This thread has degenerated from a thought provoking and thoroughly reasonable question about protecting people too insipd to protect themselves, into a series of increasingly narrowly defined scenarios that have little or nothing to do with the original question.
What duty do you as an average citizen owe to other average citizens that have not taken the time, interest or effort to protect themselves as you have? That is the question.
Can you step up to that plate and answer it?
