I lived in NYC through out my entire life and been riding the rails for 30 years or so, I am 32 now, the subways are jammed packed through out the day. If someone is getting jumped on eventually someone will notice and stepped in. Chaim told me 30 years ago or so when a woman was being assaulted and raped by some black beast in the subway. During the day especially in a post 911 era if someone is in trouble there is going to be a few to help. And this is in front of 1000s and 1000s the media also will pick it up saying "you see we all can get along".
