There are many cases we could hear from the news of the media that someone who is good hearted tried to help the injured elderly from the accident, but he/she was misunderstood to be the one who hit the elderly. Under this circumstance, the one who helped people became a "bum rap", who will be "good hearted" to help out the situation again in the future? Will you?
I don't know. Generally speaking I would like to help the elders, but when it is a very dangerous accident, maybe I'll just call the police.
