A shame there's not more information about the incident.
I checked some German sources and this is what I found: The protest camp was build two weeks ago, before the "Palästina-Kongress", which was cut short because they had someone hold speeches who's banned from political activity in Germany for antisemitism and glorification of violence. The protest camp was allowed to stay because they didn't break any rules. Over the next two weeks several incidents started to accumulate, which were deemed increasingly criminally relevant. Planted areas were damaged, streets were blocked, passerbys harrassed, police attacked, antisemitic paroles and incitements were shouted. A court issued a ban on the camp and friday morning police announced this, at which time most protesters removed their tents and left. The few remaining stayed until 4pm when police decided to dissolve the camp, which some protesters didn't want to accept. This moment is most likely what we see in the video.
I know some people out there got the impression that Germany simply arrests anyone who's not unapologetically pro israel in this war. I myself would want our politicians to be more openly critical of israel, although I think I understand why they struggle to do so. Based on what I see in the news and the political opinions of the people around me (which are mostly pro Palestinians, anti Hamas, anti Netanyahu, pro Israelis) I do feel like the people on lemmy seeing this as examples of facism in Germany only see a very limited part of the picture. Videos like this with no context whatsoever are not exactly helping there, either.
If you want to see facism in Germany look at the AfD, our most right wing party. Their lead cancicate for the EU-parliament recently received 20k from Russia to spy for them (which obviously doesn't stop the party from endorcing him). Their position on Israel is nonexistent. Israel doesn't like them (since they're Nazis) and they, by policy, don't care about other countries at all ("Germany first"). If there's ever a return to facism in Germany, those are the ones that will do it.
This is the exact shit people were saying for the Hong Kong protests, and the exact shit people were saying for the Tiananmen Square protests. Word for fucking word.
