Not really sure where your point is about Japan's practises. I don't think I would feel too happy if I am fined for such incident. Not because of financial loss but rather feel betrayed and disappointed by such a system. What about u? How would you feel if the singapore government system sent you a bill in your moment of grief or bill you for the loss of your loved one? If we can show compassion to injured animals, hope the least we can do is show the same compassion to the dead and those grieving. We are suppose to be an educated, civilised and cultured society after all, are we not? Actually, we dun really have to feel anything but the least we can do is not be insensitive and cold about the loss of a human life.
If upon the news of death, all we can think about is 'damn! now i have to go take a bus', then something is quite wrong.
