No matter why they refused to allow him to help, if I was the person drowning, I sure wouldnt look down from the afterlife and say, "Well, yeah, I'm dead now, but at least they followed the rules!". Seriously, I know it was probably a recovery operation rather than rescue at that point, but I sure would want everyone who had any way to help to do so if it was me or my loved one in trouble. This is certainly a CYA society we live in.
