She claims that “she’s not at a protest so it can’t be an illegal one”, meanwhile, back at the taz, she says it was a protest (“Kundgebung”). It might be an odd interaction but then you can also try and politicise the hell out of a cop tangling you up in a discussion and asking your for ID – which btw they can do without any reason at all. The whole thing was over in 30 minutes, no arrest (in the legal sense). Berlin police at that time was very much on edge as in previous years they had to deal with massive violence during the Nakhba protests. There were permitted demonstrations, she could’ve gone to those. You can then also say “but she’s a Jew who’s holding that sign getting tangled up in a discussion with a cop, this is triply outrageous!” – why should there be different laws for Jews and Muslims? It’s all applied equally. That not being the case would be triply outrageous.
I assume the rest of your wall of text is in just as good faith so I won’t bother.
