What does this incident show about modern-day society?

I think that there are a lot of lessons to learn from what happened with the woman on the train. I think it also shows something important about modern-day society. Now that most people have smartphones with cameras, incidents like these are able to be easily recorded and shared online, which can result in a similar situation. It also shows how people can easily get carried away in something that they perceive to be right, even if they take it too far.
