Oh that’s sad ☹️ the poor guy and his poor family.
Perhaps people around were not strong swimmers and would have put themselves in danger trying to help, the general advice is to wait for the pros so you don’t make work for them right.
Are you doing okay now?
There could be many reasons why people didn't step in, good ones too. Especially if those that were there have never actually swam in that place, they'd have to consider potential underground currents etc. But the likelihood of an emergency crew making it in time to do anything in a situation like this is so slim. They'd also have to consider they were standing around while someone died- or at least I would have been thinking that. Maybe I was protected by not being there, because I can't imagine not trying. And maybe some things are just meant to be like mom always says, my verdict is still out on that lol.
