Sadness...truly.
Sir William, I am sorry for your example, yet I have a tendency to agree with Ian, but in the fact the kids have become de-sensitized with vid-games that are graphic, violent, etc.....
I think the problem lies (in your case), in the fact that they were probably shocked that something like that happened in THEIR world, if you take my meaning. It wasn't a game, but something they witnessed, and it was no longer a "game".... My condolences, good Sir....
