Without in any way defending the sloppy overhead skills and gear-selection choices shown in the videos Britton has posted, this argument is among the most obnoxious of those I regularly see advanced to "educate" a diver with whose risk choices the "wiser" poster disagrees.
No diver, whether "properly" trained or otherwise, has any right to expect rescue from anyone outside their immediate team should things go wrong. Nor do they have a right to expect someone else to come get their corpse if they die. Personally, I think leaving them in there would serve a number of useful functions, though in certain sites I'm sure the sheer aggregate volume of bodies and gear would eventually cause problems.
But no rescuer has any obligation to go in after someone reported missing/overdue/dead, and those who choose to do so are making their own risk assessment and doing the rescue/corpse recovery of their own free will. It is freely choosing to do a risky dive out of the goodness of their hearts that makes rescuers like Edd Sorensen such heroic bad
s. To the extent the argument is that there are public servants whose job requires them to conduct rescue/recovery dives, I will remain unpersuaded until we start conscriping people into those jobs.
Any claim that "proper" certification negates, rather than reduces, the chance of needing rescue or recovery is laughable, so if potentially putting would-be rescuers/recovery divers at risk was really something we had a moral obligation to consider, we should all be avoiding any dive with the potential for their involvement.
