Well while I, like others , am appalled at the news I cannot agree with the comments criticising the BBC who to my mind give balanced coverage on the whole. As to saying 4 people died, (including the perpetrator) this is surely just a fact. No-one is suggesting we are sorry he died, or that we mourn all th deaths equally. An emotional over-reaction on this site in my view. Sorry! Lets stick with unemotional reporting of facts.
What I do object to, and it happens on all channels, is the reporters asking bystanders over and over again about their reactions. That is time filling. What they saw, yes, is part of the news, as we are trying to piece together what happened, but what the man in the street thinks is not news.
