My attitude as a professional photographer and later as an assistant picture editor is to provide newsworthy images (I'm not saying that this incident is an example of that - a tragic road accident is just that and I suspect the only reason it made the news was her connection to a well-known stage production).
As to having to deal with grieving relatives and wash blood out of my clothes, I have - several times.
Belfast, Londonderry and Armagh during the toubles of the late 70's and 80s, Lebanon and Beirut in the '80s and 90's and Iraq and Afghanistan until I hung my cameras up in 2003 and went behind a desk for a well-earned rest.
It does get to you and I freely admit that more than once I was tempted to down tools and lend a hand rather than record what was going on. But I was there to do a job and I did it to the best of my ability.
As an assistant picture editor in London and later in Singapore, I was frequently sent images that we chose not to put on the boards for reasons of taste or out of compassion for the relatives.
It is possible to photograph an event like this without showing the faces of the victims and without being obtrusive.
I wasn't present at this incident and by the sounds of it, neither was anyone else on this Forum - therefore to speculate further as to the motives of anyone who was present is pointless.
I will say however, that if any of you had come to me as professional photographers with any of the above reasons for not getting an image of a newsworthy event, I would have fired you on the spot. No question.
Cry about it all you like, but that's the nature of the business - if you don't like it, don't get involved.
Maybe this is the difference between amateur photographers and professional news photographers, I don't know.
