Personally, I'd have to say that I am different. If I didn't see emergency vehicles at the scene of an obvious wreck, with obviously injured people, I'd have to say I'd get the hell out my car right after I dialed 911, which is why I find his story hard to believe. It's absurd to think a multitude of human beings would just casually ignore that kind of a disaster and not help without first being persuaded by the injured. I'm sorry, I'm not saying it didn't happen that way, but one has to admit that's a pretty tall story.
It's not quite what Erik was describing, but check out the pretty famous story about Kitty Genovese
who was murdered in Queens in 1964 in plain view of 38 witnesses -- none of whom offered any assistance to her being attacked.
