You're right I was generalising from Scotland/the UK. The definition of Serial Killer being 2 or more unrelating killings. In Scotland there is somewhere between 1 and 3 multiple murders a year, not all of which are serial killings by the strict definition.

In the serial killing figures you show the numbers are overwhelming dominated by the US where the high availability of guns make multiple murders more common - and the number of sexual serial killers much less as a proportion.

In Europe, I stand by my statement that serial killers are overwhelmingly, etc, etc...
