Politics: Coup d'Etat in Germany

I think the recent arrests of so called "Reichbergers" (but they are not Reichbergers) Terrorists in Germany is a joke and an embarrassing wishful career move by the German Prosecutor. Using 30000 police officers and swat teams to search 130 properties and arrest 25 people is a total overkill. And then the usual narrative... they are Russian linked.
Would anybody in their right mind attempt a Coup in Germany with 25 men?
