No more heroes :(

I was driving along Kalentong the other day on my way to work. I was pretty much stuck in traffic and quite bored when I noticed a commotion to my right, a policeman was chasing down some guy, probably in his early twenties - barefoot - dirty - unwashed long hair with gold streaks. They passed a lot of other people who could have easily stopped the fleeing fugitive. No one dared to help the policeman. Which brings me to the next questions. If I were given the chance, would I have done something to help him? And for that matter, would you?
