A new study has confirmed what you've been thinking about left-wing protesters all along. As far as Berlin goes anyway.
The report, which found 92% of protesters live at home and one third of them are unemployed was published in the German newspaper Bild. Demonstrators arrested for politically-related protests between 2003 and 2013 made up the study.
According to the Washington Free Beacon, the study was conducted from 2003 to 2013 and based on 873 arrestees from that period. The statistics came from the Federal Office for the Protection of the Constitution.
In addition, in 15 percent of cases, the victims of the protesters were right-wing and 80 percent of the victims were police officers.
