Main point here is, 1000 'men'collectively sort out women to assault.
The authorites were slow to react also the media,
Then there has been statements claiming they can't police it, so women will just have to fend for themselves.
These are the major issues, as pp have pointed out the German laws already in place about sexual assault are crap and need addressing.
In a way it doesn't matter what culture the perpetrators come from, everyone needs to live by the laws of the country they live in, and that country needs to be able to uphold those laws and protect there citizens.
What ever the cause of this on New Years Eve, it should not be allowed to happen again.
If in fact that means analysing in more detail the circumstances and majority of people involved, to find a way of preventing it in future, then so be it.
But also there needs to be stricter laws on sexual assault in the first place.
