Yes, seeing someone being blasted by a shotgun is of course traumatic, as is someone being murdered, or tragically dying. Just look at that sensless murder of that young teacher in London, tragic beyond belief.
Like Geoff, when I was about 8 or 9 a pupil died at school under tragic circumstances. It was announced at school assembly, and we all went about our school day.
Yes we talked about her during the day, but no one "broke down", no one needed counselling or time off, we just got on with the day.
Nowadays there would be a squad of consellors swooping on the place, and no doubt some kids would need time off to "come to terms" with it.
Which really brings me back to what Dave said, were 300 kids really affected by what hapenned, let alone saw it?
We seem to have turned into a society where when something happens everyone has to be "compensated" in some way, or they need to be counselled to get them through it / "come to terms" with it.
Perhaps society has changed, maybe I am considered as uncaring, but at the end of the day a tragedy is still a tragedy.
