Wtf. This breaks down to: “I’m arresting you because I don’t understand what you’re saying”

Not, “you’ve said something illegal”, nor any actual crime in any form. Arrested purely because the cops don’t speak the same language.

So If I don’t speak English/German, I’m not allowed to represent my opinions and values, nor support those that do?

We also aren’t talking about some totally unexpected language like idk, Belarusian. It’s Irish, while protesting infront of the Irish embassy… If the cops don’t understand, that’s on them
