I would NOT expect a stranger to risk their lives for a family member who was trying to end theirs. If it happened that way, I would thank that stranger from the bottom of my heart....but if everyone watched my dad walk out in 45 degree water in SF bay, in no obvious distress and telling everyone to get away from him, WTF do you expect ??? EDIT: Surfers apparently attempted to help this man...and he turned them away. So, at this point, is every other person on the beach supposed to "man up" and swim out to him to try and bring him back? Ninja please!!
