There is a lot of grey here. So much that perhaps some black and white useful results will come out of it after the trial? An impartial(?) jury with no skin in the diving game needs to look at what happened here and inject some common sense into the incestuous little families that spring up in closed communities.
It's not just here that it happens. Look at the little girl that accidentally shot a firearms instructor with a full - auto machine gun. Think that hasn't drawn some lines and brought out the radicals on both sides? The death of anyone, but more especially a child, seems to polarize folks like nothing else.
Had the adult been the one that died from an embolism due to the ascent and the instructor saved the two kids he would still have allegedly run a lousy program, in totally unsuitable conditions for the program given it's intended scope, used bad judgment, been aided in running that lousy program by BSA rules, and someone would still be dead. But it would not have been a child whose parents lied, using a clearance from a medical "professional" who had no idea what the hell he was signing off on, and with a kid who had no business in the water to begin with on SCUBA. Given his history I would have rejected him from my snorkeling classes.
Yet there are some things that given all of the above might have prevented this event, and the situation leading to it from happening at all. Hopefully a jury will see that and, as a result, meaningful changes made. I imagine some will see those changes as an assault on their freedoms, bottom lines, and egos. None of those are a real concern from my vantage point when weighed against the value of a human life.
Even though I consider myself and others to be no more than animated temporary meat sacks housing some form of intelligence(?) with a built in expiration date. One that should not be sped up by the negligence, stupidity, disregard for safe practices, and profit seeking motives of others.
