It was a historic event. Not unfortunately because of its scale. Unpleasant to think about, but in terms of the scale it's not that unusual. I did say it's the worst, probably the worst instant human toll of any crime. And that may be true. But there are terrorist crimes with effects a bit more drawn out that are more extreme, unfortunately. Nevertheless, it's a historic event because there was a change. The change was the direction in which the guns were pointing. That's new. Radically new.
