I don't remember it, Khandro, but then again, why would I? I do remember the Catholic priest who was murdered in his church some years ago, but that was local to me at the time.

I also remember the British woman that was beheaded in Tenerife because I had just got home from Tenerife when it happened.
I often think of two elderly sisters who kept a corner shop and were murdered at Christmas nearly 30 years ago because I knew them. Their murderer has never been found.
The sad fact is there are too many dreadful murders around the world for them all to have an impact on me.
My point about this murderer's mental health is that as far as the reports show he wasn't acting on behalf of any terrorist organisation and it was believed his mental health may have been a factor. I have not and would not suggest that everyone with mental health issues are a danger to society.
