The events of Thursday are a sobering reminder to all of us at Broadcast House, of what we do and why we do it.

As journalists, we are accustomed to reporting violence and tragedy. Like most people, we are not accustomed to being caught in its path.

Thursday we were reminded of the people who, by chance or mis-chance, find themselves on the other end of our cameras. And we have renewed respect for what they face. In the midst of Thursday's events, there was chaos. And we are reminded of how important it is to deliver clear, calm and fair information to those of you who trust us for your news.
