All indications are that it's about anarchists . . .by 'x'

Do you have any specific links to confirm this specifically for Frankfurt? I've read articles about the anarchist angle as it related to car-b-q's in Berlin and Hamburg . .. but not for Frankfurt. I'll check into the Friedensreich Hundertwasser, and Praunheim topics as time permits. Thanks.

I haven't heard anything specific about Frankfurt, though those districts didn't sound very ethnic from what I've been able to find out online.

When I was over there, Frankfurt had a reputation as a big drugs-and-crime city.
