No one helped man getting killed in train

Oddly enough, I think the larger the crowd around a violent act the harder is to jump in to help. It's a combination of thinking someone else will and peer pressure because no one else is moving.

I've intervened when some one was being beat up in junior high. There were two bullies (both girls) the victim (another girl) and me. I didn't even stop to think, and the bullies ran. Yes they had knives, though there hadn't been any cutting.

I watched a three men in a crowd at an outdoor mall push and shove a man and I did no more than call the police. They weren't even armed.

The situation described is in the middle. I would hope that I'd do something, but I don't know.
