We have police and media accounts of the perpetrator, describing him as a man from "the country formerly known as Yugoslavia". We do know a particularly predicable scenario for mass attacks on people in public places throughout Europe, North and South America and throughout much of the civilized and uncivilized world. The region of former Yugoslavia that is now called Kosovo has a population just under two million people. The religion and doctrine of life of 1.6 million of these is Islam. Muslims are present in other districts of former Yugoslavia as well. Details are lacking and in a politically correct Germany, digging out the truth remains to be done. Merely labeling the perpetrator as "mentally disturbed" is skirting a far more pertinent story.
