You’re negating the fact that non-suicidal people being rescued will not actively try to harm you or prevent their own rescue once the panic subsides

I’m guessing you have zero experience or training on this subject? Drowning people usually don’t stop panicking until they loose consciousness, or are back on land and have stopped hyperventilating. You literally just put them in a headlock and something to grab at that isn’t you.

You are also conflating suicidal behavior with homicidal behavior, just because someone is having a mental health crisis doesn’t mean they are inherently violent.
