Maybe you didn't read your way in to this thread Howard. A diver dies, and suddenly there is an outcry ( this thread) about how it had to be someone else's fault, that someone else should have known that they were ill or that they were too old or too whatever.
I disagree. If you spill hot coffee on yourself at MacDonalds and get burned, it is your fault, not theirs.
If you dive with a heart condition, this is on you, not the boat.
And in this specific thread, it is way early for any conjecture. When an autopsy is performed and the report released, and we know if it was medical -- or if it was skill level, or an accident....now is just the wrong time to do this.
