I remember a story a while back, where some guy on a bus in London stood up to some guys who were insulting his girlfriend. He wasn't even getting angry, he stayed calm, but the bastards mobbed him and stabbed him several times with their switchblades, then simply walked off the bus at the next stop. No one made an attempt to stem the bleeding or call an ambulance. He died on the bus surrounded by people who wanted to see the blood. His girlfriend asked one guy who was standing over him to give her his coat so she could cover him up, and the guy just said no. These kind of stories do invoke some pity in me, but it quickly becomes overwhelmed by rage at the people who would do these kinds of things. Christ, I'd like to think in that position I'd at least try to help keep the kid alive, rather than just stand idly by and watch.
