For anyone who has not seen this it is worth watching!
They were going on about the "bystander" effect, where no one wanted to get involved, but I disagree with that. If you look at that video, it took many attempts to get anyone to respond, but you see that in the instance where some DID, all of a sudden people all around joined in. I think that what really happens is that most people are followers, not leaders, so they don't initiate action even they they would otherwise participate. As soon as a leader steps in and takes the first action, then all the others follow.
The bottom line is that if that were your kid, you should pray that a leader type happens to be around or chances are that everyone will just watch.
