video
There are plenty of cases where people have made a "little movie", in circumstances where some might expect everybody to be either in shock, or legging it, or both. When the London Underground was bombed recently, several mobile phone movies were made.
I'm convinced the video is genuine, and all the more sad for that. And above comment is of course, even more sadly, true. As I mentioned in a previous post, none - or very few - of us know how we might behave in this kind of emergency situation. I prefer to think my first inclination would be, wow, I'm still in one piece, let's see what help I can be to those less fortunate.
But maybe the shock factor would make me whip out my phone. But I don't think so.
