At the end of the day there's a divide between those of us who see wanting to have a gun as a kind of sickness and those who see it as a kind of health. I'm just glad to live in apart of the world where most people see it the same way as I do.

However that's a remote kind of thing really, an abstract argument about moral philosophy and so forth.

It isn't too relevant to the real issue. For Americans that must surely be to find ways of minimising the number of occasions where things like this are going to happen, while accepting that, for good or ill, there are going to continue to be an enormous number of guns in your country for a long time to come, maybe for ever.
