The cops actually claimed to prevent antisemitism by clamping down on hate speech. BTW, they, among other things, did that by laughing at Jews with quippahs in Palestine colors who were present at the congress. The cops also later admitted that there was no case of hate speech at the conference. But surely there would have been one if it would have gone on for the planned three days instead of the actual two hours after which it was shut down, i can't imagine German cops being in the same room with a bunch of leftists and Arabs for three days without the cops using any slurs.

I mean, the police spokesmodel charged with disseminating German state agitprop?

Or the random chud cop running around in ten tons of tacti-cool SWAT gear?

You'd get some bullshit about the Palestinian Conference being a hotbed of terrorism and extremism that threatens Germany's national security from the former. You might even get some memelord-inspired claims about actual Hamas Terror Fighters being in attendance or a rumor of bomb making material on site.

From the latter? I imagine the best you'd get was "They were breaking the law" and "Listen, we're just doing our jobs to try and keep you safe."
