The German state has been under reporting crimes by by its stupendous numbers of Islamic immigrants for decades.
This is quite deliberate and done to foster an utterly false illusion that these people are integrating.
They are not.
"Bild" reports two German native nationals arrested. No links to Muslims or foreigners. Seems to be a an extreme rightwing attack.
They had planned to gun down a lot of Jews celebrating Yom Kippur in the local synagogue today. Unfortunately for the culprits the entrance door was very well made.
The police is looking for more suspects still on the run.
