People like that are one of the problems in this world
I have a (seemingly rare?) mentality where I have a natural urge to protect people or take action, and have done so on numerous occasions even though large numbers of people stand there doing nothing. It can be a MASSIVE liability though, which is why I often stay away from places/locations/activities where certain kinds of events might occur.
If a professional on-duty lifeguard doesn’t know CPR that is pretty weird though, even in the third world… Anyone more worldly than me want to comment on how likely that is? If it’s true, what are they even there for?!
It is curious anyway; at least if the person was actually a "lifeguard" at a body of water, they would have training to manage common life-saving-water-related incidents.
(It could certainly be culture related, although I have no local knowledge.) It's like a car-mechanic that doesn't know how to work on cars.
Eh, everyone dies. One presumes she knew the risk and decided it was worth doing. It's not my place to question that judgement.
I somewhat side with this view; if she decided to take the risk, and chance was not on her side, that's on her and perhaps it was worth it to her. There's always a chance I'll die scuba-diving, probably somewhat similar to my chances of dying while driving. However, there are certainly things I can (and have) done to mitigate that risk, such as redundancy, monitoring my mental/physical state, etc.
I'm guessing this woman wasn't wearing a life-jacket. She'd still have some risk of drowning even if she did wear one, but might have cut that chance down significantly.
(I've never snorkeled with a life-jacket, but it seems like you could make it work, with some adjustments.)
I can't speak for diving, but I know if you have not had a seizure for 6 months you can drive legally, and that has to be considered more dangerous.
There's certainly a difference between neglect that is a risk to others, versus a risk to self.
