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."
