I find it HORRIBLY distasteful to use the loss of a student in your own dive community to further your opinions on the toxic agency infighting we have in the scuba community at large.
If you do have any factual information about what happened that night, I'm sure we would all appreciate it, as I'm not yet going to attribute blame to even the instructor until I have factual evidence to believe the instructor was at fault.
According to your signature, you are an assistant instructor trainer for SSI, which last I checked is WRSTC.
I really hope you are using your position as someone who is mentoring and bringing up WRSTC instructors to improve the quality of divers in our area.
