Rubbish!! Of course they do, if they're HONEST!
I will be honest: I would not charge over there on my own, I would be too afraid to do that.
I don´t know about the systems in England, but here I would probably have dialed the equivalent of 999 and NOT gone over there on my own. I think people are being dishonest when they say they would have stormed over there to help!
That said, I have no idea how I would really react in a situation like that, and I don´t think any of us can.
