The Cult says they are having 12 000 members . In 2009 they had 5000 - 6000 members said the secret service. The secret service (Verfassungsschutz) sais (in the new report) they are having 4 500 members.
I worked on staff in Berlin for 9 months from May 2007 to February 2008. At that time there were about 100-125 staff members, about half were full-time or full-full time and each month more people went to get moonlighting jobs thus leaving or pulling back from staff hours. There are no more than 200 active members in Berlin, which includes staff and imo less than 1000 active members in Germany.
Sabine Weber also claimed to a German newsapaper a while back that Berlin had 750 members but this is nothing but a bold-faced lie.
