It would seem that to be the officially sanctioned rescuers is not always a guarantee of achieving a successful out come (see USCG Ditches Dolphin during rescue thread).
As a result of such events surely the argument against the ‘volunteers’ that “This event could so easily have turned very ugly very quickly and YOU have to stand back and look at the bigger picture” is diminished!
Maybe volunteers form a significantly larger part of the bigger picture than some would like?
