tbf, the report quoted is from North West Rhinefeld, and Hamburg is in a different region, so wouldn't have been included in that report, but the WSWS article should have included other places too, I've lost track of all the places this happened. Have you got a link for the number of attacks in Hamburg? Struggling to find anything concrete,
daily mail article from the 25th says 200 complaints of robbery and sexual assualt.
Bielefeld, where does your 500 number come from?
Telegraph has police saying 150 and the only places I can see saying 500 are loony right wing sites like Pamela Geller's.
Not that the smaller numbers make much difference really but I like to be accurate - and it may change eg police response I suppose. Also I can find it much easier to imagine 150 people in a criminal organisation working together to do this than 500.
