I have to say that it's a bit of a "Brainy Smurf" kind of behaviour. And putting you at risk to help someone else is really not a smart idea. It's a bit like trying to save someone from drowning when you're not good at swimming. But then again, it worked, and too often do we hear about people in trouble with the crowd doing nothing but taking off their smartphones to make a picture. And everybody deals differently in a given situation. So... live and let live, right?
