You said London and Paris...
https://en.wikipedia.org/wiki/Crime_in_London#Homicide
Number of homicides in 2017 / Homicide Rate / Population (thousands)
London / 118 / 1.3 / 8,825
Berlin[35] / 91 / 2.6 / 3,500
Madrid[35] / 39 / 1.2 / 3,200
Rome (2016)[35] / 21 / 0.7 / 2,900
Amsterdam[35] / 19 / 2.3 / 813
Another thing... Amsterdam with its free drugs is waaaay above European average. I mean, it has
just 60% less murders than USA's average! That is horrific.
Berlin has no excuse to be honest. But it is a large city.
