I think I remember that incident. The photographer said that he didn't have time to help the person, or something like that. And, you know, that's a fine response if that's what happened. If someone were to jump in front of an oncoming train there's very little you could do to stop that or help them because of how quickly you'd have to react.
Anyway, I have to think of my own safety first. No sense it putting myself in danger if it's not helping anyone. I mean, I'd want to help. I'm not callous toward human life or anything, but in a dangerous situation I'd rather call the police or someone professional. I think it would be the right thing to do. Even in a not-immediate-danger situation like someone being on drugs in a really bad way, I have to think there's not a whole lot I could do except try to get them to proper help. But I'm not going to do that for every person I see. Like I said, I have to think of my own safety first.
