands of cheering observers.
I have read about way more injuries and property damages than what they reported in what news called "violent movements" or "fights for social/civil/worker rights" not so many years ago. I think that we live too apathetically (what we are sold as peacefully).
P.S: In case there are any doubts. I dont aprove this kind of violence and even less for those motives.
