The original reports, including those that were known at the time the press conference was held a few days after New Years Day had the reports of violence around 80, or so, and part of the controversy initially was that the police did not give a full picture of the violence, and had indicated is as being peaceful.
However, much later than this conference, a lot of information has come out and I've seen it reported in articles the number of complaints exceeds 800.
The question of why they didn't shout for help strikes me as terribly cold, and even disgusting. Women being attacked shout for help.
Are you saying you would hear the shouts for help of the women in Cologne, so they didn't shout if you didn't hear them?
If so, did you rush to help her? She was being attacked in true pack-animal fashion. Where were you?
(edit: Alert. The video is very disturbing.)
