I would put this in the same category as helping a drowning person.

Except, of course, the drowning person has a knife or gun and might want to kill you.

re: drowning person has a knife or gun and might want to kill you.

I know from my limited exposure to lifesaving courses that a drowning person is as dangerous to the would-be rescuer as a weapon. I can barely keep myself afloat, let alone a panicked struggling second non-swimmer.
