Time to re-think German and European immigration policies?
Not really, although that is what right-wing people want to make you believe now. (including widely circulating the image of a black man supposedly attacking a white woman that can be traced to posts from Spanish media first occurring in 2010, claiming that it is what occurred in Germany in 2015)
Why? Yes, if you look at the horrible occurrences in Cologne, there were about 1000 men there, many of them of North African / Arab Origin, many of them drunk and aggressive, and throwing fireworks. (This, however, is not so uncommon at New Years Eve in most German cities, I have to say
)
However, according to the police, the acts of sexual violence - that undoubtedly were horrible and need to be investigated and punished with all severity - were committed by an estimated 80-100 organized criminals (also of North African / Arab Origin) that are obviously known to the police as "intensive criminals" and have been in Germany for a longer time. They likely used their horrible sexual assaults on women as a means of intimidation of their victims and to cover acts of theft / robbery.
So yes, it is a horrible occurrence that needs to be punished, but it is not a reason to re-think German and European immigration policies (as the perpetrators were not refugees, but organized criminals, according to the police).
It also became clear that the police were not prepared at all and were critically understaffed.
*** Update *** .... however, there are also first messages on some German media, that policemen supposedly anonymously commented to the media that there were many asylum seekers among the people they had checked on New Years eve. It is - to me - however unclear whether "getting checked by the police" is the same as having committed an offence, and I am also waiting to hear more confirmation of that.
I do not believe that the German police can and would suppress evidence they have that implicated refugees. From what I know, they are now analyzing the video footage of surveillance cameras in order to identify the perpetrators.
