西方人救人，也有被被救人控告的危险。西方的Good Samaritan Law就是解决这个问
题的。
Good Samaritan laws are laws or acts protecting those who choose to serve
and tend to others who are injured or ill. They are intended to reduce
bystanders' hesitation to assist, for fear of being sued or prosecuted for
unintentional injury or wrongful death. http://en.wikipedia.org/wiki/Good_Samaritan_law
活雷锋也需要法律来鼓励和保护。
