Yeah but this isn't Greece. First of all, Greece has tons more of the Black Flag anarchists who always smash and burn things so it's kind of more normal. Plus, just by looking, I think you are seeing a militant communist faction at work. For those guys, it's like they are ideologically trained to look for and exploit any social instability MILITANTLY.

What will touch off rioting in our urban centers will be HUNGER. Cold. Privation. That's still a ways off here.
