I watched a few of the rescues, and they were all of kids falling out of their floaties and seemingly unable to swim at all. What does it look like when an able swimmer encounters trouble? Would it look the same as the drowning response kicks in?
Also, how do you differentiate the drowning response from someone that's just bad at treading water and floats low in the water? They might both be bobbing just in and out of the water, but one of them can just transition to floating on their back and the other is trying to not drown. (I haven't swam in forever and don't know if I can even swim anymore, but I was reminded of childhood swimming lesson tests.)
