So this is the Berlin agency of internal affairs trying to expel four people for using the forbidden slogan “from the river to the sea”, for blocking a street in pro-Palestinian protest, and for making (unspecified) anti-semitic statements. The agency also claims the ‘defendants’ were supporters of Hamas. (I put ‘defendants’ in quotes because they are not legally charged with anything.)
Even the Berlin foreigners’ agency says expelling these individuals is not legally justifiable. Three of them are EU citizens are are therefore free to roam anywhere in the EU.

More like one agency in one state in Germany (Berlin acts as a city/municipality and as a state in Germany), in addition to being the capital of Germany.
