A very sad event with no real winner's.
However, the swiss court's result adopts the following logic;-
let's imagine; your daughter, 23, is driving home, her mobile phone rings and whilst reaching for it she mounts the curb killing a 40 year old woman.
A blatent death by negligence on the part of your daughter. Yes I know that she didn't go out with the intention of killing the woman but she is licenced to drive the car and if you hold a driving licence you have a responsibility of due care.
Now if that woman is my wife, your daughter in my eyes is responsible and I want revenge.
What will I get if I kill her, 4/5 years after parole! GIVEN MY GRIEF, FAIR DON'T YOU THINK!
and where would it stop?
This example is only made to make a point of logic.
My condolences to both parties in this case.
