According to what I've found out there's only been six fatal accidents

section in the north of the borough is a well-know accident blackspot.
So much so, there's been two GATSO's on one stretch of the road for
several years now. I suspect the criteria can be bent to include any
section of a road in one area whether a particular portion is safe or
not.

As I said before the criteria is based on serious or fatal accidents.
I expect you will find there are a lot more 'serious' accidents
(requiring hospital treatment) in Kingston plus an even larger number
of 'slight' casualties (walking wounded). Just because there are
relatively few deaths doesn't make it "safe" by any stretch of the
imagination. If you ask the Borough or TfL they will be able to give
you the precise justification for the camera at that location. It is
no secret.
