Huh, interesting that you called it a sorry state, then you kind of defended the inaction. Not that I am complaining, I enjoy the fact that you are getting me to think about it more. It is just kind of confusing, as you seem to be both sympathetic to and condemning of the situation.
I've been to cities with homeless people lying around, and I have always been quite content to walk by. But if I saw blood pooling undernearth one of them, I'd be fast to do something about it. The article you posted mention that a guy actually poked at him for a bit, then moved on. That is just downright morbid if you ask me.
