//What in particular about the ONS's Crime Survey don't you like?//
Haven't seen it, but understand the devices used to adumbrate rather than enlighten.
You firstly need a definition of crime which separates the serious and the trivial and can understand a gradation betwose extremes.
That[i bit which is both common and moral sense is absent.
Let's look at Germany. According to official statistics crime rates in Germany are falling [i]despite[i] (as racists like AfD and VE might put it) the importation of at least one million single young Muslim men in 2014.
For the sake of argument I believe the German stats, OK?. But now I look at specific instances. And I cite Cologne (not the only German city, by the way) New Year's Eve when 1,500 German women shared in the culturally enriching experience of the North African Muslim practice of taharrush gamea whereby crowds of men surround a lone women, grope, rape, or steal from her.
So now we have a novel category of crime which has produced 1.500 victims in one German city. So, for the stats to work in any convincing way, then there have to be at least 1,500 [i]fewer] victims of crime in Cologne since the immigrants arrived than there were before. So for every girl surrounded by twenty Syrian, Afghan, Somali refugees on New Year's Night then there has to be at least one Cologne citizen who had been spared a similar trauma. Do you have any theories about these averted traumas?
