I am sure you are familiar with "gallows humor".
It serves as a release when very stressful things happen, so maybe just overlook it?
My take is people have been a bit shook up here lately and maybe the dialogue, even "tasteless" cracks is a healthy way for people to manage. One of the things I feel strongly about is that we just have to cut each other more slack than usual when the **** hits the fan.
I must say, I think I learned a lot in the discussions surrounding both accidents, both in the threads and in PM's once the discussion was "too hot to handle". You have to be able to joke around a bit, months later, or too much is pushed underground.
Both people involved in the accidents had/have huge humor.--even the off color
kind.
The Denton Tragedy was particularly well chronicled by a very devoted friend and dive buddy (on TDS) and many dive physiology points have been considered in a very useful way. Ultimately, it does not really matter much exactly what the causes were. That we can consider risks and ways to mitigate them in a constructive conversation is so valuable. The process of doing this together, as members of the dive community is also meaningful. It is not a trial...it is a human process.
