Thanks John, and as this relates to Ari, as far as I can tell from the "many" sides to this story we are now hearing, is that she had 2 divers that were actually with her--one I believe doing a refresher or equivalent---but in any event, 2 dependent divers. I am also inclined to believe that ARI did not tell the now deceased Chinese girl, that she would watch her or in any way lead her--for one, they did not speak the same language, and for another, Ari already had her hands full with 2 dependent divers, and three....Ari said she had no conversations with the 2 girls herself---though she did say that one of her 2 dependent divers, did tell the surviving girl she could follow them.....and that this made Ari annoyed, in that she did not want any others added....but this is something that can be addressed in the investigation--either the police or a courtroom, will determine what is supported by 1st hand witnesses, and what is not supported.
What I don't see disputed, is that Ari and her 2 dependent divers, plus the buddy of the girl that died, ended up descending without the Chinese girl--and I think it is agreed that this group felt the Chinese Girl was not going to dive --she had gone back to the boat, or was staying on the surface.
This in itself, is a conversation.....If several buddy teams in a loosely formed group, plan on jumping into the water and swimming down a reefline, and one of the divers in this loose group, can't descend due to ear clear issue or whatever, typically the only person this will effect is that person's buddy. If that buddy is a rank novice, then the issue is even more muddied, because they would be of little or no help to the diver on the surface.
Given this aspect of the dive, I don't see how any of us can pass judgement AGAINST Ari.... Either we know nothing close to sufficient to form such a judgement, or, we know enough to suggest that the Chinese girl was not in a dependancy relationship with Ari, due to her remaining on the surface and not descending with the group. We could discuss this concept of "dependancies in a group".
I personally don't think any of us should point to Ari or point to the boat and crew, as we could damage either quite badly in real world terms, and I don't believe any of us know enough about what facts offered are true, and which are not true. This may well be for a court to decide.
We "Can" debate what each of us "Ought to do" if we were to witness a diver on the surface, in a similar situation....and that is where Scubaboard can have a Social Value. That is where we might save someone's life someday......I do not believe our social value ( scubaboard discussions) is in trying to make the determinations as to what accounts offered in this thread are true, and which are not true.....
