Chronic problem
Anti-immigrant sentiments are not new in Germany. Conspiracy theorists, neo-Nazis and gun enthusiasts, known as "Reichsbuerger", or "Citizens of the Reich" are still a threat to the modern democratic state.
One of those, identified only as Wolfgang P., shot a policeman dead during a raid in 2016. He goes on trial on Tuesday.
