I see so many people have different opinions on the purpose of A&I.
Some call it a morbid curiosity. That is rude and judgmental.
IMO, new divers are intensely interested to understand HOW people can end up dying. They want to know what it is that they can do, avoid doing, or the mindset that kills.
Some people speculate, because it really is a problem-solving process. Unfortunately, sometime the speculation includes diver error, and in some cases, the consensus of opinion is that the diver was stupid. It happens. Another description for stupid is "arrogant and complacent".
Divers can learn from some of this speculation, and as long as it is labeled as such, it harms no one. It is a learning tool.
Sometimes the lesson learned is that scheet happens, and that can be the hardest lesson to accept. Many want to put the blame on something. Sometimes, there is just a situation with enough actions that tip the odds against the diver.
It is a real and serious problem when people fail to lay out the story and the poor decisions as they happen. The desire to hide the truth when a diver is . . . arrogant and complacent . . . does NO ONE any good - the lesson is there to be learned.
As long as the discourse is factual, and the speculation is labeled as such, one is NOT being disrespectful. That is someone else' filter.
Anyone who has been through Casualty Officer Assistance training (military, for dealing with family members) learns that the family is often reaching for understand of what happened. When someone fails to follow procedures and it results in death, there is often accusations of cover-up and blamestorming. We learn, "we don't know what s/he was thinking at the time, only that s/he didn't follow procedures". It is not up to us to soften anything, simply state the facts. This is, IMO, good advice for this forum.
