Is there a place where I argued against a more detailed sign of the dangers of going into the water?

Actually, yeah, right in that post it's first thing I say could help prevent something like this. that doesn't mean that the parents familiarizing themselves with where they were going isn't also a method that could have helped.

And, once again, they doesn't lay blame at the feet of really anyone. It's an accident. Animal attacks happen are impossible to predict unless your poking an alligator in the eye with a stick. And even then, it might a koala that attacks instead.
